As demand for stable on-chain returns grows, more institutions and DeFi users are turning their attention to the asset class of "on-chain Treasuries." Unlike traditional stablecoins, which primarily serve payment and settlement functions, Ondo seeks to directly map U.S. Treasury yields to on-chain assets, enabling users to gain exposure to dollar-denominated returns on-chain.
In the current blockchain landscape, Ondo is regarded as one of the representative projects bridging TradFi (Traditional Finance) and DeFi (Decentralized Finance). Its product structure closely resembles money market funds or short-term Treasury funds in traditional finance, while also offering the composability of on-chain assets, cross-chain liquidity, and round-the-clock settlement capabilities.
What Is Ondo?
Ondo is a blockchain-based financial protocol focused on the tokenization of real-world assets. It provides yield-bearing dollar assets to on-chain users primarily through low-risk assets such as U.S. Treasuries and money market funds. Its core products include USDY, OUSG, and ONDO. Among these, USDY is more oriented toward yield-bearing dollar assets for general on-chain users, OUSG is closer to an institutional-grade U.S. Treasury fund product, and ONDO primarily serves governance functions.
Unlike traditional DeFi yield protocols, Ondo's source of return is not on-chain borrowing rates but interest income from real-world U.S. Treasuries. This is the fundamental difference between Ondo and most on-chain stablecoin protocols.
How Does Ondo Work?
The core logic of Ondo can be summarized as follows: After user funds enter the system, they are used to purchase real-world U.S. Treasury assets through a custodial structure. Smart contracts then issue corresponding yield-bearing tokens on-chain. Subsequently, the underlying Treasury returns are gradually reflected in the value of the on-chain assets, and users can eventually exit the system through a redemption mechanism.
Throughout this process, the on-chain tokens are not created out of thin air but form a mapping relationship with real-world assets. Holding USDY or OUSG on-chain essentially means indirectly holding the rights to returns from U.S. Treasury assets.
How Do Users Enter the Ondo System?
Users typically enter the Ondo platform using stablecoins (e.g., USDC) or fiat currency. Some products require KYC/AML compliance checks, especially OUSG, which is geared toward institutional users and usually has higher compliance requirements.
After users complete their subscription, funds first enter a custodial account. The system then converts the funds into dollar assets and uses them to purchase short-term U.S. Treasury ETFs, money market funds, or other low-risk cash management assets. Once the underlying assets are confirmed, the smart contract mints USDY or OUSG on-chain based on the corresponding asset value.
This process means that the issuance of on-chain tokens must be backed by real-world assets, making the structure more akin to asset-backed financial products rather than algorithmic stablecoins.
How Does Ondo Tokenize U.S. Treasuries?
The tokenization of U.S. Treasuries is one of Ondo's core mechanisms. After user funds enter the system, Ondo purchases corresponding U.S. Treasury assets through a custodian and a Special Purpose Vehicle (SPV). Smart contracts then map these assets into on-chain tokens.
Throughout the process, the underlying assets are typically held by an independent custodian rather than directly controlled by the protocol. This structure reduces the risk of asset commingling and enhances the independence of the underlying assets. Additionally, the SPV structure is used to isolate the operating entity from the real-world assets, so even if the protocol operator encounters issues, the underlying assets theoretically remain independent.
On the on-chain side, smart contracts are primarily responsible for token minting, burning, yield updates, and balance synchronization, thereby completing the mapping relationship between real-world assets and on-chain tokens.
How Is USDY's Return Generated?
USDY's yield primarily comes from interest income generated by short-term U.S. Treasuries, money market funds, and cash management assets. Unlike traditional stablecoins pegged at $1, USDY is closer to a "yield-bearing dollar asset."
Its return is typically reflected through a Net Asset Value (NAV) growth mechanism. For example, the number of USDY tokens a user holds may remain unchanged, but the asset value per USDY token increases as the underlying Treasury returns accrue. This means users do not need to manually claim interest; the returns are automatically reflected in the asset value.
In addition, Ondo has introduced versions that use a Rebase mechanism. In this model, the token unit price remains stable, while the number of tokens in the user's wallet automatically increases with yield. These two models are suited to different DeFi scenarios.
