Real world asset tokenization turns claims on things like Treasury bills, buildings, and private credit into tokens that trade on a blockchain, and BlackRock's entry into the space has pulled it out of crypto-niche territory and into mainstream finance.
If you've searched for what is real world asset tokenization, you've probably landed on a dozen explainers that describe the concept and never tell you how the money actually moves. So let's fix that. Tokenization takes an asset that already exists off-chain, a Treasury bond, an apartment building, a slice of private credit, and issues a digital token that represents legal or economic ownership of it. The token lives on a blockchain. The asset does not. That gap between the two is where almost everything interesting, and almost everything risky, happens.
BlackRock's BUIDL fund is the clearest real-world case study. Launched in March 2024 on Ethereum, BUIDL lets institutional investors hold a token backed by cash, U.S. Treasury bills, and repurchase agreements. According to data from rwa.xyz, BUIDL had grown to roughly $2.9 billion in assets by mid-2025, making it one of the largest tokenized Treasury products anywhere. Franklin Templeton runs a similar product, its OnChain U.S. Government Money Fund, which trades under the ticker BENJI and settles on public chains including Stellar and Polygon. Neither of these is a crypto experiment. They're regulated funds with a blockchain bolted onto the settlement layer.
The mechanics run through three layers, and skipping any one of them is where projects fail. First, there's the legal wrapper. Someone has to actually own the underlying asset, usually a special purpose vehicle or a fund structure, and that entity has to promise token holders a claim on it. Ondo Finance, for instance, structures its OUSG token as a claim on shares of BlackRock's own short-term Treasury ETF, held through a regulated custodian. Without that legal layer, a token is just a picture of an asset, not a claim on one.
Second, there's the smart contract layer, the code that mints, burns, and transfers tokens, and enforces who's allowed to hold them. Most institutional RWA tokens use permissioned contracts, meaning only wallets that have passed KYC checks with the issuer can hold or trade them. That's a deliberate design choice, not a technical limitation, and it's the opposite of the anonymous, anyone-can-hold model that made Bitcoin popular in the first place.
Third, there's the oracle and reporting layer, which feeds real-world data, interest accrual, asset valuations, redemption requests, back onto the chain so the token price actually reflects what's happening to the underlying asset. Get this wrong and you get a token that trades at a price disconnected from the thing it's supposed to represent, which is exactly what happened to several early stablecoin-adjacent projects before over-collateralization and transparent reserve reporting became standard practice.
Tokenized Real Estate Investing Looks Nothing Like Tokenized Treasuries
Here's where people get tripped up. Tokenized real estate investing gets pitched with the same language as tokenized Treasuries, but the two have almost nothing in common as investments. A Treasury bill is fungible, liquid, and has a government backing repayment. A building is illiquid, unique, and its value depends on a local market, a management company, and whether the roof needs replacing. Tokenizing the building doesn't fix any of that. It just changes who can buy a fraction of it and how fast that fraction can, in theory, change hands.
RealT is the most cited example here. It tokenizes fractional ownership of single-family rental properties in cities like Detroit, letting investors buy in for as little as $50 and receive rental income in stablecoins. That's a genuine access improvement for someone who couldn't otherwise buy a $150,000 house. But the secondary market for RealT tokens is thin, and thin markets mean you can hold a token that says you own 1/500th of a Detroit duplex with no easy way to sell it back at a fair price. Tokenization solved the access problem. It didn't solve the liquidity problem, because liquidity comes from buyers actually showing up, not from a token standard.
Frankly, this is the gap most RWA marketing glosses over. A blockchain can make an asset divisible and transferable in theory. It cannot manufacture a buyer on the other side of the trade.
Where Tokenized Treasury Bonds Fit In
Tokenized treasury bonds are the category actually working at scale right now, and the reason is straightforward: Treasuries are already liquid, already trusted, and already priced efficiently off-chain. Tokenizing them adds speed and programmability without asking investors to trust a new kind of asset, just a new wrapper around a familiar one. According to a report from the Boston Consulting Group and ADDX, the broader tokenized asset market could reach $16 trillion by 2030, and short-duration government debt is the segment analysts expect to lead that growth, precisely because it's the easiest asset to tokenize honestly.
That's also why regulators have been comparatively comfortable with this corner of RWA. The Securities and Exchange Commission has allowed BUIDL and similar funds to register through conventional fund structures, treating the blockchain as a settlement rail rather than a new asset class requiring new rules. Tokenized real estate and private credit haven't gotten the same clarity, and that regulatory gap is a big part of why Treasury products dominate the current market while property and credit tokenization remain smaller and more experimental.
How Retail Investors Can Actually Get In
For most retail investors, direct access to products like BUIDL isn't realistic. It's built for institutions and requires minimum investments that put it out of reach for individuals. What's actually accessible is Ondo's OUSG and USDY tokens, which wrap institutional Treasury exposure into products retail investors can buy through Ondo's platform, and fractional real estate platforms like RealT or Lofty, which list properties with entry points as low as $50. Securitize, the transfer agent behind several tokenized funds including BUIDL, also runs its own investor portal for accredited investors looking for direct exposure.
Before putting money into any of these, check three things: who actually holds the underlying asset, whether the token is redeemable for cash or the asset itself and on what schedule, and whether a regulated custodian or transfer agent sits between you and the issuer. If a platform can't answer those questions clearly, the token isn't really backed by anything you can enforce a claim on. That's not a hypothetical risk. It's the exact failure mode that has sunk several smaller RWA projects that promised yield without ever nailing down the legal structure underneath it.
Tokenization won't replace the plumbing of traditional finance overnight, and anyone selling it as an instant fix for illiquid markets is skipping the hard part. But for an asset that's already liquid and already trusted, like a three-month Treasury bill, putting it on a blockchain genuinely does make it settle faster and trade more flexibly. That's a real improvement, and it's the one part of this story that's already working.
