Hyperliquid vs Paradex vs Lighter — The Board's Verdict
// Comparison posts on other sites are PR. This one is scraped. Three perp DEXes, three use cases, one verdict — pulled from the Forge's own stored funding data and live open interest.
Comparison posts on other sites are PR. Every top-10 DEX roundup you've scrolled this year was written from press kits, screenshotted fee tables, and the venue's own pitch deck. This one is scraped. The Forge has been polling Hyperliquid, Paradex, and Lighter on a ten-second pulse for the last three days and storing every funding rate, every mark price, every open interest snapshot. The numbers below come from that database, not from anyone's marketing site.
Three contenders. Three use cases. One verdict per use case, committed — not hedged.
// THE CONTENDERS
Hyperliquid — L1 perp DEX on its own chain. Largest open interest on the board by a factor of fifteen over the next venue. Hourly funding settlements. Battle-tested book. The default answer to "which DEX for perps" if you haven't picked a side yet.
Paradex — StarkWare L2, institutional lean. 8-hour funding intervals. Tightest taker fee of the three at 3.0 bps. Thinner on BTC and ETH than either of the other two venues, which matters when it's time to size up.
Lighter — zk-rollup-backed, relatively newer entrant. Zero taker and maker fees as a selling point. 1-hour funding, same cadence as Hyperliquid. Thin books at the long-tail end of the listings; pricing advantage shows up on entry.
// FEES — THE ENTRY TAX
Actual per-venue fees from the Forge's cost schedule, transcribed from backend/services/costs.py:
| Venue | Taker bps | Maker bps | Slippage bps | Round-trip single-leg (entry + exit + slip) | |-------------|-----------|-----------|--------------|---------------------------------------------| | Hyperliquid | 3.5 | 1.0 | 3 | 10 bps | | Paradex | 3.0 | 0.5 | 5 | 11 bps | | Lighter | 0 | 0 | 6 | 6 bps |
On a $10,000 trade, that single-leg round-trip cost is ten dollars on Hyperliquid, eleven on Paradex, six on Lighter. A delta-neutral pair uses two venues — so the total round-trip bill on a pair is the sum of both legs' single-leg costs. An HL-Lighter pair costs 16 bps round trip. HL-Paradex costs 21 bps. Paradex-Lighter costs 17 bps.
Lighter's "zero fees" pitch is not a gift. The books are thin enough that 6 bps of slippage eats more than the 3.5 bps taker on Hyperliquid costs you. The advantage is real but modest — three or four bps, not the zero the marketing copy suggests. Read the slippage column. It is the fee.
// OPEN THE COST LEDGER
// FUNDING INTERVALS — WHY THEY MATTER
Hyperliquid and Lighter pay hourly. Paradex pays every 8 hours. This is not a cosmetic difference — it changes which strategies fit each venue.
For fast-moving spreads, hourly wins. If a spread opens at 3 AM and closes at 6 AM, an hourly venue pays you at 4 AM and 5 AM; an 8-hour venue pays you nothing unless you're still holding at the next 00/08/16 UTC boundary. Short-hold funding arb on Paradex is a timing lottery you usually lose.
For set-and-hold carry, the interval barely matters. Collect the funding over a week or a month and the per-settlement cadence averages out. Paradex's 8-hour cycle is stable, predictable, and institutional-friendly. Nobody running a $500k delta-neutral pair across two weeks cares whether settlements hit every hour or every eight.
Pick the interval that matches the hold. Don't try to day-trade an 8-hour venue.
// THE FUNDING BEHAVIOR — THE ACTUAL DATA
The Forge's database currently holds 72 hours of funding history — retention capped at three days, scraping since 2026-04-17 04:25 UTC. Everything in this section scopes to that window. No 30-day claims, no invented depth. Sample counts sit around 18,000 per venue per symbol — a one-every-fifteen-seconds pulse.
BTC across the past 3 days:
| Venue | Mean APR (BTC) | Funding/hr stdev | Min/hr | Max/hr | |-------------|----------------|------------------|----------|----------| | Hyperliquid | −7.31% | 0.00088% | −0.00989%| +0.00125%| | Paradex | +0.38% | 0.00122% | −0.00301%| +0.00125%| | Lighter | −3.57% | 0.00133% | −0.00620%| +0.00120%|
ETH across the past 3 days:
| Venue | Mean APR (ETH) | Funding/hr stdev | Min/hr | Max/hr | |-------------|----------------|------------------|----------|----------| | Hyperliquid | −13.75% | 0.00093% | −0.00970%| +0.00125%| | Paradex | −10.47% | 0.00172% | −0.00497%| +0.00114%| | Lighter | −2.84% | 0.00131% | −0.00480%| +0.00120%|
Read the signs. Negative funding means shorts are paying longs. Across all three venues and both majors, funding has leaned negative for seventy-two hours straight — the market is crowded short on perps, and longs are collecting. Hyperliquid leans hardest negative on ETH at nearly −14% APR, which is a directional signal independent of any arb play.
