MM Finance is a decentralized exchange (DEX) and automated market maker (AMM) platform built on the Cronos Chain. The platform claims to offer low trading fees, which are further reduced through a trade mining program that provides fee rebates. MM Finance also claims to be the first platform to introduce "Protocol Owned Liquidity" (POL) into its DEX, which could provide additional benefits and liquidity to users of the platform. The use of blockchain technology in the platform allows for secure and decentralized trading of cryptocurrencies and other digital assets.
