How it's counted. Open interest is the USD value of open perpetual positions (one side), valued at each market's current price; 24h volume is quote notional traded in the last 24 hours. Stablecoin quotes (USDT, USDC, USD1) count as $1. Shares are of the DEXs shown: a DEX whose API is unreachable is marked and left out rather than estimated. Aster and Lighter refresh every 5 minutes; Hyperliquid is live. For centralised exchanges see exchanges ranked by open interest.

Perp DEX FAQ

What is a perp DEX?

A decentralised exchange for perpetual futures: traders post collateral on-chain (or on the exchange's own chain) and trade perps without handing funds to a company. Hyperliquid runs its own L1; Aster and Lighter are the next largest by open interest.

Which perp DEX has the most open interest?

The table ranks Hyperliquid, Aster and Lighter by the USD value of open perpetual positions, read live from each exchange's public API. The leader and each venue's share update every few minutes. See all exchanges for centralised venues.

How are open interest and volume counted?

Open interest is one side of every open position, valued at the market's current price; 24h volume is the quote-currency notional traded in the last 24 hours. Aster publishes open interest one market at a time, so its figure covers its 30 most-traded markets, which the coverage table quantifies. Hyperliquid includes its HIP-3 builder-deployed markets.

Why do these numbers differ from DefiLlama or the exchanges' own sites?

Some trackers count both the long and the short side of open interest, or 30-day rather than 24-hour volume. Stablecoin-quoted prices are treated as $1, and a venue that is unreachable is left out of the shares rather than guessed. Nothing here is financial advice.
