What is Lighter?
Lighter is a decentralized exchange for perpetual futures built on a bespoke zk‑rollup called zkLighter. This platform delivers fully verifiable order matching and liquidation, using cryptographic proofs to guarantee fairness—”don’t trust, verify.” Operating at sub-5 ms latency, it supports tens of thousands of trades per second with transparent verification of every transaction.
The protocol prioritizes both speed and trustlessness: orders are matched off-chain by the zk rollup sequencer, with proofs generated that smart contracts validate on-chain. This ensures price-time priority, censorship resistance, and MEV mitigation. It uses a decentralized insurance fund to protect against edge-case liquidations, and supports advanced features like sub-accounts, API keys, and public pools.
With its combination of zk-rollup scalability, verifiable fairness, and CEX-grade performance, Lighter redefines what decentralized derivatives trading can look like—offering secure, transparent, and efficient perpetual futures on-chain.
