Lighter

Built on the Ethereum layer 2 (L2) infrastructure, Lighter is a decentralized exchange (DEX) designed to provide verifiable, on-chain trading with zero fees for retail traders and competitive fees for high-frequency traders. Operating as a custom ZK rollup, Lighter inherits the security and composability of Ethereum while achieving low latency and scalability.

Lighter's technology features a highly optimized infrastructure for matching orders and proving the correctness of the matching process. This is made possible through the use of custom ZK circuits, which enable the generation of ZK proofs for all operations, including order matching and liquidations. The platform's matching engine processes tens of thousands of orders and cancels per second with millisecond latency, making it suitable for high-frequency trading. Furthermore, Lighter's use of Ethereum as the base layer for proofs and system state changes ensures secure and publicly verifiable transactions.

As a fully verifiable DEX, Lighter provides a unique value proposition to traders by offering zero fees for retail traders and competitive fees for high-frequency traders. The platform's scalability and low latency make it an attractive option for traders seeking to execute trades quickly and efficiently. Additionally, the use of ZK proofs ensures that all operations are cryptographically proven and publicly verified on Ethereum, providing an added layer of security and transparency.

Lighter has received backing from top-tier venture capital firms, including Ribbit Capital, Haun Ventures, Robinhood, and Coinbase. The platform's founders have a strong track record in the field of decentralized finance (DeFi), and their expertise has been instrumental in shaping Lighter's technology and features. With a growing community and increasing adoption metrics, Lighter is emerging as a leading player in the DeFi space.

Lighter's roadmap includes continued development and optimization of its technology, with a focus on improving scalability and reducing latency. The platform also plans to expand its range of financial instruments and trading pairs, making it an increasingly attractive option for traders seeking to access a wide range of assets. With its unique value proposition and strong technical features, Lighter is well-positioned to become a leading player in the DeFi space.
