OpenEden is a Real World Asset tokenization platform that brings the yield of traditional financial instruments on-chain. The ecosystem's core product is TBILL, a token providing economic exposure to a portfolio of short-term U.S. Treasury bills and related liquid instruments. The project combines a regulated investment fund, institutional asset management, and smart contracts, connecting traditional fixed-income infrastructure with on-chain settlement. By 2026, OpenEden had expanded beyond TBILL with the yield-bearing USDO stablecoin and additional tokenized strategies, while U.S. Treasury bills remained a fundamental part of its infrastructure.

1. OpenEden and the Tokenization of U.S. Treasury Bills
OpenEden was founded in 2022 and specializes in the tokenization of traditional financial assets. The project operates at the intersection of TradFi and DeFi: real securities are held within a regulated financial structure, while rights to the economic value of the portfolio are represented by digital tokens. This model enables blockchain technology to be used for recordkeeping, transfers, and interaction with supported on-chain applications.
OpenEden's primary product is the Treasury Bills TBILL Vault. It provides eligible investors with access to a portfolio of short-term U.S. Treasury obligations. Instead of opening a brokerage account and purchasing individual T-bills, an investor completes the required onboarding process and receives TBILL, whose value reflects the economic performance of the underlying portfolio.
TBILL should not be treated as a conventional stablecoin pegged to the U.S. dollar. The token represents an interest in a regulated investment structure and is designed to pass the economic performance of the underlying assets to its holders. The portfolio primarily consists of short-term U.S. Treasury bills and may also include a limited cash allocation and reverse repurchase transactions collateralized by U.S. government securities.
OpenEden therefore addresses one of the main objectives of the RWA sector: turning a traditional money-market instrument into a programmable on-chain asset. Tokenization, however, does not eliminate the underlying legal infrastructure. TBILL still relies on an investment fund, asset manager, custodian, KYC and AML procedures, and defined subscription and redemption rules.
2. TBILL: Token Backing, Yield, and Fund Structure
TBILL is issued by a regulated professional fund in the British Virgin Islands. According to OpenEden's documentation, the token is backed on a 1:1 basis by a portfolio of short-term U.S. Treasury bills and a limited amount of cash. Returns for holders are generated by the performance of the underlying portfolio rather than through the issuance of a separate speculative reward token.
The underlying portfolio is managed by BNY Investments, while BNY provides custody services for the relevant traditional assets. This separation of responsibilities is important to the tokenization model: OpenEden provides the digital and blockchain infrastructure, while the management and custody of the underlying financial instruments remain integrated with institutional financial infrastructure.
| Component | Type | Role in the OpenEden Ecosystem |
|---|---|---|
| TBILL | Tokenized RWA | Provides exposure to a portfolio of short-term U.S. Treasury bills |
| TBILL Vault | Smart Contract Vault | Infrastructure for TBILL subscriptions, redemptions, and accounting |
| U.S. T-Bills | Government Securities | Primary underlying assets of the TBILL portfolio |
| BNY Investments | Asset Manager | Manages the underlying portfolio of the TBILL Fund |
| USDO | Yield-Bearing Stablecoin | Dollar-denominated token whose yield is linked to reserve assets |
| cUSDO | Wrapped Yield-Bearing Token | Non-rebasing version of USDO designed for DeFi and other applications |
TBILL subscriptions have historically been structured around eligible investors depositing USDC. After completing onboarding and having a wallet added to the whitelist, users can interact with the TBILL Vault. The smart contract therefore automates part of the investment process without turning the product into a fully permissionless DeFi protocol.
TBILL yield changes with the performance of the underlying portfolio and prevailing market interest rates. If yields on short-term U.S. government securities decline, the potential return generated by the tokenized product may also decrease. TBILL should therefore not be viewed as an instrument with a permanently fixed APR, as its economics remain connected to money-market conditions and interest-rate policy.
3. Ethereum, XRP Ledger, and OpenEden's Blockchain Infrastructure
OpenEden uses public blockchains as a settlement and programmable layer built on top of traditional financial assets. Its on-chain infrastructure makes it possible to track token issuance, execute permitted transfers, and integrate tokenized assets with compatible financial applications. Critical transactions involving the underlying securities, however, continue to take place outside the blockchain.
