Solana发送含Memo的交易报错Node is unhealthy求助

问题概述 #

在Solana中发送包含Memo程序的交易时，CLI和web3.js环境均返回Node is unhealthy错误，已尝试删除重装node_modules，怀疑是RPC节点问题。

CLI命令及报错 #

• 执行的CLI命令：

solana transfer --from ./.cache/solana.json RECIVER_PUBLIC_KEY 0.00001 --allow-unfunded-recipient --url https://api.testnet.solana.com  --fee-payer ./.cache/solana.json  --with-memo hello

• 返回错误：

Error: RPC response error -32005: Node is unhealthy

TypeScript代码及报错 #

代码片段 #

async function sendRawTransaction(message:string):Promise<string>{
    const connection = await new Connection(CONNECTION_STRING);
    let tx = new Transaction().add(
        SystemProgram.transfer({
          fromPubkey: WALLET.publicKey,
          toPubkey: RECIVER_ADDRESS,
          lamports: 0,
        }),
      );
    await tx.add(
        new TransactionInstruction({
          keys: [{ pubkey: WALLET.publicKey, isSigner: true, isWritable: true }],
          data: Buffer.from(message, "utf-8"),
          programId: MEMO_PROGRAM,
        })
    );
    return new Promise((res, rej)=>{
        sendAndConfirmTransaction(connection, tx, [WALLET]).then(s=>{
            console.log(s)
            res(s)
        }).catch(e=>{
            console.log(e)
            rej(e)
        })
    })
}

解决方法 #

• 更换RPC节点：官方公共测试网节点可能负载过高，替换CLI的--url参数或代码中的CONNECTION_STRING为第三方测试网RPC地址。
• 检查节点状态：执行solana cluster-info --url https://api.testnet.solana.com命令，确认官方节点是否处于健康状态。
• 调整交易参数：代码中SystemProgram.transfer设置了lamports:0，部分节点可能限制0转账，尝试设置极小值（如1 lamport）后重试。
• 重试交易：临时节点波动可能导致报错，间隔一段时间后重新发送交易。
• 验证Memo程序ID：确保使用的MEMO_PROGRAM为正确地址Memo1UhkJRfHyvLMcVucJwxXeuD728EqVDDwQDxFMNo，避免地址错误导致交易被拒绝。
