Loopring Exchange is Ethereum’s first and only zkRollup DEX. It is a completely non-custodial orderbook exchange that can replicate the high-performance trading experience of centralized exchanges. That means users can trade speedily and cheaply — without worrying about Ethereum congestion or gas fees — while maintaining self-custody and control of their assets at all times. Loopring Exchange is built atop the open-source Loopring Protocol.
