AccessControlComponent
AccessControl Component
The AccessControl component enables role-based access control mechanisms. This is a lightweight implementation that doesn’t support on-chain enumeration of role members, though role membership can be tracked off-chain through contract events.
Roles can be granted and revoked dynamically via grant_role and revoke_role. Each role
has an associated admin role that controls who can grant and revoke it. By default, all roles
use DEFAULT_ADMIN_ROLE as their admin role.
Accounts can also renounce roles they have been granted by using renounce_role.
More complex role hierarchies can be created using set_role_admin.
WARNING: The DEFAULT_ADMIN_ROLE is its own admin, meaning it can grant and revoke itself.
Extra precautions should be taken to secure accounts with this role.
