  • Rust test files for correct account ordering examples
  • Futures Error Reference for detailed error codes

Required Libraries​

npm install @solana/web3.js @solana/spl-token bn.js @coral-xyz/borsh

Basic Connection Setup​

import { Connection, PublicKey, Transaction, Keypair } from '@solana/web3.js';
import * as borsh from '@coral-xyz/borsh';

// 1. Connect to RPC endpoint
const connection = new Connection(
  'https://api.devnet.domichain.io',
  'confirmed'
);

// 2. Program ID (deployed contract address)
const PROGRAM_ID = new PublicKey('HJPxiV5zcxRnUrYMBfGVCnQhmKQ35v5YBxdJ4NHuab5z');

// 3. User wallet
const userWallet = Keypair.fromSecretKey(
  Uint8Array.from([
    /* your secret key */
  ])
);
