Nexus

"A connection or series of connections linking two or more things."

In Phantasma, the Nexus is the entity that binds the whole ecosystem together. It links together the Phantasma mainnet and all associated side-chains, tokens, organizations and dapps.

A developer wishing to connect their project with Phantasma can easily query a node to obtain information about the Nexus contents, using the available REST API.

It is also possible (and recommended) for a developer to deploy their own local Nexus, in order to easily develop their connections with dapps, contracts and any other kind of development and testing.

Chains

Phantasma is not a single blockchain, but rather a collection of multiple chains binded together by the Nexus.
However a main chain exists for each Nexus (either the public Nexus or a local development nexus). This chain has the name 'main' and is the result of the creation of a genesis block along with all default economy assets and organizations.

A developer wishing can easily query a Phantasma node to obtain information about a specific Phantasma chain, using the available REST API.

For deeper diving, the code implementation of a Phantasma chain is available at Github.

Blocks

A chain in Phantasma represents a typical blockchain composed of blocks, where each blocks connects to the previous block via a hash.
The hash of each block is produced from the actual contents of the block, and this together with the linking of the previous block hash is what gives imutability to a blockchain.
In other words, this system ensures that existing data can not be tampered with, making blockchain a unique kind of structure that offers many benefits compared to traditional databases.

Unlike most blockchains who continually generate blocks each X seconds, even if the block is empty, in Phantasma blocks are only generated if transactions are available. This is possible due to the consensus mechanism employed in Phantasma and it helps reducing the storage costs.
The time required to generate a new block can be as little as a few seconds, depending only on the amount of pending transactions. A Phantasma node can be configured with different periods. When the amount of pending transactions is small, it is more space efficient for a Phantasma node to generate blocks less frequently, but packing each one with more transactions.

A developer wishing can easily query a Phantasma node to obtain information about a specific block, using the available endpoint GetBlockByHash.

Blocks are also one of Phantasma objects that can be manipulated in raw format via the GetRawBlockByHash endpoint in the REST API.
Read more about raw data in the section about serialization.

For deeper diving, the code implementation of a Phantasma block is available at Github.

Transactions

A transaction in Phantasma represents a unit of interaction with the ecosystem.
Resumed in a simple way, a transaction is a set of actions that change something in Phantasma chains.

Some examples:

• An user sending assets from one address to another.
• An user interacting with a dapp.
• An user buying a NFT from a market.
• An user transfering an asset from Ethereum into Phantasma via chain swaps.

Each Phantasma transaction will contain inside a small script, that when executed in a virtual machine will tell the nodes what operations the user wanted to do. The user account pays a fee which depends on the transaction complexity, more specifically, the amount and type of operations done within, and results of those operations are then commited, making them permanent.

Transactions are also one of Phantasma objects that can be manipulated in raw format via the GetRawTransaction endpoint in the REST API.

For deeper diving, the code implementation of a Phantasma transaction is available at Github.

Address

A address in Phantasma represents a destination for assets.
Each address holds a specific balance of tokens, along with several custom data on dapps and builtin contracts.

Internally an address is a 34 byte array, where the first byte represents address type and the rest of the bytes store a public key.

In order to display it on a human-readable format, those bytes are then encoded using base58 format. The byte representing the address type is manipulated in order to specify the first letter of the human-readable address. This makes it possible to identify the type of address with a quick glance.

Address types:

• Normal addresses start with 'P' and represent a user account.
  Eg: P2KACviijLauSeNPYDyov9g9Tsqn45eHGw6jCg4D3YzcNsh
• System addresses start with 'S' and can represent contracts, tokens, chains or organizations.
  Eg: S3d7TbZxtNPdXy11hfmBLJLYn67gZTG2ibL7fJBcVdihWU4
• Interop addresses start with 'X' and represent an external address that belongs to other chain (eg: Ethereum or NEO) and are used for chain swaps.
  Eg: X2KK7BD2keGusLwMwuGpd33r1s6Yo3JxYtCbogwDveq2wpZ

The Address is one of the few non-primitive types that have native support in Phantasma Virtual Machine.

Keys

Phantasma uses asymmetric cryptography, also called public-key cryptography for most of it's internals. In simple words, this means that for each public key there is an associated private key. The private key is used to generate signatures, that can be used to mathematically verify that an piece of data was generated by someone who knows the private key of a specific public address, without revealing the private key.

A private key is also the only thing that an user of Phantasma really needs to store in it's own possession, everything else from public key to address and any asset held by the user are stored either in distributed nodes or derived from the private key using mathematical formulas.
Software used to manage private keys for users is called a wallet.

A Phantasma address is used to encode public keys in a human readable format.

For deeper diving, the code implementation of a Phantasma key pair is available at Github.

Signatures

In blockchain terms, a signature is a piece of pseudo-random data that can be used as mathematical proof (when combined with a public address), in order to verify that another specific piece of data was created by a certain private key that matches the specified public key.

A signature is what allows users to sign their own transactions and then allow nodes to validate their authenticity.

There are many different algorithm to generate signatures. Phantasma currently supports EdDSA as it's prefered signing scheme, due to it's higher performance. It also supports ECDsa signatures for compatibility with older generation blockchains, like Bitcoin, Ethereum and NEO.

For deeper diving, the code implementation of a Phantasma signatures is available at Github.

Virtual Machine

The core of Phantasma is built with powerful support for flexibility and customization, and this required the creation of a custom virtual machine to execute both transactions and contracts.

The Phantasma Virtual Machine is on a way comparable to Ethereum Virtual Machine (EVM), in a way that both execute custom code that spends "gas", altough Phantasma implementation is separated and built from zero.

To understand the full scope of the virtual machine requires a bit of development experience and some time studying it.
There is a full section describing the inner works of it.

For deeper diving, the code implementation of the Phantasma Virtual Machine is available at Github.

Accounts

Each user in Phantasma can own one or more accounts, which can hold different types of assets and are used to interact with dapps.

Each account is identified by it's own address and optionally can also have a name associated with it.
The name is a lower-case string without spaces, which can contain letters, numbers and underscore. The length must be between 3 and 15 characters in total.
The account names are integrated deeply into Phantasma inner core, so any place that requires an address can also accept a name instead, which will be automatically resolved into the equivalent address.

An account can also optionally have a contract attached to it, which allows to customize the behaviour of the account, which includes for example support multi-signature wallets.
Also note that all operations done on accounts are done via the builtin account contract

For deeper diving, the code implementation of the acount native contract is available at Github.

Organizations

Phantasma has builtin support for decentralized organizations. The organization system is used to power Phantom Force.

An organization behaves similar to an account, and so it is also identified by it's own address. However the main difference is that it can add other accounts as members of it, and then any operation done by the organization requires signatures from the majority of it's members.

An organization can also optionally have a contract attached to it, which allows to customize the behaviour of the organization, which includes for example custom rules for members and how the assets are transfered.

For deeper diving, the code implementation of the organization is available at Github.

Oracles

Phantasma has builtin support for oracles. In a blockchain that supports contracts, the contracts have their own defined rules, however they can only work with data that is readily available to them, and usually this means the data stored in the chain, like account balances. An oracle is then a data source that allows contracts to obtain data from real world in a secure way.

There are two types of oracles available in Phantasma:

• Native feeds - Those are the oracle data sources that come builtin with Phantasma. It includes supports for fetching prices of different assets, and also transaction fees costs for different platforms. The data itself is gathered by block producers.
• Custom feeds - Those are the oracle data sources that are created for custom data feeds. It allows to connect Phantasma to third-party oracle providers like Chainlink.

Once a contract or transaction does an oracle read request, the data read from an oracle is appended to the current block. This ensures that the chain contents can be reproduced and verified later, using exactly the same data as the first time the block was generated.

For deeper diving, the code implementation of the oracles is available at Github.

Smart Contracts

Phantasma has builtin support for smart contracts. Smart contracts are a set of pre-defined operations and rules that once deployed in a blockchain, are imutable.

Smart contracts in Phantasma are defined by a set of components:

• Name - This is an identifier in same format as account names. Each contract name also has an equivalent system address
• Script - This a binary data blob of compiled code for the Phantasma Virtual Machine.
• Interface - This a list of public methods and events supported by the contract.

Deploying a contract is normally done via a transaction altough can be done in other ways, for example a contract can deploy other contract. Deployment requires an extra cost, besides the normal fees.

For deeper diving, the code implementation of the contracts is available at Github.

Events

When a Phantasma transaction is executed, whoever executed it will want to know whatever really happened, because while with simple transactions the fact that they were accepted is enough to know the result, with more complex transactions different outcomes can happen.
A transaction or contract can then trigger events, which are readable via the API.

A Phantasma event is composed of:

• Kind - This is kind of event, which can be one of the builtin events or a custom event
• Address - The address associated with the event.
• Data - Binary data that depends on the event kind. Can be numbers, strings, structs or any other type.

For custom events used by contracts, the contract interface will define the actual content of the event, to make it easier for third-parties to read and use it.

Tokens

Phantasma has native support for tokens, which represent the different kinds of assets that a blockchain can use for interact with the real world.

Tokens can be divided into two categories:

• Fungible - Usually represent some kind of monetary unit or quantities of something. Each instance of a fungible token is completly indistinguishable from each other.
• Non-Fungible - A non-fungible represents some kind of unique item, for example a game sword or a web domain. Check the section about NFTs for more details.

For deeper diving, the code implementation of the tokens is available at Github.

NFTs

Phantasma native support for tokens also include proper builtin support for non-fungible tokens (aka NFTs), which can be minted on demand, with a single transaction currently being able to mint up to 100 NFTs, at a almost free cost.

