Three years ago, roughly 8% of tokenized fund assets sitting on Ethereum had any meaningful interaction with DeFi protocols. That number is now 25%.

What it means practically: the money market funds, Treasury products, and other traditional finance instruments that major institutions have been quietly tokenizing on Ethereum are no longer just sitting there looking pretty. They are being put to work as collateral, as liquidity, as productive on-chain capital inside the same DeFi ecosystem that Wall Street spent years dismissing.

The institutions showed up, and then they stayed

BlackRock’s BUIDL fund is probably the cleanest example of how this evolution looks in practice. Launched in 2024, BUIDL is a tokenized U.S. Treasury product that did not just get listed and forgotten. DeFi protocols like Ethena and Spark began using it as collateral, giving the fund a second life beyond its yield-bearing face value.

Then, early in 2026, BlackRock took another step and enabled BUIDL trading directly on Uniswap.

BlackRock is not alone. JPMorgan Asset Management introduced its tokenized money market fund JLTXX in May 2026, following an earlier fund seeded at $100M. UBS entered the market with its uMINT money market token. VanEck launched its own tokenized fund in May 2026, designed specifically to function as DeFi collateral rather than as a standalone product.

Why Ethereum and why now

Ethereum remains the dominant blockchain for tokenized real-world assets, tracked by platforms like RWA.xyz, though its share of the overall market has shown signs of softening as the ecosystem expands. Standard Chartered analysts have projected that the broader tokenized asset market could eventually reach into the trillions.

The 24/7 settlement capability that tokenization enables also matters more than it sounds. Traditional money market fund redemptions operate on business-day cycles. An on-chain version settles continuously, which means DeFi protocols can use these assets as collateral without worrying about settlement windows creating gaps in coverage.

What this means for investors and the DeFi ecosystem

For crypto-native investors, the 8% to 25% jump in DeFi utilization of tokenized assets signals something important: the yield-bearing collateral available inside DeFi is becoming higher quality. When a DeFi lending protocol accepts a BlackRock Treasury token as collateral instead of a purely speculative asset, the risk profile of that protocol changes.

Protocols that move early to integrate tokenized real-world assets as accepted collateral are positioning themselves as the on-ramps for institutional capital. Spark and Ethena’s early moves with BUIDL suggest they understood this before most.

The risks are real and worth naming. Regulatory frameworks around tokenized securities interacting with permissionless DeFi protocols remain unresolved in most jurisdictions. Smart contract risk does not disappear because BlackRock’s name is attached to the underlying asset. And the concentration of tokenized assets on a single blockchain creates a single point of systemic exposure if something goes wrong at the infrastructure layer.
