## Access Control List

An access control list is a list of permissions attached to a smart contract or system function that defines which addresses or roles can perform specific actions. It is a core component of security architecture, ensuring that sensitive functions like minting tokens or updating protocol parameters are restricted.

By implementing granular roles, developers can follow the principle of least privilege, minimizing the damage if a specific account is compromised. This is critical for preventing unauthorized changes to the protocol's state.

As protocols grow in complexity, managing these lists becomes increasingly important for maintaining long-term security. It serves as the digital gatekeeper for protocol administration.
