@jpyc/sdk-core v1.5.1

JPYC Core SDK

JPYC core SDK implements NodeJS interfaces to interact with JPYCv2 contracts on different chains. Currently, we're supporting Ethereum, Polygon, Gnosis, Avalanche, Astar and Shiden.

💡 Usage

Please follow the following steps to configure SDK.

1. Installation

Install NPM package.

# yarn
$ yarn add @jpyc/sdk-core

# npm
$ npm i @jpyc/sdk-core

2. Environment Variables

Some data, such as configuration variables (e.g., chain name) or sensitive data (e.g., private key), are embedded as environment variables. You need to set the following environment variables.

3. SDK Instantiation

Initialize an SDK instance.

import {
  ChainName,
  Endpoint,
  IJPYC,
  ISdkClient,
  JPYC,
  NetworkName,
  SdkClient,
} from '@jpyc/sdk-core';

// 1. Initialize an SdkClient instance
const sdkClient: ISdkClient = new SdkClient({
  chainName: process.env.CHAIN_NAME as ChainName,
  networkName: process.env.NETWORK_NAME as NetworkName,
  rpcEndpoint: process.env.RPC_ENDPOINT as Endpoint,
});

// 2. Generate an account from a private key
export const account = sdkClient.createPrivateKeyAccount({});

// 3. Generate a client with the account
export const client = sdkClient.createLocalClient({
  account: account,
});

// 4. Initialize an SDK instance
export const jpyc: IJPYC = new JPYC({
  client: client,
});

4. SDK Usage

Use the initialized SDK wherever you would like.

import { jpyc } from './YOUR/PATH/TO/INITIALIZATION/FILE';

// Fetch `totalSupply` from `JPYCv2` contract
const totalSupply = await jpyc.totalSupply();
console.log(`totalSupply: ${totalSupply.toString()}`);
