USDY (U.S. Dollar Yield Token) is a yield-bearing stablecoin issued by Ondo Finance, designed to maintain a peg while providing income to holders. It is backed by a portfolio of short-term U.S. Treasury Bills and bank demand deposits, aiming to deliver the majority of the yield from these low-risk assets. USDY is marketed as an institutional-grade product with blockchain transparency, but its reliance on centralized custody and regulatory compliance introduces specific risks.
