    What is BlackRock BUIDL?


    BUIDL (BlackRock USD Institutional Digital Liquidity Fund) represents a seismic shift in finance—the world's largest asset manager tokenizing U.S. Treasury securities on blockchain.


    How BUIDL Works


    BUIDL tokens represent shares in a fund holding short-term U.S. Treasuries. Each token maintains a stable $1 value while earning Treasury yields (currently ~5% APY).


    Key Features:

  1. Built on Ethereum blockchain
  2. Backed by U.S. Treasury securities
  3. Daily dividend accrual
  4. Instant 24/7 settlement

  5. Why This Matters


    For Institutions: Access to yield without leaving the blockchain ecosystem

    For DeFi: Stable, yield-bearing collateral for protocols

    For the Industry: Validation from traditional finance


    Comparing to Traditional Money Markets
