BlackRock is expanding its money market fund to the Solana network, bringing its accessibility to seven blockchain networks.

Securitize, a real-world asset tokenization platform that has partnered with BlackRock, Apollo, and Hamilton Lane to bring tokenized assets on-chain,, announced the expansion to Solana (SOL) on Tuesday, March 25, 2025.

This means the BlackRock USD Institutional Digital Liquidity Fund, known as BUIDL, is now available on Ethereum, Aptos, Arbitrum, Optimism, Avalanche, Polygon, and Solana. The company is expanding its tokenized treasury fund’s shares to Solana amid growing interest in the broader tokenized assets market.

BUIDL, launched in March 2024, has surpassed $1 billion in assets under management, and offers U.S. dollar yield to qualified investors.

The on-chain product benefits from flexible custody, with current providers including Copper, Anchorage Digital, and Fireblocks. Notably, BUIDL offers daily dividend payouts.

Prioritizing speed and cost

Solana’s speed and cost-effectiveness are key features that investors using BlackRock’s money market fund will likely find attractive.

“As the market for RWAs and tokenized treasuries gains momentum, expanding BUIDL to Solana—a blockchain known for its speed, scalability, and cost efficiency—is a natural next step,” said Carlos Domingo, co-founder and chief executive officer of Securitize. 

BUIDL currently holds $1.7 billion in market cap, outpacing the Hashnote Short Duration Yield Coin at $764 million and Franklin Templeton’s On-Chain U.S. Government Money Fund at $792 million. According to RWA.xyz, BlackRock’s tokenized fund has recorded a notable $235 million in the last 30 days.

BlackRock’s expansion of BUIDL to Solana comes as the asset manager also takes its spot Bitcoin exchange-traded fund to Europe. The fund, launched in January 2024, is the world’s largest by net assets at over $50 billion, with net inflows of nearly $40 billion.
