Solana 中“签名验证失败”是什么意思？

Question

我正在尝试调用 Solana 程序，当我运行时sendAndConfirmTransaction，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，您需要传入签名者的密钥对以及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，您没有signer，但您仍然会拥有您生成的帐户的任何密钥对：

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!
);
