Securitize announced that the BlackRock USD Institutional Digital Liquidity Fund (BUIDL) has surpassed $1 billion in assets under management (AUM), marking a key milestone in the development of tokenized finance.
BUIDL, BlackRock’s first tokenized fund on a public blockchain, launched in March 2024 and provides qualified investors access to U.S. dollar yields with flexible custody, daily dividend payouts, and near-instant peer-to-peer transfers.
The fund’s features have enabled institutional use cases in treasury management, stablecoin reserves, decentralized finance (DeFi), and trading collateral, demonstrating the growing demand for tokenized assets.
Initially deployed on Ethereum, BUIDL has expanded across multiple blockchain networks, including Aptos, Arbitrum, Avalanche, Optimism, and Polygon.
Cross-chain interoperability is facilitated by Wormhole, allowing secure and efficient transfers of tokenized assets. Custodians supporting BUIDL investors include Anchorage Digital, BitGo, Copper, and Fireblocks, with Bank of New York Mellon serving as the fund’s cash and securities custodian.
“BlackRock’s BUIDL surpassing $1 billion in AUM represents a significant moment for on-chain finance,” said Securitize Co-founder and CEO Carlos Domingo. “We are proud of our pioneering work in making this product a reality, demonstrating that tokenized securities are no longer a concept but a tangible investment vehicle.”
Joseph Chalom, BlackRock’s Head of Strategic Ecosystem Partnerships, emphasized the fund’s role in institutional finance.
“BUIDL showcases the viability of real-world assets on-chain, offering investors enhanced liquidity, flexibility, and yield opportunities. We are excited to see its continued growth,” he said.
The expansion of BUIDL highlights the broader momentum in real-world asset (RWA) tokenization, a market gaining increasing traction among institutional investors.
Securitize, which provides tokenization services in partnership with firms such as Apollo, Hamilton Lane, and KKR, continues to push the boundaries of on-chain finance.
Securitize operates as a broker-dealer and alternative trading system (ATS) regulated by the U.S. Securities and Exchange Commission (SEC) and has been recognized as a 2025 Forbes Top 50 Fintech company.
