什么是 Solana 中的“签名验证失败”？

Question

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]
);

Answer 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!
});
