Izumi Finance is introducing Programmable Liquidity as a Service (LaaS) on Ethereum with Uniswap V3 and will extend the liquidity service to multi-chains with built-in DEX. The goal is to help liquidity providers earn more liquidity mining rewards and trading fees while enabling protocols to attract liquidity in an efficient and lasting way. Izumi uses LiquidBox to provide incentive rewards in certain price ranges, enhances capital efficiency, and addresses the "pool 2 dilemma" by offering structured-incentive and auto-rebased modules. The LaaS roadmap includes supporting limit orders and being compatible with orderbook and Uniswap V3 to enhance capital efficiency for multi-chains. Izumi also aims to offer fast, decentralized, and low-cost cross-chain bridges.
