Tokenized RWAs passed $38B onchain in 2026, yet only a small share of that does anything in DeFi. Woof co-founder Dmitriy Babenko breaks down the eight layers of an RWA tokenization stack and where each one usually breaks.
Imagine you've just tokenized a fund. The contracts are audited, the token is live and the announcement went out on Tuesday.
Then a lender asks how they’re supposed to price it over the weekend. An investor in Singapore can't tell whether they're even allowed to hold it, and somebody bridges it to another chain where your KYC checks don't follow.
None of that had anything to do with the token standard. So why was the token standard the first thing everyone argued about?
Tokenized isn't the same as usable.
It's a common pattern. RWA.xyz counted $38.6B of tokenized RWAs onchain on October 1, but when Dune checked in May, only $1.7B out of $27.5B was actually being used in DeFi. For tokenized Treasuries it was around 0.5%. The token is one contract out of a dozen, and the rest of the stack decides whether anyone can use it.
Eight layers, eight ways to break
Picture one token travelling from a custodian’s books to a lending market. Every floor it passes can kill the launch.
It starts with the SPV, the custodian and the transfer agent, where the onchain balance and the legal register quietly drift apart because nobody decided which one is the truth. Next comes the chain, often an L2 picked for its grant rather than because your lenders are on it.
The token is where engineers spend their time. ERC-3643 enforces KYC and holding limits on every transfer, but only if the rules live in the contract and not in your frontend. Most real funds settle on a cycle, often T+1 or T+2, so the vault needs ERC-7540 rather than plain ERC-4626, and no lender will accept a NAV that only updates on Fridays.
Moving the asset adds two more holes: a generic bridge drops your identity registry, and a wire transfer leaves the cash a day or two behind the token..
Distribution brings in the money, yet it usually gets planned last. If nobody asked Aave Horizon or Morpho what they need until launch week, you already know which side of the 94% you’re on.
How it fits together
A tokenized fund subscription, step by step.
Take the case we see most this year: a tokenized money market or credit fund that should also work as collateral. The investor passes KYC and joins the ERC-3643 registry, then requests a deposit into an ERC-7540 vault and locks stablecoins. The administrator settles on its usual cycle, the oracle publishes the NAV, and the investor claims compliance-checked shares at that price before posting them into a lending market that reads the same feed.
Every one of those steps runs on an existing standard. The hard part is the wiring between them.
What 2026 changed
The pieces got a lot more real this year. DTCC ran its first tokenized production trades with more than 30 firms in July, and OpenZeppelin shipped an ERC-7540 implementation the same month. In September the SEC granted a five-year Innovation Exemption for tokenized securities venues, two days after the CLARITY Act failed in the Senate (Hunton).
So infrastructure risk went down and integration risk went up. You don't have to invent primitives anymore; you have to connect them without leaving gaps.
Build, buy or compose
Buying a platform gets one fund live fastest, at the cost of control over your DeFi integrations. Building from scratch almost never makes sense now, and Daniel already covered why. Most teams we talk to end up composing open standards on contracts they own, which is exactly where an engineering team that's worked inside production lending code, Compound's Comet included, earns its keep.
Whichever route you pick, answer three questions before anyone writes code: Who can hold it? Who prices it? Where will it be used?
If you know the answers, the rest is mostly engineering. If you don’t, no token standard will fix that.
