Loopring is an open protocol for building scalable non-custodial exchanges on Ethereum. Leveraging zero-knowledge proofs (zkRollup), it allows for high performance trading (high throughput, low settlement cost), without sacrificing Ethereum-level security guarantees. Users always maintain 100% control of their assets throughout the trade lifecycle. You can trade on Loopring to test it out. Loopring is an open-sourced, audited, and non-custodial exchange protocol, which means nobody in the Loopring ecosystem needs to trust others. Cryptoassets are always under users' own control, with 100% Ethereum-level security guarantees. Loopring powers highly scalable decentralized exchanges by batch-processing thousands of requests off-chain, with verifiably correct execution via ZKPs. The performance of underlying blockchains is no longer the bottleneck. Loopring performs most operations, including order-matching and trade settlement, off the Ethereum blockchain.

Unichain is a DeFi-native Ethereum L2, optimized to be the home for liquidity across chains. Unichain is a decentralized finance (DeFi) platform designed as an Ethereum Layer 2 solution, focused on liquidity and cost efficiency. It offers faster, cheaper transactions with 1-second block times and aims to reduce transaction fees by 20x compared to Ethereum. Built on the OP Stack, it promotes scalability, open-source innovations, and future enhancements like Provable Block Building. Unichain targets developers and users in the DeFi space, providing resources for smart contract deployment and liquidity pool creation​. Informed by our experience building the world's largest decentralized trading protocol. Unichain is built on the OP stack. Technical innovations introduced by Unichain are open source, and available for any rollup to adopt. A network of full nodes monitors and verifies the actions of the sequencer, bringing faster transactions and more decentralization to Unichain.
