THORWallet's implementation of XChainJS

Developed / Developing by xchainjs and THORWallet

XChainJS is a library with a common interface for multiple blockchains, built for simple and fast integration for wallets and more.

Interface

The interface is defined here.

Common Interface

A single common interface:

1. Initialise with a valid BIP39 phrase and specified network (testnet/mainnet)
2. Get the address, with support for BIP44 path derivations (default is Index 0)
3. Get the balance (UTXO or account-based)
4. Get transaction history for that address
5. Make a simple transfer
6. Get blockchain fee information (standard, fast, fastest)

Packages

• xchain-binance
• xchain-bitcoin
• xchain-bitcoincash
• xchain-client
• xchain-cosmos
• xchain-crypto
• xchain-doge
• xchain-ethereum
• xchain-litecoin
• xchain-polkadot
• xchain-terra
• xchain-thorchain
• xchain-util

Advanced Features

For wallets that need even more flexibility (smart contract blockchains) the client can be retrieved and the wallet is then free to handle directly.

XChainJS uses following libraries, frameworks and more:

• BitcoinJS
• @binance-chain/javascript-sdk
• @ethersproject
• cosmos-client
• PolkadotJS

Tests

Make sure Jest and Lerna is installed

yarn add --dev jest lerna

Start with

yarn
yarn build

unit

yarn test

Integration Tests

There are a suite of integration test which work against testnet. You will need to specify a phrase which controls testnet coins

export PHRASE="secret phrase here"
yarn e2e

Development

lerna bootstrap

Releasing
