The world’s largest tokenized Treasury fund is expanding its reach. BlackRock’s USD Institutional Digital Liquidity Fund - better known as BUIDL - is now live on BNB Chain, deepening the partnership between the world’s biggest asset manager and the world’s largest crypto exchange.
With more than $2.5 billion invested, BUIDL’s expansion means the fund can now be used as off-exchange collateral for trading on Binance. Both companies said the integration strengthens BUIDL’s position as a “core component of onchain finance,” allowing professional traders to deploy capital more efficiently while maintaining exposure to tokenized Treasuries.
A New Collateral Option for Active Traders
Binance’s Head of VIP & Institutional, Catherine Chen, said the fund is being connected to the exchange’s triparty banking agents – a key part of traditional short-term secured funding markets – along with its crypto-native custody provider, Ceffu.
Chen noted that institutions have been looking for yield-bearing, dollar-pegged assets they can use as collateral instead of holding idle stablecoins. BUIDL, which is designed to track the U.S. dollar, fills that role.
Expanding Beyond Ethereum
Issued by Securitize, BUIDL is already one of the most widely deployed real-world asset products onchain. Before adding BNB Chain, it was available on:
- Ethereum
- Avalanche
- Aptos
- Solana
- Arbitrum
- Polygon
- Optimism
BNB Chain becomes the latest network to support the fund – and comes at a time when the chain has enjoyed heavy momentum thanks to rising usage in derivatives platforms like Aster and integrations with Binance Alpha, Binance Wallet, and real-world asset protocols such as Ondo Finance.
