Lighter.xyz (zklighter)

Lighter is a high-performance ZK-rollup DEX offering perpetual futures and spot trading with sub-second finality. It supports 220+ markets (perpetuals for crypto, stocks, forex, commodities; spot pairs like ETH/USDC). All orders are signed L2 transactions settled on the deployment's L1.

Networks — the user MUST pick one

Lighter runs as two independent deployments. They share the same API shape but have different hosts, accounts, API keys, contracts, markets and quote assets. Credentials from one do not work on the other.
