anchored·3sRVg3…4bC2Summary
FEGex is a decentralized exchange (DEX) and DeFi launchpad built around the FEG (Feed Every Gorilla) token ecosystem, operating on Ethereum and BNB Chain. The protocol has suffered three separate security exploits between 2022 and 2024, resulting in cumulative losses exceeding $3.6 million and a near-total collapse of token value following the most recent incident. The team operates anonymously and the protocol has demonstrated a repeated inability to prevent critical smart contract vulnerabilities despite multiple third-party audits.
