0x vs 1inch
Neutral on-chain benchmarking of execution quality, MEV protection, and overall trade execution.
Protocol Scorecard
0x and 1inch are both DEX aggregators: rather than holding liquidity themselves, they split each order across many underlying pools to find the best available price. Because both compete on routing quality, the difference between them shows up in execution — realized slippage and MEV exposure — far more than in their headline rates.
Across the trades ClearTrace benchmarked, 1inch posted an execution-quality score of 92.2/100 versus 91.0/100 for 0x — a statistical dead heat of 1.2 points. The score blends realized slippage with an MEV/toxicity measure, so a higher number means traders kept more of their expected value. 1inch was measured over 17,835 trades and 0x over 53,903.
On current data the two are effectively tied — within measurement noise, either is a reasonable choice, and the better option often comes down to the specific token pair and trade size. We recalculate these scores on every data refresh; see our methodology for how they are derived.
Frequently Asked Questions
Which has better execution quality, 0x or 1inch?
They are essentially tied. 0x scored 91.0/100 and 1inch 92.2/100 in ClearTrace's on-chain benchmarking — a difference within measurement noise.
Does 0x or 1inch offer better MEV protection?
MEV protection is captured by our toxicity measure, where lower is better. 0x scored a toxicity of 9.0 and 1inch 7.8, so 1inch showed somewhat stronger protection against value extraction such as sandwich attacks over the sample.
Is 0x or 1inch better for large trades?
For large orders, aggregators such as 0x 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.
