USD.AI is a decentralized protocol that issues a synthetic dollar backed by traditional and real-world assets. The ecosystem features two tokens: USDai, a stablecoin collateralized by U.S. Treasury Bills, and sUSDai, a yield-generating version backed by T-Bills and tokenized infrastructure loans through MetaStreet’s Liquid Credit Tokens.
To manage liquidity efficiently, the protocol implements Queue Extractable Value (QEV) — an auction-based mechanism that prioritizes and prices withdrawal requests. USD.AI’s long-term goal is to evolve into a fully decentralized, token-governed credit aggregator supported by a wide range of collateral assets.
