設置權限指引

更改代幣或帳戶的權限。這允許轉移所有權或更新特定的權限類型。

在我們可以設置任何代幣或代幣帳戶的權限之前，我們需要已經完成以下操作：

初始化一個Mint帳戶，並且我們擁有mintAuthority或freezeAuthority
初始化一個Token帳戶或Associated Token帳戶，並且我們擁有該帳戶

原始指令

通過僅使用「原始」指令而不進行任何抽象，以下是更改Mint或Token帳戶權限的方式：

ts
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()指令進行抽象後的相同指令的樣子：

ts
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`)
