Kalıcı Delege Nedir?
Token Extensions Program'ın PermanentDelegate mint uzantısı, mint'in
kendisine bir delege yetkisi atar.
Kalıcı delege, o mint için herhangi bir token hesabı için transfer ve yakma işlemlerini yetkilendirebilen bir mint düzeyinde yetkidir. Mint için tüm token hesapları için küresel bir delege görevi görür ve token hesap sahipleri, kalıcı delegeyi kendi token hesaplarından geri alamazlar.
Mint yetkisi ayrıca AuthorityType::PermanentDelegate kullanarak
SetAuthority ile kalıcı delegeyi daha sonra değiştirebilir.
Kalıcı Delege Nasıl Oluşturulur ve Kullanılır
Kalıcı delege oluşturmak ve kullanmak için:
- Mint hesabı boyutunu ve mint ile
PermanentDelegateuzantısı için gereken rent'i hesaplayın. CreateAccountile mint hesabını oluşturun,PermanentDelegate'i başlatın veInitializeMintile mint'i başlatın.- Kalıcı delege tarafından imzalanmış
TransferCheckedveyaBurnCheckedgönderiniz. Token program bu talimatları, token hesabı sahibi tarafından imzalanmış gibi aynı şekilde işler.
Hesap boyutunu hesaplayın
Temel mint artı PermanentDelegate uzantısı için mint hesabı boyutunu
hesaplayın. Bu, CreateAccount'de kullanılan boyuttur.
Rent'i hesaplayın
Mint artı PermanentDelegate uzantısı için gereken boyutu kullanarak rent'i
hesaplayın.
Mint hesabını oluşturun
Hesaplanan alan ve lamport ile mint account oluşturun.
PermanentDelegate'i Başlatma
Mint üzerinde PermanentDelegate uzantısını başlatın.
Mint'i başlatma
Aynı işlemde InitializeMint ile mint'i başlatın.
Token account oluşturma ve token basma
Sahip ve alıcı için token account oluşturun, ardından sahip token account'una token basın.
Kalıcı delege ile transfer
Kalıcı delege tarafından imzalanan TransferChecked ile token transfer
edin.
Komut Sırası
InitializePermanentDelegate, InitializeMint'den önce gelmelidir.
CreateAccount, InitializePermanentDelegate ve InitializeMint
aynı işleme dahil edilmelidir.
