Tokenised treasuries are the gateway drug for institutional crypto adoption. When the world’s largest asset manager puts US government bonds on Ethereum, that’s not some crypto experiment – it’s a clear statement about where financial infrastructure is heading. And if you’re still treating it as a curiosity, you’re behind.
Key Takeaway
BlackRock’s BUIDL fund – tokenising US Treasury bills on Ethereum – signals institutional validation of tokenised treasuries as a legitimate asset class, compressing the adoption timeline for other institutional tokenisation use cases and establishing Ethereum as the primary institutional blockchain infrastructure layer.
The numbers tell the story. On-chain treasuries crossed the billion-dollar mark and kept going. And the players involved aren’t DeFi degens – they’re BlackRock, Franklin Templeton, names managing trillions in traditional markets. Names that don’t do experiments.
Let me break down what’s actually happening here, why it matters, and what it means for you.

What Are Tokenized Treasuries?
Tokenised treasuries are blockchain-based tokens that represent ownership in US Treasury bills, bonds, or money market funds holding government securities. When you hold a tokenised T-bill, you’re economically exposed to the same asset that underpins the global financial system – just on-chain rather than tucked inside a brokerage account.
The underlying assets are real. Custodians are regulated. The yield comes from the US government’s obligation to pay interest on its own debt. Nothing exotic about the economics – the innovation is entirely in the infrastructure layer.
How Do Tokenized T-Bills Actually Work?
The mechanics are fairly straightforward once you strip away the jargon:
- An asset manager creates a fund holding short-duration US Treasuries or money market instruments
- A tokenisation partner (like Securitize) mints tokens representing shares in that fund
- Investors purchase tokens after completing KYC/AML verification
- Yield accrues daily and is either distributed or reflected in the token price
- Redemption happens through the issuer – you return tokens and receive stablecoins or fiat
The yield you earn matches the prevailing US Treasury rate, minus management fees. At time of writing, that’s been sitting somewhere in the 4–5% range. Not spectacular on its own, but that’s the point – risk-free rate yield, on-chain. For DeFi protocols hunting for sustainable returns, that matters enormously.
The Key Players
BlackRock BUIDL
BlackRock’s USD Institutional Digital Liquidity Fund – branded BUIDL – launched in March 2024 and immediately shifted the whole conversation.
What makes BUIDL significant:
- Issued by BlackRock – the firm managing north of $10 trillion in assets
- Built on Ethereum via Securitize as transfer agent
- $1 per token NAV with daily yield accrual
- Minimum investment of $100,000 – institutions only, not retail
- Already expanded to multiple chains including Avalanche, Polygon, and others
BUIDL didn’t just validate tokenised treasuries. It validated the entire RWA thesis. Once BlackRock builds something, the “too risky/weird/unproven” argument falls apart pretty quickly.
Franklin Templeton BENJI (FOBXX)
Franklin Templeton was actually first to market – a fact that gets buried whenever BlackRock dominates the headlines. Their Franklin OnChain US Government Money Fund (FOBXX) launched on Stellar back in 2021 and later expanded to Polygon.
Key details:
- First registered US mutual fund to use a public blockchain for transaction processing
- Shares are represented as BENJI tokens
- Lower minimum than BUIDL – accessible to a broader investor base
- Has been quietly operational for years while others were still drawing up plans
Franklin Templeton deserves more credit than they get. While everyone else was talking about tokenisation, they were actually doing it.
Ondo Finance
Ondo is the crypto-native challenger in this space. Their OUSG (Ondo Short-Term US Government Bond Fund) gives DeFi-native users access to treasury yield without going through a traditional asset manager.
Why Ondo matters:
- Bridges TradFi yield into DeFi in a way institutions like BlackRock don’t (yet)
- OUSG can be used as collateral in certain DeFi protocols
- Also offers USDY – a yield-bearing stablecoin alternative backed by treasuries
- Lower barriers to entry than the institutional products
Ondo sits at the intersection of TradFi assets and DeFi composability. That’s a genuinely powerful position to be in right now.
Other Notable Players
- Mountain Protocol (USDM) – yield-bearing stablecoin backed by T-bills
- Backed Finance (bIB01) – tokenised short-term treasury ETF aimed at non-US investors
- Matrixdock (STBT) – short-term treasury-backed token
- OpenEden – tokenised T-bill vault
Why Did Institutions Start With Treasuries?
This wasn’t random. Treasuries make perfect sense as the starting point for a few clear reasons.
Low risk profile. US Treasuries are the benchmark “risk-free” asset. By tokenising the safest possible asset class, issuers minimise the risk variables and let the infrastructure prove itself without the asset itself causing headaches.
Simple to understand. You buy a bond, you get interest, you get your principal back. No rental income complexities, no credit underwriting, no commodity storage. Clean, simple yield.
Regulatory familiarity. Regulators understand treasuries already. They’re not being asked to evaluate a novel asset – just a novel delivery mechanism for a familiar one.
Massive demand for on-chain yield. DeFi protocols need yield sources that aren’t built on token emissions. Treasury yield is the most credible source available. Read more on this in RWA Yield vs DeFi Yield.
Collateral potential. Once tokenised treasuries become accepted as collateral across DeFi, the implications get genuinely interesting. Imagine posting T-bill tokens as collateral for a loan – earning yield on your collateral while borrowing against it simultaneously.
What You Actually Get When You Hold a Treasury Token
Let’s be precise about this, because it matters more than most people realise:
- You don’t hold a US Treasury bond directly. You hold a token representing a share in a fund that holds treasuries.
- Your legal claim is against the fund, not against the US government itself.
- Yield is net of fees – typically 0.15–0.50% management fee depending on the issuer.
- Redemption is through the issuer – you can’t just sell on Uniswap. Some have secondary market liquidity, but primary redemption goes through the fund.
- KYC is required for virtually all legitimate treasury token products.
That’s not a criticism – just reality. Understanding the structure helps you evaluate the actual risk profile clearly.
The Bigger Signal: What Tokenized Treasuries Tell Us
Here’s what I think most people miss about this whole trend.
It’s not about the yield. You can get 4–5% from a savings account or money market fund without touching crypto. The yield itself isn’t the innovation.
It’s about the infrastructure. BlackRock didn’t tokenise treasuries because blockchain makes bonds better. They did it because blockchain makes the plumbing better – settlement, distribution, record-keeping, and eventually, composability with the rest of the system.
It’s a Trojan horse. Once institutions have tokenised assets on-chain, the logical next step is using them within DeFi infrastructure. That’s where the composability thesis gets genuinely exciting.
It normalises crypto rails. Every institution that uses Ethereum for settlement is one more institution that sees blockchain as infrastructure rather than speculation. That shift in framing matters enormously.
The Oracle Connection
Tokenised treasuries might look simple, but they still depend on off-chain data feeds for NAV pricing, interest rate updates, and fund reporting. This creates an oracle dependency that’s worth understanding, even if it’s smaller here than in other asset classes.
For treasuries, the oracle risk is relatively low because the underlying data – T-bill rates, NAV calculations – is standardised and widely available from multiple sources. But it’s not zero, and that’s always worth remembering.
What’s Next for On-Chain Treasuries
The direction of travel is fairly clear from here:
- Multi-chain expansion – BUIDL is already on multiple chains. Others will follow. The asset goes where the liquidity is.
- DeFi collateral integration – the real unlock. When you can post BUIDL tokens as collateral on Aave or Morpho, the demand dynamic shifts dramatically.
- Retail access – current minimums are too high for individual investors. That will change as competition intensifies.
- Competition driving fees lower – more issuers means tighter spreads and lower management fees across the board.
- Longer duration products – today it’s T-bills. Eventually it’ll be 10-year bonds and diversified fixed income portfolios.

