88mph is a fixed interest rate lending protocol that allows users to earn a fixed yield rate and extra MPH tokens on their deposits. It is designed to be an on-chain, non-custodial protocol, that acts as an intermediary between users and third-party variable yield rate protocols (such as Compound and Aave), with the intent to offer fixed yield rates on user's capital. The yield rates are determined by the maturity period, which can be custom or preset. Additionally, the MPH tokens users receive can be staked to earn protocol revenues and voting rights.
