Top Perp DEXs by Funding APR — The Short Answer
By open interest and liquidity, Hyperliquid is the #1 perpetual DEX in 2026, followed by a cluster of order-book DEXs like Aster, Lighter, edgeX and Paradex. But "best" for funding-rate farming isn't just about size — the venue with the widest, most persistent funding rate spread against a liquid counter-leg is where the real yield lives. The live table below ranks them.

The ranking above updates automatically from our database — open interest (OI), 24h volume, maker/taker fees and current funding are pulled live, so what you see is current, not a snapshot frozen into this article. Below we break down the notable venues, what funding APR actually means on a DEX, and how to read the list without getting faked out by mirrors and TradFi namespaces.
How to Read This Ranking
Three columns matter most for a funding farmer:
- Open Interest (OI): total dollar value of open positions. High OI means you can enter and exit size without moving the mark. It's the single best proxy for whether a DEX is "real."
- 24h Volume: turnover. High volume with low OI can signal churn or wash activity; high OI with steady volume signals genuine depth.
- Funding APR: the annualized funding rate. Positive means longs pay shorts; negative means shorts pay longs. This is the yield you harvest in a delta-neutral position.
A big number in the funding column on a thin, low-OI venue is usually a trap — the rate is extreme because nobody is arbitraging it, and you often can't get filled at that rate. Cross-reference OI before you get excited. Our funding screener shows the same asset across every exchange side by side so you can spot which leg is the outlier.
Hyperliquid — The Liquidity Benchmark
Hyperliquid is the default #1 by OI and volume, and for good reason: a fully on-chain order book with CEX-grade latency, deep books on majors, and 1-hour funding intervals. For funding farmers it's usually the anchor leg — the liquid, trustworthy side you pair against a higher-funding venue elsewhere.
Pros: deepest DEX liquidity, tight spreads, reliable funding, huge asset coverage. Cons: because it's so heavily arbitraged, its standalone funding rarely reaches the extremes you'll see on newer venues. The edge is in the spread to another exchange, not Hyperliquid alone.
Bullpen — A Hyperliquid Mirror (Read This Honestly)
Bullpen appears in DEX lists and screeners, but it is a mirror of Hyperliquid — "Powered by HL." It routes to Hyperliquid's liquidity rather than running its own independent order book. That means the funding spread between Bullpen and Hyperliquid is effectively zero — they're the same underlying market. Do not treat a Bullpen↔Hyperliquid "spread" as an arbitrage; there isn't one. Bullpen can still be a fine front-end to trade on (points, UX), but for delta-neutral funding farming, pair it against a genuinely independent venue, never against its parent.
Aster, Lighter, edgeX & the Independent Order-Book DEXs
Below Hyperliquid sit the independent CLOB DEXs — Aster, Lighter, edgeX (V2 runs USDC-margined), Paradex, GRVT and others. These matter for funding farming precisely because their books are separate from Hyperliquid's, so their funding rates drift independently. When a memecoin or mid-cap pumps, one of these venues will frequently run a much richer funding rate than the majors, opening a real spread.
Pros: independent price discovery, frequently the higher-funding leg, active points programs. Cons: shallower books than Hyperliquid — always check that OI supports your size, and model slippage before assuming the spread is capturable.
A Note on trade[XYZ] and TradFi Namespaces
Some Hyperliquid-ecosystem namespaces (like trade[XYZ]) are TradFi-stock venues — they list tokenized equities, commodities and forex, not general crypto perps. If you see "BTC" appearing on such a venue in a raw feed it's almost always a mirror artifact, not a tradable crypto book on that venue. Treat these as a separate asset class; they belong in a stocks/RWA screener, not your crypto funding-arb shortlist.
What Funding APR Means on a DEX (and How to Farm the Spread)
Perpetual futures have no expiry, so an exchange uses funding payments to tether the perp price to spot. Every interval (1h on most DEXs, 8h on some CEXs), the side on the "expensive" end of the market pays the other side. Annualize that periodic rate and you get funding APR.
The strategy is delta-neutral: go long on the venue that pays longs (negative funding) and short on the venue where shorts get paid (high positive funding) for the same asset. Your net market exposure is ~zero, and you collect the funding spread between the two legs. Combined APR on our screener also folds in estimated points value, since many DEXs reward volume with pre-token points — use the points calculator to convert points into an expected dollar yield.
The catch is cost. A 40% funding spread that gets eaten by 0.6% round-trip slippage plus taker fees on entry and exit isn't a 40% trade. Run any pairing through the backtester first — it subtracts real orderbook slippage and actual taker fees from historical funding, so you see the net APR you'd actually have earned, not a gross fantasy number.
How We Rank / Methodology
The live table ranks perp DEXs primarily by open interest, our most reliable proxy for genuine liquidity, with 24h volume and current funding shown alongside. All figures are read at render time from our aggregator, which ingests funding, mark price and order books across 38 exchanges through per-market verified funding intervals (we never hardcode 8h — a wrong interval silently doubles or halves APR).
We flag mirrors (like Bullpen→Hyperliquid) so you don't chase phantom spreads, exclude dead or single-namespace TradFi venues from crypto rankings, and apply liquidity floors so a $10k-OI ghost market with a 3000% "funding rate" can't top the list. Funding rates are shown in the exchange's native sign convention (positive = longs pay shorts) and annualized using each market's true interval. Where a venue lacks a public funding history we build it organically from live ingestion rather than guessing.
