Tokenized Treasury Bills 2026: How to Earn T-Bill Yield On-Chain
Tokenized Treasury bills are transforming how crypto investors access risk-free yield. Instead of navigating traditional finance infrastructure, you can now earn 4.5-5% APY directly in your wallet while maintaining full DeFi composability. This shift represents more than just convenience—it's redefining what's possible when real-world assets meet blockchain infrastructure. With $9B in tokenized US Treasury exposure and growing, T-bills have become one of crypto's most powerful primitives for yield generation and collateral backing.

What Are Tokenized Treasury Bills?
Tokenized Treasury bills are blockchain-native representations of US Treasury bills. Each token is backed by actual T-bills held in custody by traditional financial institutions. When you buy a tokenized T-bill like BUIDL or USDY, you're purchasing a claim on real Treasury securities held off-chain.
Here's how it works: A financial institution (like BlackRock or Franklin Templeton) purchases US Treasury bills from the government. They then issue tokens on blockchain—one token per underlying dollar of Treasuries. These tokens can be transferred, traded, and used in smart contracts while the actual Treasuries remain in secure custody.
The yield accrual mechanism is crucial. Rather than waiting for T-bill maturity to earn interest, tokenized versions accrue yield daily or in real-time. BUIDL, for example, accrues yield to your wallet every second. When you hold USDY, the token itself appreciates as underlying T-bills accrue interest.
Why does this matter? Traditional Treasury investing required brokerage accounts, identity verification, and millions to access institutional rates. Tokenization democratizes access: you can buy fractional amounts instantly from anywhere, and integrate that yield into DeFi protocols immediately.
Why Tokenize T-Bills?
Composability with DeFi
Traditional Treasuries are locked outside blockchain. Tokenized T-bills can be deployed as collateral for loans, used in yield farming protocols, or swapped instantly for other assets. This composability unlocks entirely new financial structures impossible in traditional finance.
24/7 Settlement
T-bill trading in traditional markets operates during business hours with 1-2 day settlement. Blockchain transactions settle in seconds, any time of day. This liquidity and speed fundamentally change how you can manage yield.
Fractional Ownership
Traditional T-bills have minimum purchase sizes. BUIDL, USDY, and OUSG allow you to buy for any amount—even $1. This accessibility brings institutional-grade yield to retail investors.
Global Access
Tokenized T-bills are accessible from any wallet, anywhere (subject to local regulations). Geographic barriers that limit traditional Treasury access disappear on blockchain.
Immutable Custody Records
Blockchain provides cryptographic proof of ownership and custody. Every transaction is verifiable and transparent, reducing counterparty risk and settlement uncertainty.
Market Overview
The tokenized Treasury market has grown explosively. Approximately $9B of the $19.4B total tokenized RWA market is dedicated to US Treasuries—that's 45% of all real-world assets on-chain. Here's a comparison of major products:

BlackRock BUIDL Deep Dive
BUIDL (Blackstone US Dollar Institutional Liquid Exchange-traded fund) is the market leader with $2.3B in assets under management. Launched in 2023, BUIDL represents BlackRock's institutional-grade entry into tokenized Treasury markets.
How BUIDL Works
When you purchase BUIDL, you're buying shares in a fund that holds short-term US Treasury bills and repurchase agreements (repos). The fund targets T-bills with remaining maturity of less than 6 months to maximize yield while maintaining flexibility.
The critical advantage: BUIDL accrues yield continuously. Rather than monthly or quarterly distributions, your BUIDL balance increases every block (roughly every 12 seconds on Ethereum). This means your capital compounds at the protocol level—no reinvestment friction.
Why Institutions Love BUIDL
BlackRock's institutional credibility gives BUIDL unmatched trust. No minimum investment, no accreditation requirements, unrestricted globally. The fund is structured as a traditional SEC-registered mutual fund, providing regulatory clarity that many crypto projects lack.
BUIDL has become the go-to collateral for stablecoin reserves. Ethena uses BUIDL to back USDe, MakerDAO has explored it, and multiple protocols integrate it for risk management. This utility drives demand and creates network effects.
Current Yield and Risks
BUIDL currently yields 4.7-5.2% depending on market conditions. The yield is backed by actual Treasury holdings, making it essentially risk-free from default perspective. However, smart contract risk exists (mitigated by BlackRock's audits), and regulatory changes could affect structure.
Ondo Finance Deep Dive
Ondo Finance has emerged as the largest independent issuer of tokenized Treasuries with $1.8B+ in TVL across their product suite. Unlike BlackRock, Ondo focuses on accessibility and DeFi integration with two distinct products.
USDY: Yield-Bearing Stablecoin
USDY is a stablecoin that appreciates as Treasury yield accrues. Unlike USDC or USDT (which maintain 1:1 peg), USDY grows in value. One USDY purchased today at $1 becomes worth $1.05+ in a year through accrued yield.
This design makes USDY perfect for DeFi integration. Protocols can use USDY as collateral, earn passive yield on treasury reserves, or offer USDY savings products. Unlike traditional collateral, USDY improves in value over time.
OUSG: Tokenized Short-Term Treasuries
OUSG (Ondo US Government Securities) provides direct exposure to short-term Treasury bills and coupons on blockchain. Unlike USDY, OUSG maintains a stable token price with yield distributions. This appeals to investors who prefer traditional yield structures.
OUSG is distributed across Ethereum and Base, improving accessibility and reducing gas costs. The product has attracted institutional attention due to transparent audit trails and regulatory cooperation.
Ondo's Advantages
Ondo combines institutional-grade Treasury management with crypto-native accessibility. Their multi-chain approach (Ethereum, Base, Arbitrum coming soon) provides flexibility. As an independent team rather than traditional finance giant, they're more responsive to DeFi needs while maintaining rigorous custody standards.
