## Vulnerability Patching Lifecycle

The vulnerability patching lifecycle is the systematic process of identifying, evaluating, testing, and remediating security flaws within smart contracts or protocol infrastructure. In the context of decentralized finance and digital assets, this lifecycle is critical because code is immutable once deployed, making post-deployment fixes complex.

The process begins with discovery, where security researchers or automated tools identify potential exploits. Once a vulnerability is confirmed, developers assess the severity and potential impact on protocol liquidity and user funds.

The team then develops a patch, which must undergo rigorous testing in a sandboxed environment to ensure it does not introduce new bugs. Finally, the patch is deployed through a governance vote or an emergency multi-signature wallet, followed by post-patch monitoring to ensure system stability.
