The most consequential contract set in DeFi and among the most conservative. No admin key can move pooled funds, and the v2, v3 and v4 pools have held billions since 2020 without a protocol-layer exploit. Since the UNIfication vote of December 2025 a governance-set share of each pool fee goes to a UNI burn rather than to liquidity providers.
Best for: Pool contracts with no admin key over funds, at the largest scale
8.9 is the weighted average of the five pillar findings below. Does the job well with no material unresolved concerns.
Each version is a separate, non-upgradeable contract set with no admin authority over pooled funds; multiple independent audits. The one drained pool on record was a v1 pool hit by the imBTC reentrancy in April 2020. v4 pools are only as safe as the hook attached to them.
Fee tiers are explicit and set on-chain. Since the UNIfication vote of 26 Dec 2025 a protocol fee is on: 0.05% of the 0.30% on v2, 1/4 or 1/6 of the fee on v3, and v4 pools on seven networks since Jul 2026. The swapper pays the same; the LP keeps less.
Unlicensed by design. Governance sits in DUNI, a Wyoming DUNA adopted 9 Sep 2025. Uniswap Labs paid a $175,000 CFTC penalty in Sep 2024; the SEC closed its investigation with no action on 25 Feb 2025.
Held through every major market break of the period with no degradation in the core mechanism.
Extremely well documented with the largest integration surface in DeFi.
Strengths
Against it
Uniswap scores highest in this table for an unglamorous reason: no admin key can move pooled funds, each version is a separate contract set that nobody can upgrade, and the v2, v3 and v4 pools have held billions since 2020 without a protocol-layer exploit. Every part of that is checkable, which is what a documentary method can actually reward.
Two things changed the picture slightly. Since the UNIfication vote of 26 Dec 2025 a governance-set share of each pool fee goes to a UNI burn instead of to liquidity providers; the swapper pays the same, the LP keeps less. And v4 pools can carry hooks, external contracts that are only as safe as whoever deployed them. Neither has cost anyone a deposit so far.
Upgradeability and collateral. Aave’s contracts are upgradeable through governance, and in April 2026 unbacked rsETH accepted as collateral put about $193M of loans at risk. Uniswap pools have no upgrade path and no collateral to misprice; the worst a pool can do is trade against a bad token you chose to buy.
No. There is no admin key over pooled funds and the pool contracts cannot be changed. Governance can switch the protocol fee on or off per pool and spend the treasury; since December 2025 that fee is on for v2 and selected v3 pools on Ethereum and, since July 2026, for v4 pools on seven networks.
Your own transactions. Nobody can reverse a swap you signed, sandwich attacks and approval phishing are real, a token you buy can still be worthless, and a v4 pool is only as safe as its hook. The protocol layer is about as sound as evidence gets; the trading is not risk-free.
