USDY is Ondo Finance's retail-accessible tokenized note backed by short-duration U.S. Treasuries and bank deposits. As of May 2026, USDY holds roughly $2.1B in AUM across six chains and pays a variable yield to non-U.S. holders through a daily-rebasing or wrapped (rUSDY) form factor.
​

This deep dive walks through what USDY is, who can hold it, how the yield mechanics work, where it lives onchain, and which use cases have driven adoption in emerging-market dollar corridors.
​

USDY is a tokenized note issued by Ondo USDY LLC, secured by a portfolio of short-term U.S. Treasury securities and demand deposit accounts at U.S. banks. Unlike BUIDL or OUSG (which require institutional accreditation), USDY is structured for non-U.S. individual investors and select institutions, with a 40-day transfer restriction after subscription before tokens become freely transferable on permissionless venues.
​

Two form factors exist. The base USDY token rebases daily, meaning the token balance in a holder's wallet grows each day to reflect accrued interest. The wrapped variant, rUSDY, holds a constant 1.00 redemption value and instead increases in price per token, which makes it easier to use inside DeFi pools and lending markets that do not handle rebasing tokens cleanly.
​

USDY is available to non-U.S. retail and institutional investors. U.S. persons are excluded, and Ondo enforces this through KYC at subscription and ongoing transfer screening.
​

Eligibility in practice covers most of Latin America, parts of Asia (excluding sanctioned jurisdictions), Africa, and the Middle East. After the initial 40-day lockup, USDY can transfer permissionlessly between any wallets globally, though Ondo's terms still prohibit U.S. persons from acquiring or holding it. Secondary venues including decentralized exchanges and onchain money markets list USDY without gating the buyer side, which is a structural feature of the post-lockup design rather than a workaround.
​

USDY's AUM sits around $2.1B as of May 2026, per rwa.xyz, making it one of the three largest tokenized treasury products by holdings alongside BUIDL and USYC.
​

Growth has been concentrated in two cohorts: emerging-market savers using USDY as a yield-bearing dollar substitute, and onchain treasuries holding USDY as a productive cash equivalent. The Solana and Mantle deployments have driven the fastest 2026 growth, reflecting demand from retail-heavy ecosystems where Ethereum gas costs make small-balance holdings impractical.
​

USDY is live on Ethereum, Solana, Aptos, Sui, Cosmos (via Noble), and Mantle. Each deployment is the same legal claim on the underlying portfolio; the multi-chain footprint is an issuance pattern, not separate funds.
​

Bridging between chains uses Ondo's authorized burn-and-mint flow rather than third-party wrapped representations, which keeps the legal entitlement intact across networks. The Cosmos deployment routes through Noble, the same issuance hub that handles native USDC on Cosmos, and the Aptos and Sui versions launched in 2025 to reach Move-based ecosystems where stablecoin density was growing.
​

USDY's yield reflects the net return of the underlying portfolio (short Treasuries plus bank deposits) minus Ondo's management fee. The rate adjusts as Treasury yields move.
​

Through May 2026, the APY has tracked between roughly 4.0% and 4.5% net, in line with short-end Treasury rates. Yield accrues daily and flows to holders through balance growth (USDY) or token price appreciation (rUSDY). There is no claim period, no staking, and no opt-in: holding the token is the only action required.
​

The variable-rate nature matters for use cases. Lenders and DeFi protocols that integrate USDY treat the yield as ambient income on collateral rather than a contractual coupon, which changes how it interacts with leverage and liquidations.
​

The dominant use case is emerging-market dollar exposure with yield. Holders in markets with currency volatility (Argentina, Turkey, Nigeria, parts of Southeast Asia) use USDY as a productive savings instrument denominated in dollars.
​

Secondary use cases include onchain treasury management for DAOs and crypto-native companies, collateral inside decentralized lending markets that accept rUSDY, and a base asset for yield-bearing payment flows where merchants accept stablecoins and want the float to earn interest. Cross-border remittance corridors have also begun routing through USDY as a yield-bearing leg between fiat onramps.
​

OUSG and BUIDL are institutional-only and require qualified-purchaser or accredited-investor status. USDY is the retail-accessible counterpart designed for non-U.S. individuals.
​

OUSG (also from Ondo) wraps BUIDL plus a liquidity layer and serves accredited U.S. and global investors with same-day mint and redemption. BUIDL is BlackRock's institutional money market fund, distributed via Securitize, with $5M minimum subscriptions. USDY has no minimum and no accreditation requirement, but excludes U.S. persons entirely. The three products together cover most of the addressable market: BUIDL for U.S. institutions, OUSG for global accredited investors, USDY for non-U.S. retail.
​

USDY's main risk vectors are smart contract risk, custody risk at the underlying banks, interest rate risk, and jurisdictional risk if holder residency changes.
​

The underlying portfolio is short-duration, which limits mark-to-market sensitivity, but USDY is not a stablecoin and does not target $1.00. The token price (or balance) reflects actual portfolio NAV plus accrued interest. Ondo publishes attestations of the underlying holdings monthly, and the legal structure provides bankruptcy-remote isolation of investor assets at the issuer level. Holders who become U.S. persons after subscription should review Ondo's transfer terms; the 40-day lockup applies to fresh subscriptions only, not to ongoing residency changes.
