OpenEden is an RWA platform that brings traditional financial assets into blockchain infrastructure. Its key product, TBILL, provides qualified investors with tokenized economic exposure to a portfolio of short-term U.S. Treasury bills and related liquid assets. Instead of independently opening a brokerage account, users can complete KYC/KYB, deposit USDC into a smart contract, and receive TBILL in their own whitelisted wallet. The project combines a regulated fund structure, professional asset management, institutional custody, and onchain mechanisms for token issuance and redemption.

1. OpenEden: How US Treasury Bill Tokenization Works
OpenEden was founded in 2022 with a focus on tokenizing real-world assets. One of the project's founders and CEO is Jeremy Ng, who previously worked at Gemini in the Asia-Pacific region. The platform's first major product, TBILL Vault, was launched in 2023 as infrastructure connecting the U.S. government securities market with stablecoin liquidity and DeFi.
TBILL is based on short-term debt obligations issued by the U.S. Department of the Treasury. Traditionally, investors need to interact with a bank, broker, or fund to access such instruments. OpenEden retains a regulated fund structure while adding a blockchain layer: subscription, issuance, and redemption of interests are represented through the TBILL token and smart contracts.
Investors complete KYC/KYB and wallet verification, after which their addresses are added to a whitelist. USDC can then be deposited into the TBILL Vault, with users receiving TBILL in return. The tokens are held in the investor's self-custody wallet and represent their contractual economic interest in the corresponding share of the fund's net asset value.
TBILL is therefore not a conventional stablecoin with a fixed price of $1. Its value reflects the portfolio's NAV, while income generated by the underlying assets is gradually reflected in the token price. This model brings the economics of short-term government securities into an onchain environment without turning the Treasury bills themselves into freely transferable permissionless tokens.
2. TBILL: Token Structure, Yield, and Redemption
TBILL is an EIP-20-compatible token linked to an investor's economic interest in a regulated fund. The underlying portfolio consists primarily of short-term U.S. Treasury securities and liquid U.S. dollar assets. Investor returns are not generated through the issuance of new TBILL tokens but instead reflect the performance of the underlying portfolio after applicable expenses.
The price of TBILL is calculated based on NAV. As income from Treasury securities accumulates, the token's value may increase. However, this growth is neither guaranteed nor strictly linear: the market value of bonds is sensitive to interest rates, while the final return depends on portfolio composition, expenses, and market conditions.
Key stages of using TBILL:
- Onboarding — the investor completes KYC/KYB, KYT, and eligibility checks required by the fund.
- Whitelisting — the approved blockchain address is added to the list of authorized wallets.
- Subscription — the user deposits USDC into the TBILL Vault.
- Minting — the smart contract issues the corresponding amount of TBILL.
- Self-custody — the tokens are held in the investor's whitelisted wallet.
- Transfer — TBILL can be transferred between addresses that meet the applicable requirements.
- Redemption — TBILL tokens are burned, after which the investor receives the corresponding amount in USDC, less applicable fees.
The product is primarily designed for professional and accredited investors. According to OpenEden's documentation, the initial subscription is subject to a relatively high minimum threshold, while subsequent transactions may be conducted with smaller amounts. Standard redemption requests are processed through a FIFO queue and are generally completed on the next U.S. business day.
3. Regulation, BNY, and OpenEden TBILL Backing
The legal structure is a fundamental component of TBILL. The tokens are issued by Treasury Bills Institutional Liquidity Limited, a professional fund registered in the British Virgin Islands and regulated by the British Virgin Islands Financial Services Commission. The technology infrastructure for TBILL Vault is provided by River Labs, although the technology company itself does not act as a bank or custodian.