Standard

NFTs in Phantasma support the following features:

• TokenID - A unique 256-bit number used to identify a NFT instance.
• SeriesID - A number that specifies which series a NFT instance belongs to.
• MintID - A sequential number that indicates the order in which this instance was minted in it's series.
• ROM - Each NFT instance contains it's own ROM area, where read-only data can reside. This data is saved during mint, and can never be modified. The hash of this data is used to generate an unique ID for the NFT, meaning that each NFT instance must have unique ROM data. The ROM can be used to store what makes each instance unique, for example in a game that uses NFTs for characters, the ROM data could contain the character name and stats.
• RAM - The counterpart to the ROM, the RAM is the data in a NFT that can change over a NFT lifetime.

Both ROM and ROM of a NFT just represent a variable size byte array, it's up for the dapps developers to chose the data structure of this blob. The TOMB compiler abstracts both ROM and RAM into developer friendly custom structs, that make easy to read and write those fields.

A developer wishing can easily query a Phantasma node to obtain information about a specific NFT instance, using the available endpoint GetNFT.

Infusion

Phantasma based NFTs can be infused with other Phantasma NFTs.
Infusion in this sense means that a NFT will contain other NFTs inside it. The NFTs that are inside can be obtained only by burning the parent NFT.
There is no limit, so infusion can be stacked, with multiple NFTs being infused inside other infused NFTs, recursively.
The CROWN NFT is an example of NFTs using infusion.

For deeper diving, the code implementation of the tokens is available at Github.

Staking

Phatasma staking was designed with ease of use and widespread adoption in mind. Paying all transaction fees in SOUL is not feasible and would be very inefficient. Phantasma designed a dual token system solution whereby users who stake SOUL are eligible to receive rewards in the form of KCAL. KCAL is the network resource token and is used to pay fees on every transaction that happens on-chain.

• Each staked SOUL will earn the user 0.002 kcal per day.
• Users who stake more than 50,000 SOUL will earn the title of Soul Master and earn extra rewards from a pool of 125,000 SOUL every month.
• Soul Masters staking for greater than 90 days will receive a special CROWN NFT every 90 days starting from the time of Phantasma's genesis block. Each CROWN NFT boosts the users KCAL generation rate by 5% up to 100% by having twenty.
• CROWN NFT contains a portion of the ecosystem's total KCAL fees for the last 90 days as well as 20% of the ecosystem incentive allocation, evenly distributed to all qualifying wallets.

Storage

Phantasma decentralized storage was designed to enable the deployment of truly decentralized apps and utilize the full power that blockchain technology has to offer. Phantasma decentralized storage uses a file distribution method that makes it possible for developers to deploy dApps which are fully decentralized and hosted on-chain. Therefore, Phantasma dApps are immutable because users simply source the dApp data files from Phantasma's decentralized file storage, not from a website.

• Files on Phantasma's decentralized storage solution are encrypted and distributed across all active block producers and only accessible through controlling a specific private key.
• Every wallet has a specific amount of kilobytes (KB) allocated in proportion to the amount of staked SOUL. Every staked SOUL earns 40 KB of storage, which means that a Soul Master can initially store up to 1.9 GB of data.

Cosmic Swaps

Phantasma's cosmic swap framework is an on-chain liquidity solution which allows anyone to connect to this decentralized exchange system and benefit from the same liquidity pool. Cosmic swaps provide token swaps directly in the connected wallets without users having to go to a centralized exchange.

This framework follows a specific structure for specific wallet addresses to hold a balance of two different tokens. The price of each token is determined by their overall ratio in relation to each other at the current point in time. Users can tap into this address and exchange one of their surplus tokens for the token they require. This decreases the balance of the first token and increases the balance of the second. By having a price mechanism determined by the ratio between the balances in a specific cosmic swap address, any potential arbitrage opportunities that may arise from the difference in price for the tokens in this system will disappear over time as the market will constantly readjust to the equilibrium price level of those tokens across every token exchange provider.

Chain Swaps

Phantasma's next generation on-chain governance system removes the need for forks and other known drawbacks that legacy blockchains may experience when changes are required. Phantasma's governance system allows the blockchain rules to be parameterized and edited on-chain, once consensus is reached. Consensus is reached by running a poll among either the block producers or the whole community. The consensus poll operates in one of three different modes:

• Unanimity: every voter must agree on the same result to reach consensus.
• Majority: the majority of voters must agree on the same result to reach consensus.
• Popularity: the result with the highest number of votes will reach consensus.

Consensus is always reached unless the top two (or more) options receive an equal number of votes.

Side Chains

A dApp running on its own side chain removes the risk that one single dApp could shut down the whole network whenever it's spammed. This gives developers the power they need to build revolutionary dApps with the supported languages C#, Java, Solidity and Python (support for additional programming languages will be added later).

• Phantasma allows infinite side chains to be deployed.
• Main and side chains can validate 10k transactions per block.
• The maximum total transactions per second (TPS) is the amount of side chains plus the main chain multiplied by the maximum TPS of each chain.
• Infinite side chains coupled with the inter-chain technology Phantasma implements in its network allows all chains to be connected.

Governance

Phantasma's next generation on-chain governance system removes the need for forks and other known drawbacks that legacy blockchains may experience when changes are required. Phantasma's governance system allows the blockchain rules to be parameterized and edited on-chain, once consensus is reached. Consensus is reached by running a poll among either the block producers or the whole community. The consensus poll operates in one of three different modes:

• Unanimity: every voter must agree on the same result to reach consensus.
• Majority: the majority of voters must agree on the same result to reach consensus.
• Popularity: the result with the highest number of votes will reach consensus.

Consensus is always reached unless the top two (or more) options receive an equal number of votes.

Governance List values

All values are integers unless specified otherwise.

Validator

Phantasma has adopted a variant of proof-of-stake PoS that requires users to have a stake in the network to become a validator (block producer). Validators are then rewarded with a share of the transaction fees. The validators also use a rotational scheduling per side-chain to define who the active block producer is. This process occurs in parallel for each side chain, allowing for horizontal scaling to boost the theoretical transactions per second of the chain. Each validator is responsible for accepting transactions from Phantasma users, verifying signatures & transaction contents. Each type of block producer will be rewarded differently for providing their computational resources to the Phantasma network:

• Active Block Producers - receive 75% of the inflation of the governance token (SOUL), plus a minimum of 25% of the transaction fees for blocks which they validate.
• Standby Block Producers - receive 25% of the daily inflation of the governance token (SOUL). The Phantasma chain will start with 10 active BPs and 15 standby BPs, and the number of total BPs will increase by 3 every year.

Economy

Dual Token System

Single token systems suffer from an unsolvable problem: Using the ecosystem drains your ownership share of the token supply. You decrease your influence on the evolution of the chain or project the more you use it. A dual token system allows us to escape this flawed design by separating the governance and fuel tokens.

Earning fuel tokens through staking the governance token allows anyone to use the ecosystem without suffering decreasing influence — and that is why we all earn KCAL by staking SOUL. It also allows anyone to opt to acquire the fuel token only if they have no desire to influence the future of the ecosystem, but simply want to play that amazing game or send some NFTs to their friends.

SOUL is the governance token of the Phantasma blockchain, and the evolution of Phantasma is driven by the SOUL holders. SOUL holders earn voting rights, storage allocations on Phantasma's decentralized storage solution, KCAL through staking SOUL, allows you to claim your on-chain wallet name and quarterly CROWNs if you stake more than 50,000 SOUL.

KCAL fuels everything in the Phantasma ecosystem, and is needed for every single type of transaction on the blockchain, giving it a wide range of use cases. In short, anything that happens on the Phantasma blockchain consumes KCAL, and everything that happens on the Phantasma blockchain burns KCAL; Transactions, staking, unstaking, claiming KCAL, cross chain swap transactions, cosmic swaps between native Phantasma assets, minting non fungible tokens, deploying smart contracts, deploying new tokens and more.

For the full details, please refer to this article on the Phantasma Token Economy.

Block Producers

Phantasma is made up of a decentralized network of nodes - also known as Block Producers. These BP's are responsible for validating transactions on the blockchain. The block producers use a rotational scheduling per side-chain to define who the active block producer is. This process occurs in parallel for each side chain, which will allow for horizontal scaling to boost the theoretical TPS of Phantasma Chain. Each block producer is responsible for accepting transactions from Phantasma users, verifying signatures & transaction contents. Once the transaction is accepted, the block producer adds it to the next block

Inflation is important because it incentivizes the growth of the ecosystem. This will inspire developers to build dApps on Phantasma. It also serves the purpose of helping to fund Phantom Force our decentralized developer team and it also pays our block producers. The yearly inflation is coded to be 3%. On top of receiving fees for verifying transactions, block producers receive 2% of the annual 3%, or 0.75% per quarter.

The amount of BPs is based on the amount of side chains & transactions. There will be 10 active BP + 150% standby BPs.All active BPs will rotate over all chains, which results that all active BPs will continuously produce a block for every chain. Every BP can also verify multiple chains at the same time. At the end of every quarter there will be a voting window for people to vote on BPs to become (or remain) an active BP to make sure that the network remains decentralized

In order to become a block producer, you must:

Inflation

SOUL sustains the entire ecosystem through a low 3% annual inflation, in addition to the fixed Soul Master SOUL rewards which amounts to 125,000 SOUL monthly. Of the 3%:

- 1% is allocated to Phantasma’s decentralized developer and core contributor group Phantom Force.

- 1% is allocated to Phantasma’s consensus nodes, the block producers. 75% of this is allocated to active block producers, while the remaining 25% is shared among standby block producers.

- The remaining 1% is distributed to block producers until it has been allocated to various future incentives — at the time of writing 0.2% has already been allocated to the CROWN rewards pool, while the remaining 0.8% remain unallocated. A part of this remainder will be allocated towards sustainable liquidity provider incentives.

- The Soul Master SOUL reward system is a perpetual incentivization of long term loyal token holders.

While the fixed Soul Master rewards are minted and automatically distributed on a monthly basis, the remaining inflation is split into four automatically distributed quarterly allocations.

