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.
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.
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.

How is the GMX vs Ostium comparison measured?
Every benchmark on this page uses the same open methodology, published at https://openchainbench.com/methodology. Data is CC-BY-4.0. Measurement harnesses are MIT-licensed.
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.
