As the blockchain industry transitions from crypto-native assets to traditional financial assets, a growing number of institutions are exploring ways to bring low-risk yield instruments—such as U.S. Treasury bonds and money market funds—onto the chain. U.S. Treasuries have long served as a foundational asset in the global financial system, and USDY leverages blockchain technology to lower the barrier to accessing them while enhancing asset composability and circulation efficiency.
Within the Ondo ecosystem, USDY is a key product that bridges traditional fixed-income markets with on-chain finance. Unlike stablecoins designed solely for value transfer, USDY introduces yield as a core attribute of digital assets, allowing users to hold on-chain dollar-denominated assets while gaining exposure to returns from U.S. Treasury bonds.
What Is Ondo U.S. Dollar Yield
Ondo U.S. Dollar Yield (USDY) is a tokenized yield asset backed by short-term U.S. Treasury bonds and bank deposits. It packages traditional financial market yield assets on-chain, enabling eligible investors to hold dollar yield exposure in digital form.
Unlike stablecoins pegged at $1, USDY is not designed to maintain a fixed price. Instead, it continuously generates yield from its underlying assets, with accumulated returns reflected in changes to the token’s value. As such, USDY more closely resembles an on-chain yield certificate than a traditional payment stablecoin.
Why USDY Was Created: The Need for Yield-Bearing Dollar Assets
Stablecoins have become a critical infrastructure component of the digital asset market, yet most do not pass the yield generated by their underlying reserves back to holders. While users maintain dollar exposure, they cannot directly access the interest income from the U.S. Treasury market.
At the same time, U.S. Treasuries have long been considered one of the most liquid fixed-income assets with the lowest credit risk globally. As interest rate environments shift, market demand for on-chain dollar yield products continues to grow. USDY was launched against this backdrop, combining the yield-generation capacity of traditional finance with the liquidity advantages of blockchain.
What Are the Underlying Assets of USDY?
USDY’s value is primarily derived from real-world asset (RWA) support.
Its underlying assets typically include short-term U.S. Treasury bonds and a portion of bank demand deposits. These assets are managed and custodied by regulated financial institutions and are linked to on-chain tokens through established legal structures.
U.S. Treasury bonds provide the primary source of yield, while bank deposits support daily liquidity needs and fund management. This combination allows USDY to strike a balance between yield generation and capital liquidity.
How Does USDY Generate Yield?
USDY generates yield from the interest paid by its underlying U.S. Treasury bonds.
When funds are allocated to short-term U.S. Treasuries, those bonds produce yield at prevailing market rates. After deducting related fees, this yield is reflected in USDY’s net asset value (NAV).
Unlike DeFi protocols that distribute yield via token incentives, USDY’s yield originates from real-world financial assets—making it an RWA-driven yield model. The income comes from the cash flow of the underlying assets, not from minting new tokens.
What Are the Differences Between USDY, USDT, and USDC?
USDY, USDT, and USDC are all tied to dollar-denominated assets, but their design objectives are distinctly different.
USDT and USDC are payment stablecoins whose core goal is to maintain an approximate 1:1 value relationship with the U.S. dollar. They are primarily used for trading, settlement, and cross-border transfers.
USDY, by contrast, is a yield-bearing dollar asset designed to pass U.S. Treasury returns to holders. As a result, USDY’s value tends to grow gradually as yield accumulates, rather than remaining fixed at a constant price.

What Are the On-Chain Use Cases for USDY?
USDY is becoming an important yield infrastructure in on-chain finance.
In DeFi protocols, USDY can be used as yield-bearing collateral for lending activities, allowing capital to earn additional returns while maintaining dollar exposure.
For DAO treasuries, USDY serves as a cash management tool, deploying idle funds into the U.S. Treasury market. Several cross-chain ecosystems also view USDY as a bridge connecting traditional financial yields with on-chain liquidity, thereby expanding the utility of RWA assets.
What Risks Does USDY Face?
Although USDY is backed by U.S. Treasuries, it is not entirely risk-free.
First, USDY carries operational risks associated with the issuer and custodian institutions. Second, on-chain assets remain exposed to smart contract and technical risks. Third, regulatory requirements for RWA products may change across different jurisdictions, potentially affecting the product’s circulation scope and compliance framework.
Additionally, while U.S. Treasuries are generally considered low-credit-risk, changes in market interest rates can still impact the value of the underlying assets. Therefore, USDY is a real-world asset product, not a risk-free asset.
Summary
Ondo U.S. Dollar Yield (USDY) is a yield-bearing tokenized asset backed by short-term U.S. Treasury bonds and bank deposits. It aims to bring dollar yield capabilities from traditional financial markets into the blockchain ecosystem. Compared to payment stablecoins like USDT and USDC, USDY focuses on yield generation, with value growth driven primarily by the interest income of its underlying U.S. Treasury holdings.
FAQs
What is the source of USDY’s yield?
USDY’s yield comes primarily from the underlying short-term U.S. Treasury bonds and a portion of cash deposits. This yield represents cash flow generated by real-world assets, not on-chain token incentives.
What is the difference between USDY and OUSG?
USDY is designed for a broader range of international eligible investors and uses a yield-bearing token structure. OUSG, on the other hand, represents tokenized U.S. Treasury fund shares. The two differ in legal structure, investor eligibility requirements, and product design.
Does USDY face de-pegging risk?
USDY does not aim to maintain a fixed price, so it does not face the traditional stablecoin de-pegging issue. Its price changes primarily reflect the net asset value and accumulated yield of the underlying assets.
Can USDY be used in DeFi?
Yes, USDY has been integrated by several DeFi protocols and on-chain ecosystems for lending, liquidity management, and treasury allocation. Specific support depends on the integration status of each blockchain network and protocol.
