## Products

- [Lighter](https://thegrid.id/profiles/lighter): Lighter is a decentralized perpetual futures exchange on Arbitrum that uses zero-knowledge rollup technology for verifiable order matching and liquidations. The system processes thousands of operations per second with low latency through custom ZK circuits while maintaining cryptographic proofs of all matching engine operations and liquidation events. Users retain non-custodial control of assets with emergency on-chain exit capabilities. (Decentralised Exchange, Live, Main Product)
