Transfer Ücretleri Nedir?
Token Extensions Program'ın TransferFeeConfig mint uzantısı, bu mint için
her transfere bir ücret uygular.
Transfer sırasında:
- Transfer edilen miktar, yapılandırılmış ücret kadar azaltılır
- Alıkonulan ücret, hedef token hesabında izlenir
- Alıkonulan ücretler doğrudan token hesaplarından çekilebilir veya mint'e toplanabilir
withdraw_withheld_authority, toplanan ücretleri bir ücret alıcısı token hesabına taşıyabilir
Token Hesap Uzantıları
Bir token hesabı, TransferFeeConfig içeren bir mint için
başlatıldığında, token hesabı TransferFeeAmount ile başlatılır. Token
hesabı Associated Token
Program
üzerinden oluşturulduğunda, gerekli hesap boyutu hesaplanır ve token hesabı
gerekli boyut ve rent muafiyeti lamportları ile oluşturulur.
Transfer Ücreti Mint'i Nasıl Oluşturulur
Bir transfer ücreti mint'i oluşturmak için:
- Mint hesabı boyutunu ve mint ile
TransferFeeConfiguzantısı için gereken rent'i hesaplayın. CreateAccountile mint hesabını oluşturun,TransferFeeConfiguzantısını başlatın ve mint'iInitializeMintile başlatın.- Mint için token hesapları oluşturun.
TransferFeeAmount, token hesapları için otomatik olarak etkinleştirilir. - Token transferi yapmak ve beklenen ücreti doğrulamak için
TransferCheckedWithFeekullanın.TransferCheckedde çalışır ve hedef token hesabında yapılandırılmış ücreti otomatik olarak alıkoyar. - Alıkonulan ücretleri token hesaplarından doğrudan bir ücret alıcısı token
hesabına taşımak için
WithdrawWithheldTokensFromAccountskullanın; mint'inwithdraw_withheld_authoritytarafından imzalanmalıdır. - Alıkonulan ücretleri token hesaplarından mint hesabına taşımak için izinsiz
HarvestWithheldTokensToMintkullanın, ardından mint hesabının alıkonulan ücretlerini bir ücret alıcısı token hesabına çekmek içinWithdrawWithheldTokensFromMintkullanın; mint'inwithdraw_withheld_authoritytarafından imzalanmalıdır. - İki epoch sonra yürürlüğe girecek bir sonraki transfer ücreti
yapılandırmasını güncellemek için
SetTransferFeekullanın.
Hesap boyutunu hesaplayın
Temel mint için mint hesap boyutunu TransferFeeConfig uzantısıyla birlikte
hesaplayın. Bu, CreateAccount içinde kullanılan boyuttur.
Rent'i hesaplayın
Mint için gereken boyutu TransferFeeConfig uzantısıyla birlikte kullanarak
rent'i hesaplayın.
Mint hesabını oluşturun
Hesaplanan alan ve lamport değerleriyle mint hesabını oluşturun.
TransferFeeConfig'i başlatın
Mint üzerinde TransferFeeConfig uzantısını başlatın.
Mint'i başlatın
Aynı işlem içinde mint'i InitializeMint ile başlatın.
Token hesapları oluşturun ve token basın
Kaynak, alıcılar ve ücret alıcısı için token hesapları oluşturun, ardından kaynak token hesabına token basın.
TransferCheckedWithFee ile Transfer
TransferCheckedWithFee ile token transferi yapın ve beklenen ücreti
doğrulayın.
TransferChecked ile Transfer
TransferChecked ile token transferi yapın. Yapılandırılmış ücret hedef
token hesabında tutulmaya devam eder.
Token hesaplarından tutulan ücretleri çekin
Tutulan ücretleri doğrudan token hesaplarından ücret alıcı token hesabına
taşımak için WithdrawWithheldTokensFromAccounts kullanın.
Tutulan ücretleri mint'e toplayın
Tutulan ücretleri token hesaplarından mint hesabının tutulan ücret biriktirici
alanına taşımak için HarvestWithheldTokensToMint kullanın.
Mint'ten tutulan ücretleri çekin
Toplanan ücretleri mint hesabından ücret alıcı token hesabına taşımak için
WithdrawWithheldTokensFromMint kullanın.
Sonraki transfer ücretini güncelleyin
Sonraki transfer ücreti yapılandırmasını güncellemek için SetTransferFee
kullanın.
Talimat Sırası
InitializeTransferFeeConfig, InitializeMint öncesinde gelmelidir.
CreateAccount, InitializeTransferFeeConfig ve InitializeMint
aynı işleme dahil edilmelidir.
