WisdomTree and MoonPay expand US access to tokenized money market fund

WisdomTree and MoonPay have partnered to expand US investor access to a tokenized Treasury money market fund. MoonPay will also use the fund, WisdomTree Treasury Money Market Digital Fund (WTGXX), as part of its stablecoin reserve strategy.

Tokenized fund access built on MoonPay technology

In a Thursday announcement, the companies said the fund issuer will use MoonPay’s technology to create an access point for WTGXX. The tokenized money market mutual fund targets a $1 share price.

WisdomTree will use MoonPay’s network of more than 35 million accounts as part of the arrangement.

MoonPay to place WTGXX in stablecoin reserves

MoonPay, which provides infrastructure for moving between fiat and digital assets, plans to use WTGXX as part of its stablecoin reserve management stack.

MoonPay launched its enterprise stablecoin business in November 2025. It issues dollar-denominated stablecoins across several blockchains, backed by US dollars and other high-quality liquid assets held in segregated accounts.

Potential expansion to other tokenized funds

WisdomTree said the collaboration could extend to additional tokenized funds, including in markets outside the United States. WisdomTree manages about $176.7 billion in assets.

Fund size and recent flow data

As of Thursday, the tokenized US Treasury market stood at about $15.4 billion. WTGXX accounted for about $1.23 billion, according to RWA.xyz data.

WTGXX logged net flows of $466 million in the past 30 days, calculated as tokens minted minus tokens burned. Ondo U.S. Dollar Yield fund (USDY) was the only other tokenized Treasurys fund with positive net flows of $66 million in the same period.

Why it matters

The deal ties a tokenized money market product and its $1 share-price target to MoonPay’s distribution and stablecoin reserve framework, potentially widening the routes through which US investors can access tokenized Treasury exposure.
