Mai Finance is a website that connects users to the QiDao Protocol, which is Polygon's first native stablecoin protocol. It is self-sustaining, community-governed, and decentralized. Loans are secured by always having more value locked than the amount of debt given out. Loans are paid out and repaid in MAI (a stablecoin soft pegged to the USD). QiDao consists of overcollateralized vaults, where MAI stablecoins are fully backed by collateral. Users deposit token collateral and borrow MAI through user-managed vaults. MAI is built on market incentives and penalties, with no centralized authority or algorithm controlling the protocol. Additionally, QiDao has two tokens: MAI, the stablecoin, and Qi, the governance token.
