【中文标题】什么是 Solana 中的“签名验证失败”？

【英文标题】：What is "Signature Verification Failed" in Solana?

【问题描述】：

我正在尝试调用 Solana 程序，当我运行 sendAndConfirmTransaction 时，它给了我 Signature Verification Failed，我不知道为什么。

const sendAndConfirmTransaction, clusterApiUrl, Connection = require("@solana/web3.js");

let signer = Keypair.generate();
let anotherKeypair = Keypair.generate();

let transaction = someInstruction(signer, anotherKeypair); 
let connection = new Connection(clusterApiUrl('testnet'));

sendAndConfirmTransaction(
  connection,
  transaction,
  [signer]
);

【参考方案1】：

在 Solana 中，您需要传入 两个签名者的密钥对，和您正在创建的帐户的密钥对。

const sendAndConfirmTransaction, clusterApiUrl, Connection = require("@solana/web3.js");

let signer = Keypair.generate();
let anotherKeypair = Keypair.generate();

let transaction = someInstruction(signer, anotherKeypair); 
let connection = new Connection(clusterApiUrl('testnet'));

sendAndConfirmTransaction(
  connection,
  transaction,
  [signer, anotherKeypair] // <-- If you made the keypair, you probably want it here!
);

如果您使用的是钱包连接库，例如 @solana/wallet-adapter-react，则您没有 signer，但您仍将拥有您生成的任何帐户密钥对：

const  sendTransaction  = useWallet();

const anotherKeypair = Keypair.generate(); 

const signature = await sendTransaction(transaction, connection, 
  signers: [anotherKeypair] // You probably want to pass in the keypair here!
);

【讨论】：

我给这句话+1：In Solana, you need to pass in both the keypairs of the signer, and the keypairs of the accounts you're creating
