CoWSwap vs Uniswap
Neutral on-chain benchmarking of execution quality, MEV protection, and overall trade execution.
Protocol Scorecard
CoWSwap is a DEX aggregator that routes and splits orders across many venues, while Uniswap is a single automated market maker (AMM) trading against its own pools. The practical question is whether CoWSwap's routing and MEV-aware order flow actually beats trading directly on Uniswap. Note that CoWSwap can itself route through Uniswap pools, so this measures the value of aggregation, not rival liquidity.
Across the trades ClearTrace benchmarked, Uniswap posted an execution-quality score of 87.5/100 versus 84.7/100 for CoWSwap — a meaningful but not decisive edge of 2.8 points. The score blends realized slippage with an MEV/toxicity measure, so a higher number means traders kept more of their expected value. Uniswap was measured over 1,402,918 trades and CoWSwap over 14,604.
The sample sizes differ substantially (Uniswap: 1,402,918 trades; CoWSwap: 14,604), so CoWSwap's score reflects a narrower slice of activity and may move as more volume is observed.
On this data, Uniswap holds the stronger execution-quality score, but the gap reflects routing and MEV protection rather than one venue being universally better — results shift with trade size, token pair, and market conditions. We recalculate these scores on every data refresh; see our methodology for the full approach.
Frequently Asked Questions
Which has better execution quality, CoWSwap or Uniswap?
Based on ClearTrace's on-chain benchmarking, Uniswap edges out CoWSwap on execution quality, 87.5/100 versus 84.7/100 (a 2.8-point gap).
Does CoWSwap or Uniswap offer better MEV protection?
MEV protection is captured by our toxicity measure, where lower is better. CoWSwap scored a toxicity of 15.3 and Uniswap 12.5, so Uniswap showed somewhat stronger protection against value extraction such as sandwich attacks over the sample.
Is CoWSwap or Uniswap better for large trades?
For large orders, aggregators such as CoWSwap can split a trade across multiple pools to reduce price impact, which often helps on size. The right venue still depends on the specific pair and amount — the live dashboard tracks current execution quality.
