Loopring is a decentralized finance platform that provides protocols, infrastructure, and user-facing products for the future of finance. It offers low-fee, high-speed trading, swapping, liquidity provision, and payments while ensuring security of assets. The first zkRollup protocol on Ethereum is deployed by LOOPRING to prevent exchange and payment applications from accessing user assets. LOOPRING was founded by Daniel Wang and is an Ethereum-based project started in 2017. Users can access the decentralized exchange and payment platform through the LOOPRING Layer2 App and the LOOPRING Wallet, a self-custodial smart contract wallet.
