Tokenized Treasuries 2026: Earn T-Bill Yield On-Chain with BlackRock & Ondo
Over $25 billion in US Treasury bonds now live on the blockchain. BlackRock's BUIDL fund crossed $2.3B in assets. Ondo Finance manages $1.8B+ in tokenized fixed income. Here's how tokenized treasuries work, who the key players are, and whether the yield is worth the tradeoffs.

1. What Are Tokenized Treasuries?
Tokenized treasuries are on-chain representations of US government bonds (T-bills, T-notes, or T-bonds). A fund manager like BlackRock buys actual US Treasury securities, then issues blockchain tokens that represent fractional ownership of those securities. Each token tracks the value of the underlying bond, accrues yield, and can be transferred peer-to-peer on a public blockchain — typically Ethereum, but increasingly on Solana, Avalanche, and other chains.
Think of it this way: instead of calling your broker to buy T-bills, you buy a token that represents T-bills and holds them in custody. The token earns yield (currently ~4–5% APY as of March 2026), can be used as collateral in DeFi protocols, and can be transferred instantly to anyone with a compatible wallet.
For years, DeFi stablecoins earned yield by farming crypto protocols at high risk. Now, that same stablecoin capital can earn risk-free US government yield — on-chain, composable with DeFi, and with 24/7 liquidity. This is a structural shift in how DeFi manages its "cash" positions.
2. How Tokenization Works
The process of getting a T-bill onto the blockchain involves several layers:
3. Key Players: BUIDL, Ondo, Franklin Templeton
| Product | Issuer | Chain(s) | AUM | Min. Investment | Yield |
|---|---|---|---|---|---|
| BUIDL | BlackRock / Securitize | Ethereum, Polygon | $2.3B | $5M (institutional) | ~4.8% APY |
| OUSG | Ondo Finance | Ethereum, Solana | $750M+ | $5K | ~4.6% APY |
| USDY | Ondo Finance | Ethereum, Solana, Sui | $500M+ | $500 | ~4.5% APY |
| FOBXX (Benji) | Franklin Templeton | Stellar, Polygon | $400M+ | $20 | ~4.7% APY |
| STBT | MatrixDock | Ethereum | $200M+ | $100K | ~4.5% APY |

🏛️ BlackRock BUIDL
BlackRock's USD Institutional Digital Liquidity Fund is the market leader by AUM and arguably the most significant development in the space. When the world's largest asset manager ($10T+ AUM) puts its name on a tokenized fund, it signals that institutional tokenization has crossed the threshold from experiment to mainstream financial infrastructure. BUIDL is currently available only to accredited institutional investors ($5M minimum), issued via Securitize, and runs primarily on Ethereum. It has served as the collateral backbone for several DeFi protocols, including a notable integration with Ondo as an underlying asset.
🟢 Ondo Finance
Ondo is the most DeFi-native player in the tokenized treasury space, and the one most relevant to crypto-native users. Their two flagship products — `OUSG` (Ondo US Government Bond Fund) and `USDY` (Ondo US Dollar Yield) — have different risk profiles and minimums. `USDY` in particular has become widely used as a yield-bearing stablecoin alternative, with just $500 minimum and availability on Ethereum, Solana, and Sui. Ondo recently expanded its product catalog to include over 200 tokenized stocks and ETFs — a significant move toward a broader tokenized securities platform.
🔵 Franklin Templeton (Benji)
Franklin Templeton's FOBXX is notable for being the first US registered mutual fund to use a public blockchain (Stellar) for transactions and record-keeping. Their Benji platform makes it accessible to retail investors with just a $20 minimum — the lowest barrier among institutional issuers. The fund has expanded to Polygon and continues to see strong retail inflows, with $400M+ in AUM.
4. The Yield: What Are You Actually Earning?
Tokenized treasury yields track the federal funds rate, since the underlying assets are short-duration US government debt. As of March 2026, the Fed funds rate is in the 4.25–4.5% range, meaning tokenized treasuries are yielding approximately 4.4–4.9% APY depending on the product and fee structure.
This compares favorably to traditional crypto alternatives: lending USDC on Aave earns ~3–4%, lending on Compound ~2–3.5%, and holding USDC in a wallet earns 0%. Tokenized treasuries offer comparable or better yield with significantly lower smart contract risk — because the underlying is US government debt, not algorithmic DeFi mechanics.
If the Federal Reserve cuts rates, tokenized treasury yields fall with them. The current 4–5% environment is historically favorable. If the Fed cuts to 1–2%, the yield advantage over traditional DeFi lending narrows considerably. Always check current rates before allocating.
5. DeFi Integration: Using T-Bills as Collateral
The most exciting frontier in tokenized treasuries isn't just holding them for yield — it's using them as collateral within DeFi. This "composability" is what makes on-chain T-bills genuinely novel versus just buying T-bills through a brokerage.
Several protocols have integrated BUIDL or USDY as accepted collateral:
6. Risks and Tradeoffs
Tokenized treasuries combine TradFi and DeFi risks. Understand both before allocating:
| Risk | Severity | Description |
|---|---|---|
| Counterparty Risk | Medium | Fund manager or custodian failure. Mitigated by regulated structures, but not zero. |
| Smart Contract Risk | Low-Medium | Bugs in the tokenization contract could freeze or misdirect funds. |
| KYC/Regulatory | Low | Regulatory changes could restrict access or require token burning. |
| Redemption Delay | Low | Most products have T+0 or T+1 redemption, but some require notice periods. |
| Interest Rate Risk | Low | Fed rate cuts reduce yield. Short-duration T-bills minimize duration risk. |
| Liquidity Risk | Medium | Secondary market liquidity varies. BUIDL has less on-chain liquidity than USDY. |
7. How to Access Tokenized Treasuries
Access depends on your investor status and how much capital you're deploying:
