Signature

IB20.sol

​
Description

Revokes role from account and emits RoleRevoked(role, account, sender). B20 follows OpenZeppelin AccessControl semantics, under which revoking a role the account does not hold changes nothing and emits no event.

​
Parameters

​
Reverts

  • AccessControlUnauthorizedAccount: caller does not hold the admin role for role, or the token has no admins (transitioned via renounceLastAdmin).
  • LastAdminCannotRenounce: role == DEFAULT_ADMIN_ROLE and account is the last remaining DEFAULT_ADMIN_ROLE holder. Use renounceLastAdmin to clear the final admin intentionally.

​
Access Control

The caller must hold getRoleAdmin(role). On a fresh token every role’s admin is DEFAULT_ADMIN_ROLE. After setRoleAdmin is called the new admin role applies; revokeRole is not hardcoded to DEFAULT_ADMIN_ROLE.

​
Policy Interaction

No direct policy interaction.
