Zamrożenie konta

Co oznacza zamrożenie konta tokenów?

Zamrożenie konta tokenów zachowuje tego samego właściciela, mint i saldo, ale uniemożliwia kontu tokenów transferowanie lub spalanie tokenów do czasu odblokowania konta.

Zamrożone konto może nadal zostać zamknięte, jeśli zamrożone konto ma zerowe saldo tokenów.

Tylko mint, który nadal posiada uprawnienie do zamrażania, może zamrażać konta tokenów. Jeśli uprawnienie do zamrażania minta zostanie odwołane, konta dla tego minta nie mogą być już zamrażane.

Jak zamrozić konto tokenów

Zamrażanie konta tokenów wykorzystuje instrukcję FreezeAccount Token Program.

Instrukcja FreezeAccount weryfikuje, czy konto tokenów należy do minta oraz czy sygnatariusz jest uprawniony do zamrażania minta, a następnie zmienia stan konta tokenów z zainicjalizowanego na zamrożony.

Natywne konta tokenów nie obsługują zamrażania.
