BlackRock is exploring the tokenization of exchange-traded funds (ETFs) to bring real-world asset funds, including stocks, onto the blockchain, according to Bloomberg. This initiative aims to comply with regulatory requirements while leveraging blockchain for 24/7 trading, global access, and collateral use in crypto networks. Previously, BlackRock launched a tokenized money market fund, BUIDL, valued at over $2 billion, and participated in tokenized trading trials on JPMorgan's Kinexys platform. The firm is considering ETFs as a potential testing ground for these innovations.
