Key Points
- BlackRock’s BUIDL tokenized money market fund crossed $1.7 billion AUM as it expanded to Solana, the seventh blockchain to support the fund.
- BUIDL holds 34% market share of tokenized US Treasuries, up 240% from $500 million in July 2024, per RWA.xyz.
- DeFi wallets on Solana, Ethereum, Aptos, Arbitrum, Avalanche, Optimism, and Polygon can now hold BUIDL exposure with daily-accrued Treasury yield.
BlackRock’s BUIDL tokenized money market fund crossed $1.7 billion in assets under management as it expanded to Solana on March 25, 2026, the seventh blockchain to support the fund. Securitize CEO Carlos Domingo announced the Solana expansion as a “natural next step” as demand for tokenized real-world assets continues to rise. For DeFi users on Solana with stablecoins in a wallet, the practical change is that BUIDL exposure is now reachable on the chain they already use, with daily Treasury yield accruing and dividends paid monthly through Securitize.
BUIDL Joins Solana As BlackRock’s 7th Tokenized Treasury Rail
Securitize CEO Carlos Domingo called the Solana expansion a “natural next step” as demand for tokenized real-world assets continues to rise.
BUIDL launched in March 2024 in partnership with Securitize and was initially Ethereum-only.
It has since expanded to Aptos, Arbitrum, Avalanche, Optimism, and Polygon, with Solana now the seventh chain.
Solana Foundation President Lily Liu said the network’s “speed, low costs, and developer activity” make it well-suited for tokenized assets.
BUIDL is pegged to the US dollar and pays daily accrued dividends monthly through Securitize, with $7 million in dividends distributed as of August 2024.
The $1.7 billion milestone makes BUIDL the largest tokenized money market fund by AUM, with all other tokenized Treasury products combined trailing the BlackRock-backed product.
How $1.7B AUM And 34% Share Stack Against Hashnote, Franklin, Ondo
BUIDL leads the tokenized US Treasury sector with $1.7 billion market capitalization and 34% market share, per RWA.xyz.
It is followed by Hashnote, Franklin Templeton’s FOBXX, and Ondo Finance’s USDY in the tokenized Treasury league table.
BUIDL’s growth has been steep. In July 2024 the fund held $500 million; by March 2026 it crossed $1 billion, and by May 2026 it surpassed $1.7 billion, representing a 240% gain in roughly seven months from the mid-2024 baseline.
Strip away the BlackRock branding and the practical question is whether a Solana wallet can now hold the same Treasury yield exposure as an Ethereum wallet, and the answer is yes, through the same Securitize-managed wrapper.
Readers can compare tokenized Treasury yields across issuers as competition intensifies across chains.
Ethereum-based treasuries still dominate the sector with $3.6 billion total market cap, representing 72% of the entire tokenized Treasury market. The Solana expansion is BUIDL’s bet on diversification beyond Ethereum’s incumbent advantage.
DeFiLlama data shows BUIDL gained $700 million in new investments over 11 days, pushing AUM past $1.7 billion. The fund first crossed $1 billion on March 13.
What Lily Liu And Carlos Domingo Signal About The Tokenized Yield Race
The Solana expansion is BUIDL’s second multi-chain move after a November 2025 launch on Aptos, Arbitrum, Avalanche, Optimism, and Polygon.
That timeline shows acceleration. From single-chain Ethereum in March 2024 to seven chains by May 2026 is unusually fast institutional expansion.
Carlos Domingo’s “natural next step” framing puts BUIDL squarely in the multi-chain tokenized Treasury race, where Franklin Templeton’s FOBXX is also available on eight blockchain platforms including Stellar, Polygon, and Avalanche.
Lily Liu’s quoted emphasis on Solana’s “speed, low costs, and developer activity” reflects the same speed-versus-liquidity bet covered in our earlier read on Solana’s $2.8B RWA milestone. BUIDL on Solana is the first major institutional anchor that validates that bet.
For DeFi users, the practical move is direct: BUIDL exposure now reachable from any institutional wallet on the seven supported chains, with Treasury yield accruing daily and distributions paid monthly through Securitize.
The forward read is whether the next chain BUIDL targets is XRP Ledger, Canton Network, or stays within the existing multi-chain footprint after this round of expansion completes and the AUM consolidates.
Whether BUIDL holds 34% market share as Hashnote and Franklin Templeton expand multi-chain depends on which chains attract the most onchain Treasury inflows in the coming quarters. The next milestone reveal will tell.

Frequently Asked Questions
What is BUIDL and where can I hold it now?
BUIDL is BlackRock’s USD Institutional Digital Liquidity Fund, a tokenized money market fund holding short-term US Treasury instruments. As of May 2026, it is available on Ethereum, Solana, Aptos, Arbitrum, Avalanche, Optimism, and Polygon, with $1.7 billion in assets under management.
How does BUIDL’s yield work?
BUIDL pays daily accrued dividends, distributed monthly through Securitize. The yield tracks short-term US Treasury rates because the fund holds Treasury instruments. As of August 2024, the fund had distributed $7 million in dividends to investors.
Can a retail DeFi user actually buy BUIDL on Solana?
BUIDL is a tokenized money market fund with KYC requirements for direct purchase, structured through Securitize. Retail DeFi users typically cannot buy BUIDL directly without institutional onboarding, though some DeFi protocols may eventually offer wrapped exposure. The Solana expansion makes the underlying token transferable on a low-fee chain, which matters for institutional buyers rebalancing positions.
How does BUIDL compare to Franklin Templeton’s FOBXX and Ondo USDY?
BUIDL holds 34% market share of tokenized US Treasuries, ahead of Hashnote, Franklin Templeton’s FOBXX, and Ondo Finance’s USDY. FOBXX is available on eight blockchain platforms with $671 million AUM. USDY targets a similar DeFi-accessible tokenized Treasury product.
