A tokenized Treasury is an interest in a vehicle holding short dated US government debt, where the ownership record is kept on a blockchain rather than only in a transfer agent's database. The holder owns a claim on the fund or the issuing entity, not the bills themselves; a custodian holds those. SEC staff have stated the position directly: a tokenized security is still a security, and the format in which it is issued does not change how the federal securities laws apply.
The yield is the product and the wrapper is the risk. Two tokens can both be marketed as tokenized Treasuries and give the holder entirely different things: a registered fund interest, an offshore SPV note, or a third party's synthetic exposure carrying no claim on the fund at all.

What the product is once you take the token off
Strip the token away and you have a familiar instrument: a pooled vehicle holding Treasury bills, repo, or both, that publishes a net asset value and lets holders subscribe and redeem. Tokenization changes where the ownership record lives and how quickly a transfer settles. It does not change what backs the position or what the position pays.
US staff put the definition on the record in a January 2026 statement from the Divisions of Corporation Finance, Investment Management, and Trading and Markets. A tokenized security is "a financial instrument enumerated in the definition of 'security' under the federal securities laws that is formatted as or represented by a crypto asset, where the record of ownership is maintained in whole or in part on or through one or more crypto networks."1 The same statement is direct about the consequence: "the format in which a security is issued" does not affect application of the federal securities laws.1
The statement also splits the market in two: securities tokenized by or on behalf of their own issuer, and securities tokenized by third parties unaffiliated with that issuer.1 Which side of that line a product sits on decides what the holder owns, and it is not visible from the ticker. It gets its own section below.
The wrapper and the transfer agent do the real work
The wrapper is the entity issuing the claim, and it selects the regime everything else runs under. BlackRock's BUIDL is a British Virgin Islands entity offered under the US Securities Act Regulation D exemption, custodied at Bank of New York Mellon, with Securitize as transfer agent and PricewaterhouseCoopers as auditor.2 Four named counterparties, four failure surfaces, and only one of them is the token contract.
The transfer agent is the role founders underweight. It maintains the register of who holds the claim, runs the identity checks, and is the party minting and burning. In a tokenized structure part of that register is onchain, which means the transfer agent's whitelist is the transfer restriction. Send a token to an address the transfer agent has not approved and the transfer does not settle. That is your distribution surface, and it is decided in the wrapper rather than in Solidity.
The registered fund route is a different animal entirely. A money market fund registered under the Investment Company Act runs to Rule 2a-7: no instrument with a remaining maturity over 397 calendar days, a dollar weighted average portfolio maturity at or under 60 days, a weighted average life at or under 120 days, at least 25 percent of total assets in daily liquid assets and at least 50 percent in weekly liquid assets, with board notice within one business day if daily liquid assets fall below 12.5 percent.3 A Reg D vehicle holding the same bills carries none of that by operation of law. If the offering documents do not impose it, nothing does.
Named issuers, with the figures dated
Read on 3 August 2026: Circle's USYC at $3,005,660,310, BlackRock's BUIDL at $2,673,461,059, Ondo's USDY at $2,152,649,158, and Franklin Templeton's iBENJI at $1,731,124,250.24 Roughly $9.56 billion across four products, on a dashboard recomputing continuously.
Treat every one of those as a point in time read rather than a market constant. BUIDL's figure was up close to 20 percent against the prior thirty days at the moment it was pulled.2 Anything moving that fast is a snapshot, and quoting it six months later without the date attached is how a deck quietly becomes wrong.
The distribution is the more interesting fact. First place to fourth is a spread of under 1.8 times, which is not what brand recognition alone would predict. On this dashboard's accounting no issuer owns the category, and in our view what separates these products is the wrapper, the eligible holder set and the redemption terms rather than the name on the fund.
How the yield reaches the holder
Two designs, and the choice decides which venues your token can live in. In the first, net asset value per token appreciates and the unit count never moves. Superstate's USTB is the live example: a net asset value of $11.16 per token against a total asset value of $757,757,779, with a 7 day APY of 3.01 percent, read on 3 August 2026.5 The holder's balance stays where they bought it and the price of each unit carries the return.
In the second, NAV is pinned near $1.00 and the unit count grows as income accrues. It reads like a bank balance and it prices more simply. It also breaks any integration assuming a balance changes only on transfer. Across the RWA structures we have reviewed, this is the most common late discovery: the accrual design was picked for the fund's operational convenience, then collided with a lending market that could not account for it.
Either way the token is not manufacturing the yield. Short dated government paper is, less the management fee, custody, transfer agent and audit. If a tokenized Treasury product is quoting a rate materially above the bill curve, the difference is coming from somewhere other than bills, and finding out where is the diligence, not a detail.
Redemption windows and the hours the desk is shut
The token trades whenever the chain is producing blocks. The primary market does not. BUIDL's documented lifecycle runs on clock times: funds wired and confirmed by 2:30 PM ET result in tokens minted to a whitelisted wallet, and for redemption the tokens must reach the transfer agent's redemption wallet by 3:00 PM ET before the USD or USDC wire is instructed and the matching tokens burned.2
Everything outside those windows is secondary market only. A holder selling at 3 a.m. on a Sunday is selling to whoever is there, at whatever that person will pay, with no route back to NAV until the next cutoff. That gap is the arbitrage band, and its width is set by how long the redemption channel stays closed and how much it costs to use when it opens.