Franklin Templeton BENJI
Franklin Templeton's BENJI (short for BEN Franklin) represents a different approach to tokenized Treasuries. Rather than a new asset, BENJI is a blockchain representation of Franklin Templeton's existing US government money market fund.
One Share = One Token
The elegance of BENJI lies in its simplicity: one BENJI token equals one share of the fund. This 1:1 structure eliminates complexity and makes on-chain registry management straightforward. Shareholders maintain full regulatory clarity—they own registered fund shares, not derivative tokens.
Institutional Fund Structure
BENJI operates as a registered US government money market fund under Franklin Templeton's established infrastructure. This regulatory structure provides comfort to institutional investors and regulators alike. The fund invests in Treasury bills, Treasury notes, and highly-liquid short-term securities.
Use Cases
BENJI appeals to traditional finance institutions entering crypto, compliance-conscious investors, and those seeking the comfort of established money market fund structures. Minimum investments typically start at $10k, positioning it for institutional adoption rather than retail accessibility.
How T-Bills Are Becoming DeFi's Foundation
Tokenized Treasury bills represent more than investment vehicles—they're becoming core infrastructure for decentralized finance. The yield, stability, and regulatory clarity they provide solve fundamental DeFi problems.
Collateral for Lending
Protocols like Aave and Compound are integrating BUIDL and USDY as collateral. Unlike volatile crypto assets requiring heavy overcollateralization, T-bills enable capital-efficient lending. Borrowers can use $100 of T-bills as collateral for $80-90 of loans, improving system efficiency.
Stablecoin Backing
The most impactful use case is stablecoin reserves. Ethena uses BUIDL to back USDe, solving stablecoins' historical peg problems. Rather than centralized reserves or over-collateralization, stablecoins backed by Treasury bills inherit government-backed security.
Treasury Management for DAOs
Decentralized organizations managing millions in treasuries face the "stablecoin yield" problem: how to earn on reserves without taking risk? USDY and OUSG enable DAOs to earn 5% on treasuries while maintaining complete on-chain control and composability.
Yield Farming Enhanced
Advanced yield strategies combine T-bill collateral with DeFi protocols. For example: deposit BUIDL as collateral, borrow USDC, supply USDC to yield farms, earn protocol token rewards while collecting underlying Treasury yield. This stratified approach generates multiple yield layers simultaneously.
Real-Yield Benchmarking
Tokenized Treasuries provide DeFi's first true "risk-free rate" on-chain. This 4.5-5% yield becomes the benchmark for evaluating all other DeFi returns. Strategies yielding less than T-bill rates without additional risk exposure become uncompetitive.
Risks and Considerations
While tokenized Treasury bills offer compelling yield, several risks require consideration before investing.
Smart Contract Risk
All tokenized Treasury products depend on smart contract code. Bugs, exploits, or unforeseen vulnerabilities could compromise funds. Mitigate this by prioritizing products with professional audits (OpenZeppelin, Trail of Bits, etc.) and established track records. Start with smaller positions before deploying significant capital.
Regulatory Uncertainty
Regulations around tokenized securities continue evolving. Regulatory tightening could restrict usage, require KYC/AML, or limit participation. Some products like OUSG have already implemented identity verification. This may become industry standard.
Custodial Counterparty Risk
Your Treasury bills exist in physical or digital custody held by bank custodians. If a custodian fails (extremely unlikely but possible), your holdings face risk. Larger institutions like BlackRock and Franklin Templeton use major custodians (BNY Mellon, etc.), reducing this risk.
Liquidity Constraints
During market stress, liquidity for tokenized Treasury trades could tighten. Secondary market depth is growing but remains smaller than traditional Treasury markets. Plan to hold medium-term rather than relying on instant exit liquidity.
Redemption Mechanics
While most tokenized Treasury products support redemption, redemption to stablecoins (not direct USD) requires secondary market trades. Check each product's redemption process and any associated fees before investing.
Interest Rate Risk
If US interest rates fall significantly, Treasury yields decline. New BUIDL, USDY, and OUSG purchases would earn lower yields. This doesn't affect existing holdings but impacts future return expectations.
How to Get Started
Step 1: Choose a Product
Start by identifying which product suits your needs. BUIDL is best for institutional credibility and collateral use. USDY excels in DeFi integration. OUSG provides straightforward Treasury bill exposure. BENJI works for traditional finance integration. USDM suits Arbitrum users.
Step 2: Set Up a Wallet
You'll need a self-custodial wallet (MetaMask, Ledger, etc.) with ETH for gas fees and stablecoins (USDC, USDT) to purchase tokenized Treasuries. Ensure your wallet is secure and you have backup recovery phrases stored safely.
Step 3: Acquire Stablecoins
Obtain USDC or USDT from a centralized exchange or AMM. You'll trade these stablecoins for your chosen tokenized Treasury product on Uniswap, 1inch, or dedicated platforms like the official Ondo or BlackRock interfaces.
Step 4: Execute the Trade
Use a DEX to swap stablecoins for tokenized Treasury tokens. Start with a small amount to test the process. Verify you're using the correct contract address (check official sources, not random websites). Confirm gas fees before submitting.
Step 5: Monitor and Manage
Watch for yield accrual (BUIDL balance increases in wallet) or appreciate (USDY price rises). Consider deploying your holdings as collateral, in lending protocols, or in treasury management strategies. Review your positions quarterly for regulatory or product changes.
Step 6: Tax Considerations
Accrued yield on BUIDL and appreciated value on USDY may trigger taxable events. Consult a tax professional about treatment in your jurisdiction. Some jurisdictions tax unrealized gains, others only realized gains from sales. Proper documentation from day one simplifies tax season.
