## Access Control Review

Access control review is the process of auditing the permissions and authorization mechanisms within a smart contract to ensure that only authorized users or addresses can perform sensitive actions. This includes managing administrative roles, ownership transfers, and privilege levels for functions like minting tokens, pausing contracts, or upgrading code.

In financial protocols, weak access control can lead to catastrophic losses if an attacker gains control over core functions. The review ensures that the principle of least privilege is applied, minimizing the impact if an account is compromised.

It involves checking that access modifiers are correctly implemented and that multi-signature requirements are enforced for high-value operations. Proper access management is a cornerstone of decentralized security.
