BlackRock Brings BUIDL to BNB Chain
BlackRock first introduced BUIDL in March 2024 as its inaugural fund on a public blockchain. Now, by expanding to BNB Chain, the firm is broadening its reach to a larger community of blockchain users and investors. This launch enables more people to benefit from blockchain-based access to regulated Treasury-backed investments with daily U.S. dollar yields.
- BUIDL is backed by U.S. Treasury bills and pays a 4 percent yield.
- The fund is managed and tokenized by Securitize, which oversees fund administration and digital transaction agency services.
- The integration with BNB Chain, a network with over $7.4 billion in total value locked, increases access to compliant and programmable digital financial instruments.
Collateral Utility on Binance
One of the most notable aspects of this expansion is that BUIDL can now be used as collateral on Binance. Investors and institutions will be able to access liquidity or trading leverage without selling their holdings. This is enabled through Binance’s custody partner Ceffu and its triparty banking system, supporting secure asset-backed financial operations.
According to Carlos Domingo, CEO of Securitize:
Boosting RWA Market Momentum
The move comes at a time when tokenized real-world assets are thriving. According to RWAxyz data:
- Total RWA value on-chain has surpassed $36 billion, up over 5.9 percent in the last 30 days alone.
- The number of holders rose 10.78 percent to 537,549, and the number of issuers reached 249.
- Stablecoin market activity also grew, with value up 0.79 percent to $299.76 billion and holders climbing to 202.89 million.
These numbers signal a maturing digital financial ecosystem where investors increasingly seek compliant, transparent, and yield-bearing digital instruments that bridge traditional and decentralized finance.
Industry Voices Welcome BUIDL
Leaders across BNB Chain and BlackRock hailed the integration as a major leap for blockchain-based finance.

CoinLaw’s Takeaway
In my experience, this is a milestone not just for BlackRock or Binance, but for the entire tokenized finance industry. When a giant like BlackRock throws its weight behind blockchain, it’s no longer just an experiment. It becomes a blueprint. The fact that BUIDL is not just an investment vehicle but also serves as collateral shows how real-world assets are finally maturing into tools we can actively use, not just watch. I found this move particularly exciting because it ties together security, liquidity, and accessibility in a way few traditional financial products ever have.
