BlackRock Enters DeFi: World's Largest Asset Manager Lists $2.2B Tokenized Treasury Fund BUIDL on Uniswap

On February 11, 2026, BlackRock integrated its $2.2–2.4 billion BUIDL fund with UniswapX, marking the asset manager's first direct entry into decentralized finance. The BUIDL fund, which is 100% backed by U.S. Treasuries and cash equivalents, now utilizes Uniswap's RFQ protocol to facilitate institutional-grade, on-chain trading. Market makers such as Wintermute and Flowdesk provide liquidity for these transactions, which remain restricted to KYC-verified institutional investors. This development is significant as it represents the first time a major traditional finance institution has utilized DeFi rails for a flagship yield-bearing product. Furthermore, BlackRock disclosed a strategic investment in the UNI governance token, signaling a deeper commitment to the Uniswap ecosystem. This move aligns with CEO Larry Fink's vision of tokenization as the next evolution of global market infrastructure. By leveraging Ethereum, which currently hosts approximately 65% of all tokenized real-world assets, BlackRock is setting a precedent for institutional adoption of public blockchain rails. This integration validates the use of DeFi infrastructure for regulated, high-value financial assets while bridging the gap between traditional fixed-income products and on-chain liquidity.
