BlackRock’s tokenized money market fund BUIDL is expanding its presence and is now available in the BNB Chain blockchain ecosystem. This marks another important milestone in the development of the real-world asset (RWA) tokenization market and its integration into DeFi infrastructure.
What Is BUIDL?
The BlackRock USD Institutional Digital Liquidity Fund (BUIDL) is issued via the Securitize platform and is already among the largest products in the RWA segment. Its market capitalization is estimated at around $2.5 billion.
The fund’s assets are allocated to:
- U.S. dollars
- Short-term U.S. Treasury bills
- Repo agreements
This structure gives investors access to traditional money market yields in an on-chain format.
BUIDL was initially launched on Ethereum and later became available on several other blockchains:
- L1: Aptos, Avalanche, Solana
- L2 solutions: Arbitrum, Polygon, Optimism
Now BNB Chain has joined this list.
Why Integrate BUIDL with BNB Chain?
Support for BNB Chain unlocks new opportunities for BUIDL holders:
- use of the token in DeFi applications within the BNB Chain ecosystem
- improved operational cross-chain compatibility of the asset
- more flexible liquidity management across different networks
At the same time, the fund can now be used as over-the-counter collateral for trading on Binance. Institutional market participants will be able to keep their tokens with a custodial partner off-exchange, maintain exposure to yield-bearing strategies, and still deploy the tokens as collateral.
Head of Digital Assets at BlackRock, Robbie Mitchnick, emphasized that using BUIDL as collateral within leading digital market infrastructure helps bring core elements of traditional finance (TradFi) into on-chain finance.
RWA Market: Scale and Potential
Interest in tokenizing real-world assets is growing rapidly. According to analysts at Standard Chartered, by 2028 the total market value of RWA tokens (excluding stablecoins) could reach $2 trillion. Today, according to RWA.xyz, that figure is around $36 billion.
At the same time, the market capitalization of stablecoins surpassed $300 billion about two months ago, demonstrating steady demand for on-chain instruments tied to real assets or fiat currencies.
The Role of BNB Chain in Asset Tokenization
BNB Chain is gradually establishing itself as one of the key infrastructure platforms for RWA projects. Back in October, a subsidiary of the Chinese bank China Merchants Bank tokenized a money market fund with $3.8 billion in assets on BNB Chain.
Against this backdrop, the arrival of BUIDL in the BNB Chain ecosystem further strengthens its position as an important platform for tokenizing traditional financial instruments and integrating them into DeFi.
Bottom Line
The integration of BlackRock’s BUIDL with BNB Chain:
- expands opportunities for both institutional and retail investors
- reinforces the bridge between TradFi and DeFi
- supports further growth and maturation of the RWA market
Amid the global trend toward asset tokenization, moves like this from major players such as BlackRock are becoming key drivers of on-chain finance development.
