Key Takeaways
- Real-world assets locked in DeFi protocols reached US$18.4B in June 2026, growing 340% year-over-year.
- BlackRock’s BUIDL fund (tokenized money market) has attracted US$9.8B in assets, becoming the largest single RWA in DeFi.
- Purpose Investments launched Canada’s first tokenized government bond DeFi product in March 2026, attracting C$180M in 90 days.
- RWA tokens are increasingly used as DeFi collateral MakerDAO holds US$3.2B in RWAs backing the DAI/USDS stablecoin.
- Key risk: RWA DeFi depends on off-chain legal structures and custodians smart contracts cannot enforce off-chain rights.
In 2021, DeFi was almost entirely self-referential: crypto assets used as collateral to borrow more crypto, generating yields in governance tokens. In 2026, real-world assets tokenized versions of traditional financial instruments have become a US$18.4B category within DeFi, changing the risk profile, the yield sources, and the user base of the entire sector.
BlackRock BUIDL: The Fund That Changed the Narrative
When BlackRock launched its BUIDL fund on Ethereum in March 2024, the immediate reaction was scepticism. Two years later, with US$9.8B in assets, BUIDL has become the single largest RWA in DeFi by a wide margin. What made BUIDL successful was composability: BUIDL tokens can be used as collateral in Aave v4 and MakerDAO, meaning institutional investors can earn T-bill yields (currently 4.8% annualized) while simultaneously accessing DeFi liquidity against their holdings. This double-dipping TradFi yields with DeFi optionality has attracted sovereign wealth funds and corporate treasuries that would never have touched pure DeFi.
Canada’s First Tokenized Government Bond Product
Purpose Investments launched its tokenized Canadian Government Bond product (tCANGOV) in March 2026, backed by a portfolio of Government of Canada bonds with a weighted average maturity of approximately 2.5 years. Within 90 days, tCANGOV had attracted C$180M in assets primarily from Canadian fintech companies and crypto-native funds seeking Canadian government credit exposure without the operational overhead of traditional bond settlement.
“What surprised us was the demand from DeFi protocols themselves as treasury managers. Several DAOs and on-chain funds hold tCANGOV as part of their non-crypto reserve allocation.”

MakerDAO’s RWA Strategy
MakerDAO (now operating under the Sky brand) has been the most aggressive DeFi protocol in adopting RWAs as collateral. Of the roughly US$12.4B backing the USDS stablecoin, US$3.2B consists of RWAs primarily Ondo USDY, BlackRock BUIDL, and direct Treasury bill positions. Treasury bill yields flowing into the MakerDAO Smart Burn Engine funded US$420M in USDS buybacks in the 12 months ending May 2026.
The Structural Risk Nobody Talks About Enough
RWA DeFi has a fundamental tension: the legal world of ownership and the on-chain world of smart contract ownership are governed by completely different systems. A BUIDL token represents a legal interest in the BlackRock fund but that legal right can only be enforced through courts and custodians, not by a smart contract. If a tokenization platform’s legal wrapper fails due to insolvency, regulatory action, or contractual dispute, DeFi protocols holding those tokens face recovery through traditional legal channels. Investors in RWA-heavy DeFi protocols are taking on counterparty risk that looks like DeFi but functions like TradFi.
