Apa Itu Status Akun Default?
Ekstensi mint DefaultAccountState pada Token Extensions Program menetapkan
AccountState awal untuk setiap token account baru yang dibuat untuk mint
tersebut.
Ini paling sering digunakan untuk membuat token account baru dimulai dalam status beku. Token account yang dimulai dalam status beku tidak dapat digunakan sampai freeze authority dari mint mencairkannya.
Cara Membuat Mint dengan Status Akun Default
Untuk membuat mint dengan status akun default:
- Hitung ukuran mint account dan rent yang diperlukan untuk mint dan ekstensi
DefaultAccountState. - Buat mint account dengan
CreateAccount, inisialisasiDefaultAccountState, dan inisialisasi mint denganInitializeMint. - Buat token account untuk mint dan perhatikan bahwa setiap token account baru dimulai dalam status default saat ini.
- Gunakan
UpdateDefaultAccountStateuntuk mengubah status yang seharusnya dimulai oleh token account di masa mendatang.
Hitung ukuran akun
Hitung ukuran mint account untuk mint dasar ditambah ekstensi
DefaultAccountState. Ini adalah ukuran yang digunakan dalam
CreateAccount.
Hitung rent
Hitung rent menggunakan ukuran yang diperlukan untuk mint ditambah ekstensi
DefaultAccountState.
Buat mint account
Buat mint account dengan ruang dan lamport yang telah dihitung.
const client = await createClient().use(generatedPayer()).use(solanaRpc({rpcUrl: "http://localhost:8899",rpcSubscriptionsUrl: "ws://localhost:8900"})).use(rpcAirdrop()).use(airdropPayer(lamports(1_000_000_000n)));const mint = await generateKeyPairSigner();const recipient = await generateKeyPairSigner();const defaultAccountStateExtension = extension("DefaultAccountState", {state: AccountState.Frozen});const mintSpace = BigInt(getMintSize([defaultAccountStateExtension]));const mintRent = await client.rpc.getMinimumBalanceForRentExemption(mintSpace).send();await client.sendTransaction([getCreateAccountInstruction({payer: client.payer,newAccount: mint,lamports: mintRent,space: mintSpace,programAddress: TOKEN_2022_PROGRAM_ADDRESS})]);
Inisialisasi DefaultAccountState
Inisialisasi ekstensi DefaultAccountState pada mint.
const client = await createClient().use(generatedPayer()).use(solanaRpc({rpcUrl: "http://localhost:8899",rpcSubscriptionsUrl: "ws://localhost:8900"})).use(rpcAirdrop()).use(airdropPayer(lamports(1_000_000_000n)));const mint = await generateKeyPairSigner();const recipient = await generateKeyPairSigner();const defaultAccountStateExtension = extension("DefaultAccountState", {state: AccountState.Frozen});const mintSpace = BigInt(getMintSize([defaultAccountStateExtension]));const mintRent = await client.rpc.getMinimumBalanceForRentExemption(mintSpace).send();await client.sendTransaction([getCreateAccountInstruction({payer: client.payer,newAccount: mint,lamports: mintRent,space: mintSpace,programAddress: TOKEN_2022_PROGRAM_ADDRESS}),getInitializeDefaultAccountStateInstruction({mint: mint.address,state: AccountState.Frozen})]);
Inisialisasi mint
Inisialisasi mint dengan InitializeMint dalam transaksi yang sama.
const client = await createClient().use(generatedPayer()).use(solanaRpc({rpcUrl: "http://localhost:8899",rpcSubscriptionsUrl: "ws://localhost:8900"})).use(rpcAirdrop()).use(airdropPayer(lamports(1_000_000_000n)));const mint = await generateKeyPairSigner();const recipient = await generateKeyPairSigner();const defaultAccountStateExtension = extension("DefaultAccountState", {state: AccountState.Frozen});const mintSpace = BigInt(getMintSize([defaultAccountStateExtension]));const mintRent = await client.rpc.getMinimumBalanceForRentExemption(mintSpace).send();await client.sendTransaction([getCreateAccountInstruction({payer: client.payer,newAccount: mint,lamports: mintRent,space: mintSpace,programAddress: TOKEN_2022_PROGRAM_ADDRESS}),getInitializeDefaultAccountStateInstruction({mint: mint.address,state: AccountState.Frozen}),getInitializeMintInstruction({mint: mint.address,decimals: 0,mintAuthority: client.payer.address,freezeAuthority: client.payer.address})]);
Buat token account
Buat token account untuk mint. Karena status default saat ini adalah
Frozen, token account baru dimulai dalam keadaan frozen.