To sum up the inflation numbers, SOUL starts out with approximately 4.5% annual inflation with one relative (3%) and one fixed (125,000 monthly) component. As time moves towards infinity the fixed portion of the inflation will correspond to a smaller percentage, and SOUL’s annual inflation will be moving towards 3%.

KCAL is generated only through staking SOUL. There is no additional minting or inflationary mechanisms than staking. For each SOUL you stake, you generate 0.002 KCAL every single day.

All transaction types on Phantasma require a KCAL fee, and 50% of every transaction fee is burned.

Smart contract and token deployment require a larger amount of KCAL as deployment fee, pegged to a fiat amount. 100% of this fee is immediatley burned on contract deployment.

In addition, dApp providers are contributing, with GhostMarket burning half their earned KCAL fees, further driving a downwards pressure on the KCAL supply.

The balance between inflationary (staking) and deflationary (burning) measures guard the KCAL token economy, and the ecosystem blossoms the KCAL supply will eventually reach its equilibrium. After this KCAL may potentially becoming deflationary — after which governance proposals can be submitted to avoid a too strong deflationary component draining the available supply.

For the full details, please refer to this article on the Phantasma Token Economy.

Fees

All core chain functionality except smart contract and token deployment charges the user a very low fee of around 0.003–0.005 KCAL, and these values can be adjusted through governance proposals. 50% of every transaction fee is burned, 25% is distributed to block producers and the remaining 25% is distributed to the CROWN reward pool unless the dApp being interacted with requires this portion to be sent to the dApp provider

Smart contract and token deployment comes at an increased cost, pegged to a fiat value by Phantasma’s native oracles. A developer who wishes to deploy a smart contract for his dApp pays a fee of $10 in its KCAL equivalent. The full amount of KCAL is immediately burned on contract deployment.

For a project building on top of Phantasma that needs its own token, a fee of $100 in its KCAL equivalent is charged on token creation — also this 100% burned. The same applies to artists and others who wish to deploy their own NFT minting smart contract to be able to mint $ARTISTNAME NFTs instead of the default $GHOST NFTs native to GhostMarket.

dApp providers may charge additional fees for using their products, such as GhostMarket and uMint's KCAL fees for creating NFTs.

For the full details, please refer to this article on the Phantasma Token Economy.

Bridges

In today's blockchain world, interoperability is important. Traditionally, a user was restricted only to the blockchain they were using and could not communicate to the "outside world". With the advent of oracles and smart contracts, you can now move assets back and forth across different blockchains such as Neo and Ethereum. This gives the user options.

With Phantasma, users can do a 1:1 cross-chain and bi-directional swap of fungible tokens across Neo and Ethereum. This is only possible with a bridge. For example, a bridge allows the user to send ether from the ethereum blockchain to the Phantasma blockchain all the while maintaining the same supply and price on both ends. This is achieved by using oracles and smart contracts. When you are using our wallets (Poltergeist or Ecto) and sending an asset such as ether, you are really sending it to a smart contract. Swapping tokens consists of a two-step process that requires your signature. This process is actually happening when you claim. When you sign, you're confirming the destination address matches the source address. Since your private key is linked to these addresses, it works seamlessly.

The use case of oracles are an important aspect of using a bridge. Oracles feed information from the outside world to the blockchain via smart contracts. For example, if you were to use our bridge to swap ether to Phantasma, our oracles use an API such as cryptocompare to feed information to our smart contracts. Once Cosmic Swaps 2.0 is live, this is how the kcal:soul price ratio will be determined when trading. Additionally, Phantasma uses three API's for Ethereum's blockchain to aggregate gas fees and caches it, adding 20 gwei to the transaction to avoid any stuck swaps in the event a user sets too low of a gas fee for themselves.

Phantom Force

Phantom Force is Phantasma's decentralized community of developers and core contributors who wish to contribute and build the best user experience & ecosystem on Phantasma Chain and within the Phantasma dApps.

Funded by 1/3rd of Phantasma's 3% annual inflation, Phantom Force developers can submit dApp concepts and other proposals for peer review and receive sustainable funding to boost their efforts. All developers are free to reach out to current Phantom Force members if they wish to join the community.

The Phantom Force functions as a DAO.

PhantasmaSDK

One of the many challenges that blockchain developers face today is lack of tools, documentation and software development kits. In order for this technology to go mainstream, we need to have the resources to help onboard as many developers as we can. We believe that building a blockchain isn't enough, but we need to make Phantasma the most developer friendly blockchain out there - and that's why we created our Phantasma SDKs!

Supported Languages

Node

For development of Phantasma applications it is recommended you run a Phantasma node locally. It acts as your own personal blockchain network. The following instructions explain how to do this on Windows. Other operating systems are also supported and instructions can be found in the following section of this document. You can later move to the official test network where multiple nodes are running, in order to test your dapp under a more realistic enviroment.

To get started download a pre-compiled build which comes bundled in the official SDK release: https://github.com/phantasma-io/PhantasmaSDK/releases/latest - the files you need reside under Tools\Spook in the .zip file

Note - you will need .NET runtime 3.1 installed on your desktop https://dotnet.microsoft.com/download

To bootstrap your own test net just run a single instance of Phantasma node using the following arguments:

spook-cli -node.wif=L2LGgkZAdupN2ee8Rs6hpkc65zaGcLbxhbSDGq8oh6umUxxzeW25 -nexus.name=simnet
#To enable the RPC server add this argument to the line above
-rpc.enabled=true

Otherwise you can compile the latest yourself from the source available in this repository.

To compile and publish the source code for you will need the following:

• A Windows PC that suports Visual Studio Community
  • Can be obtained here: https://visualstudio.microsoft.com/downloads/
• An installation of Visual Studio Community with the following extension
  • .NET Desktop Development

Pull or download the following GitHub Repositories

• PhantasmaChain repository
• PhantasmaSpook repository

Ensure both of these sit in the same root directory on your PC and are in folders that match the above. For example:

• C:\PATH\Phantasma\PhantasmaChain
• C:\PATH\Phantasma\PhantasmaSpook

Build and publish the code

• Open Visual Studio
• Open the PhantasmaSpook\Spook.sln solution
• Build the solution
• Publish the Spook.CLI Project

The files needed to run a node will now be in PhantasmaSpook\Phantasma.CLI\Publish

As per above you can run it with the following command:

dotnet Spook.dll -node.wif=L2LGgkZAdupN2ee8Rs6hpkc65zaGcLbxhbSDGq8oh6umUxxzeW25 -nexus.name=simnet
#To enable the RPC server add this argument to the line above
-rpc.enabled=true

Configuration and startup

There are two different possibilities to configure Spook:

Every config paramater is usable in the configuration file and as a cli argument.

• Config file config.json.
• CLI arguments -> overwrite config file values.

Spook can be run in three different modes:

• no interface (default)
• shell ("shell.enabled": true)
• tui ("gui.enabled": true)

Note, you cannot have shell and tui enabled at the same time.

This is what the default configuration looks like:

Example: Simple Sum

Simple contract that sums two numbers and returns the result

contract test {
	public sum(a:number, b:number):number
	{
		return a + b;
	}
}

Example: Conditions

Like most programming languages, it is possible to do conditional branching use if statement.
Logic operators supported include and, or and xor.

contract test {
	public isEvenAndPositive(n:number):bool
	{
		if (n>0 and n%2==0)
		{
			return true;
		}
		else {
			return false;
		}
	}
}

Example: Switch case

Simple contract that sums two numbers and returns the result.

contract test {
	public check(x:number): string {
		switch (x) {
			case 0: return "zero";
			case 1: return "one";
			case 2: return "two";
			default: return "other";
		}                  
	}
}

Example: Simple Counter

Simple contract that implements a global counter (that can be incremented by anyone who calls the contract).
Note that any global variable that is not generic must be initialized in the contract constructor.

contract test {
	global counter: number;

	constructor(owner:address)
	{
		counter:= 0;
	}

	public increment()
	{
		if (counter < 0){
			throw "invalid state";
		}
		counter += 1;
	}
}

Example: Counter per Address

Another contract that implements a counter, this time unique per user address.
Showcases how to validate that a transaction was done by user possessing private keys to 'from' address

contract test {
	import Runtime;
	import Map;

	global counters: storage_map;

	public increment(from:address)
	{
		Runtime.expect(Runtime.isWitness(from), "witness failed");
		local temp: number;
		temp := counters.get(from);
		temp += 1;
		counters.set(from, temp);
	}
}

Example: Strings

Simple contract that shows how to use strings and builtin type methods, string.length() in this specific case.

contract test {
	global val: string;

	constructor(owner:address)
	{
		val := "hello";
		val += " world";
	}

	public getLength():number
	{
		return val.length();
	}
}

Example: Decimals

There is compiler support for decimal numbers.
Note that internally those are converted to Number types in fixed point format.

contract test {
	global val: decimal<4>; // the number between <> is the number of decimal places

	constructor(owner:address)
	{
		val := 2.1425;
	}

	public getValue():number
	{
		return val; // this will return 21425, which is the previous value in fixed point format
	}

	public getDecimals():number
	{
		return val.decimals(); // this returns 4 as result
	}

	public sum(other:decimal<4>):number
	{
		return val + other;
	}

}

Example: Enums

There is compiler support for enumerated value types, that map directly to the Phantasma VM enum type.

