Varsayılan Durum

Varsayılan Hesap Durumu Nedir?

Token Extensions Program'ın DefaultAccountState mint uzantısı, o mint için oluşturulan her yeni token account için başlangıç AccountState değerini ayarlar.

Bu en yaygın olarak yeni token hesaplarının dondurulmuş durumda başlaması için kullanılır. Dondurulmuş durumda başlayan token hesapları, mint'in freeze yetkisi bunları çözene kadar kullanılamaz.

Varsayılan Hesap Durumuna Sahip Mint Nasıl Oluşturulur

Varsayılan hesap durumuna sahip bir mint oluşturmak için:

  1. Mint için gereken mint hesap boyutunu ve rent'i ve DefaultAccountState uzantısını hesaplayın.
  2. CreateAccount ile mint hesabını oluşturun, DefaultAccountState uzantısını başlatın ve mint'i InitializeMint ile başlatın.
  3. Mint için token hesapları oluşturun ve her yeni token hesabının mevcut varsayılan durumda başladığını gözlemleyin.
  4. Gelecekteki token hesaplarının başlaması gereken durumu değiştirmek için UpdateDefaultAccountState kullanın.

Hesap boyutunu hesaplayın

Temel mint artı DefaultAccountState uzantısı için mint hesap boyutunu hesaplayın. Bu, CreateAccount içinde kullanılan boyuttur.

Rent'i hesaplayın

Mint artı DefaultAccountState uzantısı için gereken boyutu kullanarak rent'i hesaplayın.

Mint hesabını oluşturun

Hesaplanan alan ve lamport'larla mint hesabını oluşturun.

Example
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
})
]);

DefaultAccountState'i Başlat

Mint üzerinde DefaultAccountState uzantısını başlatın.

Example
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
})
]);

Mint'i başlat

Aynı işlem içinde InitializeMint ile mint'i başlatın.

Example
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
})
]);

Token hesabı oluştur

Mint için bir token hesabı oluşturun. Mevcut varsayılan durum Frozen olduğundan, yeni token hesabı dondurulmuş olarak başlar.

Example
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
})
]);

Varsayılan hesap durumunu güncelle

Gelecekteki token hesaplarının artık dondurulmuş olarak başlamaması için varsayılan durumu değiştirmek üzere UpdateDefaultAccountState kullanın.

Example
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
})
]);

const mintSpace = BigInt(getMintSize([defaultAccountStateExtension]));

Talimat Sırası

DefaultAccountStateInstruction::Initialize, InitializeMint'den önce gelmelidir. CreateAccount, DefaultAccountStateInstruction::Initialize ve InitializeMint aynı işleme dahil edilmelidir.
