BlackRock and tokenization pioneer Securitize are making a significant move into decentralized finance (DeFi) by enabling direct on-chain trading of BlackRock’s tokenized Treasury fund — known as BUIDL — on Uniswap, one of the world’s largest decentralized exchanges. The news sent the UNI token up nearly 20 % in early trading as markets reacted to the integration.
The integration marks the first time that BlackRock’s regulated tokenized fund will be accessible natively on a permissionless DeFi protocol, allowing qualified investors and traders to trade BUIDL shares directly through Uniswap’s automated market maker (AMM) liquidity pools without intermediaries.
BlackRock’s USD Institutional Digital Liquidity Fund (BUIDL) — a tokenized version of a traditional money-market fund backed by highly liquid, low-risk assets like U.S. Treasuries and repurchase agreements — was originally launched on public blockchains through a partnership with Securitize. The fund brings a regulated, real-world asset (RWA) onto distributed ledgers, offering transparency and friction-less transfer capabilities.
By enabling direct on-chain trading on Uniswap, investors can now:
Swap BUIDL tokens directly against other assets on the DeFi exchange
Tap decentralized liquidity rather than centralized order books
Potentially access improved capital efficiency and 24/7 settlement
Uniswap’s automated market maker design — where liquidity providers contribute tokens in pairs and pricing is determined algorithmically — allows users to trade tokenized assets like BUIDL without relying on traditional intermediaries.
The integration brings a major mainstream financial institution — BlackRock — further into the DeFi stack, highlighting how tokenized real-world assets are beginning to blend with decentralized protocols traditionally used for purely crypto native trading. Analysts see this as a milestone in bringing institutional capital and tradable, regulated asset classes onto platforms historically dominated by volatility-focused tokens and speculative markets.
Securitize, the technology and compliance partner behind BUIDL, has been a key driver in this evolution. The firm operates regulated token issuance infrastructure for public blockchain assets and has partnered with BlackRock on multiple fronts to bridge traditional asset management with crypto rails.
Institutional and retail investors alike likely viewed this as a validation of DeFi’s capacity to handle serious capital, liquidity and real-world asset workflows. Uniswap’s rise in price following the announcement reflects heightened enthusiasm around on-chain fund trading and the institutionalization of decentralized markets.
