Malicious Upgrade Prevention

Malicious upgrade prevention encompasses all the technical and social strategies used to ensure that only safe, approved code is deployed to a protocol. This includes the use of timelocks, multisig governance, and mandatory security audits.

It also involves technical constraints on what can be upgraded and who has the authority to propose changes. By creating a layered defense, protocols can effectively neutralize the threat of a rogue developer or a compromised admin key.

Preventing malicious upgrades is the single most important task for maintaining the integrity of an upgradeable smart contract system. It requires constant vigilance and robust security engineering.
