Cheapest perp DEX for ETH

As of October 6, 2026, Lighter leads ETH all-in cost at 0.0025% (p50, 24h window), measured across 11 providers.

The cheapest perp DEX for ETH on this benchmark sits at 0.0025% all-in (p50, 24h) for a $1000 ETH long 10x. ETH-PERP is the deepest pair on every venue measured (Hyperliquid, Lighter, Polymarket, Paradex, Extended, dYdX v4, GMX v2, Gains), which means the rack-rate taker fee dominates the all-in number rather than the spread. Lighter quotes 0 bps taker, Hyperliquid 4.5 bps, dYdX 5 bps tier-0, GMX 4 or 6 bps on the impact branch, Gains reads the openFeeP slot live from the on-chain Gains v8 fees contract. Spread plus impact at $1000 notional is added on top via an orderbook walk.
