On November 14, 2025, a significant step was taken in merging traditional finance with the crypto world, as BlackRock’s $2.5 billion tokenized fund, BUIDL, was integrated into the Binance ecosystem and expanded to BNB Chain. This move provides institutional traders with new tools for capital efficiency and broadens the utility of tokenized real-world assets (RWAs).
BUIDL’s Strategic Expansion
BlackRock’s USD Institutional Digital Liquidity Fund (BUIDL) announced a dual-pronged integration, significantly enhancing its accessibility and utility for a crypto-native audience.
Firstly, Binance will now accept BUIDL as off-exchange collateral for its institutional and advanced traders. This means qualified clients can pledge their BUIDL tokens, held securely in custody with partners like Ceffu and triparty banking agents, as collateral to secure trades on the exchange without having to sell their assets. This setup meets a direct request from institutional clients for more interest-bearing stable assets to use while trading actively.
Concurrently, a new share class of BUIDL is being launched on BNB Chain. This expansion onto a high-performance, low-cost blockchain network increases the fund’s interoperability, allowing it to be used within the vibrant ecosystem of decentralized applications (DApps) and DeFi protocols built on BNB Chain.
Why This Integration Matters
This development is more than a technical listing; it represents a growing convergence between traditional and on-chain finance.
For institutional traders, BUIDL offers a unique combination of stability and yield. It is tokenized by Securitize and functions similarly to a stablecoin, pegged 1:1 to the U.S. dollar and backed by U.S. Treasury bills and repurchase agreements. However, unlike most stablecoins, BUIDL pays out a yield to its holders from its underlying assets, with recent rates around 3.7% to 4% annually. This allows traders to potentially earn a return on their collateral while it’s being used to support their trading activities.
Robbie Mitchnick, BlackRock’s Global Head of Digital Assets, stated that enabling BUIDL as collateral across leading digital market infrastructures helps “bring foundational elements of traditional finance into the onchain finance arena. Carlos Domingo, CEO of Securitize, views this as unlocking “new forms of utility that were previously out of reach” for regulated real-world assets.
The arrival of a heavyweight tokenized asset like BUIDL on BNB Chain signals that real-world assets are becoming a foundational layer for the Web3 economy, turning traditional financial instruments into programmable building blocks for a new generation of on-chain investment strategies.
