BlackRock has broadened the reach of its $2.5 billion tokenized money market fund, BUIDL, with two major developments that deepen its integration across the crypto ecosystem. The fund, which is tokenized by Securitize and backed by short-term U.S. Treasury bills, has now been approved as institutional collateral on Binance and has expanded to the BNB Chain.
BUIDL Now Accepted as Institutional Collateral on Binance
The most notable update is Binance’s decision to accept BUIDL as off-exchange collateral for its VIP and institutional traders. Clients can hold their BUIDL tokens with qualified custodians or banking partners rather than on the exchange itself, reducing counterparty risk while still accessing Binance’s liquidity and trading services.
This model mirrors the industry shift toward off-exchange settlement, a structure favored by major institutions seeking to limit exposure while maintaining active trading strategies. By supporting BUIDL, Binance adds a yield-generating collateral option backed by traditional financial assets.
BUIDL Expands to BNB Chain
BlackRock has also introduced a new class of BUIDL shares on the BNB Chain, bringing the tokenized fund to one of the largest blockchain ecosystems. Previously available only on Ethereum, BUIDL’s multichain expansion increases its utility across decentralized finance (DeFi), institutional rails, and RWA-focused applications.
The BNB Chain integration enables faster and cheaper transactions while allowing developers and institutions to incorporate BUIDL into on-chain strategies ranging from collateralized lending to liquidity management.
Bridging Traditional Finance and Crypto
This dual expansion underscores the accelerating convergence of traditional finance (TradFi) and blockchain infrastructure. With large institutions demanding more transparent, programmable, and efficient financial products, tokenized funds like BUIDL are becoming a cornerstone of the emerging tokenized asset economy.
By expanding to new blockchains and partnering with major exchanges, BlackRock is positioning BUIDL as a backbone asset for on-chain capital markets, providing interest-bearing, highly liquid, and fully regulated exposure to U.S. Treasury bills.
Growing On-Chain Utility
Since its launch, BUIDL has steadily broadened its footprint and is now available across multiple networks and institutional platforms. Its latest integrations with Binance and the BNB Chain further enhance its practical use cases, making it easier for institutional clients to incorporate tokenized real-world assets into trading, custody, and DeFi strategies.