const client = await createClient().use(generatedPayer()).use(solanaRpc({rpcUrl: "http://localhost:8899",rpcSubscriptionsUrl: "ws://localhost:8900"})).use(rpcAirdrop()).use(airdropPayer(lamports(1_000_000_000n)));const mint = await generateKeyPairSigner();const recipient = await generateKeyPairSigner();const defaultAccountStateExtension = extension("DefaultAccountState", {state: AccountState.Frozen});const mintSpace = BigInt(getMintSize([defaultAccountStateExtension]));const mintRent = await client.rpc.getMinimumBalanceForRentExemption(mintSpace).send();await client.sendTransaction([getCreateAccountInstruction({payer: client.payer,newAccount: mint,lamports: mintRent,space: mintSpace,programAddress: TOKEN_2022_PROGRAM_ADDRESS}),getInitializeDefaultAccountStateInstruction({mint: mint.address,state: AccountState.Frozen}),getInitializeMintInstruction({mint: mint.address,decimals: 0,mintAuthority: client.payer.address,freezeAuthority: client.payer.address})]);const [tokenAccount] = await findAssociatedTokenPda({mint: mint.address,owner: recipient.address,tokenProgram: TOKEN_2022_PROGRAM_ADDRESS});await client.sendTransaction([await getCreateAssociatedTokenInstructionAsync({payer: client.payer,mint: mint.address,owner: recipient.address})]);
Perbarui status default account
Gunakan UpdateDefaultAccountState untuk mengubah status default agar token
account di masa mendatang tidak lagi dimulai dalam keadaan frozen.
const client = await createClient().use(generatedPayer()).use(solanaRpc({rpcUrl: "http://localhost:8899",rpcSubscriptionsUrl: "ws://localhost:8900"})).use(rpcAirdrop()).use(airdropPayer(lamports(1_000_000_000n)));const mint = await generateKeyPairSigner();const recipient = await generateKeyPairSigner();const defaultAccountStateExtension = extension("DefaultAccountState", {state: AccountState.Frozen});const mintSpace = BigInt(getMintSize([defaultAccountStateExtension]));const mintRent = await client.rpc.getMinimumBalanceForRentExemption(mintSpace).send();await client.sendTransaction([getCreateAccountInstruction({payer: client.payer,newAccount: mint,lamports: mintRent,space: mintSpace,programAddress: TOKEN_2022_PROGRAM_ADDRESS}),getInitializeDefaultAccountStateInstruction({mint: mint.address,state: AccountState.Frozen}),getInitializeMintInstruction({mint: mint.address,decimals: 0,mintAuthority: client.payer.address,freezeAuthority: client.payer.address})]);const [tokenAccount] = await findAssociatedTokenPda({mint: mint.address,owner: recipient.address,tokenProgram: TOKEN_2022_PROGRAM_ADDRESS});await client.sendTransaction([await getCreateAssociatedTokenInstructionAsync({payer: client.payer,mint: mint.address,owner: recipient.address})]);await client.sendTransaction([getUpdateDefaultAccountStateInstruction({mint: mint.address,freezeAuthority: client.payer,state: AccountState.Initialized})]);
Urutan Instruksi
DefaultAccountStateInstruction::Initialize harus dilakukan sebelum
InitializeMint. CreateAccount,
DefaultAccountStateInstruction::Initialize, dan InitializeMint
harus disertakan dalam transaksi yang sama.
