BlackRock's BUIDL fund, under CEO Larry Fink's direction, has rapidly grown to become the world's largest tokenized treasury fund with a market cap of US$375M in just six weeks. This marks a significant move by BlackRock into the realm of Web3 and tokenization, highlighting the growing interest of traditional finance (TradFi) in blockchain innovations. The fund's success is part of a broader trend where major financial entities like BlackRock are exploring and adopting blockchain technologies. Furthermore, a proposal has been submitted for deploying BlackRock's BUIDL fund on Arbitrum, and BlackRock along with Securitize have applied to be service providers for Arbitrum's STEP program, aimed at diversifying real-world assets (RWA), indicating a deepening commitment to integrating blockchain solutions into conventional financial practices.