// NOTE - like other custom types, it is declared outside the scope of a contract
enum MyEnum { A = 0, B = 1, C = 2}
// if the numbers are sequential, it is ok to ommit them, eg:
//enum MyEnum { A, B, C}

contract test {
	global state: MyEnum;

	constructor(owner:address)
	{
		state := MyEnum.B;
	}

	public getValue():MyEnum
	{
		return state;
	}		
}

Example: Map

The compiler supports generic types, including maps.
Maps are one of the few types that don't have to initialized in the constructor.

	contract test {
		global my_state: storage_map;
	
		constructor(owner:address)
		{
			my_state.set(owner, 42);
		}
	
		public getState(target:address):number
		{
			return my_state.get(target);
		}
	}

Example: String manipulation

The compiler supports generic types, including maps.
Maps are one of the few types that don't have to initialized in the constructor.

contract test {
	import Array;
	
	public toUpper(s:string):string 
	{        
		local my_array: array;		
		
		// extract chars from string into an array
		my_array := s.toArray();	
		
		local length :number := Array.length(my_array);
		local idx :number := 0;
		
		while (idx < length) {
			local ch : number := my_array[idx];
			
			if (ch >= 97) {
				if (ch <= 122) {				
					my_array[idx] := ch - 32; 
				}
			}
						
			idx += 1;
		}
				
		// convert the array back into a unicode string
		local result:string := String.fromArray(my_array); 
		return result;
	}	
}

Example: Random numbers

It is possible to generate pseudo random numbers, and also to control the generation seed.
If a seed is not specified, then the current transaction hash will be used as seed, if available.

contract test {
	import Random;

	global my_state: number;

	constructor(owner:address)
	{
		Random.seed(16676869); // optionally we can specify a seed, this will make the next sequence of random numbers to be deterministic
		my_state := mutateState();
	}

	public mutateState():number
	{
		my_state := Random.generate() % 1024; // Use modulus operator to constrain the random number to a specific range
		return my_state;
	}
}

Example: Transfer Tokens

A contract that takes a payment in tokens from a user.
Showcases how to transfer tokens and how to use macro $THIS_ADDRESS to obtain address of the contract.

contract test {
	import Runtime;
	import Token;

	public paySomething(from:address, quantity:number)
	{
		Runtime.expect(Runtime.isWitness(from), "witness failed");

		local price: number := 10;
		price *= quantity;

		local thisAddr:address := $THIS_ADDRESS;
		Token.transfer(from, thisAddr, "SOUL", price);

		// TODO after payment give something to 'from' address
	}
}

Example: Token Flags

There are also some builtin enums, like TokenFlags.

contract test {
	import Runtime;
	import Token;

	public paySomething(from:address, amount:number, symbol:string)
	{
		Runtime.expect(Runtime.isWitness(from), "witness failed");

		local flags:TokenFlags := Token.getFlags(symbol);

		if (flags.isSet(TokenFlags.Fungible)) {
			local thisAddr:address := $THIS_ADDRESS;
			Token.transfer(from, thisAddr, "SOUL", price);
		}
	}
}

Example: Validation

Runtime.Expect offers a clean way to validate conditions.
The developer of a smart contract must be very careful to ensure that no exploits are possible due to missing validations.

contract test {
	import Runtime;

	public doSomething(from:address)  {
		Runtime.expect(from.isUser(), "expected user address"); // makes sure the address is of 'user' type
		Runtime.expect(Runtime.isWitness(from), "invalid witness"); // makes sure the transaction was signed by 'from' address
		Runtime.expect(Runtime.gasTarget() == $THIS_ADDRESS, "invalid donation"); // makes sure the transaction fees are donated to this contract

		// actually do something after passing all validation
	}
}

Example: Call method

Showcases how a contract method can call other methods.
If a method is declared private, it can't be called by anyone except the actual contract that implements it.

contract test {
	private sum(a:number, b:number) {
		return a + b;
	}

	public calculatePrice(x:number): number
	{		
		local price: number := 10;
		price := this.sum(price, x); // here we use 'this' for calling another method

		return price;
	}
}

Example: Scripts

A script is something that can be used either for a transaction or for an API invokeScript call.
This example showcases a simple script with one argument, that calls a contract.
Note that for scripts with arguments, for them to run properly you will have to push them into the stack before.

script startup {

	import Call;

	code(target:address) {
		local temp:number := 50000;
		Call.contract("Stake", "Unstake", target, temp);
	}
}

Example: Deploy contract script

This example showcases a script that deploys a token contract.

token GHOST {
	...
}
	
script deploy {

	import Token;
	import Module;

	code() {
		local maxSupply:number := 50000;
		local decimals:number := 1;
		local flags:TokenFlags := TokenFlags.None;
		Token.create(@P2KAkQRrL62zYvb5198CHBLiKHKr4bJvAG7aXwV69rtbeSz, "GHOST",  "Ghost Token", maxSupply, decimals, flags, Module.getScript(GHOST),  Module.getABI(GHOST));
	}
}

Example: Minting Script

This example showcases a script that mints an custom NFT.

struct my_rom_data {
	name:string;
	counter:number;
}

script token_minter {

	import Token;

	code(source:address, target:address) {
		local rom_data:my_rom_data := Struct.my_rom_data("hello", 123);
		NFT.mint(source, target, "LOL", rom_data, "ram_can_be_anything");
	}
}

Example: Inline asm

Inline asm allows to write assembly code that is then inserted and merged into the rest of the code.
This feature is useful as an workaround for missing features in the compiler.

script startup {

	import Call;

	code() {
		local temp:string;
		asm {
			LOAD $temp "hello"
		}
	}
}

Example: Custom events 1

Showcases how a contract can declare and emit custom events.

contract test {
	event MyPayment:number = "{address} paid {data}"; // here we use a short-form description

	public paySomething(from:address, x:number)
	{		
		Runtime.expect(Runtime.isWitness(from), "witness failed");

		local price: number := 10;
		local thisAddr:address := $THIS_ADDRESS;
		Token.transfer(from, thisAddr, "SOUL", price);

		emit MyPayment(from, price);
	}
}

Example: Custom events 2

A more complex version of the previous example, showcasing custom description scripts.

description payment_event {

	code(from:address, amount:number): string {
		local result:string := "";
		result += from;
		result += " paid ";
		result += amount;
		return result;
	}
}

contract test {
	event MyPayment:number = payment_event; // here we use a short-form declaration

	// everything else would be same as previous example
}

Example: Custom events 3

A yet more complex version of the previous examples, showcasing custom description scripts and also struct declarations.

struct my_event_data {
	amount:number;
	symbol:string;
}

description payment_event {

	code(from:address, data:my_event_data): string {
		local result:string := "";
		result += from;
		result += " paid ";
		result += data.amount;
		result += " ";
		result += data.symbol;
		return result;
	}
}

contract test {
	event MyPayment:my_event_data = payment_event; // here we use a short-form declaration

	// everything else would be same as previous examples
}

Example: Trigger 1

A contract example showcasing triggers.
In this example, this account will only accept transfers of KCAL and reject anything else.

contract test {

	trigger onReceive(from:address, symbol:string, amount:number)
	{
		if (symbol != "KCAL") {
			throw "can't receive asset: " + symbol;
		}

		return;
	}
}

Example: Triggers 2

Another contract example showcasing triggers.
In this example, any asset sent to this account will be auto-converted into SOUL.

contract test {

	trigger onReceive(from:address, symbol:string, amount:number)
	{
		if (symbol != "SOUL") {
			Call.contract("Swap", "SwapTokens", from, symbol, "SOUL", amount);
		}

		return;
	}
}

Example: Method variables

It is possible to use methods as variables.

contract test {

	import Runtime;
	import Map;

	global _counter:number;

	global _callMap: storage_map>;

	constructor(owner:address)
	{
		_counter := 0;
	}

	public registerUser(from:address, amount:number)
	{
		local target: method
;

		if (amount > 10) {
			target := incCounter;
		}
		else {
			target := decCounter;
		}

		_callMap.set(from, target);
	}

	public callUser(from:address) {
		local target: method
 := _callMap.get(from);

		Call.method(target, from);
	}

	private incCounter(target:address) {
		_counter += 1;
	}

	private subCounter(target:address) {
		_counter -= 1;
	}
}

Example: Tasks

A task allows a contract method to run periodically without user intervention.
Tasks can't have parameters, however you can use Task.current() along with a global Map to associate custom user data to each task.

contract test {
	import Time;
	import Task;

	global victory:bool;
	global deadline:timestamp;

	constructor(owner:address) {
		victory := false;
		time := Time.now() + time.hours(2);
		Task.start(checkResult, owner, 0, TaskFrequency.Always, 999);
	}

	task checkResult()  {
		if (victory) {
			break;
		}

		local now: timestamp := Time.now();

		if (time >= deadline) {
			break;
		}

		continue;
	}

	public win(from:address)
	{
		victory := true;
	}
}

Example: Multi-signature

Yet another contract example showcasing triggers.
In this example, a multi-signature account is implemented.

contract test {

	global owners: storage_list
;

	constructor(owner:address)
	{
		owners.add(owner);
	}

	private validateSignatures() {
		local index:number := 0;
		local count:number := owners.count();

		while (index < count) {
			local addr:address := owners.get(index);
			if (!Runtime.isWitness(addr)) {
				throw "missing signature of "+addr;
			}
		}
	}

	public isOwner(target:address):bool {
		local index:number := 0;
		local count:number := owners.count();

		while (index < count) {
			local addr:address := owners.get(index);
			if (addr == target) {
				return true;
			}
		}

		return false;
	}

	public addOwner(target:address) {
		Runtime.expect(!isOwner(target), "already is owner");
		validateSignatures();
		owners.add(target);
	}

	trigger onSend(from:address, symbol:string, amount:number)
	{
		validateSignatures();
	}
}

Example: Fungible Token

Showcases how to implement a fungible token (eg: the Phantasma equivalent to an Ethereum ERC20).

token DOG { // this defines the token symbol as DOG
	import Runtime;

	property name:string = "Dog Token";

	property isFungible: bool = true;

	property isDivisible: bool = true;
	property decimals:number = 8; // required only if isDivisible is true
	
	property isTransferable: bool = true;
	property isBurnable: bool = true;
	
	property isFinite: bool = false;
	//property maxSupply: number = 1000000; // required only if isFinite is true
	
	global _admin: address;
	
	constructor(owner:address)	{
		_admin := owner;
	}

	// allows the token to be upgraded later, remove this trigger if you want a imutable fungible token
	trigger onUpgrade(from:address) 
	{
		Runtime.expect(Runtime.isWitness(_admin), "witness failed");
		return;
	}
	
	// its possible to also add more triggers, custom methods etc
}

Example: NFTs

Showcases how to implement an NFT, showcasing all details including ROM, RAM and token series.

