如何在Solana中使用@solana/web3.js从我的自定义令牌中删除铸币授权？

npm install @solana/web3.js

const web3 = require('@solana/web3.js');
const splToken = require('@solana/spl-token');

const connection = new web3.Connection(web3.clusterApiUrl('devnet'));

const walletAddress = new web3.PublicKey('your_wallet_address');
const walletPrivateKey = web3.Keypair.fromSecretKey(Buffer.from('your_wallet_private_key', 'hex'));

const tokenAddress = new web3.PublicKey('your_token_address');
const token = new splToken.Token(connection, tokenAddress, splToken.TOKEN_PROGRAM_ID, walletPrivateKey);

async function revokeMintAuthority() {
  const mintAuthority = await token.getMintAuthority();
  const transaction = new web3.Transaction().add(
    splToken.Token.createRevokeInstruction(
      splToken.TOKEN_PROGRAM_ID,
      tokenAddress,
      mintAuthority,
      []
    )
  );
  const signature = await web3.sendAndConfirmTransaction(
    connection,
    transaction,
    [walletPrivateKey]
  );
  console.log('Transaction signature:', signature);
}

revokeMintAuthority();
