Access control is a fundamental and persistent security concern in Ethereum smart contracts. Role-based access control (RBAC) systems grant privileged accounts the ability to perform sensitive operations such as pausing contracts, upgrading implementations, and modifying configurations. When an attacker compromises a privileged role key, they can immediately execute devastating operations with no intervention window. This immediate-execution model leaves protocols with no time to detect the compromise, coordinate a response, or prevent the damage.
In each case, a compromised key enables instant, irreversible damage. Traditional institutional security models require time-delayed authorization for high-privilege operations precisely to address this class of risk, yet no standardized on-chain mechanism exists for enforcing such delays at the role level.
This proposal provides a composable interface standard that introduces per-role execution delays into smart contract access control. By requiring that sensitive operations be scheduled before execution, the interface creates an on-chain audit trail and a mandatory delay window. During this window, monitoring systems can detect anomalous scheduling events, defenders can cancel or freeze suspicious operations, and protocols can respond before damage occurs.