Underneath the cutoff sits the settlement of the bills themselves, which clears on the government securities cycle rather than the chain's. A redemption promise faster than the underlying settles is a funding mismatch, met from a cash buffer, from a credit line, or not at all. Ask which, in writing, and ask what the answer becomes in a week when everyone asks at once.
Not a stablecoin, and the difference is structural
A payment stablecoin is engineered to hold one unit of value and pays the holder nothing. A tokenized Treasury is designed for the value to move, because the return is the point. Everything else follows from that one difference.
The regulatory route splits on the same line. In the EU an e-money token sits inside MiCA, and Article 50 prohibits its issuer, and any crypto-asset service provider handling it, from granting interest, with any benefit tied to how long a holder holds treated as interest.6 A tokenized fund unit is not in MiCA at all: Article 2(4) removes crypto-assets qualifying as financial instruments, deposits or funds from the Regulation's scope, leaving them under MiFID II and existing EU securities law.6
The practical consequence in Europe is that the payment instrument and the yield bearing instrument are two different tokens under two different regimes. A founder describing a euro or dollar unit that also pays a rate is describing two products, and the second one comes with a prospectus and an eligible holder set.
Third party wrappers change what you own
The staff statement names the models. Under a custodial model, a third party holds the underlying security and issues a crypto asset evidencing the holder's interest in it, such as a tokenized security entitlement.1 Under a synthetic model, the third party issues its own security giving exposure to the referenced one: a linked security, or a security based swap.
The staff is blunt about the second. A linked security "is not an obligation of the issuer of the referenced security and confers no rights or benefits from the issuer of the referenced security," and holders of a third party token "may be exposed to risks with respect to the third party, such as bankruptcy, to which a holder of the underlying security would not necessarily be exposed."1
Now read that against a product page saying "tokenized Treasuries." Three structures, three different answers to the question of who owes you money, and the ticker will not distinguish them. This is the first question to ask about any such product, not a footnote at the end of the diligence.
What to settle before issuing one
Five decisions, before any contract work. Which entity issues the claim, in which jurisdiction, under which exemption or registration. Who custodies the bills and who acts as transfer agent, and whether those are genuinely separate parties. Whether the return accrues into NAV or into unit count, checked against a written list of the venues you need to reach. What the subscription and redemption windows are, in clock time, and what backstops them under stress. And whether you are issuing the security or wrapping somebody else's, because that changes what you owe and to whom.
Custody and proof of reserves are separate entries in this glossary and both sit underneath this one. A tokenized Treasury with an immaculate wrapper and a custodian nobody diligenced is not a safer instrument than an unwrapped one. It is a slower failure with better documentation.
Whether a specific tokenized Treasury product is a security in a given jurisdiction, and whether a given structure achieves the segregation its materials describe, is fact-specific and belongs with your counsel. This page is reference material for design work. It is not legal advice, and nothing here is a recommendation to buy, sell or hold any asset.
Common questions
What is a tokenized Treasury?
A tokenized Treasury is an interest in a fund or special purpose vehicle holding short dated US government debt, with the ownership record maintained on a blockchain. The holder owns a claim on the vehicle rather than the bills, which sit with a custodian. SEC staff define a tokenized security as a security formatted as a crypto asset, where ownership is recorded in whole or part on crypto networks.1
Are tokenized Treasuries securities?
In the US, tokenizing a security does not change its legal character. SEC staff have stated that the format in which a security is issued does not affect application of the federal securities laws.1 In the EU, crypto-assets qualifying as financial instruments or funds are outside MiCA's scope entirely and remain under existing securities law.6 Whether a specific product is a security in a specific jurisdiction is a question for counsel.
How is a tokenized Treasury different from a stablecoin?
A payment stablecoin holds one unit of value and pays the holder nothing. A tokenized Treasury is built for the value to move, because the return is the product. The regimes split the same way: in the EU, MiCA Article 50 prohibits granting interest on e-money tokens, while a tokenized fund unit sits outside MiCA under existing securities law.6
Can you redeem a tokenized Treasury at any time?
Generally no. Redemption runs on the issuer's clock, not the chain's. BUIDL's documented process requires tokens to reach the transfer agent's redemption wallet by 3:00 PM ET before the wire is instructed and the tokens burned.2 Outside that window the only exit is the secondary market at whatever price is available, with no route back to net asset value until the next cutoff.
Who holds the Treasury bills behind the token?
A regulated custodian, and it should be a different party from the one minting and burning tokens. In BlackRock's BUIDL, Bank of New York Mellon custodies the assets while Securitize acts as transfer agent, with PricewaterhouseCoopers as auditor.2 Keeping the roles apart is what makes any reporting on reserves meaningful, because the party holding the assets is not the party reporting on them.
