BlackRock’s tokenized money market fund, BUIDL, has officially made its entry into the decentralized finance sector. In a May 15 post on X, Euler Labs confirmed that sBUIDL, a token backed 1:1 by BlackRock’s BUIDL and issued by Securitize, is now live on the Euler protocol. This marks sBUIDL’s first direct integration with DeFi. The integration was curated by Re7 Labs and is live on Avalanche ( AVAX ). Users can now use sBUIDL as collateral to borrow USD Coin ( USDC ) or AUSD, while also earning AVAX incentives. 1/ A historic first in DeFi.

Euler’s modular architecture enables builders to combine various components to create new lending products, in contrast to traditional DeFi protocols that adhere to fixed models. Permitted markets, synthetic asset structures, and fixed-term loans are all supported by this flexibility.

The platform’s strength is its ability to support complex lending strategies, even though yield is still a major product drawing in users. Its design allows different vaults to interact seamlessly using the ERC4626 standard and Ethereum Vault Connector, creating a highly liquid network. Launched in March 2024, BlackRock’s BUIDL fund has rapidly expanded to $2.8 billion in assets, as per rwa.xyz data . The fund makes investments in U.S. Treasury bills, cash, and repos to maintain a steady $1 per token while paying dividends every day. It now spans several blockchains, including Ethereum ( ETH ), Solana ( SOL ), and Arbitrum ( ARB ). Despite its size, BUIDL’s holder base remains small, with just 73 wallets as of recent data. But its entry into DeFi points to a growing movement to connect on-chain apps with traditional finance. The sBUIDL integration pushes DeFi toward greater institutional adoption by bringing real-world assets into lending and providing a new use case for BlackRock-backed assets in decentralized markets.
