Overview
How Perps Arena compares perp DEX execution costs
Perps Arena pulls top-of-book quotes, simulates impact for the chosen notional, adds the venue’s posted fee schedule, and overlays current funding.
The cheapest headline fee isn’t always the cheapest total — funding and slippage can dominate at $500k+ size (per neuralarb.com 2026 analysis: “At $500K+ position size, Hyperliquid slippage (≈12 bps) begins to approach the funding spread itself”).