Now read the spread between the columns. On ETH, Hyperliquid is at −13.75% and Lighter is at −2.84% over the same three days. That's a ~10.9 percentage-point funding gap, averaged across the window. A trader who shorted ETH on Lighter and longed ETH on Hyperliquid during that window would have collected roughly 10.9% APR gross on a delta-neutral pair, before fees. Net of the 16 bps HL-Lighter round-trip cost amortised over a 7-day hold, that's ~2.5% net APR — thin but real.
Paradex stdev is higher than both Hyperliquid and Lighter on ETH (0.00172 vs 0.00093 and 0.00131). Higher volatility of funding means the spread you entered is less likely to hold steady across your hold window. For a risk-matched backtest, Paradex is noisier.
// LIQUIDITY — WHERE YOU CAN SIZE UP
Current open interest (live from /api/funding-rates at write time):
| Venue | BTC OI (USD) | ETH OI (USD) | Total book OI (USD) | |-------------|--------------|--------------|---------------------| | Hyperliquid | $2.0B | $1.0B | $5.4B | | Lighter | $123M | $75M | $359M | | Paradex | $10M | $4M | $35M |
Hyperliquid is dominant. Not slightly dominant — fifteen times the next venue on aggregate OI, two hundred times Paradex on BTC specifically. If you want to place a $100k leg without eating visible slippage, Hyperliquid is the only one of these three where that's even a question.
Lighter is a real venue with real size. $123M of BTC open interest is enough to run serious delta-neutral pairs against Hyperliquid. The spread is the opportunity; the thin books are the friction.
Paradex on BTC and ETH is book-constrained. Ten million in open interest means a $50k order is 0.5% of the entire book. Funding arb on Paradex-majors is a small-size play. That doesn't make it useless — it makes it a different weight class.
// OPEN THE HEATMAP
// VERDICT
Three use cases. One pick each. No diplomatic hedging.
If the play is hunting fast spreads on majors: Hyperliquid. Tightest effective books, fastest funding cadence, deepest OI by an order of magnitude. Every arb scanner — including this one — centers on Hyperliquid because that's where the volume decides what "fair" looks like. Lowest friction for entry, lowest friction for exit, most history for the backtest to use.
If the play is slower institutional-grade carry: Paradex. 8-hour settlements are a feature, not a bug, for the trader holding two weeks. The 3.0 bps taker is the cheapest of the three on paper. The thin BTC and ETH books cap position size at the tens of thousands — but at that size, the 8-hour cadence pays out cleanly and the operational overhead is low.
If the play is hunting pricing inefficiencies before the crowd arrives: Lighter. Newer, thinner, less efficient. The funding rates diverge from Hyperliquid more often than they should — which is exactly where funding arb edge lives. Zero fees get eaten by 6 bps slippage on thin books, but that's still cheaper round-trip than the other two. Best venue to pair with Hyperliquid for delta-neutral plays right now.
These are not permanent rankings. Venues change. Hyperliquid could freeze. Paradex could ship an L3 upgrade that doubles their books. Lighter could get exploited and lose the trust premium that justifies the thin-book friction. The Forge re-ranks every ten seconds. These picks are for the quarter, not forever.
// WHAT THE BOARD LETS YOU DO
All three venues ship on the heatmap side by side. Every cell is a live funding rate. Click any cell and the strategy modal opens for that symbol with every venue's leg pre-loaded — the modal picks the best long and best short automatically. Read the cost waterfall before sizing. Run the backtest against the history the DB has retained. Do not ape on a screenshot.
The board is the scanner. The heatmap is the spread atlas. The backtest is the paper trial. Every play worth running starts with one of those three tools.
// SCAN THE BOARD // RUN A BACKTEST// THE CLOSING DISPATCH
The comparison posts that other sites publish are paid advertising with a comparison chart on top. This dispatch is the opposite — three days of scraped data, live open interest, the actual fee schedule the Forge uses to compute net APR. Every number in it can be re-queried from the same database that feeds the dashboard. The data is the proof.
Hyperliquid for speed. Paradex for cadence. Lighter for pricing. Mix them. Pair them. Run the play.
