The Loopring Agreement is an open multilateral transaction agreement between tokens based on ERC20 and smart contract. Through this agreement, we can establish decentralized exchange applications without asset custody and fund freezing. It adopts decentralized technology to provide a zero-risk token exchange mode, and allows multiple exchanges to match the same order out of the chain and clear the settlement on the chain through competition. LRC is Loopring token on Ethereum. LRC holders can pay the minimum transaction costs; benefit from all network activities.
