تعيين الصلاحية

ما الذي يفعله تعيين الصلاحية؟

يقوم تعيين الصلاحية بتغيير أو إلغاء أدوار صلاحيات محددة على mint account أو token account.

يمكن لحسابات السك تخزين صلاحية السك وصلاحية التجميد. تخزن حسابات الرموز المالك ويمكنها اختيارياً تخزين صلاحية الإغلاق. كل دور يتحكم في مجموعة أذونات محددة، وتعيين الصلاحية إلى None يزيل بشكل دائم دور الصلاحية المحدد.

يحدد Token Extensions Program أيضاً أنواع صلاحيات إضافية لملحقات محددة.

كيفية تعيين الصلاحية

يستخدم تغيير الصلاحية تعليمة SetAuthority من Token Program.

كل استدعاء يحدث نوع صلاحية واحدة على mint account أو token account واحد. توقع الصلاحية الحالية التغيير، وقد تكون الصلاحية الجديدة عنوان آخر أو None لإلغاء الصلاحية المحددة بشكل دائم.
