Upgradeability Pattern Audits

Upgradeability pattern audits are specialized security reviews focused on smart contracts designed to be modified after deployment. In blockchain systems, code is typically immutable, but protocols often require updates to fix bugs or add features.

These audits verify that the proxy contracts, which delegate calls to implementation contracts, correctly manage state and logic transitions. Auditors ensure that the storage layout remains consistent across upgrades to prevent data corruption.

They also scrutinize the governance mechanisms that authorize these upgrades to ensure they cannot be hijacked. The goal is to confirm that the separation between the proxy and the logic contract is technically sound and secure against unauthorized changes.

These audits are critical in decentralized finance to protect user funds during protocol evolution.
