Loopring is an Ethereum-based decentralized exchange protocol with an automated execution. Loopring is not a decentralized exchange. It is an infrastructure that enables decentralized exchange. Loopring is designed to allow any platform that uses smart contracts to integrate. By pooling all orders sent to its network, Loopring provides maximum liquidity and optimal pricing across exchanges and platforms. One of Loopring's unique features is that users don't need to deposit funds with an exchange. Tokens remain in wallets and are not locked by orders. In addition to not requiring direct deposits, the protocol has innovative mechanisms built in that allow for a series of trades to be bound together in an order ring to fulfill each other. The orders can then be split through order sharing, where partial orders will be filled until the whole amount is completely filled. This unique automated execution feature increases liquidity.
Loopring wants to become a cross-blockhain protocol. It has plans to integrate with NEO and Qtum.
