## Codebase Upgradeability Controls

Codebase Upgradeability Controls refer to the mechanisms that allow a protocol to update its code after deployment, such as proxy patterns or timelocks. These controls are essential for fixing bugs or adding features, but they also introduce a significant risk: if the upgrade mechanism is compromised, an attacker could replace the entire protocol logic with malicious code.

Therefore, robust controls require multi-signature wallets, lengthy timelocks, and community approval processes to prevent unauthorized changes. High-quality protocols implement strict governance requirements for any upgrade, ensuring that users have time to exit their positions if they disagree with the changes.

Assessing these controls involves examining the admin rights and the complexity of the upgrade path. Proper implementation balances the need for agility with the absolute requirement for immutable security in decentralized finance.