FAQ
What is BlackRock’s BUIDL fund?
BlackRock’s BUIDL (USD Institutional Digital Liquidity Fund) is a tokenised money market fund on Ethereum that invests in US Treasury bills and repurchase agreements. Tokens maintain a $1 NAV with daily yield accrual. It’s issued through Securitize and requires a $100,000 minimum investment.
How much yield do tokenized treasuries pay?
Tokenised treasury products yield roughly 4–5% annually (as of early 2026), matching prevailing US Treasury rates minus management fees that typically run from 0.15% to 0.50%. The yield comes directly from US government interest payments on the underlying securities.
Are tokenized T-bills safe?
Tokenised T-bills carry minimal credit risk because the underlying assets are US government obligations. However, they do carry smart contract risk, counterparty risk (the fund manager and custodian), and regulatory risk. The credit quality of the underlying asset is excellent – the wrapper adds its own risk layers on top.
Can I use tokenized treasuries as DeFi collateral?
Some protocols are beginning to accept tokenised treasury tokens as collateral, but adoption is still relatively limited. This is expected to expand significantly as the category matures. Earning yield on collateral while borrowing against it simultaneously is one of the most compelling use cases going forward.
What is the difference between BUIDL, BENJI, and OUSG?
BUIDL (BlackRock) and BENJI (Franklin Templeton) are traditional asset manager products brought on-chain – institutional-grade with higher minimums. OUSG (Ondo Finance) is crypto-native, designed for DeFi integration with lower barriers to entry. All three give exposure to short-term US government securities, but differ in accessibility, composability, and fee structure.

Frequently Asked Questions
What is BlackRock’s tokenised treasury fund and why does it matter?
BlackRock’s BUIDL (BlackRock USD Institutional Digital Liquidity) fund tokenises US Treasury bills on the Ethereum blockchain, allowing investors to hold on-chain representations of government securities that earn real yield. Its significance is in the institutional validation – when the world’s largest asset manager places government bonds on blockchain infrastructure, it signals the technology is production-ready for regulated financial assets.
How does tokenising treasuries benefit institutional investors?
Tokenised treasuries offer: instant 24/7 settlement compared to T+2 in traditional markets, programmable transfer and collateral management, composability with DeFi protocols for additional capital efficiency, and reduced operational overhead from automated yield distribution. For institutional treasuries managing large cash positions, these efficiencies compound significantly at scale.
What does BlackRock’s move mean for other RWA categories?
BlackRock’s entry into tokenised treasuries accelerates the entire RWA ecosystem by resolving institutional risk tolerance questions, establishing a precedent for regulatory treatment, and demonstrating a viable operational model. Expect to see accelerated tokenisation of other fixed-income instruments, then equity-linked products, following the institutional pathway BlackRock has established.
