Project Overview

Hifi v3 is an overcollateralized stablecoin protocol that delivers predictable, fixed-rate liquidity by isolating collateral-specific risks and using a single unified liquidity pool. Borrowers can mint Hifi Dollars (HFD) against their collateral and enjoy longer-term borrowing with competitive rates, while real-time interest accrual maximizes protocol revenue for the Hifi DAO. The Protocol Stability Module (PSM) ensures peg stability of the stablecoin and instant conversions between HFD and other stablecoins.
