BlackRock Brings BUIDL Fund On-Chain to Uniswap, Takes Strategic UNI Stake

BlackRock has moved further into decentralized finance by enabling trading of its BUIDL (BlackRock USD Institutional Digital Liquidity Fund) shares on the Uniswap protocol.

At the same time, the firm disclosed a strategic investment in the Uniswap ecosystem, including an undisclosed purchase of UNI tokens.

Following the announcement, UNI rallied as much as 25%, reaching a high of $4.11, reflecting immediate market reaction to the institutional integration.

Institutional Trading Framework Built Around UniswapX

The initiative is structured as a collaboration between BlackRock, Securitize, and Uniswap Labs.

BUIDL shares will be tradable via UniswapX, an off-chain order routing system designed to aggregate liquidity before settling transactions on-chain. This architecture aims to combine decentralized execution with improved price discovery and institutional-grade routing efficiency.

Trading access is facilitated through Securitize Markets using a request-for-quote framework. Under this model, pre-qualified institutional investors can trade BUIDL against stablecoins such as USDC on a continuous basis. Securitize continues to manage investor onboarding, whitelisting, and regulatory compliance requirements.

The structure preserves compliance controls while leveraging decentralized liquidity infrastructure.

BUIDL Remains Largest Tokenized Treasury Fund

As of its 2026 integration into Uniswap’s ecosystem, BUIDL remains the largest tokenized U.S. Treasury product. The fund holds approximately $2.2 billion in total value.

Its underlying assets consist entirely of cash, U.S. Treasury bills, and repurchase agreements, positioning it as a low-risk yield vehicle within the tokenized real-world asset segment.

Each token maintains a stable $1.00 value, and dividends are distributed monthly in the form of newly issued tokens directly to investors’ wallets. This design combines stable net asset value mechanics with programmable distribution.

Structural Implication for DeFi and Institutional Markets

BlackRock’s entry into decentralized exchange infrastructure represents a structural shift rather than a symbolic gesture. By making a tokenized Treasury fund tradable on Uniswap while simultaneously acquiring UNI exposure, the firm is aligning traditional asset management with on-chain liquidity venues.

The integration suggests growing convergence between regulated financial products and decentralized execution layers. Instead of positioning DeFi and traditional finance as competing systems, the initiative demonstrates how tokenized assets can operate within both frameworks simultaneously.

The market response in UNI reflects that institutional participation in DeFi infrastructure is increasingly being interpreted as validation of its long-term viability.
