Apa Fungsi Menetapkan Otoritas?
Menetapkan otoritas mengubah atau mencabut peran otoritas tertentu pada mint account atau token account.
Mint account dapat menyimpan otoritas mint dan otoritas freeze. Token account
menyimpan owner dan dapat secara opsional menyimpan otoritas close. Setiap peran
mengontrol set izin tertentu, dan menetapkan otoritas ke None secara
permanen menghapus peran otoritas yang dipilih.
Token Extensions Program juga mendefinisikan tipe otoritas tambahan untuk ekstensi tertentu.
Cara Menetapkan Otoritas
Mengubah otoritas menggunakan instruksi SetAuthority dari Token Program.
Setiap panggilan memperbarui satu tipe otoritas pada satu mint account atau
token account. Otoritas saat ini menandatangani perubahan, dan otoritas baru
dapat berupa alamat lain atau None untuk mencabut otoritas yang dipilih
secara permanen.
