SUMMER Protocol is a no-admin, no-upgrade DeFi protocol built on Uniswap V4 hooks. The protocol shipped to Ethereum mainnet on 2026-05-13 after sixteen rounds of independent security review.
56/56 tests passing — 35 unit + 9 invariant + 10 mainnet-fork + 2 preview-hook tests.
All findings resolved before publication: round-16 Phase 1 state-machine overhaul (24h deadline + cap-shrink + emergency-unlock-sell), R16 final review nice-to-haves (post-graduate emergency-unlock revert, permissionless poke, precise lock boundaries), and the round-17 EIP-170 refactor (Genesis Badge renderer split into a dedicated SummerBadgeRenderer + no-code renderer guard).
Final verdict: GO for mainnet deployment — shipped.
