BlackRock’s BUIDL joins Aptos, Arbitrum, Avalanche, Optimism and Polygon

BlackRock is expanding its tokenized fund — BUIDL — to multiple blockchains.

BlackRock has announced the expansion of its BlackRock USD Institutional Digital Liquidity Fund — BUIDL — which is tokenized by Securitize, to five additional blockchains: Aptos (APT), Arbitrum (ARB), Avalanche (AVAX), Optimism (OP), and Polygon (MATIC).

Initially launched on Ethereum (ETH) in March 2024, BUIDL quickly became the world’s largest tokenized fund by assets under management, reaching this milestone in under 40 days.

BUIDL’s broader ecosystem 

By introducing new share classes on these blockchains, BlackRock seeks to enhance access to BUIDL’s ecosystem, benefiting investors, decentralized autonomous organizations, and firms focused on digital assets.

Adding these blockchains enables BUIDL investors to benefit from on-chain yield, peer-to-peer transfers, and on-chain dividend accrual and distribution. Each blockchain provides unique features, from Arbitrum’s low fees and rapid transactions to Avalanche’s scalability and Aptos’s advanced security.

BlackRock’s fund administrator, BNY Mellon, has supported this integration, ensuring continuity for investors across digital and traditional financial systems.

This move underscores BlackRock’s commitment to digital finance innovation, giving developers and users in diverse ecosystems greater flexibility to build and interact with tokenized financial products on their preferred platforms.
