设置权限说明

更改 mint 或账户的权限。这允许转移所有权或更新特定的权限类型。

在我们设置任何代币或代币账户的权限之前，我们需要已经完成以下操作：

初始化一个我们持有 mintAuthority 或 freezeAuthority 的 Mint 账户
初始化一个我们拥有的 Token 账户或 Associated Token 账户

原始指令

通过仅使用“原始”指令而不进行任何抽象，更改 Mint 或 Token 账户的权限将如下所示：

const changeTokenAuthorityInstruction = createSetAuthorityInstruction(
    tokenAccount // account
    keypair.publickey // current authority
    AuthorityType.AccountOwner
    newAuthority.publiKey // new authority
);
 
const changeMintFreezeAuthorityInstruction = createSetAuthorityInstruction(
    mint // account
    keypair.publickey // current authority
    AuthorityType.FreezeAccount
    newAuthority.publiKey // new authority
);
 
const changeMintAuthorityInstruction = createSetAuthorityInstruction(
    mint // account
    keypair.publickey // current authority
    AuthorityType.MintTokens
    newAuthority.publiKey // new authority
);
 
const transaction = new Transaction().add(
    changeTokenAuthorityInstruction,
    changeMintFreezeAuthorityInstruction,
    changeMintAuthorityInstruction
);
 
const signature = await sendAndConfirmTransaction(connection, transaction, [keypair]);
 
console.log(`Token and Mint authority changed! Check out your TX here: https://explorer.solana.com/tx/${signature}?cluster=devnet`);

抽象指令

以下是使用 setAuthority() 指令抽象后的相同指令：

let tx = await setAuthority(
    connection,
    keypair,
    tokenAccount // account
    keypair.publickey // current authority
    AuthorityType.AccountOwner
    newAuthority.publiKey // new authority
);
 
console.log(`Token Account Authority Changed!. Transaction Here: https://explorer.solana.com/tx/${tx}?cluster=devnet`)
 
let tx = await setAuthority(
    connection,
    keypair,
    mint // account
    keypair.publickey // current authority
    AuthorityType.FreezeAccount
    newAuthority.publiKey // new authority
);
 
console.log(`Mint Freeze Authority Changed!. Transaction Here: https://explorer.solana.com/tx/${tx}?cluster=devnet`)
 
let tx = await setAuthority(
    connection,
    keypair,
    mint // account
    keypair.publickey // current authority
    AuthorityType.MintTokens
    newAuthority.publiKey // new authority
);
 
console.log(`Mint Authority Changed!. Transaction Here: https://explorer.solana.com/tx/${tx}?cluster=devnet`)
