Perp DEX volume share, live 30-day rolling notional ranked
30-day rolling perpetual futures notional volume in USD across major decentralized venues. Higher means more flow. Read live from each venue's public API.
This benchmark ranks the major onchain perp venues by 30-day rolling notional volume, in USD. Volume is the cleanest single-number proxy for where perpetual futures flow actually lives today. We poll each venue's public API every 5 minutes, sum the trailing 30 days of taker notional in USD, and publish a single gauge per venue. Hyperliquid, Lighter, GMX v2 and gains.trade are the cohort. Headline number is the 24h average of the 30d rolling sum, so a single noisy print does not move the ranking. The companion benches price the cost side (perp-fees for opening, perp-funding for holding); this one prices flow.
Methodology
The bench polls four perp DEX venues every 5 minutes for cumulative taker notional and exposes a rolling 30 day USD sum per venue. Sources: Hyperliquid info dayNtlVlm (per-asset day notional, summed and rolled into 30d), Lighter public stats endpoint (24h volume per market, rolled), GMX Subsquid synthetics-arbitrum (positionVolume by day), gains.trade onchain reads aggregated by indexer. Each value carries a freshness timestamp and a health gauge so a stale or errored venue does not poison the leaderboard. Higher is better.
Frequently asked
What does this benchmark measure?
The 30 day rolling notional volume of major perp DEX venues in USD. Headline is the 24h average of the rolling 30d sum so single prints do not skew the ranking.
Why 30 day rolling instead of daily?
Daily perp volume is too noisy for ranking, a single thin Sunday can flip positions. The 30 day window smooths the cycle and matches the cadence at which serious flow makers compare venues.
Why these four venues?
Hyperliquid, Lighter, GMX v2 and gains.trade are the cohort whose public APIs expose taker notional cleanly enough to compare without backfilling. Other venues join as their endpoints document the same series.
Is this the same as DeFiLlama volume?
Methodology is similar in spirit but each venue is queried directly here, not via an aggregator. Numbers should sit close to DeFiLlama on most days, divergences usually mean a downstream feed lagged.
