BlackRock has launched a groundbreaking foray into decentralized finance (DeFi) through its integration of the sBUIDL token on the Euler lending protocol on the Avalanche blockchain. This marks the first instance of a major institutional fund directly connecting with a DeFi platform, signifying a significant step forward in financial innovation. sBUIDL tokens, which represent shares of BlackRock’s tokenized U.S. Treasury fund, can now act as collateral for lending and borrowing activities within the Euler protocol. This integration is facilitated by Securitize’s sToken framework, enabling the conversion of real-world assets, such as U.S. Treasuries, into compliant on-chain tokens for seamless interaction with DeFi applications.