When creating an NFT, they must have 4 default properties implemented and they're:

1. name, returns the name of the NFT
2. description, returns the descriptions of the NFT
3. imageURL, returns the image URL of the NFT
4. infoURL, returns the info URL of the NFT

struct luchador_rom
{
	genes:bytes;
	name:string;
}

struct luchador_ram
{
	experience:number;
	level:number;
}

struct item_rom
{
	kind:number;
	quality:number;
}

struct item_ram
{
	power:number;
	level:number;
}

token NACHO {
	global _owner: address;

	const LUCHADOR_SERIES: number = 1;
	const LUCHADOR_SUPPLY: number = 100000;

	const ITEM_SERIES: number = 2;
	const ITEM_SUPPLY: number = 500000;

	property name: string = "Nachomen";

	property isBurnable: bool = true;
	property isFinite: bool = true;
	property isFungible: bool = false;
	property maxSupply: number = LUCHADOR_SUPPLY + ITEM_SUPPLY;

	nft luchador {

		property name: string {
			return _ROM.name;
		}

		property description: string {
			return "Luchador with level " + _RAM.level;
		}

		property imageURL: string {
			return "https://nacho.men/img/luchador/"+ _tokenID;
		}

		property infoURL: string {
			return "https://nacho.men/api/luchador/"+ _tokenID;
		}
	}

	nft item {

		property name: string {
			switch (_ROM.kind)
			{
				case 1: return "Potion";
				case 2: return "Gloves";
				default: return "Item #" + _ROM.kind;
			}
		}

		property description: string {
			return "Item level " + _RAM.level;
		}

		property imageURL: string {
			return "https://nacho.men/img/item/"+ _tokenID;
		}

		property infoURL: string {
			return "https://nacho.men/api/item/"+ _tokenID;
		}
	}	

	constructor (addr:address) {
		_owner := addr;
		// at least one token series must exist, here we create 2 series
		// they don't have to be created in the constructor though, can be created later
		NFT.createSeries(_owner, $THIS_SYMBOL, LUCHADOR_SERIES, LUCHADOR_SUPPLY, TokenSeries.Unique, luchador);
		NFT.createSeries(_owner, $THIS_SYMBOL, ITEM_SERIES, ITEM_SUPPLY, TokenSeries.Unique, item);
	}
}

Example: Call contract from another contract

Example showcasing calling contract storage directly from another contract.
Basic version where another storage map is called, and this value is incremented and stored in another contract storage.

contract test {

	import Map;
	import Storage;
	import Call;

	global counters: storage_map;

	private getContractCount(tokenId:number):number {
	
		local count:number := Call.interop("Map.Get",  "OTHERCONTRACT", "_storageMap", tokenId, $TYPE_OF(number));
		return count;
		
	}

	public updateCount(tokenID:number) {
	
		local contractCounter:number := this.getContractCount(tokenID);
		contractCounter += 1;
		counters.set(tokenID, contractCounter);
		
	}

	public getCount(tokenID:number):number {
	
		local temp:number := counters.get(tokenID);
		return temp;
		
	}
}

Javascript Library

If you are a web dapp developer, you will be able to connect your dapp to Phantasma by downloading the Javascript library and integrating it with your code. If you are creating a Unity or .NET based dapp, you will find a Phantasma Link library client here.
In case you face issues using those libraries, please ask for support in the Phantasma Discord group.

Sample Code

Add links to both Phantasma.js and Phantasma.css files (the actual paths may differ, depending on where you install them).

  <link href="phantasma/phantasma.css" rel="stylesheet">
  <script src="phantasma/phantasma.js"/>

Add a login button HTML code somewhere in your web page.

	<div class="col-md-4 text-center">
		<button type="button" class="btn btn-lg" onclick="loginToPhantasma()">Login</button>
	</div>

Add a Javascript function called loginToPhantasma() somewhere in your web page.

let mydappName = 'mydapp';
let requiredVersion = 2;
let link = new PhantasmaLink(mydappName); // here we instantiate a Phantasma Link connection

function loginToPhantasma() {
	link.login( function(success) {
		if (success) {
			console.log('Connected to account ' + link.account.address + ' via ' + link.wallet);
		}
	}, requiredVersion);
}

After login callback happens, if successful you will get back an account object with several fields.

Field	Description
link.account.name	Account name (or anonymous if no name registered)
link.account.address	Phantasma address
link.account.avatar	Image data (in base64 format, you can use this directly in a element)
link.account.external	External blockchain address if available (eg: Ethereum, BSC, NEO)
link.token	Phantasma Link token, save this to persist connection over a session
link.wallet	Name of the current wallet / connector (eg: Poltergeist, Ecto)

Authorize

Connects a dapp to a wallet. The user must have a wallet installed and open, so that it displays an authorization prompt for the connection.

Parameters

1. stringDapp name / identifier
2. int Phantasma Link Version requested (can be either 1 or 2).

Returns

Authoriziation - A Authoriziation object, or error if the information is invalid.

• wallet: string - Wallet Address.
• nexus: string - Network name (nexus).
• dapp: string - Name of the dApp.
• token: string - Authorization token (can be saved for resuming the connection later
• version: int - Version of the Phantasma Link connected.

getAccount

Returns the account name and balance of given address.

Parameters

1. string Platform requested.

Returns

Account - A Account object, or error if address is invalid.

• alias: string - Wallet name.
• address: string - Account address.

Parameters

1. string Byte array containg data to be signed.

Returns

• bytes: string - Signed data.
• bytes: string - Pad bytes (random bytes prepended to the original bytes).

signTx ( Signed Transaction )

Signs a transaction.

2. string Signature Kind.
3. string Chain.

Returns

Hash - A transaction hash, or error if transaction went wrong.

• result: string - Hash address to the transaction.

invokeScript

Invokes a script on the VM

Parameters

1. string Chain that the script needs to run
2. byte[] The script call in bytes.

Returns

Byte[] - A Byte array object with the return from the script, or error if something wents wrong.

• result: string - Return of the method.

writeArchive

Writes an Archive chunk.

Parameters

1. Hash Hash of the block.
2. int Block index .
3. byte[] Data to write to archive

Returns

Archive - A Archive object, or error if address is invalid.

• address: string - Given address.

Architecture

The Phantasma VM is a simple contained register-based virtual machine that executes scripts for the transactions (and also other situations).
Besides the registers, it also contains an additional stack that is used to pass arguments from a context to another.
The support for multiple contexts is used to provide isolation between different parts of the code, increasing the VM security.
The builtin registers allows to implement turing complete languages, including loops and private sub-routines, as implemented in TOMB. In order to access features specific to Phantasma, interactions with external code are possible via the "interop" calls system, which also uses the stack to pass arguments and call native methods (currently implemented in C#)

For deeper diving, the code implementation of the Phantasma Virtual Machine is available at Github.

Types

The registers for the Phantasma VM at each moment in execution time can hold values for one of the following types.

Opcodes

Assembler

There is an assembler C# library included in the Phantasma Chain repository.
However at the current moment there is nothing useful that can be compiled into an assembler tool binary.
(TODO Someone code this, should be quite easy based on the existing code).

Interop

The interop calls work as a brige that allows the VM scripts to access Phantasma features written in native code.

To do an interop call, a script should push all necessary arguments into the stack, put a method name into a register then use the CTX opcode followed by the SWITCH opcode.

As interop calls do more work than normal opcodes, the gas cost is usually much larger than simpler operations.

For deeper diving, the code implementation of the interop calls is available at Github.

Smart contract development

Spook setup (test enviroment)

1. Get latest Spook code
2. Build it using Visual Studio
3. Copy config_testnet.json to the build folder and rename it config.json
4. Make sure that "shell.enabled" is set to true in config.json

Getting test assets (SOUL and KCAL)

1. Download Poltergeist
2. Open the Poltergeist wallet, go to settings and change network to "localnet"
3. Grab the testnet private key (WIF) from the Spook config.json file (“node.wif”, eg: L2LGgkZAdupN2ee8Rs6hpkc65zaGcLbxhbSDGq8oh6umUxxzeW25)
4. Import a new account in Poltergeist using that WIF. This account will contain SOUL and KCAL.
5. Create other accounts as you need for testing, and send funds from the first account to the new ones.

Deploying a smart contract

1. Download TOMB compiler
2. Build it using Visual Studio
3. Create a new file called hello.tomb with the following sample code as the content
   

   
   contract hello
   {
   	import Token;
   	import Runtime;
   
   	global admin: address;
   
   	constructor(owner:address)
   	{
   		admin := owner;
   	}
   	
   	trigger onUpgrade(from:address) {
   		Runtime.expect(Runtime.isWitness(admin), "witness failed");
   		return;
   	}
   	
   	public callMe(from:address):number
   	{
   		Runtime.expect(Runtime.isWitness(from), "witness failed");
   		local thisAddr:address := $THIS_ADDRESS;
   		Token.transfer(from, thisAddr, "KCAL", Decimal.convert(10, 5));
   	}
   }
   

4. Compile it using TOMB from the terminal
   

   TOMB.exe 

   Where path is the file to the .tomb file.
5. If the compilation was successful you now will also have a .pvm and an .abi file near your .tomb file (and optionally an .asm and and .debug file)
6. Run Spook (make sure that you enabled the shell)
7. Use the command:
   

   wallet open 

   Where WIF is the private key from a wallet that has at least 50000 SOUL staked
8. Use the command:
   

   wallet deploy 

   Where path is the full path to hello.pvm (or any other contract you want to deploy)
9. Later if you need to upgrade a contract, use the command:
   

   wallet upgrade 

   Where path is the full path to the .pvm contract you want to upgrade.

