Funding cost to hold a long 24h
Astern/aExtendedn/a

Funding is signed. Positive means longs pay shorts, negative means longs get paid to hold. Venues settle on different native periods (hourly on Hyperliquid, dYdX, Lighter, Extended, Pacifica, Ondo, Vest, StandX and ApeX, every 4h on edgeX, every 8h on Kalshi, Aster and the CEX books); every figure is normalized from the venue's own quoted rate and interval before ranking. Funding is only the holding cost. Opening costs (taker fee, spread, impact) are the companion bench perp-fees.

Astern/aExtendedn/a

Counts reflect each venue's live market catalog at query time, mainnet only. The asset class comes from the venue's own metadata where it publishes one; Hyperliquid HIP-3 dexes and dYdX publish none, so their symbols are matched against the crypto markets the other venues list and a fixed table of forex, commodity and index names. Tokenized gold (PAXG, XAUT) is a crypto token and is not counted. A market counts once whether it trades 24/7 or only during exchange hours.

Markets per $M TVL
Astern/aExtendedn/a

TVL from DefiLlama /protocol/{slug} currentChainTvls, excluding staking and pool2 categories. Market count from each venue's native API (same source as the perp-active-markets bench). The ratio reflects architectural choices, not absolute liquidity: a high ratio means the venue can list many markets cheaply, not that each market has deep liquidity. Compare with perp-volume-share for the liquidity angle.

Perp DEX price to fees: what the market pays per dollar of trading fees

P/F = circulating market cap (CoinGecko) / annualized fees (DeFiLlama dailyFees, trailing 30d x 365/30), on the DeFiLlama parent the token accrues from. Fees include the share paid to liquidity providers; P/S uses protocol revenue only. Low-float tokens show a much higher FDV/F than P/F. Pre-TGE venues are listed unranked with fees and OI, no ratio. A low multiple is not a recommendation.

Volume is self-reported by each venue's public data surface and counted per UTC day, one side of each trade. Perimeters differ slightly per venue and are stated in the ledger notes. A closed day can be restated by a venue for one to two days; the harness re-reads the last three days every hour. Not a measure of organic flow: incentive programs and wash trading inflate notional on every venue.

Volume / OI (24h)
Astern/aExtendedn/a

The ratio is a screen, not a verdict. Both terms are the venue's own figures (24h volume and open interest as each API reports them, in USD), so a venue that counts both legs of a fill moves its ratio without changing anything real. A very low ratio (Ostium, 0.2x) means positions held for days on thin daily volume; a very high one (Kalshi, above 40x) means a day of trading dwarfs what stays open. The bands in the methodology say what each range usually means.

Funding paid, 30d ETH long
Astern/aExtendedn/a

Every row is a month of funding at the venue's average daily cost over the hours measured in the trailing 30 days (average x 30). A venue ranks only with 576 of the 720 hours (24 days) behind that average; under the floor the row is provisional, unranked, and shows its day count (the venues added on 2026-09-22 and 2026-09-23 start there). Funding is signed: on a month where shorts paid longs the figure is negative and "cheapest" means "was paid the most".

How this pair was selected

Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing; panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.

Live data refreshes via ISR within 60 seconds of a new run. Sources are the same Prometheus queries surfaced on the parent benchmark pages.
