Binance Now Accepts BlackRock’s Tokenized Treasury Fund BUIDL as Collateral

BlackRock’s tokenized U.S. Treasury fund, known as BUIDL and issued through Securitize, is gaining broader adoption as Binance announces it will now accept the asset as collateral for institutional trading. The decision, revealed in a Friday press release, positions BUIDL as a flexible, yield-generating option for professional traders operating on the world’s largest crypto exchange by volume.

With this new setup, institutions can post BUIDL as off-exchange collateral, meaning the token is held with a custody partner rather than directly on Binance. This approach allows traders to maintain control of their assets, remain compliant with internal risk frameworks, and continue earning yield while actively executing trades. Binance’s head of VIP & Institutional, Catherine Chen, noted that clients have been requesting interest-bearing collateral options that deliver stability without interrupting trading activity.

Securitize is also expanding the utility of BUIDL by bringing the tokenized fund to the BNB Chain. This integration allows holders to participate in decentralized finance (DeFi) applications across the BNB ecosystem, enhancing the asset’s interoperability and reinforcing the growth of tokenized real-world assets (RWA) across blockchain networks.

The rise of tokenized RWAs—including U.S. Treasuries, credit products, and bond markets—reflects a broader shift in how investors manage liquidity on-chain. Tokenized Treasuries have become particularly popular, offering a secure place for idle capital while generating competitive yields. They are increasingly used as collateral in trading environments and as reserves for DeFi protocols seeking reliable backing.

Robbie Mitchnick, BlackRock’s global head of digital assets, emphasized that integrating BUIDL into major trading and custody platforms helps bridge traditional finance and blockchain-based markets. Since launching in March 2024, BUIDL has grown into the largest tokenized money market fund on public blockchains, amassing over $2.5 billion in assets, according to RWA.xyz.

This latest move from Binance and Securitize underscores accelerating demand for compliant, yield-bearing digital assets that bring institutional-grade financial products on-chain.
