Définir l'autorité

Que fait la définition d'autorité ?

La définition d'autorité modifie ou révoque des rôles d'autorité spécifiques sur un mint account ou un token account.

Les mint accounts peuvent stocker une autorité de mint et une autorité de gel. Les token accounts stockent un propriétaire et peuvent éventuellement stocker une autorité de fermeture. Chaque rôle contrôle un ensemble de permissions spécifiques, et définir une autorité sur None supprime définitivement le rôle d'autorité sélectionné.

Le Token Extensions Program définit également des types d'autorité supplémentaires pour des extensions spécifiques.

Comment définir une autorité

La modification d'une autorité utilise l'instruction SetAuthority du Token Program.

Chaque appel met à jour un type d'autorité sur un mint account ou un token account. L'autorité actuelle signe la modification, et la nouvelle autorité peut être une autre adresse ou None pour révoquer définitivement l'autorité sélectionnée.
