javascript - Solana 中的 "Signature Verification Failed"是什么？

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，您需要传入签名者的 key 对和您正在创建的帐户的 key 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 ，但您仍将拥有您生成的任何帐户 key 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!
});
