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. 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. 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, 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.
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.
