Risk first: Funding rate arbitrage is not risk-free. Rates flip, shorts can liquidate on violent pumps, and fees or slippage can erase the edge. This page is informational only, may include referral links, and is not financial advice.
If you are searching for the best DEX for funding rate arbitrage, you already know the core idea: stay roughly delta-neutral and collect funding. The venue question is different — which book, fee schedule and margin setup keep a thin edge alive after rebalances. This page routes that choice between Hyperliquid and Aster. For the strategy math itself, start with funding rate arbitrage.
The best funding-arb DEX is the one that matches your hedge structure and keeps all-in cost below the funding you actually collect.
| Arb need | Hyperliquid | Aster |
|---|---|---|
| Classic spot + perp short | Strong default on liquid crypto | Possible where spot + perps both exist; verify markets |
| Fee drag on rebalance | Competitive base + referral / stake discounts | 0% maker path when you can post liquidity |
| Depth on majors | Usually preferred for BTC / ETH / SOL size | Check live book; broader catalog elsewhere |
| Carry beyond funding | Focus on funding + fee stack | Collateral / USDF-style yield can stack (verify live) |
| Broader markets | Crypto-first; HIP-3 exceptions | Often wider stocks / FX / metals catalog |

Product context side-by-side: Hyperliquid vs Aster. If your search is really “cheapest fees” rather than funding structure, use best perp DEX for zero fees instead.
Choose Hyperliquid when the trade is buy spot / short perp on the same account in liquid crypto. Fewer moving parts means fewer missed hedges when price jumps. Depth also matters: a cheap fee on a thin book is still a bad arb if one leg slips.

Choose Aster when you can enter or rebalance with maker/limit orders on markets where the 0% maker schedule applies, or when you want to research stacking funding with yield-bearing collateral. Thin weekly funding edges die first on taker fees — maker-zero is the point of the Aster path, not a promise that every fill is free.
Also prefer Aster as a research start when your funding idea sits on markets Hyperliquid does not cover well (selected stocks, FX, metals). Those contracts are still synthetics with their own funding and weekend behavior — see best DEX for gold and stocks before treating them like cash-and-carry on equities.

When funding differs between venues, the trade is short the expensive funding side and long the cheap side. There is no single “best” DEX — you need accounts ready on both. That is why serious operators keep Hyperliquid and Aster funded, then size only when the spread after fees still looks positive.
Checklist for spreads:
Lighter still appears in many low-fee and arb discussions. Zero or near-zero fee schedules can look attractive when edges are tiny. On this site it is an information reference, not the primary conversion recommendation — commercial focus stays on Hyperliquid and Aster. If you research Lighter, verify live fees, points and market depth yourself.
Same-account crypto carry with depth: open Hyperliquid through the referral link. Maker-sensitive or broader-market carry: open Aster and post small limits first. Either way, measure funding collected minus all-in cost — not the slogan.
