## Upgradeability Proxy Security

Upgradeability proxy security refers to the architectural safeguards required to safely modify smart contracts after deployment. Since blockchains are immutable, developers use proxy patterns to separate contract logic from state storage.

A proxy contract holds the data and points to a logic contract, which can be swapped to upgrade features or fix bugs. The primary security risk is the storage collision, where a new logic contract accidentally overwrites the proxy state variables.

Another risk is the unauthorized upgrade, where a malicious actor gains control of the admin key to point the proxy to a fraudulent contract. Proper security involves using established patterns like EIP-1967, ensuring access control is decentralized, and implementing timelocks for upgrades.

These measures prevent catastrophic loss of funds in decentralized finance protocols.