Testing smart contract

Once a contract is deployed, you can now interact with it by sending transations to the chain that call methods of the contract.
The easiest way to do is create a simple HTML page and add some contract calls via Phantasma Link.

Another alternative is to use the contract tester tool.

1. Download the repo from Github
2. Open Index.html
3. Choose the API -> Localnet
4. Choose the contract at -> "Select Contract"
5. Choose the contract method at -> "Contract Methods"
6. Connect to your desired wallet Poltergeist or Ecto at the bottom left.
7. Fill the methods and InvokeScript or SendTransaction.

Smart contract development tips

Some tips for developing better smart contracts:

• Make sure you always think of all possible validations and add them at the beginning of your contract methods with Runtime.Expect
• Unless you specifically require an immutable smart contract, we recommend you to add an OnUpgrade trigger to make sure you can expand it as necessary and also fix bugs that might be detected.
• When updating contracts you can't change existing method names or parameters. However you can make existing methods throw a "deprecated" exception or similar if you don't want them to be used again.
• If your contract has a main address responsible for important operations, always add a "updateOwner", "changeAdmin" or equivalent method, to protect you in case your private keys get compromised.

Development stages

1. First develop and test it locally via a simnet.
2. After everything seems to work fine move your testing to the next phase by deploying your contract in the global testnet.
3. If everything passed all tests then the final step would to deploy in the mainnet (production).
   Note that currentinly deploying in mainnet requires a developer to stake 50K SOUL. If your team does not hold this amount, an alternative is to talk with someone from Phantom Force to help you deploy.

Simple Wallet tutorial (C#)

Setup enviroment

1. Get latest PhantasmaChain code
2. Create a folder called Phantasma and put the PhantasmaChain folder inside that.
3. Create a new Visual Studio solution inside the Phantasma folder (eg: name it MyWallet)
4. Right click in the solution explorer, select Add > Existing Project, then select Phantasma.Domain
5. Repeat the previous step for: Phantasma.Blockchain, Phantasma.Core, Phantasma.Cryptography, Phantasma.Numerics

Creating a C# program

Open your Program.cs file and edit the using clauses.

using System;
using System.IO;
using System.Linq;
using System.Net;
using System.Threading;
using System.Collections.Generic;
using Phantasma.Cryptography;
using Phantasma.Domain;
using Phantasma.Numerics;
using Phantasma.VM.Utils;
using Phantasma.Blockchain.Contracts;
using Phantasma.Blockchain;
using Phantasma.Core.Types;
using Phantasma.Storage;
using Phantasma.CodeGen.Assembler;
using Phantasma.VM;
// NOTE: not all of those might be used in this tutorial...

Generating private / public key pairs

The most basic feature every wallet needs is a way to generate new wallets (aka creating new private keys) and then from there display a public address to the user.

var myKeys = PhantasmaKeys.Generate(); // generates a 256-bit private/public keypair using C# security crypto functions
Console.WriteLine(myKeys.ToWIF()); // this generates an human-readable private key in WIF format
Console.WriteLine(myKeys.Address); // this prints the human-readable public address

Importing private keys

After private keys are generated, it is also an requirement to be able to import them back at a later time.

var wif = Console.ReadLine();
var myKeys = PhantasmaKeys.FromWIF(wif); // imports a 256-bit private key based on an user provided WIF

Generating a transaction

In Phantasma, every transaction contains a mini-script that instructs the chain what the transaction wants to do.
This allows multiple actions to be done in a single transaction, with more expensive transactions costing more gas.
Besides that, most transactions in Phantasma begin with the AllowGas operation (that is used to specify a gas price and limit) and end with a SpendGas operation (which is used to pay KCAL for the actual transaction).

var nexusName = "mainnet";
var expiration = new Timestamp(Timestamp.Now.Value + 1000);

var script = new ScriptBuilder()
	.AllowGas(myKeys.Address, Address.Null, 100000, 99999)
	// add more operations here
	.SpendGas(myKeys.Address)
	.EndScript();
	
var comment = "MYDAPP1.0"; // comments are currently used as a form of identifiying the dapp sending the transaction, however can be used for other things

var tx = new Transaction(nexusName, "main", script, expiration, comment);
// tx.Mine(ProofOfWork.Minimal); // in some cases due to specific operations might be necessary to do Proof of Work
tx.Sign(myKeys);

// convert the transaction into text format
var rawTx = tx.ToByteArray(true);
var hexRawTx = Base16.Encode(rawTx);

Send transaction to a node via API

Transactions that are serialized in hex format can be sent directly to nodes via the sendRawTransaction API call.

var nodeUrl = "127.0.0.1"; // insert a valid node IP here
var url = nodeUrl + "/api/sendRawTransaction/" + hexRawTx;

if (url.Length > 2040)
{
	throw new Exception("Script is too big");
}

Hash txHash;

using (var wb = new WebClient())
{
	var response = wb.DownloadString(url);

	Console.WriteLine(response);

	if (response.StartsWith("\""))
	{
		response = response.Substring(1, response.Length - 2);
	}

	if (!Hash.TryParse(response, out txHash))
	{
		Console.WriteLine("Failed...");
		return;
	}
}

Console.WriteLine("Confirming...");
Thread.Sleep(1000 * 20);

url = baseUrl + "/api/getTransaction/" + txHash.ToString();
using (var wb = new WebClient())
{
	var response = wb.DownloadString(url);

	Console.WriteLine(response);
}

Console.WriteLine("Finished!");
}

Transfering assets

The simplest kind of Phantasma transaction script is transfering a token from one user to another.

var symbol = "SOUL";
var amount = UnitConversion.ToBigInteger(20.5m); // input is C# decimal
var target = "P2KLBD59YDb4nH3Kbg8mrQw9guWQUGwDkNUqhDH7cY2rtyx"; // could also be an existing named address or contract, eg: "hello_target"
var script = new ScriptBuilder()
	.AllowGas(myKeys.Address, Address.Null, 100000, 99999)
	.TransferTokens(symbol, myKeys.address, target, amount);
	.SpendGas(myKeys.Address)
	.EndScript();

Calling contract methods

Other useful type of Phantasma transaction script is calling a method from a smart contract.

var script = new ScriptBuilder()
	.AllowGas(myKeys.Address, Address.Null, 100000, 99999)
	.CallContract("GFNFT", "updateOwner", Address.FromText("P2KAEq94aWKSh5PERtMCqXn5o9XSZkc2Hk6cQi6ByNzBbYX"));
	.SpendGas(myKeys.Address)
	.EndScript();

How to Create an NFT

An NFT Smart contract is almost like an Smart contract with some specific properties, such as. Instead of the name “contract” it should be used “token”, and the name has a maximum of 4 characters. When creating a token, it needs specific properties, such as:

1. name: The name of the Token.
2. symbol: Symbol of the token, should be equal to the token declaration.
3. isBurnable: To tell if you can mint it.
4. isFinite: If it is finite
5. isFungible: If is Fungible (If it is an NFT, should be equals to false)
6. maxSupply: The maximum supply of that token
7. isTransferable: Allow the NFT/Token to be transfered.
8. isCapped: If there's a Cap.

1. 1. Directly by executing Runtime Methods.
2. 2. Calling a method inside the contract

Inside the contract, it needs a specific method to allow them to be minted

    trigger onMint(from:address, to:address, symbol:string, tokenID:number) 
    {
        local contractSymbol: string := $THIS_SYMBOL;
        Runtime.expect(symbol == contractSymbol, "invalid symbol");
        Runtime.expect(Runtime.isWitness(sponsor), "witness failed");
        return;
    }

1. Mint Directly by executing Runtime Methods example

This you don't call the contract directly, but it will run the method above.

public void GenerateItem(string symbol, ItemROM ROM, ItemRAM RAM, int series = 1)
{
    var myScript = new ScriptBuilder().
        AllowGas(_walletAddress, Address.Null, PhantasmaLinkClient.Instance.GasPrice, 9000).
        CallInterop("Runtime.MintToken", _walletAddress.Text, to.Text, symbol, VMObject.FromStruct(ROM), VMObject.FromStruct(RAM), series).
        SpendGas(_walletAddress).
        EndScript();
    
    var Payload = System.Text.Encoding.UTF8.GetBytes("EXP");
    
    PhantasmaLinkClient.Instance.SendTransaction(DomainSettings.RootChainName, myScript, Payload, (hash, msg) =>
    {
        if (hash != Hash.Null)
        {
            // It works
        }
        else
        {
            // Handle Error
        }
    });
} 

2. Mint Calling a method inside the contract example

Create a simple method inside the contract, for example:

public generateItem(from: address, rom: ItemROM, ram: ItemRAM)
{
    Runtime.expect(Runtime.isWitness(from), "witness failed");
    NFT.mint($THIS_ADDRESS, from, $THIS_SYMBOL, rom, ram, ITEM_SERIES);
}

And then call it from the frontend, for example in C#:

public void GenerateItem(ItemROM rom, ItemRAM ram)
{
    var myScript = new ScriptBuilder().
        AllowGas(_walletAddress, Address.Null, PhantasmaLinkClient.Instance.GasPrice, 9000).
        CallContract(“EXP”, "generateItem", _walletAddress, VMObject.FromStruct(rom), VMObject.FromStruct(ram)).
        SpendGas(_walletAddress).
        EndScript();
 
    var Payload = System.Text.Encoding.UTF8.GetBytes("EXP");
    PhantasmaLinkClient.Instance.SendTransaction(DomainSettings.RootChainName, myScript, Payload, (hash, msg) =>
    {
        if (hash != Hash.Null)
        {
            // It works
        }
        else
        {
            // Handle Error
        }
    });
}

After minting a token, it should appear on your wallet.

How to Update an NFT

There are 2 ways to update an NFT. The only field that can be updated on an NFT is the RAM, the ROM can't be updated.

