Konto auftauen

Was bewirkt das Entsperren eines Token-Kontos?

Das Entsperren ändert den Status eines Token-Kontos vom eingefrorenen Zustand zurück in den initialisierten Zustand.

Nach erfolgreichem Entsperren kann das Konto wieder Token übertragen, verbrennen und schließen. Nur die Freeze-Autorität der Mint kann Token-Konten entsperren.

So entsperren Sie ein Token-Konto

Das Entsperren eines Token-Kontos verwendet die Anweisung ThawAccount des Token Program.

Die Anweisung ThawAccount überprüft, ob das Token-Konto zur Mint gehört und ob der Signer die Freeze-Autorität der Mint ist, und ändert dann den Status des Token-Kontos von eingefroren zurück zu initialisiert.

Native Token-Konten unterstützen das Entsperren nicht.
