A ledger entry with a legal claim behind it

Real-world asset tokenization moves an off-chain asset — a Treasury bill, gold, a loan, a share — onto a blockchain as a transferable record. The useful way to think about it is not “a Treasury that became crypto,” but a conventional holding whose record-keeping now runs on a different ledger. The token is only as good as the legal claim attached to it.

The numbers describe a market that is real but still small in on-chain terms. On October 28, 2026, about $39.3 billion of tokenized assets sat on public blockchains, according to rwa.xyz, with tokenized U.S. Treasury funds the largest group at roughly $14.5 billion. Stablecoins, counted separately, were roughly $287 billion the same day.

What stands behind the token

A Treasury-backed token normally rests on four moving parts. An issuer — a fund or a special-purpose vehicle — owns the underlying bills. A custodian bank holds them; for BlackRock’s BUIDL fund, BNY plays that role. A transfer agent keeps the authoritative ownership list; for BUIDL it is Securitize. A whitelist then limits transfers to wallets that have passed identity checks. That last layer is why most tokenized Treasuries cannot be sent to any wallet, unlike bitcoin.

The largest products in late October 2026 were Ondo’s USDY at about $2.38 billion, Circle’s USYC at roughly $2.37 billion, and BlackRock’s BUIDL at around $2.19 billion, per rwa.xyz.

Why the yield trails a Treasury bill

Tokenization changes how an asset moves, not what it earns. In late October 2026 the average tokenized Treasury fund paid about 3.65% on an annualized seven-day basis, while the three-month Treasury bill sat near 4.15%. On a $10,000 balance that gap is only tens of dollars a year, but it is the price of round-the-clock transferability and on-chain collateral use. A holder who does not need those features would have earned more in a plain bill.

Access is a separate constraint. Most tokenized Treasury funds exclude U.S. retail investors: BUIDL is sold to qualified purchasers with a $5 million minimum at launch, Ondo’s OUSG targets qualified purchasers, and USDY is generally limited to non-U.S. persons. For now these products mainly serve crypto firms, funds, and non-U.S. buyers.

The rules are still being written

U.S. regulators have not ignored the category. A January 2026 SEC staff statement reaffirmed that a tokenized security is still a security and sorted such products into company-issued, custodial, and synthetic types with different rights. In March 2026 the SEC approved Nasdaq’s rule to trade tokenized versions of Russell 1000 stocks on the same screen as ordinary shares, with T+1 settlement. The direction of travel is to fit tokenized assets into existing securities rails rather than build a parallel regime.

Where the claim can break

The failure modes are concrete, not hypothetical. When Robinhood issued “OpenAI tokens” to European customers in mid-2025, OpenAI said they were not equity and that no transfer had been approved. On-chain private-credit protocol Goldfinch began winding down in 2026 after borrower defaults, with depositors estimating steep losses. And BlackRock itself frames BUIDL’s one-dollar target as a goal rather than a guarantee. Before buying any “asset-backed” token, check which figure a headline uses — the freely traded “distributed” total or the much larger “represented” number — then confirm the legal claim, the fees, who can redeem, and on which days.
