JPYC core SDK implements interfaces to interact with JPYCv2 contracts on different chains. Supported chains are Ethereum, Polygon, Gnosis, Avalanche, Astar and Shiden.
Please follow the following steps to configure the SDK.
Install packages.
# yarn
$ yarn add @jpyc/sdk-core
# npm
$ npm i @jpyc/sdk-core
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.
Variable | Description & Instructions |
---|---|
SDK_ENV |
SDK environment. Set to local for local environment or any other sensible string for production environment. |
CHAIN_NAME |
Chain name. Set to one of the following: local , ethereum , polygon , gnosis , avalanche , astar or shiden . |
NETWORK_NAME |
Network name within the specified chain. Set to one of the following: mainnet , goerli , sepolia , amoy , chiado or fuji |
RPC_ENDPOINT |
RPC endpoint to send transactions. |
PRIVATE_KEY |
Private key of an account. |
LOCAL_PROXY_ADDRESS |
Proxy contract address in local environment. |
Initialize an SDK instance that implements abstracted interfaces to the JPYCv2 contracts.
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,
});
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()}`);