1. 1. Directly by executing Runtime Methods.
2. 2. Calling a method inside the contract

1. Update by directly by executing Runtime Methods example

This will call directly the chain and update the NFT, only works if there's no validation on the contract regarding the trigger onWrite.

public void UpdateItemRAM(Address from, string symbol, BigInteger nftID, ItemRAM nftRAM)
{
    var myScript = new ScriptBuilder().
        AllowGas(from, Address.Null, PhantasmaLinkClient.Instance.GasPrice, 9000).
        CallInterop("Runtime.WriteToken", from.Text, symbol, nftID, nftRAM).
        SpendGas(from).
        EndScript();
    
    var Payload = System.Text.Encoding.UTF8.GetBytes("EXP");
    
    PhantasmaLinkClient.Instance.SendTransaction(DomainSettings.RootChainName, myScript, Payload, (hash, msg) =>
    {
        if (hash != Hash.Null)
        {
            // It works
        }
        else
        {
            // Handle Error
        }
    });
}

2. Update by calling a method inside the contract example

Create a simple method inside the contract, for example:

public updateItem(from: address, nftID:number, nftRAM:ItemRAM)
{
    Runtime.expect(Runtime.isWitness(from), "witness failed");
    NFT.write(from, $THIS_SYMBOL, nftID, nftRAM);
}

And then call it from the frontend, for example in C#:

public void UpdateItemROM(Address from, BigInteger nftID, ItemRAM nftRAM)
{
    var myScript = new ScriptBuilder().
        AllowGas(from, Address.Null, PhantasmaLinkClient.Instance.GasPrice, 9000).
        CallContract(“EXP”, "updateItem", from.text, nftID, nftRAM).
        SpendGas(from).
        EndScript();
    
    var Payload = System.Text.Encoding.UTF8.GetBytes("EXP");
    PhantasmaLinkClient.Instance.SendTransaction(DomainSettings.RootChainName, myScript, Payload, (hash, msg) =>
    {
        if (hash != Hash.Null)
        {
            // It works
        }
        else
        {
            // Handle Error
        }
    });
}

How to Infuse an NFT

Infusing an NFT means that the NFT can have additional information inside of it. For example, imagine a chest, you infuse it with rewards, but to obtain it then you should open it (burn the NFT) to get reward.

There are 2 ways to infuse an NFT.

1. 1. Directly by executing Runtime Methods.
2. 2. Calling a method inside the contract

1. Infusing by directly by executing Runtime Methods example

This will call directly the chain and infuse the item.

public void InfuseItem(Address from, string symbol, BigInteger nftID, string infuseSymbol, BigInteger value)
{
    var myScript = new ScriptBuilder().
        AllowGas(from, Address.Null, PhantasmaLinkClient.Instance.GasPrice, 9000).
        CallInterop("Runtime.InfuseToken", from.Text, symbol, nftID, infuseSymbol, value).
        SpendGas(from).
        EndScript();
    
    var Payload = System.Text.Encoding.UTF8.GetBytes("EXP");
    
    PhantasmaLinkClient.Instance.SendTransaction(DomainSettings.RootChainName, myScript, Payload, (hash, msg) =>
    {
        if (hash != Hash.Null)
        {
            // It works
        }
        else
        {
            // Handle Error
        }
    });
}

2. Infuse by calling a method inside the contract example

Create a simple method inside the contract, for example:

public infuseItem(from: address, nftID:number, infuseSymbol:string, value:number)
{
    Runtime.expect(Runtime.isWitness(from), "witness failed");
    NFT.infuse(from, $THIS_SYMBOL, nftID, infuseSymbol, value);
}

And then call it from the frontend, for example in C#:

public void InfuseItem(Address from, BigInteger nftID, string infuseSymbol, BigInteger value)
{
    var myScript = new ScriptBuilder().
        AllowGas(from, Address.Null, PhantasmaLinkClient.Instance.GasPrice, 9000).
        CallContract(“EXP”, "infuseItem", from.text, nftID, infuseSymbol, value).
        SpendGas(from).
        EndScript();
    
    var Payload = System.Text.Encoding.UTF8.GetBytes("EXP");
    PhantasmaLinkClient.Instance.SendTransaction(DomainSettings.RootChainName, myScript, Payload, (hash, msg) =>
    {
        if (hash != Hash.Null)
        {
            // It works
        }
        else
        {
            // Handle Error
        }
    });
}

How to Burn an NFT

Burning an NFT means that the NFT can be destroyed / used. To allow the NFT to be burned, it needs to have the Burnable property as true. Like:

property isBurnable: bool := true;

There are 2 ways to Burn an NFT.

1. 1. Directly by executing Runtime Methods.
2. 2. Calling a method inside the contract

1. Burning by directly by executing Runtime Methods example

This will call directly the chain and burn the item.

public void BurnItem(Address from, string symbol, BigInteger nftID)
{
    var myScript = new ScriptBuilder().
        AllowGas(from, Address.Null, PhantasmaLinkClient.Instance.GasPrice, 9000).
        CallInterop("Runtime.BurnToken", from.Text, symbol, nftID).
        SpendGas(from).
        EndScript();
    
    var Payload = System.Text.Encoding.UTF8.GetBytes("EXP");
    
    PhantasmaLinkClient.Instance.SendTransaction(DomainSettings.RootChainName, myScript, Payload, (hash, msg) =>
    {
        if (hash != Hash.Null)
        {
            // It works
        }
        else
        {
            // Handle Error
        }
    });
}

2. Burning by calling a method inside the contract example

Create a simple method inside the contract, for example:

public burnItem(from: address, nftID:number) 
{
    Runtime.expect(Runtime.isWitness(from), "witness failed");
    NFT.burn(from, $THIS_SYMBOL, nftID);
}

And then call it from the frontend, for example in C#:

public void BurnItem(Addres from, string nftID)
{
    var myScript = new ScriptBuilder().
        AllowGas(from, Address.Null, PhantasmaLinkClient.Instance.GasPrice, 9000).
        CallContract(“EXP”, "burnItem", from.text, nftID).
        SpendGas(from).
        EndScript();
    
    var Payload = System.Text.Encoding.UTF8.GetBytes("EXP");
    PhantasmaLinkClient.Instance.SendTransaction(DomainSettings.RootChainName, myScript, Payload, (hash, msg) =>
    {
        if (hash != Hash.Null)
        {
            // It works
        }
        else
        {
            // Handle Error
        }
    });
}

How to get an NFT

When you're developing your Dapp, you need to get the user info by calling the GetAccount method and inside that, in the balances will come the NFT's ID's that the user has. Then you'll need to get the NFT data (ROM and RAM) and then you can use it, as you please.

This is an example to get the NFT information.

For example in C# for Unity

public void GetAccount()
{
    List items = new List();
    
    StartCoroutine(PhantasmaAPI.GetAccount(_walletAddress.Text, (account) =>
    {
        var balances = account.balances;
        foreach (var balance in account.balances)
        {
            foreach (var id in balance.ids)
            {
                GetItem(id, (rom, ram) =>
                {
                    Item tempSetup = new Item(rom, ram, id);
                    item.Add(tempSetup);
                });
            }
        }
    }));
}
     
public void GetItem(string id, Action callback)
{
    StartCoroutine(PhantasmaAPI.GetTokenData("EXP", id, (result) =>
    {
        var bytesROM = Base16.Decode(result.rom);
        var bytesRAM = Base16.Decode(result.ram);
    
        if (int.Parse(result.series) == 1)
        {
            var rom = Serialization.Unserialize(bytesROM).AsStruct();
            var ram = Serialization.Unserialize(bytesRAM).AsStruct();
    
            callback(rom, ram);
        }
    
    }, (error, msg) =>
    {
        Debug.Log("error:" + msg);
    }));
}

The first method GetAccount will get the account from the chain and then check the balances / tokens that the specific account has. After that we go one by one in the IDs that we have and check if that token corresponds from what we were expecting, inside the getItem.

How to get multiple NFTs

When you're developing your Dapp, you need to get the user info by calling the GetAccount method and inside that, in the balances will come the NFT's ID's that the user has. Then you'll need to get the NFT data (ROM and RAM) and then you can use it, as you please.

This is an example to get the NFT information.

For example in C# for Unity

public void GetAccount()
{
    List items = new List();
    
    StartCoroutine(PhantasmaAPI.GetAccount(_walletAddress.Text, (account) =>
    {
        var balances = account.balances;
        PhantasmaAPI.GetNFTs(Program.ContractName, String.Join(",", balance.ids), false, (nftResult) =>
        {
            foreach (var nft in nftResult)
            {
                if (nft.ownerAddress == SOULAddress)
                {
                    try
                    {
                        var bytesROM = Base16.Decode(nft.rom);
                        var bytesRaM = Base16.Decode(nft.ram);
                        var rom = VMObject.FromBytes(bytesROM).AsStruct();
                        var ram = VMObject.FromBytes(bytesRAM).AsStruct();
                        items.Add(new Item(rom, ram));
                    }
                    catch (Exception e)
                    {
                        //continue;
                    }
                }
            }
        });
        
    }));
}

The first method GetAccount will get the account from the chain and then check the balances / tokens that the specific account has. After that we go one by one in the IDs that we have and check if that token corresponds from what we were expecting, inside the getItem.

How to use Interop Calls

The interop calls, can be used to directly interact with contract and with the chain. There's a lot of internal calls that can be used, and you can check them on this link here.

This is an example of an Interop call or Internal Operation.

For example in C# for Unity

public void GenerateItem(string symbol, ItemROM ROM, ItemRAM RAM, int series = 1)
{
    var myScript = new ScriptBuilder().
        AllowGas(_walletAddress, Address.Null, PhantasmaLinkClient.Instance.GasPrice, 9000).
        CallInterop("Runtime.MintToken", _walletAddress.Text, to.Text, symbol, VMObject.FromStruct(ROM), VMObject.FromStruct(RAM), series).
        SpendGas(_walletAddress).
        EndScript();
    
    var Payload = System.Text.Encoding.UTF8.GetBytes("EXP");
    
    PhantasmaLinkClient.Instance.SendTransaction(DomainSettings.RootChainName, myScript, Payload, (hash, msg) =>
    {
        if (hash != Hash.Null)
        {
            // It works
        }
        else
        {
            // Handle Error
        }
    });
}    

How to use Triggers

There's a list of available triggers that you can use. They should start with “on” and then the trigger name, for example onMint. They can be Account Triggers, Token Triggers or Organization Triggers.

