On November 14, BNB Chain shared an official announcement, in which it announced that BlackRock’s USD Institutional Digital Liquidity Fund (BUIDL) has joined the network, which will be powered by Securitize and Wormhole.
“This moment connects traditional finance and blockchain in a way that feels inevitable. It’s the trust and scale of the world’s biggest asset manager meeting the speed, efficiency, and accessibility of onchain systems, and it’s all happening on BNB Chain,” stated in a press release.
Binance to Accept BlackRock’s BUIDL as Collateral
The main highlight of this development is that Binance has also announced that it will now accept BlackRock’s tokenized treasury fund, BUIDL, as collateral for institutional trading. This integration will allow major financial institutions to capitalize on investment in regulated instruments that earn yields while being used to secure trades on one of the biggest cryptocurrency exchanges.
This decision to integrate BUIDL addresses a major demand from Binance’s institutional client base for more efficient capital management. By allowing BUIDL to be used as off-exchange collateral, institutions no longer have to choose between earning yield on safe assets and having immediate access to trading capital.
Sarah Song, Head of Business Development at BNB Chain, shared his view on this development, saying, “BNB Chain is designed for scalable, low-cost, and secure financial applications, and we’re excited to welcome BUIDL to our ecosystem. BUIDL is turning real-world assets into programmable financial instruments, enabling entirely new types of investment strategies onchain.”
Carlos Domingo, Co-founder and CEO of Securitize, stated in the official announcement, “Expanding BUIDL to the BNB Chain and making it available as collateral on the Binance exchange further extends its accessibility and reinforces our mission to bring regulated real-world assets onchain while unlocking new forms of utility that were previously out of reach.”
The process will work through Binance’s Banking Triparty solution, which is designed to protect investment. An institution can hold assets, including now BUIDL tokens, in secure third-party custody with a regulated bank.
The inclusion of BUIDL comes after it was launched by the asset management company BlackRock in March 2024. BUIDL was the firm’s first tokenized fund on a public blockchain. It offers qualified investors exposure to the U.S. Treasury yields with the added benefits of blockchain technology. Since its inception, this tokenized fund has attracted $2.5 billion in market capitalization.
BUIDL’s Expansion of Its Ecosystem on Aptos and Avalanche
The asset management company is executing a major expansion beyond its original home on the Ethereum blockchain. As the world’s largest tokenized treasury fund, BUIDL provides investors with a stable, dollar-pegged token that generates yield from the U.S. Treasury bills.
In October 2025, BlackRock committed a landmark $500 million allocation of BUIDL to the Aptos blockchain. This massive infusion instantly propelled the total value of tokenized real-world assets on Aptos to over $1.2 billion.
By spreading its assets across Aptos, Avalanche, and other chains like Polygon, BlackRock is not just hedging its bets but actively responding to investor demand for more efficient and cost-effective platforms.
The impact of this development is a major acceleration in the adoption of tokenized real-world assets (RWAs). By making its fund accessible on multiple blockchains through custodians like BNY Mellon, the asset management company is providing a foundational building block for the next generation of on-chain finance.
