Apa yang Dilakukan Pencairan Token Account?
Pencairan mengubah token account dari status beku kembali ke status terinisialisasi.
Setelah pencairan berhasil, akun dapat mentransfer, membakar, dan menutup token lagi. Hanya freeze authority dari mint yang dapat mencairkan token account.
Cara Mencairkan Token Account
Pencairan token account menggunakan instruksi ThawAccount dari Token
Program.
Instruksi ThawAccount memverifikasi bahwa token account milik mint
tersebut dan bahwa penandatangan adalah freeze authority dari mint, kemudian
mengubah status token account dari beku kembali ke terinisialisasi.
Token account native tidak mendukung pencairan.
