Tokenized treasuries are fund units or notes, recorded as blockchain tokens, that give holders exposure to short-dated government debt — most often US Treasury bills — or to money-market funds that hold them. They have become the largest category of tokenized real-world assets because they combine a familiar, low-risk asset with on-chain benefits: 24/7 transferability, programmable collateral and fast settlement against stablecoins.
Key takeaways
- Tokenized US Treasuries are the largest RWA category; rwa.xyz data cited in mid-2026 put the category well above $10 billion, with BlackRock’s BUIDL fund alone above $2.5 billion.
- Most products are regulated funds whose units are tokens; investor eligibility is restricted.
- Yield is delivered by rising NAV, rebasing balances or periodic distributions of new tokens.
- Subscription and redemption usually follow fund settlement cycles — a natural fit for ERC-7540 vaults.
Why they took off
- Stablecoin holders wanted yield on idle cash without leaving the chain.
- DAOs and crypto treasuries needed low-risk reserves.
- Institutions wanted 24/7 collateral that settles faster than traditional funds.
- Issuers gained new distribution channels and operational efficiency.
Typical structure
| Layer | Example |
|---|---|
| Underlying | US T-bills, repos, cash |
| Vehicle | Registered or private money-market fund, or a note issuer |
| Transfer agent | Maintains the official register — increasingly the blockchain itself |
| Token | Fund unit as ERC-20-compatible permissioned token |
| Eligibility | Qualified purchasers or professional investors, KYC’d wallets |
| On/off ramps | Stablecoin or fiat subscriptions and redemptions |
How yield reaches holders
- Accumulating NAV: token price rises daily; balances stay constant (vault-share model, ERC-4626).
- Rebasing: price stays at $1; balances increase daily.
- Distribution tokens: new tokens minted to holders monthly as dividends.
Each has tax, accounting and integration consequences — rebasing tokens, for example, are harder for DeFi protocols to integrate.
Building a tokenized fund product
- Legal and regulatory setup — fund vehicle, prospectus, eligible investors, jurisdictions. See regulation guide.
- Token design — permissioned ERC-20 (ERC-3643) for units; ERC-7540 vault for async subscriptions/redemptions; ERC-7575 for multiple stablecoin entry points.
- NAV and oracles — daily NAV from the administrator published on-chain. See oracles and proof of reserve.
- Custody — custodian for T-bills; digital custody for tokens. See custody.
- Liquidity — instant redemption buffers or market-maker arrangements for 24/7 exits.
- Distribution — direct investors, platforms and DeFi integrations as collateral.
Risks to manage
- Stablecoin depeg risk on the subscription/redemption leg.
- Smart-contract and oracle risk.
- Liquidity mismatch between 24/7 token transfers and T+0/T+1 fund settlement.
- Regulatory limits on who may hold units, including in DeFi pools.
Comparing yield delivery models
| Model | Example mechanics | Integration impact | Investor view |
|---|---|---|---|
| Accumulating NAV | Token price rises daily | Easy for DeFi (like vault shares) | Value grows, balance static |
| Rebasing | Daily balance increase at $1 price | Breaks many integrations | Balance grows |
| Distribution tokens | Monthly mint of new tokens | Needs snapshot logic | Discrete “dividends” |
| Wrapped accumulating | Rebasing fund wrapped into NAV token | Adds wrapper risk | Choice of format |
A 24/7 product on a T+1 world
Tokens trade around the clock; T-bills and fund dealing do not. Bridging the gap requires:
- Instant redemption facilities funded by a liquidity buffer or a market maker, often at a small discount.
- Clear cut-off times for same-day NAV.
- Weekend and holiday policies published upfront.
- Collateral haircuts used by lenders accepting the token, reflecting redemption timing.

Frequently asked questions
No. Stablecoins aim to hold a stable value and often pay no yield to holders; tokenized treasury funds are investment products whose value reflects T-bill yields.
It depends on the product and jurisdiction. Many are restricted to qualified or professional investors.
Typically permissioned ERC-20 tokens, with ERC-7540 or ERC-4626 vault interfaces for subscriptions and redemptions.
Yes. Many exchanges, prime brokers and DeFi protocols accept them, subject to eligibility rules.
Yes; many issuers deploy on multiple chains, keeping one consolidated register through the transfer agent or a cross-chain messaging layer.
They track the underlying short-term government rates minus fees; yields change with central-bank policy.
