Değiştirilemez Sahip Nedir?
Token Extension Program'ın ImmutableOwner hesap uzantısı, bir token
hesabının sahibini kalıcı hale getirir.
Bir token hesabı ImmutableOwner ile başlatıldığında, sonraki
SetAuthority talimatları onun AccountOwner yetkisini değiştiremez.
İlişkili Token Hesapları
Token Extension Program için Associated Token Program aracılığıyla oluşturulan
associated token account'lar, token hesabında ImmutableOwner özelliğini
otomatik olarak başlatır.
Değiştirilemez Sahip Hesabı Nasıl Başlatılır
Değiştirilemez sahip hesabını başlatmak için:
- Bir mint oluşturun ve başlatın.
ImmutableOwneriçin yeterli alana sahip bir token hesabı oluşturun.InitializeAccountöncesinde token hesabındaImmutableOwnerözelliğini başlatın.- Daha sonra
SetAuthorityile hesap sahibini değiştirme girişimiTokenError::ImmutableOwnerhatasıyla başarısız olur.
Token hesap boyutunu hesaplayın
Temel token hesabı artı ImmutableOwner uzantısı için token hesap boyutunu
hesaplayın. Bu, CreateAccount içinde kullanılan boyuttur.
Rent'i hesaplayın
ImmutableOwner uzantısı için gereken token hesap boyutunu kullanarak
rent'i hesaplayın.
Token hesabını oluşturun
Hesaplanan alan ve lamport ile token hesabını oluşturun.
ImmutableOwner'ı Başlat
Token hesabında ImmutableOwner uzantısını başlatın.
Token hesabını başlat
Token hesabını aynı işlemde InitializeAccount ile başlatın.
Talimat Sırası
InitializeImmutableOwner, InitializeAccount öncesinde gelmelidir.
CreateAccount, InitializeImmutableOwner ve InitializeAccount
aynı işleme dahil edilmelidir.
