Impact is how far the average fill of a market order lands from mid. Reported volume says how much traded, not what your order would meet: CoinMarketCap put the 24-hour volume of Hyperliquid at $13.4 billion on 22 September 2026, yet its BTC book held $9.6 million within 10 bps in the snapshots. The window is short so far — a median of 114 readings a venue, 109 on edgeX, which is the fewest — and the order updates as it grows. Leverage shortens the distance between the entry price and the liquidation price, and the whole margin sits inside that distance. Depth decides how cleanly that distance is crossed: the thinner the book, the further from the mid price a forced close fills. ## How the readings were taken Two kinds of number reach this screen. Depth, spread and price impact are ours — every BTC perpetual book polled on a ten-minute tick, 18 September 2026 12:02 UTC to 19 September 2026 09:10 UTC, no account opened and no order sent, each median printed with the count of readings behind it. The rest is read off each venue's own documentation and trading terms on 18 September 2026: rate cards, market lists, leverage ladders, sign-in and access rules, audit history. Six weighted criteria, fixed on 18 September 2026 and unmoved since, turn those readings into the 8 totals on this page ([How we rate](/methodology)). This page orders venues by median depth within 10 bps; the score column is the site-wide score from [How we rate](/methodology). Custody, settlement and the security record are marked off documents, and a document is a statement of intent — none of it has been put under stress here. The fee column is the entry-tier rate a new account is quoted, with volume tiers, rebates and cashback left out of it. Depth was read on the BTC book alone, the deepest contract every one of these venues runs, so a venue that reads well on this screen can still be thin in a smaller market. Venues priced from an oracle or a pool never had a resting book to read, and carry their facts without a total on the [perp DEX list](/perp-dex-list). ## Sourced quotes > "Users can submit critical exit operations—such as withdrawals, public pool exits, or reduce-only IOC orders—on-chain, ensuring that the Sequencer must process them within a predefined timeframe." — Lighter documentation, Technical architecture, 18 September 2026. https://docs.lighter.xyz/about-lighter/technical-architecture-lighter-core > "HyperCore includes fully onchain perpetual futures and spot order books.

Bitcoin. Every venue on this page quotes its deepest perpetual on BTC, which is why BTC is the book read. In the snapshots edgeX held a median $29.5 million within 10 bps, against $26.8 million on Binance's BTC book read the same way. ### Which dex has the most volume? Hyperliquid. CoinMarketCap put the 24-hour volume of Hyperliquid at $13.4 billion on 22 September 2026, ahead of $3.2 billion for Aster and $2.0 billion for Lighter. Volume counts what traded; the depth on this page is what a new order would meet. ### Is high or low liquidity better crypto? High liquidity. A deep book fills market orders close to the quoted price and stops out leveraged positions less violently. In the snapshots a $100,000 BTC market order moved the price 0.06 bps on Hyperliquid but 6.95 bps on dYdX, a gap that grows with order size. ### Which Perp DEX has the highest volume? Hyperliquid, with $13.4 billion of 24-hour volume on CoinMarketCap on 22 September 2026. Highest volume and deepest book are different tests: in the BTC snapshots edgeX held the most orders within 10 bps of the mid price, at $29.5 million. ### Which DEX is best for perps? On liquidity alone, edgeX leads this page. On our site-wide score, which also weighs fees, custody, security, market count and access, Lighter leads with 8.5/10. The two lists differ because measured depth is only one quarter of the overall score. ### cex futures vs perp dexes, what are the real tradeoffs? Depth is one tradeoff. Binance's BTC book held a median $26.8 million within 10 bps in the snapshots, against $29.5 million on edgeX, the deepest venue here. In return, perp DEXs keep collateral in contracts and ask for no identity documents. ### What are the top 5 dex? By measured BTC depth within 10 bps in the snapshots, the top five are edgeX, EVEDEX, Lighter, Aster and Hyperliquid. By reported open interest on CoinMarketCap, Hyperliquid leads at $8.7 billion, and the two rankings rarely match because open interest measures positions, not resting orders. ### How often do you read the books? Every ten minutes across the window named above, on every venue that publishes a public BTC perpetual book. Each figure on this page is the median of those readings with the snapshot count beside it, so one quiet minute cannot set a venue's number on its own. ### Which crypto dex is best? It depends on the order size. For $1 million BTC orders, edgeX moved the price least in the snapshots, 0.23 bps from mid. For small orders, fees matter more than depth, and Lighter charges 0% on its default account. Depth and fees pull in different directions, so the size of the order decides which to weigh. ### Is there any Dex to trade legit cryptocurrencies? Yes. Every venue on this page lists BTC, ETH and SOL perpetuals, and the BTC books read here held between $845,322 and $29.5 million within 10 bps. These are futures contracts: you trade the price without holding the coin. Every depth figure here is a median of ten-minute readings, printed with the count behind it. ### What exchange you guys using for futures? We do not trade on the venues scored here. For liquidity alone, the deepest books in the snapshots belonged to edgeX, EVEDEX and Lighter; check fees, custody and each venue's terms before choosing. Depth also shifts with the hour of the day, so one reading would never settle it. ## Editorial note One published formula, every figure dated and sourced. Corrections: editorial@spacesdao.org.
