Learning Hub Tokenization and RWA
What the products sold as tokenized Treasuries are, how three of them are built, and what their own documents say about control, access and risk.

A tokenized Treasury product is usually a fund share, not a Treasury bill. The investor owns an interest in a fund; the fund owns government debt, repurchase agreements and cash; and the record of who owns the shares sits on, or is mirrored to, a blockchain (source 2).
That matters because the token changes the paperwork, not the asset. For business and allocator readers, the useful questions are the old fund questions: what legal wrapper the product uses, who may buy it, who controls the register, and what the documents say can go wrong.
This guide covers three products whose documents Le Coin read: BlackRock's BUIDL, Franklin Templeton's FOBXX and Ondo's OUSG.
Franklin Templeton's prospectus states the idea: "all Fund and shareholder records in the blockchain-integrated system are under the full and complete control of the Fund's transfer agent" (source 2). The same document contrasts its shares with native digital assets such as Bitcoin and Ether, and says the fund "will not invest in any native crypto assets of public permissionless blockchains" (source 2).
In other words, the blockchain is a filing cabinet. It can make records faster to update and easier to move between approved wallets, but the fund's rights and obligations come from its legal documents, not from code.
The register. FOBXX's record-keeping system is "a permissioned system created by the transfer agent on a public blockchain network," using smart contracts, which are programs that run on a blockchain, to hold "a whitelist of permissioned wallets" alongside administrative controls (source 2). For the Stellar network, the prospectus says this is done through token configuration (source 2).
Who can buy. FOBXX shares are bought through Franklin Templeton's Benji app or its Institutional Web Portal, and the minimum initial purchase for most accounts is $20 (source 2). BUIDL's Form D lists a $100,000 minimum investment (source 1). Ondo says OUSG is sold to "qualified purchasers," a legal category of high-net-worth investors (source 4).
The legal exemptions. BUIDL's Form D claims Rule 506(c), which lets private funds advertise if every buyer is verified as accredited, and the Investment Company Act exemption in Section 3(c)(7), for funds sold only to qualified purchasers (source 1). Ondo's docs say OUSG relies on the same two exemptions, with Ondo I LP as issuer (source 4). FOBXX instead intends to be a "Government money market fund" under Rule 2a-7, the SEC rule for money market funds (source 2).
What the fund holds. FOBXX invests at least 99.5% of its total assets in government securities, cash and repurchase agreements fully collateralized by government securities or cash, and uses amortized cost to seek a stable $1.00 share price (source 2). Ondo says OUSG invests in funds from "BlackRock, Franklin Templeton, WisdomTree, Fidelity, and others, along with bank deposits and USDC" (source 3), which makes it a fund that holds other funds.
The table shows the main split: two private funds sold only to qualified purchasers, and one registered fund open to small accounts.
| Product | Legal wrapper | Minimum | Source |
|---|---|---|---|
| BlackRock USD Institutional Digital Liquidity Fund Ltd. (BUIDL) | British Virgin Islands private fund; Rule 506(c); Section 3(c)(7) | $100,000 | 1 |
| Franklin OnChain U.S. Government Money Fund (FOBXX) | SEC-registered government money market fund | $20, most accounts | 2 |
| Ondo OUSG | Private fund (Ondo I LP); Rule 506(c); Section 3(c)(7) | $5,000 instant; $100,000 non-instant | 3, 4 |
BUIDL. The Form D amendment, signed July 23, 2026 and filed with the SEC on July 27, 2026, reports a total amount sold of $5,135,523,412, 28 investors, a first sale on March 4, 2024, and an offering amount of "Indefinite" (source 1). Total amount sold is cumulative sales reported on the filing; it is not the fund's current assets. It lists Securitize Markets, LLC as the sales-compensation recipient (source 1). BlackRock has not published an offering memorandum that Le Coin could read, so this guide does not describe BUIDL's blockchains or dividend mechanics.
FOBXX. Its summary prospectus shows a 0.15% management fee, 0.07% of other expenses, and total annual operating expenses of 0.22%, or 0.20% after a fee waiver that runs until July 31, 2027 (source 2).
OUSG. Ondo describes instant subscriptions and redemptions with a $5,000 minimum, $100,000 and $50,000 minimums for non-instant subscriptions and redemptions, and a 0.15% management fee "waived until January 1, 2027" (source 3), as of Oct. 16, 2026.
In Le Coin's view, the label "tokenized Treasuries" describes a delivery method more than an asset class. The protections an investor gets depend on the wrapper, and the wrapper is in the filing, not the token.
In Le Coin's view, size claims deserve care. The only size figure here comes from a Form D, and it measures cumulative sales, so readers comparing products should not treat it as assets under management.
