BlackRock’s tokenized fund BUIDL has taken a monumental leap in its institutional adoption, consolidating the trend of real-world assets (RWA). In a joint statement this Friday, Binance, the world’s largest cryptocurrency exchange by volume, announced that BUIDL will be accepted as collateral for institutional trading.
Thanks to this advancement, traders will be able to use BUIDL under an off-exchange custody model. In practice, this means institutions can hold their yield-generating assets in an associated custody account instead of depositing them directly on the exchange, improving flexibility, risk management, and regulatory compliance.
Catherine Chen, Head of VIP & Institutional at Binance, noted that this inclusion responds directly to client demand for “more interest-bearing stable assets” to support their active trading operations.
The impact of this listing is profound and validates the RWA narrative that has dominated 2025. BUIDL is no minor asset; since its launch in March 2024, it has grown to become the largest tokenized money market fund on public blockchains, accumulating $2.5 billion in assets under management, according to RWA.xyz data.
The growing adoption of tokenized U.S. Treasuries allows institutional investors and DeFi protocols to “park” their idle cash directly on the blockchain, earning a secure yield derived from the underlying assets—something traditional stablecoins do not offer natively.
Expansion to the BNB Chain and the Future of RWA
BUIDL’s multifaceted expansion will be on the market’s radar in the coming weeks. Parallel to the agreement with Binance, Securitize announced that the tokenized fund will also expand to the BNB Chain (BNB).
This move is crucial, as it takes BUIDL out of its original ecosystem (primarily Ethereum) and dramatically increases its interoperability.
By being available on the BNB Chain, investors will be able to use the yield-generating asset within that network’s vast ecosystem of decentralized finance (DeFi) applications, using it for lending, yield farming, or as collateral in native protocols.
The dual strategy of being accepted as top-tier institutional collateral on the largest centralized platform (Binance) while simultaneously integrating into one of the most active DeFi chains (BNB) positions BlackRock’s tokenized fund BUIDL not only as a store of value, but as a fundamental pillar in the convergence of TradFi and DeFi.
