BlackRock Expands BUIDL Program to Aptos, Arbitrum, and Optimism

  • BlackRock has announced that its tokenized US Treasury fund is now available on additional networks.
  • The firm has expanded beyond Ethereum, with the BlackRock USD Institutional Digital Liquidity Fund (BUIDL) now accessible on Aptos, Avalanche, Arbitrum, Polygon, and Optimism.

BlackRock has broadened the reach of its tokenized US Treasury fund by adding support for several other blockchain networks beyond Ethereum.

In an announcement on November 13, the asset manager said the BlackRock USD Institutional Digital Liquidity Fund (BUIDL) is now accessible on Aptos (APT), Avalanche (AVAX), Arbitrum (ARB), Polygon (POL), and Optimism (OP).

This expansion means investors can access BUIDL—the tokenized fund launched in March 2024 and issued by real-world asset tokenization provider Securitize—on chains other than Ethereum.

BlackRock will launch new BUIDL share classes on the five networks, offering native interactions and near real-time access year-round.

Beneficiaries include traditional investors, decentralized autonomous organizations, and other crypto-native firms. Carlos Domingo, CEO and co-founder of Securitize, commented:

“Real-world asset tokenization is evolving, and we’re excited to see these blockchains added to enhance the BUIDL ecosystem’s potential. With these new chains, we expect more investors to leverage the underlying technology to improve efficiencies in areas that have been difficult to address.”

The BlackRock BUIDL fund has become the largest tokenized fund in the world by assets under management. According to data from RWA.xyz, the global on-chain real-world assets market exceeds $13 billion.

Market data show roughly $2.3 billion is held in tokenized treasuries, a segment dominated by BlackRock. BUIDL currently accounts for $521 million of that market, ahead of Ondo US Dollar Yield, which reports $451 million in AUM.
