BlackRock USD Institutional Digital Liquidity Fund

What is BUIDL?

BUIDL (BlackRock USD Institutional Digital Liquidity Fund) represents a watershed moment for tokenized real-world assets: the world's largest asset manager bringing institutional-grade money market exposure on-chain. Launched in March 2024 through a partnership with Securitize, BUIDL offers qualified institutional investors direct access to a fund invested in US Treasury bills, repurchase agreements, and cash, with the unique ability to transfer ownership 24/7 via blockchain rails.

With BlackRock managing over $10 trillion in assets globally, BUIDL signals the institutional legitimacy of tokenized securities. The fund quickly became one of the largest tokenized treasury products, attracting hundreds of millions in assets from crypto-native institutions, DAOs, and traditional finance entities seeking the efficiency of blockchain settlement combined with BlackRock's asset management expertise.

BUIDL is designed specifically for institutional and qualified purchaser clients, featuring a $5 million minimum investment and operating under traditional securities regulations. Unlike DeFi-native products, BUIDL offers the familiar structure of a regulated money market fund with the added benefits of instant transferability and 24/7 operation that blockchain technology enables.

How BUIDL Works

BUIDL operates as a traditional money market fund with blockchain-based share issuance and transfer:

BUIDL vs Other Tokenized Treasuries

Why BUIDL Matters

BUIDL represents several firsts:

• BNY Mellon custody: Traditional finance infrastructure on-chain
• Institutional on-ramp: Bridge for TradFi allocation to blockchain

Frequently Asked Questions

BUIDL is limited to qualified purchasers under SEC regulations, typically institutions, funds, and high-net-worth entities meeting specific financial thresholds. The $5M minimum further restricts to institutional-scale investors.

BUIDL IS a money market fund, but with tokenized shares on Ethereum. The difference is transfer capability: BUIDL shares move 24/7 on blockchain rather than through traditional transfer agent processes.

Currently, BUIDL's permissioned nature limits DeFi integration. Only whitelisted addresses can hold BUIDL, restricting use in permissionless protocols. Institutional DeFi platforms may support BUIDL collateral.

BUIDL shares exist in BlackRock's traditional fund registry regardless of blockchain status. Ethereum outages affect transfer capability but not underlying fund value or investor rights.

Like traditional money market funds, BUIDL targets but doesn't guarantee $1.00 NAV. The fund structure and Treasury backing make deviation extremely unlikely under normal conditions.
