Instruksi Set Authority

Mengubah otoritas dari mint atau akun. Ini memungkinkan transfer kepemilikan atau memperbarui jenis otoritas tertentu.

Sebelum kita dapat mengatur otoritas atas token atau akun token apa pun, kita perlu sudah memiliki:

Akun Mint yang telah diinisialisasi di mana kita memegang mintAuthority atau freezeAuthority
Akun Token atau akun Associated Token yang telah diinisialisasi yang kita miliki

Raw Instruction

Dengan menggunakan instruksi "raw" tanpa abstraksi apa pun, beginilah cara mengubah otoritas akun Mint atau Token:

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`);

Abstracted Instruction

Beginilah tampilan instruksi yang sama jika diabstraksikan dengan instruksi setAuthority():

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`)
