BlackRock is expanding its tokenized money fund, BUIDL, to five new blockchain networks: Aptos, Arbitrum, Avalanche, Optimism, and Polygon. Initially launched on Ethereum, BUIDL invests in low-risk assets like U.S. Treasury bills. This move aims to enhance efficiency and accessibility for investors using blockchain technology. Tokenized real-world assets, such as T-Bills, are gaining traction, with a market potential of $30 trillion globally. This expansion allows BUIDL to integrate with various blockchain-based financial products, offering real-time transactions and flexible custody options.
