USDi is an over-collateralized stablecoin created by Interest Protocol, the pioneering fractional reserve banking protocol on the Ethereum blockchain. This innovative platform enables users to earn interest on their deposits while providing a unique approach to stablecoin functionality. To mint USDi, users can deposit 1 USDC into the Interest Protocol, receiving 1 USDi in return. Conversely, users can burn their USDi to reclaim 1 USDC. Additionally, the protocol allows users to deposit various assets into a multi-collateral vault, enabling them to borrow USDi against their collateral. All holders of USDi benefit from automatic yield generation without incurring gas fees for staking. This efficient mechanism ensures that Interest Protocol can produce more loans with reduced liquidity risks compared to traditional lending protocols that rely on fractional reserves. Interest Protocol dynamically manages its reserve ratio—the proportion of USDC held in reserve versus the total USDi supply—through a variable interest rate system. This means that as the reserve ratio fluctuates, so do the borrowing and deposit rates for USDi, maintaining a balanced ecosystem. Developed by GFX Labs, which was founded in 2021, Interest Protocol aims to enhance web 3 applications that promote ownership and usability. Users can easily mint USDi by depositing USDC at Interest Protocol or acquire it through platforms like Uniswap.
