Above $50k, slippage and MEV dominate — pick accordingly.
On large trades, the gap between aggregators widens: routing depth determines slippage, and MEV protection determines whether bots skim your fill. Always pull quotes from two or three and compare the all-in output.
The strongest large-trade choice: batch auctions give uniform clearing prices and eliminate sandwich MEV.
Deep routing plus Fusion’s MEV-protected solver fills — pull a quote alongside CoW Swap.
Deep aggregated liquidity and the highest ETH aggregator share in 2026.
For trades above ~$50k, quote CoW Swap and 1inch (and KyberSwap), and take the best all-in output.