On the Account triggers it has:

1. OnMint: This methods will be triggers when you mint.
2. OnBurn: This method will be triggered when you burn that token.
3. OnSend: This method will be triggered when sending that token.
4. OnReceive: This method will be triggered when receiving that token.
5. OnWitness: This method will be triggered when you want to prove that was your account to validate that Transaction.
6. OnUpgrade: This method will be triggered when upgrading that contract/token.
7. OnMigrate: This method will be triggered when migrating.

On the Token triggers it has:

1. OnMint: This method will be triggered when a token is minted.
2. OnBurn: This method will be triggered when a token is burned.
3. OnSend: This method will be triggered when a token is sent.
4. OnReceive: This method will be triggered when a token is received.
5. OnInfuse: This method will be triggered when a token is infused.
6. OnUpgrade: This method will be triggered when a contract is upgraded.
7. OnSeries: This method will be triggered when a series is created.
8. OnWrite: This method will be triggered when NFT.Write is called. (When NFT ram is being updated)
9. OnMigrate: This method will be triggered when token is migrated.
10. OnKill: This method will be triggered when you want to destroy/delete the token.

On the Organization triggers it has:

1. OnAdd: This method will be triggered when adding a contract to the chain.
2. OnRemove: This method will be triggered when removing a contract from the chain.
3. OnUpgrade: This method will be triggered when upgrading a contract in the chain.

Relavent information.

onMint, onBurn, onSeed and onReceive share the same parameters,
Address, Addres, string and a number.

trigger onMint(from:address, to:address, symbol:string, tokenID:number) 
trigger onBurn(from:address, to:address, symbol:string, tokenID:number)
trigger onSeed(from:address, to:address, symbol:string, amount:number)
trigger onReceive(from:address, to:address, symbol:string, amount:number)  

onWitness, onSeries, onUpgrade and OnKill share the same parameter,
Address.

trigger onWitness(from:address)
trigger onSeries(from:address)
trigger onUpgrade(from:address) 
trigger onKill(from:address) 

onMigrate parameters are,
Address and Address.

trigger onMigrate(from:address, to:address)

How to transfer SOUL to a contract

Before sending SOUL or other Token to the contract, make sure you have your account connected, and you have the amount needed for the transaction.

C# Version:

public void TransferTokenToContract()
{
    var contractAddress = "S3dKYEaKggsMTmYE9LwekKJS2E7NbCAhT8TksQLnRDY2QgH";
    var moneyToSend = (BigInteger)UnitConversion.ToBigInteger(1000, GetDecimals("SOUL"));
    var Payload = System.Text.Encoding.UTF8.GetBytes("EXP");
    var script = new ScriptBuilder().
            AllowGas(_walletAddress, Address.Null, PhantasmaLinkClient.Instance.GasPrice, 9000).
            TransferTokens("SOUL", _walletAddress, contractAddress, moneyToSend).
            SpendGas(_walletAddress).
            EndScript();
    
    PhantasmaLinkClient.Instance.SendTransaction(DomainSettings.RootChainName, script, Payload, (hash, msg) =>
    {
        if (hash != Hash.Null)
        {
            // It works

Phantasma Link for Javascript

Phantasam setup (test enviroment)

1. Get latest Spook code
2. Build it using Visual Studio
3. Copy config_testnet.json to the build folder and rename it config.json
4. Make sure that "shell.enabled" is set to true in config.json

Getting test assets (SOUL and KCAL)

1. Download Poltergeist
2. Open the Poltergeist wallet, go to settings and change network to "localnet"
3. Grab the testnet private key (WIF) from the Spook config.json file (“node.wif”, eg: L2LGgkZAdupN2ee8Rs6hpkc65zaGcLbxhbSDGq8oh6umUxxzeW25)
4. Import a new account in Poltergeist using that WIF. This account will contain SOUL and KCAL.
5. Create other accounts as you need for testing, and send funds from the first account to the new ones.

Setup login to the wallet

1. Import the phantasma.js to your folder structure
2. Add <script src="/pathTo/phantasma.js"> </script>
3. Create your own js script or use a <script> </script> on you html file.
4. For example the code used on the OTC application.
   

   let link = new PhantasmaLink("otc"); // The "otc" is the name of your dapp in this case is otc. 
   let linkVersion = 1;
   
   // This example uses a ajax call to the API.
   function loginToPhantasma(providerHint) {
       $("#loginModal").modal("hide");
       console.log("Trying to login to phantasma via " + providerHint);
       link.login(
           function (success) {
               if (success) {
                   $.ajax({
                       url: "login",
                       type: "post",
                       data: { token: link.token, name: link.account.name, connector: link.wallet, provider: providerHint, address: link.account.address },
                       success: function (response) {
                           // Handle correct version
                           if (link.version > 1 && link.nexus != expectedNexus) {
                               bootbox.alert("Invalid nexus, connected to " + link.nexus + " but expected " + expectedNexus);
                               return;
                           }
                           
                           // Handle login successful
                           // Do something here.
                       },
                       error: function (jqXHR, textStatus, errorThrown) {
                           console.log(textStatus, errorThrown);
                       },
                   });
               }
           },
           linkVersion,
           "phantasma",
           providerHint
       );
   }
   
   // Simpler version
   function loginToPhantasma(providerHint) {
     console.log("Trying to login to phantasma via " + providerHint);
     link.login(
         function (success) {
             if (success) {
               // Handle login successful
               // Do something here.
             }else {
               // Error connecting to the wallet.
             }
         },
         linkVersion,
         "phantasma",
         providerHint
     );
   }
   
   

5. The providerHint should be poltergeist if you're using the poltergeist wallet or ecto if you're using the ecto wallet.
6. In your application you should give the user permission to choose which wallet they are using.
7. For example you can call this method.
   

   loginToPhantasma("poltergeist");
   // or
   loginToPhantasma("ecto");
   
   

8. Now you have the connection stablished to the users wallet, and now what can you do?

What can we do with the connection to the wallet?

1. When you login to the user successfully, your PhantasmaLink variable will receive the .account
2. With that you can access to the users information
3. For example inside the link.account you can get this information
   

   {
     address: "P2K6Sm1bUYGsFkxuzHPhia1AbANZaHBJV54RgtQi5q8oK34", // User address
     alias: "TestWallet", 
     avatar: "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgBAMAAACBVGfHAAAAJFBMVEWcnJz////39/etra3e3t6lpaW1tbXn5+fW1tbv7+/Ozs69vb2ss4cPAAAAk0lEQVQoz2OgJWA2QOWnKAqVIfM5BIGgAUlgIUhAAsFnEwSDBLgAC0SgAC7ABBEQhQsYQgSEMQRwa2GHGopu7QaEQxpBfBF0pzsg+3WioKAkkn9ZHcFaAuACRhBDleEaFCECQjBNQYJQoAoVcIQJiCA5Cx4iCIcjHB+IEBCFBigcSMHMRDV1IkJAEiygiBAQYmAAABD5F4JgcTScAAAAAElFTkSuQmCC",
     balances: [ // This is an array of all the balances/coins the user has on their wallet.
     {
       decimals: 8
       symbol: "SOUL"
       value: "94000000000000"
     },
     {
       symbol: "KCAL", 
       value: "9992797430348403", 
       decimals: 10
     }
     ],
     external: "",
     id: 2,
     name: "TestWallet",
     platform: "phantasma",
     success: true,
   }
   
   

4. To send a transaction of SOUL or KCAL you can do something like this:
   

   let payload = "exchange";
   let address = String(link.account.address);
   
   // You need to create a ScriptBuilder so you can call use methods in the blockchain.
   var sb = new ScriptBuilder(); 
   var myScript = sb.
       allowGas(address). // To ask permission to the wallet to use the user gas
       callContract("exchange", "TakeOrder", [address, 
       String(id)]). // Call contract 1st argument is the contractName | 2nd Name of the method you want to call | 3rd is an array of variables that the method receives.
       spendGas(address). // To use the user gas
       endScript();
   
   // Send transaction will 1st ask the wallet to validate the transaction, then will send it to the block chain.
   link.sendTransaction("main", myScript, payload, (script) => // 1st argument is the name of the chain | 2nd the script we created | 3rd the can be the name of the application
   {
     // Do something here.
   });
   

5. When you send a transaction or the user receives tokens you can use the link.fetchAccountInfo(callback), for example:
   

   link.fetchAccountInfo(function(){
     // Handle the updated user info.
   });
   

Usefull things you might need.

1. One of the Usefull methods you might need and it's not implemented yet in the Phantasma.js is the convertToBigInt
   

   function convertToBigInt(symbol, amount) {
     if (!link.account) {
         return 0;
     }
     let balances = link.account.balances;
     var i;
     for (i = 0; i < balances.length; i++) {
         var entry = balances[i];
         if (entry.symbol == symbol) {
             return Math.floor(amount * Math.pow(10, entry.decimals));
         }
     }
     return 0;
   }
   
   

2. Other userfull method is getBalance, symbol is the name of the symbol you want, like SOUL|KCAL
   

   function getBalance(symbol) {
     if (!link.account) {
         return 0;
     }
   
     let balances = link.account.balances;
     var i;
     for (i = 0; i < balances.length; i++) {
         var entry = balances[i];
         if (entry.symbol == symbol) {
             return entry.value / Math.pow(10, entry.decimals);
         }
     }
   
     return 0;
   }
   

3. If you're trying to send BigInts they should be converted to String first.
