It is the first live use of a tokenization structure the SEC's staff sketched out in January — a test of whether on-chain stock trading can fit within U.S. securities law. For years, "tokenized stocks" mostly meant offshore workarounds — synthetic products that mimicked a share's price without the legal protections of owning one. Ondo Finance says it is now doing it the other way around: inside the rules. The company has started issuing tokenized versions of real U.S. securities on the **Ethereum** blockchain, beginning with **BlackRock's iShares Core S&P 500 ETF (IVV)** and shares of chipmaker **Micron Technology**, [CoinDesk reported](https://www.coindesk.com/business/2026/07/01/ondo-finance-debuts-sec-aligned-tokenized-stock-model-with-blackrock-etf-micron-shares). Crucially, the underlying shares don't move onto the blockchain. They **stay in the traditional U.S. custody chain**, while a registered intermediary mints a matching token for each one. ## How the structure works The mechanics are the whole story. The tokens are issued by **Oasis Pro TA, an SEC-registered transfer agent** that Ondo acquired as part of buying the regulated broker-dealer **Oasis Pro** [in a deal struck in 2025](https://www.theblock.co/post/361120/ondo-finance-to-acquire-us-regulated-broker-oasis-pro-for-tokenized-securities-expansion). For every real IVV or Micron share held by a regulated custodian, Oasis Pro TA creates **one "tokenized entitlement"** on Ethereum — a blockchain claim on that specific share, backed **one-for-one**. Ondo has also [partnered with **Broadridge**](https://www.broadridge.com/press-release/2026/broadridge-and-ondo-bring-shareholder-voting-capabilities-to-tokenized-securities), a major back-office financial firm, to handle **proxy voting, disclosures and shareholder communications**, so token holders get the same governance rights as ordinary shareholders. (A **transfer agent** is the registered record-keeper that tracks who owns a company's shares; **tokenization** means issuing a blockchain token that represents a real asset held in traditional custody — one token, one share.) ## Why it's built this way The design is a direct response to the U.S. regulatory picture. In **January 2026, the SEC's staff issued a statement** describing how a **custodial tokenization model** — a regulated intermediary holding the real securities and issuing blockchain tokens that represent them — could work within existing securities law, provided it preserves the usual broker-dealer, transfer-agent and custody controls. Ondo's launch is billed as the **first production use** of that framework. (A staff statement is guidance, not a formal rule, so it signals tolerance rather than blanket approval.) That distinction matters because earlier tokenized-equity products largely sat **outside** U.S. law, issued offshore to sidestep it. Building the structure around a registered transfer agent and real custody is an attempt to bring the practice onshore and make it legally durable. ## What tokenized stocks could change If the model scales, the appeal is practical. Blockchains don't close, so tokenized shares can in principle trade **around the clock**, not just during market hours. Settlement — the back-end process of finalizing a trade — can happen in **minutes** rather than the standard next-day cycle. And tokens can make it cheaper to hold or move small positions. Ondo already runs a larger version of this **outside the U.S.**, where it says it manages [more than **$1 billion** in tokenized stocks and ETFs across **over 430 securities**](https://www.coindesk.com/business/2026/07/01/ondo-finance-debuts-sec-aligned-tokenized-stock-model-with-blackrock-etf-micron-shares). One important caveat: the IVV and Micron tokens are **not yet available to U.S. investors.** This is a pilot that puts a U.S.-compliant foundation under the model, not a full retail launch at home. ## Why it matters For **crypto**, the move is part of a broader shift from speculative tokens toward **real-world assets** on-chain, with blue-chip names like a BlackRock ETF lending credibility. For **traditional finance**, it is a live test of whether blockchain rails can slot into the existing securities plumbing — custody, transfer agents, proxy voting — rather than trying to replace it. And for **regulators**, Ondo's rollout will show whether the SEC staff's January framework actually works in practice, which could determine how quickly banks, brokers and other issuers follow. Boursel gives no investment advice; the takeaway is that tokenized stocks are moving from offshore novelty toward a regulated U.S. structure — and this pilot is the first real test of whether that structure holds. ## Sources - [Ondo Finance debuts SEC-aligned tokenized stock model with BlackRock ETF, Micron shares](https://www.coindesk.com/business/2026/07/01/ondo-finance-debuts-sec-aligned-tokenized-stock-model-with-blackrock-etf-micron-shares) - [Ondo Finance to acquire US-regulated broker Oasis Pro for tokenized securities expansion](https://www.theblock.co/post/361120/ondo-finance-to-acquire-us-regulated-broker-oasis-pro-for-tokenized-securities-expansion) - [Broadridge and Ondo bring shareholder voting capabilities to tokenized securities](https://www.broadridge.com/press-release/2026/broadridge-and-ondo-bring-shareholder-voting-capabilities-to-tokenized-securities)