In August 2025, OpenEden appointed BNY entities to provide investment management and primary custody services for the underlying assets of the TBILL Fund. BNY Investment Management Singapore manages the portfolio of short-term Treasury instruments, while BNY-affiliated entities provide institutional-grade custody. The ecosystem also relies on independent fund administration, auditing, blockchain compliance, and other specialized services.
| Component | Function | Role in the TBILL Structure |
|---|---|---|
| TBILL Fund | Regulated professional fund | TBILL issuance and ownership of underlying assets |
| US T-Bills | Short-term U.S. government debt | Primary source of portfolio yield |
| BNY | Investment management and custody | Management and custody of underlying assets |
| TBILL Vault | Smart contract infrastructure | Onchain subscription, issuance, and redemption |
| USDC | Settlement stablecoin | Deposits and withdrawals through the Vault |
| Fund Administrator | NAV calculation and oversight | Independent reporting on fund assets |
The institutional structure has also received assessments from international rating agencies. In 2024, TBILL became the first tokenized U.S. Treasury product to receive an investment-grade A-category rating from Moody's. In 2025, S&P Global Ratings assigned the fund an AA+f fund credit quality rating and an S1+ fund volatility rating. These ratings relate to the characteristics of the fund and its portfolio and do not mean that investment, technological, or operational risks are absent.
4. Blockchain Networks, DeFi, and the Project Ecosystem
OpenEden designed TBILL from the outset as an onchain financial instrument rather than simply a digital record of a traditional investment. Smart contracts handle token issuance, custody interactions, and redemption, while the status of the Vault can be verified directly on the blockchain. In parallel, an independent administrator provides NAV data for the underlying fund, connecting the onchain token supply with offchain assets.
Over time, the infrastructure became multichain. TBILL gained support for Ethereum, Arbitrum, Solana, and the XRP Ledger. In 2024, Ripple announced a $10 million allocation to TBILL as part of the development of tokenized Treasury assets on XRPL. In 2026, OpenEden continued expanding its XRP Ledger integrations, including collaboration with DeFi infrastructure designed to support the use of RWA assets.
Potential composability distinguishes tokenized T-bills from conventional access to a Treasury fund through a traditional broker. Subject to the necessary permissions, the token can function as a programmable financial asset: it can be held in a corporate treasury, transferred between whitelisted participants, or integrated into lending, collateral, and liquidity products. However, its permissioned structure limits the free transferability of TBILL compared with USDC or other public tokens.
Over time, the OpenEden ecosystem expanded beyond TBILL alone. In 2025, the company launched OpenDollar, or USDO, a regulated yield-bearing stablecoin whose reserves are linked to tokenized Treasury assets. EDEN was later introduced for governance, staking, and ecosystem incentives. TBILL, USDO, and EDEN serve different purposes and therefore should not be treated as interchangeable tokens.
5. OpenEden Risks and Development in the RWA Market
The primary financial risk associated with TBILL relates to its underlying portfolio. Despite the high credit quality of U.S. Treasuries, their market value depends on interest rates and assessments of the U.S. government's creditworthiness. Rising interest rates can temporarily reduce the value of previously issued securities. In addition, during periods of significant redemption activity, the fund must be able to convert assets into liquidity in a timely manner.
Tokenization also introduces specific risks, including smart contract vulnerabilities, compromised self-custody wallets, stablecoin infrastructure issues, blockchain network disruptions, and operational risks between onchain systems and traditional financial infrastructure. The counterparty model also involves an asset manager, custodians, a fund administrator, banks, and other service providers. TBILL smart contracts have undergone independent audits, but auditing does not completely eliminate technological risk.
Access to the product is restricted by regulatory requirements. TBILL Vault remains permissioned infrastructure: users must meet the criteria for professional or accredited investors, complete the required verification procedures, and use a whitelisted address. This distinguishes OpenEden from permissionless DeFi protocols but reflects the legal nature of tokenized securities and the requirements governing their distribution.
OpenEden demonstrates how the RWA market can connect a traditional fund with blockchain infrastructure without eliminating regulated asset management, custody, and KYC. TBILL brings economic exposure to short-term U.S. Treasuries into a programmable onchain format, while the continued development of USDO and other products expands this model. For the institutional market, key factors will remain the transparency of the underlying assets, the quality of the legal structure, redemption liquidity, DeFi integration, and the platform's ability to adapt to evolving regulation of tokenized financial assets.
