Installation

To use the Jamton SDK, you need to install the @jamton/sdk package and some @polkadot dependencies:

$ yarn add @jamton/sdk @polkadot/api-augment @polkadot/api

# or

$ npm i @jamton/sdk @polkadot/api-augment @polkadot/api

Usage

import { Tokens, getApiPromise } from '@jamton/sdk'

const ALICE_ACCOUNT_ID = '5GNJqTPyNqANBkUVMN1LPPrxXnFouWXoe2wNSmmEoLctxiZY'

const api = await getApiPromise(endpoint)

const tokens = new Tokens(api)

// get balance of ALICE
const balance = await tokens.nativeBalance(ALICE_ACCOUNT_ID)

Testing

Run the deterministic unit suite with:

yarn test

Live network checks are kept separate and run serially:

yarn test:integration

The integration suite uses the current JAMTON devnet endpoints by default. Override them when needed:

JAMTON_PARACHAIN_WS=wss://your-parachain-endpoint \
POLKADOT_RELAYCHAIN_WS=wss://your-relaychain-endpoint \
yarn test:integration
