Descongelar cuenta

¿Qué Hace Descongelar una Cuenta de Tokens?

Descongelar cambia una cuenta de tokens del estado congelado de vuelta al estado inicializado.

Después de que la descongelación tiene éxito, la cuenta puede transferir, quemar y cerrar tokens nuevamente. Solo la autoridad de congelación del mint puede descongelar cuentas de tokens.

Cómo Descongelar una Cuenta de Tokens

Descongelar una cuenta de tokens utiliza la instrucción ThawAccount del Token Program.

La instrucción ThawAccount verifica que la cuenta de tokens pertenezca al mint y que el firmante sea la autoridad de congelación del mint, luego cambia el estado de la cuenta de tokens de congelado de vuelta a inicializado.

Las cuentas de tokens nativas no admiten descongelación.
