1inch vs ParaSwap
Neutral on-chain benchmarking of slippage, revert rates, and overall execution quality.
Protocol Scorecard
1inch and ParaSwap 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 a slippage score of 92.5/100 versus 76.7/100 for ParaSwap — a clear edge of 15.8 points. The score reflects realized slippage only — derived from median slippage versus a 1-minute VWAP, where a higher number means lower slippage. MEV exposure and revert rates are tracked as separate metrics. 1inch was measured over 18,988 trades and ParaSwap over 10,956.
On this data, 1inch holds the stronger slippage score, but the gap reflects routing and slippage differences rather than one venue being universally better — results shift with trade size, token pair, and market conditions, and MEV exposure and revert rates are separate considerations. Scores update on each data refresh; see our methodology for the full approach.
Frequently Asked Questions
Which has better execution quality, 1inch or ParaSwap?
Based on ClearTrace's slippage score (median slippage vs a VWAP baseline), 1inch edges out ParaSwap, 92.5/100 versus 76.7/100 (a 15.8-point gap).
Does 1inch or ParaSwap offer better MEV protection?
ClearTrace publishes a slippage-based score and per-aggregator revert rates — not a per-aggregator MEV-protection score. On slippage, 1inch was tighter (~7.5 bps vs ~23.3 bps). For MEV specifically, the dashboard surfaces detected sandwich activity as a separate metric.
Is 1inch or ParaSwap better for large trades?
For large orders, aggregators such as 1inch 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.
