A dex with reactive liquidity

We have developed “Mangrove” an on-chain permission-less decentralised exchange based on a limit order book which offers unique services to liquidity providers: 1) capital-efficiency because it does NOT require offers to lock up liquidity; 2) price protection (aka last look) whereby offers can renege on their promise -eg if prices have shifted; 3) management of fractional liquidity with offers that can amplify and create ghost liquidity.
