Uniswap Labs and Securitize add onchain trading for BlackRock’s BUIDL

Uniswap Labs and Securitize say they’ve launched a new integration that makes BlackRock’s USD Institutional Digital Liquidity Fund (BUIDL) shares available to trade onchain using UniswapX—a move aimed at giving whitelisted investors near-instant liquidity between BUIDL and USDC without trying to “retail-ify” a product that’s built for institutions.

“DeFi” for the chosen Few: BlackRock’s whitelisted playground on Uniswap

The way they’re doing it is deliberately controlled. Securitize Markets will facilitate trading for BUIDL investors who choose to participate through UniswapX’s RFQ (request-for-quote) framework, where participants can source competitive quotes from a set of whitelisted market makers (“subscribers”) and settle the swap atomically onchain via smart contracts. The release names Flowdesk, Tokka Labs, and Wintermute among the initial subscriber ecosystem. All investors using the capability are described as pre-qualified and whitelisted through Securitize.

Uniswap Labs founder and CEO Hayden Adams framed the launch as a way to create “efficient markets, better liquidity, and faster settlement” for tokenized assets. Securitize CEO Carlos Domingo pitched it as a step toward bringing traditional finance standards into DeFi—while enabling institutions to use DeFi rails for trading tokenized RWAs like BUIDL with self-custody. BlackRock’s Robert Mitchnick, Global Head of Digital Assets, called the integration “a major leap forward” for interoperability between tokenized USD yield funds and stablecoins.

One extra line in the release will get attention in the industry: BlackRock has also made a strategic investment within the Uniswap ecosystem, though no details are provided in the announcement.

Why it matters for crypto

• This is what “RWAs meet DeFi” looks like when institutions will actually touch it: RFQ-only, whitelisted participants, controlled onboarding, and onchain settlement.
• It turns a tokenized money-market fund share into something closer to programmable collateral and liquidity, by making it swappable against USDC on a 24/7 basis (for eligible investors).
• It’s a concrete example of DeFi infrastructure being used as market plumbing, not just retail trading—UniswapX is being positioned as an execution layer institutions can route through.
• The named market maker subscribers (Flowdesk, Tokka Labs, Wintermute) hint at a model where liquidity is curated, not permissionless—more TradFi-style, but onchain.

What to watch next

• Actual liquidity and spreads for BUIDL/USDC via the RFQ network—does it become a “real market” or a limited convenience rail for a small cohort?
• Whether Securitize expands the whitelisted subscriber set and which firms join—this will shape competition and pricing quality.
• If more tokenized funds follow the same pattern (RFQ + whitelisting + atomic settlement) as the default “institutional DeFi” template.
• Any further details around BlackRock’s strategic investment in the Uniswap ecosystem—size, vehicle, and what it’s meant to support.
