BlackRock's tokenized money-market fund, BUIDL, has crossed $900 million on Avalanche and roughly doubled its size on the chain within a week, according to RWA.xyz data cited by WuBlockchain on July 12, 2026. The number refers to BUIDL's Avalanche allocation specifically, not the fund's full multi-chain supply.
BUIDL, formally the BlackRock USD Institutional Digital Liquidity Fund, holds cash, US Treasury bills, and repurchase agreements, and issues a token that stays pegged to $1 while paying yield to holders. It launched in March 2024 with Securitize as the tokenization and transfer agent, and has since expanded from Ethereum onto several other chains. A jump from roughly $450 million to $900 million on Avalanche in seven days is a large move for a product whose growth usually comes in institutional-sized but infrequent subscriptions.
The mechanics behind a one-week jump
Money-market fund tokens do not double through retail inflows. They move when a small number of large allocators mint new shares. A doubling on Avalanche most likely reflects one or a few sizable subscriptions, plus possible bridging of existing BUIDL supply from another chain into Avalanche's version through Securitize's infrastructure. Without an issuer statement breaking down new mint versus cross-chain transfer, the split between fresh capital and migrated capital is unclear, and the single RWA.xyz snapshot is the basis for the figure.
The choice of Avalanche matters here. The chain has been positioning its subnet architecture for institutional and tokenized-asset use, and BUIDL sitting near $900 million there gives Avalanche one of the larger single tokenized-fund balances outside Ethereum. It also lands the same week that BlackRock's broader tokenized footprint on Avalanche drew attention, with commentary pointing to Avalanche gaining traction on real-world assets.
Tokenized cash as plumbing, not a product
The reason a treasury fund token keeps showing up in crypto headlines is that it has quietly become infrastructure. BUIDL and its competitors are used as yield-bearing collateral: firms park idle balances in tokenized T-bills instead of a non-yielding stablecoin, then borrow against or redeem those tokens when they need dollars. Ondo, Circle, and several derivatives venues have wired tokenized money funds into their reserve and margin systems over the past year.
That places BUIDL close to the stablecoin rails that increasingly settle on-chain payments. A tokenized fund that pays around the T-bill rate is a more capital-efficient reserve asset than a zero-yield token, which is why issuers keep integrating them. The same logic sits behind the wave of stablecoin yield products aimed at fintechs, where the pitch is putting reserves to work rather than leaving them idle.
Reading the number carefully
A doubling looks dramatic, and the direction is real, but the framing deserves discipline. $900 million on Avalanche is a chain-level figure, not BUIDL's total, and a single week of growth driven by a handful of allocators can partly reverse if one of them redeems. Tokenized money-market funds are concentrated instruments: the same feature that lets them grow fast also lets them shrink fast when a large holder exits.
The tokenization trend around it is not thin, though. Tokenized equities set records in June, and on-chain real-world-asset volumes have been climbing across the board, so BUIDL's Avalanche jump fits a broader pattern rather than standing alone. For crypto users, the practical takeaway is narrow but concrete: the dollars backing more of the stablecoins and settlement layers you touch are increasingly held as tokenized Treasuries earning yield for their issuers, and BlackRock now runs one of the largest such pools on a second major chain.
For everyday spending, none of this changes what a card does at the point of sale today. It does shape the reserve economics behind the tokens that fund those cards, which is where the next round of yield-sharing and fee competition is likely to play out.
Overview
BlackRock's BUIDL fund topped $900 million on Avalanche and roughly doubled there within a week, per RWA.xyz data cited on July 12, 2026. The figure is Avalanche-specific and most likely reflects a few large subscriptions or cross-chain transfers rather than broad inflows. The bigger signal is that tokenized Treasury funds are becoming the collateral layer under stablecoins and on-chain settlement, giving Avalanche one of the larger tokenized-fund balances outside Ethereum.