How Does Ondo's On-Chain Circulation Process Work?
Once USDY or OUSG is minted, it can circulate within the blockchain network. Ondo has already expanded to multiple ecosystems, including Ethereum, Solana, Mantle, Aptos, and Sui.
Unlike traditional Treasury funds, Ondo's assets can directly enter DeFi systems. Users can not only make regular transfers but also trade these assets on DEXs, use them as collateral for lending, or transfer them between different networks via cross-chain bridges.
This on-chain liquidity and composability is one of the core differences between Ondo and traditional Treasury funds. In traditional finance, Treasury products can usually only be traded in securities accounts, while Ondo allows these assets to directly participate in on-chain financial activities.
How Does Ondo's Yield Distribution Mechanism Work?
Ondo's yield ultimately comes from interest payments on the underlying U.S. Treasuries. As the underlying assets continuously generate returns, the custodial structure updates the fund's NAV, and the on-chain smart contract synchronizes the corresponding asset price.
For users, the entire yield distribution process is typically automated. Users do not need to manually claim interest or perform additional operations; the returns are automatically reflected in changes to the token's NAV or balance.
This mechanism is similar to accumulating ETFs in traditional finance, where returns are automatically reinvested, driving continuous growth in asset value.
How Does Ondo's Redemption Mechanism Work?
When users wish to exit the system, they need to initiate a redemption process. After users submit a redemption request, the smart contract locks or burns the corresponding tokens. Ondo then sells part of the underlying U.S. Treasury assets and returns dollars or stablecoins to the user.
Because the underlying assets are real-world financial assets, the redemption process is typically more complex than that of standard stablecoins. Some products may have minimum redemption amounts, T+1 or T+2 settlement timestamps, and compliance restrictions in different regions.
Therefore, Ondo is more akin to an "on-chain financial product" rather than a fully instant-settlement stablecoin system.
What Is the Difference Between Ondo and Traditional Stablecoins?
Many users may confuse Ondo products with stablecoins like USDT and USDC, but the underlying logic is fundamentally different.

Thus, Ondo is closer to an "on-chain Treasury fund" rather than a stablecoin in the traditional sense.
Why Is Ondo Attracting Institutional Attention?
Ondo's appeal to institutions is largely related to the current global interest rate environment. In a high-interest-rate cycle, U.S. Treasury yields have once again become a major direction for global capital, and Ondo offers a way to bring dollar-yielding assets directly on-chain.
For institutions, Ondo simultaneously meets yield requirements, on-chain liquidity needs, and compliance structure requirements. Its custodial mechanism, SPV architecture, and KYC processes are also closer to the product systems familiar to traditional financial institutions.
At the same time, the RWA market is expanding rapidly. More institutions are beginning to view on-chain Treasuries as an important entry point connecting traditional finance with blockchain finance, and Ondo has become one of the most representative protocols in this direction.
What Potential Risks Does Ondo Face?
Although the on-chain Treasury market is growing rapidly, its risks have not disappeared.
The first is regulatory risk. Since RWAs involve securities, funds, and cross-border financial regulation, different countries may adopt varying regulatory stances toward yield-bearing on-chain assets. The second is liquidity risk; the liquidity of on-chain tokens may not fully equal that of the underlying U.S. Treasuries, and discounts or redemption delays could occur in extreme market conditions.
Additionally, Ondo still relies on smart contracts, multi-chain bridges, and custodial systems, so on-chain security risks and technical risks persist.
Conclusion
Ondo's core mechanism is to map real-world assets such as U.S. Treasuries into on-chain yield-bearing tokens, allowing blockchain users to gain direct exposure to dollar-yielding assets.
Its complete process includes: user subscription, asset custody, U.S. Treasury allocation, on-chain token minting, yield accumulation, multi-chain circulation, and eventual redemption. Compared to traditional stablecoins, Ondo emphasizes "assetization of yield"; compared to traditional Treasury funds, it adds the composability and round-the-clock liquidity of blockchain assets.
