Beating the Uniswap default isn't automatic

ClearTrace measures each aggregator's median on-chain execution cost over every trade it routes, and benchmarks it against the Uniswap direct-DEX baseline — the cost of just swapping straight through Uniswap. This period the baseline sat at 10.75 bps. Only one aggregator meaningfully undercut it at scale: 1inch, at 5.49 bps across 15,334 trades — roughly 5 bps cheaper than the default.

Several routers came in more expensive than the default: KyberSwap at 13.48 bps (15,262 trades), Paraswap 14.36 bps (4,165), Sushi 25.86 bps (1,169). Odos essentially tied the baseline at 10.42 bps. These are observed medians and partly reflect each router's trade mix — a router carrying more thin-liquidity pairs will look costlier — but the takeaway holds: the aggregator premium isn't guaranteed, and it's worth checking rather than assuming.

This period in numbers

Aggregator quotes are landing within a basis point

Among rated cells, the median gap between the quoted price and what actually filled is 0.0 bps for 1inch (1,482 realized samples) and the Uniswap baseline (1,535), 1.0 bps for Paraswap (1,467), and 2.61 bps for KyberSwap (1,424).

KyberSwap fills 86% of its $1M flow off-chain

At the $1M trade size, 86.3% of KyberSwap's sampled flow settles through off-chain RFQ rather than on-chain AMMs — by far the heaviest RFQ reliance of any rated router in the cohort. Source: aggregator leaderboard (rfq_share_1m), generated 2026-07-09.

Revert rates: batch settlement stays near zero

CoW Protocol reverted on just 0.04% of 12,217 trades this period; Paraswap 1.57% (4,165) and 1inch 1.45% (15,334) also stayed low. Source: on-chain revert tracking (onchain_revert_rate_pct), 2026-07-09.

144 rated quote cells, 92.4% attribution coverage

The sampler has now taken 10,586 fork-simulated quote samples over 16.4 days (90% realized), of which 144 cells have cleared the rated bar (≥30 realized samples, ≥7-day span). Cross-chain attribution coverage sits at 92.4% (Ethereum 94.4%, Arbitrum 88.4%, Base 88.2%, Optimism 86.7%). Source: quote sampler report + dune_attribution, synced 2026-07-08.

Methodology

ClearTrace · Cross-chain DEX attribution · Data as of 2026-07-09 (quote sampler) / 2026-07-08 (on-chain attribution).
Execution cost and revert rate are on-chain medians over all trades; the Uniswap baseline is the direct-DEX median that aggregators are compared against. Quote-gap figures are rated (≥30 fork-simulated realized samples, ≥7-day span) unless noted.
Figures are sourced from on-chain trace data and the ClearTrace live quote sampler — no protocol claims are fabricated.
