How does Lighter perpetual trading work?

Good question — let me lay out how it works conceptually, then give you the real usage picture.

How Lighter perpetual trading works

The core mechanism (perpetuals 101): You're not buying or selling the actual asset. You're opening a leveraged position on its price — long (you profit if price rises) or short (you profit if it falls). No expiry, so you hold as long as you like, but you're required to keep margin (collateral) in the position, and if price moves against you past your maintenance margin, you get liquidated — your collateral is seized to close the position.

What makes Lighter different from a typical perp DEX:

• Orderbook-based, not AMM. A lot of perp DEXs (like GMX) are LP-vs-trader — you trade against a liquidity pool that takes the other side. Lighter uses a central limit order book: your orders match against other traders' orders, more like a centralized exchange. That tends to mean tighter spreads and better pricing on liquid pairs.

• Verifiable matching and liquidations (the "zk" in zkLighter). The matching engine that pairs buy and sell orders runs off-chain for speed, then produces a cryptographic proof (a zero-knowledge proof) of what it did. Anyone can verify on-chain that every match and every liquidation was computed correctly — so you don't have to trust the engine, you can verify it. That's the core selling point: CEX-level performance (fast orderbook, precise liquidations) with decentralized, trustless settlement.

• Self-custody. Your funds stay in smart contracts the whole time — there's no exchange counterparty sitting on your coins, which is the usual centralized-exchange risk.

Real usage picture (per DefiLlama): Lighter is currently generating roughly $399K in daily fees and about $372K in daily protocol revenue — making it one of the higher-revenue perp DEXs in the rankings, behind Hyperliquid and Jupiter but ahead of several others. (Daily volume isn't shown — DefiLlama's derivatives volume data needs a paid plan, so fees/revenue are the closest free proxy for usage.)

That's the general mechanics. If you want, I can break down a specific part — say how collateral and liquidation price are actually computed, or how it compares head-to-head against Hyperliquid/GMX — or dig into a specific market's data.

(Not financial advice — just how the protocol works.)
