Summary
GoonFi is a proprietary automated market maker (Prop AMM) operating on Solana, launched in June 2025 with no public team, no frontend, and no published smart-contract audit. On March 28, 2026, a protocol logic vulnerability was exploited via mispricing arbitrage, resulting in approximately $254,000 in losses with no recovery reported. The protocol has been flagged by ZachXBT and is cited by researchers as representative of a broader Solana centralization concern, wherein anonymous, closed-source market makers capture an outsized share of DEX volume with minimal accountability.
