Asset-tracker NPM

Asset Tracker

Asset tracker is a one-stop library for the user to track their assets and holdings across multiple EVM and Non EVM chains.

This library will be updated continuously with more and more chain support and increasing granularity of data.

Installation and Usage

Installation

Install the library by running the command,

npm install --save asset-tracker

Import the library into your project using,

const assetTracker = require('asset-tracker');

Initialization

This library comes with 2 different classes. One is EVM and other is nonEVM with each class catering to their own set of chains and functionality.

Initialize the classes

// Initialize the EVM class
const tracker = new assetTracker.EVM(evmChain);

// Initialize the non EVM class
const tracker = new assetTracker.nonEVM(nonEvmChain);

Methods

Get Native Asset Balance

Returns the native asset balance of the initialized chain.

const nativeAssetbalance = await tracker.getNativeAssetBalance(address);

address (required) - Address for which the native asset balance is to be fetched. Can be a contract address or an EOA.

Discover Fungible Assets

Scans the address for any fungible asset balances and returns the same.

const fungibleAssets = await tracker.discoverFungibleAssets(address);

address (required) - Address for which the list of fungible assets is to be checked.

Discover Non Fungible Assets (NFTs)

Scans the address for any non fungible assets and returns the same.

const nonFungibleAssets = await tracker.discoverNonFungibleAssets(address);

address (required) - Address for which the list of non fungible assets is to be checked.

Get the list of transactions

Returns the list of transactions for the specified address. The function also accepts an option parameter type which accepts the values incoming or outgoing to filter out the transactions.

const transactions = await tracker.getTransactions({ address, page, limit, type });

address (required) - Address for which the list of transactions is to be fetched.
page (required) - Page number for pagination.
limit (required) - Number of results to be returned in every page for pagination.
type (optional. default = all) - Parameter to filter out the incoming or outgoing transactions. Defaults to all.

Get the token details for a particular fungible token address

Returns the basic info about a particular fungible asset.

const fungibleAssetInfo = await tracker.getFungibleTokenDetails(contractAddress);

contractAddress (required) - Contract address of the fungible token.

Get the token details for a particular non fungible (NFT) token address

Returns the basic info about a particular non fungible asset.

const nonFungibleAssetInfo = await tracker.getNFTDetails(contractAddress);

Switch Chains

Switch between different supported chains. Once the chain is switched, all the subsequent functions will work for this new chain.

switchChain(chainName);

chainName (required) - Name of the new chain to be switched.

Get Supported Chains (filter by function name)

This function will return the list of all the supported chains. The user can pass an optional parameter functionName which will return all the chains that supports this particular functionality.
