Did Binance Recently Checkmate Institutional Investment? BUIDL Crypto Launches with Binance as Collateral
BlackRock’s $2.5Bn tokenized Treasury fund has integrated into Binance’s collateral framework, bringing a Wall Street-caliber asset directly into the realm of cryptocurrency trading.
On November 15, BlackRock, Securitize, and Binance announced that the BlackRock USD Institutional Digital Liquidity Fund (BUIDL) has been authorized as off-exchange collateral for institutional clients.
Additionally, a new share class for the fund launched on BNB Chain on Friday. This announcement provides larger traders the opportunity to access yield-bearing US Treasury exposure while trading on Binance, utilizing the same asset within one of the busiest Decentralized finance platforms available.

Why Is Binance Incorporating BlackRock’s BUIDL into Its Off-Exchange Collateral Framework?
Binance has implemented BUIDL into its off-exchange collateral system, which operates via banking triparty agreements and its custodian partner, Ceffu.
The platform indicates that there has been increasing buyer interest over recent months. “Our institutional clients have requested more interest-generating stable assets to hold as collateral while they trade actively on our network,” stated Catherine Chen, who oversees the VIP and Institutional sector at Binance.
Binance previously permitted other tokenized yield assets, like USYC and cUSDO, in this arrangement. Now, BUIDL stands as the inaugural BlackRock asset included in that collateral category.
BUIDL represents BlackRock’s on-chain institutional market fluidity fund. It was introduced in March 2024 as the company’s first tokenized offering on a public distributed database and is issued through Securitize.
This development allows VIP and institutional clients to store their BUIDL tokens with a regulated financial institution or with Ceffu, while still earning trading credit on Binance.
Clients are no longer required to maintain those assets on the trading network.
BUIDL is recognized as BlackRock’s on-chain institutional liquidity fund, launched in March 2024 as the firm’s initial tokenized offering on a public blockchain via Securitize.

What Makes BUIDL the Largest Tokenized US Treasury Fund on Public Blockchains?
The fund allocates assets toward US cash, short-term Treasuries, and repurchase agreements. It aims to maintain a consistent $1 value while providing daily dividends to eligible investors.
Since launch, the fund has grown to become the largest tokenized US Treasury product operating on public blockchains, boasting over $2.5Bn in assets as of mid-November 2025.
Earlier this year, the fund surpassed competitors like Hashnote’s USYC and Franklin Templeton’s BENJI. Its expansion also contributed to enhancing the overall tokenized Treasuries trading market to an estimated $8.6–$8.7Bn, according to recent RWA analytics.BUIDL is already functioning across multiple blockchains, including Ethereum, Arbitrum, Polygon, Optimism, Avalanche, Solana, and Aptos.
The introduction of a BNB Chain share class increases that total to nine networks, highlighting the clarity of the multi-chain strategy. According to Securitize, approximately two-thirds of BUIDL’s assets are now located beyond ETH.
On Friday, BNB was trading at about $920, slightly elevated on the day following a week characterized by significant fluctuations among major cryptocurrencies.
Carlos Domingo, co-founder and CEO of Securitize, remarked that BUIDL’s expanded footprint and its new function as collateral “significantly broadens its reach and applicability” and illustrates how regulated real-world assets can effectively integrate into daily trading activities.
Nevertheless, this growth has refocused some attention on BNB and the broader BNB Chain ecosystem during a period characterized by market market fluctuation.
