Mero is a trustless, reactive liquidity protocol that enables users to earn yield and register Actions with their liquidity. It delegates liquidity to the most efficient locations through multi-utility liquidity pools, yield-farming strategies, off-chain bots (keepers), and customizable Actions. Users can deposit assets into Mero liquidity pools to earn yield. Additionally, they can make their liquidity reactive by registering their Mero LP tokens to Actions. Registered LP tokens will continue to earn yield and Mero rewards until user-defined conditions are met and liquidity is sent to where it is needed.
