proxy-upgrade-safety

v1.0.0

Detects vulnerabilities in upgradeable proxy smart contracts — storage layout collisions, uninitialized implementations, function selector clashing, and upgrade path safety issues. Covers Transparent, UUPS, Beacon, Diamond (EIP-2535), and Minimal proxy patterns. Critical for the 54.2% of Ethereum contracts that use proxy architecture.
