Account ontdooien

Wat Doet Het Ontdooien van een Token Account?

Ontdooien verandert een token account van de bevroren status terug naar de geïnitialiseerde status.

Nadat het ontdooien is geslaagd, kan het account opnieuw tokens overdragen, verbranden en sluiten. Alleen de freeze authority van de mint kan token accounts ontdooien.

Hoe Een Token Account Te Ontdooien

Het ontdooien van een token account gebruikt de ThawAccount instructie van het Token Program.

De ThawAccount instructie verifieert dat het token account bij de mint hoort en dat de ondertekenaar de freeze authority van de mint is, waarna de status van het token account wordt veranderd van bevroren terug naar geïnitialiseerd.

Native token accounts ondersteunen geen ontdooien.
