在Solana SPL交易中捆绑多个指令可以减少网络交互和链上成本,使之在同一交易中执行。以下是如何在React应用中使用SolanaWeb3.js库来实现此过程的示例代码:
首先,确保您的应用程序安装了适当的Web3.js库:
npm install @solana/web3.js
然后,将以下代码添加到您的React组件中,以创建SolanaWeb3.js连接和捆绑多个指令的交易:
import { Connection, PublicKey, Transaction, TransactionInstruction } from '@solana/web3.js';
//创建Solana连接
const connection = new Connection('https://api.mainnet-beta.solana.com');
//设置Solana账户公钥
const fromPublicKey = new PublicKey(fromAddress); //将fromAddress设置为您的Solana地址
//设置Solana账户私钥
const fromPrivateKey = new Uint8Array([PRIVATE_KEY_BYTES]); //将PRIVATE_KEY_BYTES设置为您的Solana私钥
//设置接收方地址
const toPublicKey = new PublicKey(toAddress); //将toAddress设置为接收方的Solana地址
//设置指令数据
const data = Buffer.from('Hello, Solana!');
//设置交易指令
const transferInstruction = new TransactionInstruction({
keys: [
{pubkey: fromPublicKey, isSigner: true, isWritable: true},
{pubkey: toPublicKey, isSigner: false, isWritable: true},
],
programId: new PublicKey('TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA'),
data: data,
});
//设置交易费用
const lamports = 100000;
//创建交易
const transaction = new Transaction().add(transferInstruction);
//处理交易签名
const signers = [
{ publicKey: fromPublicKey, secret
