BlackRock today announced the launch of its USD Institutional Digital Liquidity Fund (BUIDL) on the BNB Chain, creating a $2.5 billion tokenized real‑world asset vehicle that is the largest of its kind to date.
The fund’s rapid growth is evident: AUM climbed from roughly $400 million in February 2025 to almost $2.9 billion by October 2025, a 600 % increase that underscores strong demand for regulated, yield‑bearing digital assets.
BlackRock chose BNB Chain for its low‑cost, high‑throughput architecture and its close partnership with Binance, the world’s largest cryptocurrency exchange. Wormhole’s cross‑chain bridge and Securitize’s tokenization platform enable the BUIDL token to be used as collateral on Binance, giving institutional investors a new, compliant way to leverage treasury‑backed assets in DeFi trading.
Securitize’s CEO Carlos Domingo said the expansion “extends BUIDL’s reach and utility, unlocking new forms of on‑chain collateral that were previously unavailable.” BlackRock’s Global Head of Digital Assets, Robbie Mitchnick, added that the move “brings foundational elements of traditional finance into on‑chain finance,” while BNB Chain’s Head of Business Development, Sarah Song, highlighted the ecosystem’s scalability and security as key enablers.
The launch positions BlackRock as a leader in the tokenized real‑world asset market, where RWAs have surpassed $36 billion in total value. By offering a yield‑bearing token that can compete with stablecoins for collateral, BlackRock taps into institutional demand for compliant, interest‑bearing digital assets and strengthens its multi‑chain strategy that began with an Ethereum launch in March 2024.
The integration also signals broader industry momentum: Binance’s institutional clients now have access to a regulated, interest‑earning asset that can be used to back trades, potentially reshaping collateral practices in the crypto market.
In sum, BlackRock’s BUIDL launch on BNB Chain demonstrates a strategic commitment to tokenization, expands institutional access to yield‑bearing digital assets, and may accelerate the adoption of regulated RWAs across the broader financial ecosystem.
