Αποδέσμευση λογαριασμού

Αποδέσμευση λογαριασμού

Η εντολή ThawAccount αντιστρέφει μια παγίωση, αποκαθιστώντας την πλήρη λειτουργικότητα σε έναν παγωμένο λογαριασμό token. Μετά την αποδέσμευση, ο λογαριασμός μπορεί και πάλι να στέλνει και να λαμβάνει tokens κανονικά. Μόνο η αρχή παγώματος του mint του token μπορεί να αποδεσμεύσει λογαριασμούς.

Το Token Program και το Token Extension Program έχουν παρόμοιες υλοποιήσεις για να επιτύχουν την ίδια λειτουργικότητα.