TBILL's original infrastructure was closely associated with Ethereum. In August 2024, OpenEden also announced the introduction of tokenized U.S. Treasury bills on the XRP Ledger. As part of the initiative, Ripple announced its intention to allocate $10 million to TBILL, providing an example of institutional use of tokenized government securities within the XRPL ecosystem.
Multichain expansion has practical significance for RWA products. The more networks and applications capable of supporting a tokenized instrument, the broader its potential use cases become, including treasury management, collateral, settlement, and DeFi integrations. However, technical availability on a blockchain does not override restrictions imposed by the issuer or applicable regulation.
OpenEden later expanded its blockchain strategy through USDO and cUSDO. Ethereum and Base have been used for these assets, while cUSDO was launched on Solana in December 2025. OpenEden also integrated Chainlink CCIP and Proof of Reserve into the USDO infrastructure. As a result, the project has gradually evolved from a single Treasury vault into multichain infrastructure supporting several types of tokenized financial products.
4. Regulation, Ratings, and Risks of Tokenized T-Bills
One of the main differences between OpenEden and permissionless RWA protocols is its regulated structure. The TBILL Fund is registered as a Professional Fund and regulated by the British Virgin Islands Financial Services Commission. Direct access to TBILL requires investors to complete KYC and KYT procedures, sign the relevant documentation, and satisfy the fund's eligibility requirements.
In 2024, TBILL became the first tokenized U.S. Treasury fund to receive an investment-grade rating from Moody's. The fund subsequently received an AA+f/S1+ rating from S&P Global Ratings. These ratings relate to characteristics of the fund and its portfolio and should not be interpreted as eliminating investment, operational, or technological risks.
Key Features of OpenEden and TBILL:
- tokenization of short-term U.S. Treasury bills;
- TBILL backing through a portfolio of real financial assets;
- a regulated Professional Fund in the British Virgin Islands;
- institutional management of the underlying portfolio through BNY Investments;
- use of public blockchains for token issuance and recordkeeping;
- KYC, KYT, and wallet whitelisting for direct access to the TBILL Vault;
- on-chain transparency for tokenized asset operations;
- support for multiple blockchain ecosystems;
- USDO and cUSDO as an additional layer of Treasury-backed infrastructure;
- integration of tokenized RWAs with institutional and DeFi use cases.
Access to TBILL is restricted by the product's eligibility and jurisdictional requirements. Under its current structure, the tokens are intended for qualifying professional investors who have completed the fund's verification procedures. This makes TBILL fundamentally different from ordinary ERC-20 assets that can generally be acquired without interacting with a regulated issuer.
In addition to interest-rate risk, investors need to consider issuer, custody, smart-contract, liquidity, and blockchain infrastructure risks. The availability and liquidity of a tokenized instrument may also depend on its subscription and redemption mechanisms. The government-backed nature of the underlying U.S. Treasuries reduces certain portfolio credit risks but does not make the tokenized product itself risk-free.
5. USDO and the Expansion of OpenEden's RWA Ecosystem
The next stage in OpenEden's development was OpenDollar (USDO), a regulated yield-bearing stablecoin issued by OpenEden Digital, which is licensed by the Bermuda Monetary Authority under the Digital Asset Business Act. USDO is designed to maintain a value of approximately $1, while income generated by reserve assets is distributed to holders through daily rebasing.
For DeFi applications, OpenEden provides cUSDO, a non-rebasing version of the token. The amount of cUSDO held in a wallet remains unchanged, while the value of each token increases as yield accrues. Users can convert USDO into cUSDO and back, making the asset easier to integrate with lending protocols, decentralized exchanges, and other on-chain infrastructure.
USDO gained several integrations during 2025–2026. In April 2025, OpenEden reported that the product had surpassed $100 million in TVL less than two months after launch. USDO and cUSDO were subsequently integrated into DeFi, payment, and institutional infrastructure, while FalconX added support for USDO for eligible institutional clients in 2026.
At the same time, OpenEden began expanding beyond government securities. In 2026, the ecosystem introduced HYBOND, linked to a short-duration high-yield corporate bond strategy managed by BNY Investments. This expanded OpenEden's model from tokenized T-bills toward broader on-chain fixed-income infrastructure.
OpenEden uses blockchain as an additional infrastructure layer for regulated financial assets. TBILL provides access to a portfolio of short-term U.S. Treasuries, while USDO and cUSDO adapt reserve-backed yield for use across the digital economy. The ecosystem's future development will depend on RWA regulation, interest rates, institutional demand, and liquidity across tokenized markets.
