WisdomTree and MoonPay Collaborate to Broaden US Tokenized MMF Access

WisdomTree and MoonPay have announced a partnership designed to make a tokenized U.S. Treasury money market fund easier for U.S. investors to access. The companies say MoonPay will supply technology that serves as a distribution access point for WisdomTree’s WisdomTree Treasury Money Market Digital Fund (WTGXX), which aims to maintain a $1 share price.

MoonPay also plans to use WTGXX within its stablecoin reserve management stack. The move highlights how regulated cash-like products are increasingly being structured to plug directly into stablecoin operations, rather than remaining siloed as standalone tokenized funds.

Key takeaways

• MoonPay will be used as an access point for WisdomTree’s tokenized Treasury money market fund, WTGXX.
• WisdomTree says the integration is meant to leverage MoonPay’s network of more than 35 million accounts.
• MoonPay intends to include WTGXX as part of its stablecoin reserve management approach.
• RWA.xyz data shows tokenized U.S. Treasury markets at about $15.4 billion, with WTGXX around $1.23 billion.
• WTGXX reportedly recorded $466 million in net flows over the prior 30 days, calculated from token minting and burning.

A tokenized money market fund built around $1 stability

The partnership centers on WTGXX, WisdomTree’s tokenized money market mutual fund. According to the companies’ announcement, the fund is structured to target a stable $1 share price—an important design choice for investors seeking lower-volatility exposure compared with traditional crypto assets.

In this setup, MoonPay’s technology is expected to create the practical on-ramp for investors who want exposure to the tokenized fund. The firms framed the distribution benefit around scale: WisdomTree said the arrangement would give it access to MoonPay’s network of more than 35 million accounts.

For market participants, this matters because the usability gap has often been the limiting factor for tokenized funds. Tokenization alone doesn’t guarantee demand; access, custody workflows, and investor onboarding typically determine whether a product actually attracts capital.

Why MoonPay wants WTGXX in its reserves

MoonPay, which provides infrastructure for moving between fiat and digital assets, plans to use WTGXX as part of its stablecoin reserve management. In the announcement, the companies positioned the fund as a fit for the kinds of high-quality, liquid assets that stablecoin issuers and treasury operators typically seek.

MoonPay said it launched its enterprise stablecoin business in November 2025. The company issues dollar-denominated stablecoins across several blockchains, backed by U.S. dollars and other high-quality liquid assets held in segregated accounts.

This is the first-time, at least in the way described publicly here, that a specific tokenized Treasury money market fund has been tied directly to MoonPay’s reserve stack. If the integration works smoothly, it could help normalize a broader “tokenized cash management” model—where Treasury-like products become operational inputs to stablecoin liquidity and redemption capacity.

How big is WTGXX in the tokenized Treasury market?

RWA.xyz data cited in the announcement suggests the tokenized U.S. Treasury market is roughly $15.4 billion in size. Within that category, WTGXX accounts for about $1.23 billion.

While WTGXX is not the largest tokenized Treasury product on the list by the numbers provided, it is significant enough to matter to both sides of the ecosystem—investors allocating to tokenized money market instruments and operators building stablecoin reserve workflows.

Volume and momentum are also part of the story. The companies said WTGXX recorded net flows of $466 million in the past 30 days. Net flows were calculated as the difference between tokens minted and tokens burned. In the same timeframe, the Ondo U.S. Dollar Yield fund (USDY) was the only other tokenized Treasurys fund mentioned as having positive net flows, at $66 million.

This relative outperformance matters because flows often function as a proxy for perceived usability and demand. If WTGXX continues to attract inflows after the distribution changes, it could strengthen its role as a reserve asset candidate across the stablecoin infrastructure stack.

Potential expansion beyond the first integration

WisdomTree said the collaboration could extend to additional tokenized funds, including in markets outside the United States. The firm also reported that it manages about $176.7 billion in assets, underscoring that it is approaching tokenized Treasurys and cash-like instruments as part of a broader product strategy rather than a one-off experiment.

For investors, the watch item is whether expanded distribution and stablecoin reserve adoption increase real-world liquidity and reduce friction across onboarding and transfers. For builders, the broader implication is that stablecoin reserves may increasingly rely on tokenized, share-priced cash instruments—creating demand for issuance rails and distribution access points similar to the one MoonPay is providing here.

Still, several practical questions remain open. The announcement focuses on the technology and the intended uses, but readers should watch for details on how investors experience the onboarding process, what custody and settlement mechanics are involved for U.S. participants, and whether MoonPay’s reserve integration affects WTGXX’s day-to-day token mint-and-burn dynamics.

Going forward, the clearest signals to track are whether tokenized Treasury market share shifts toward WTGXX after this access partnership, and whether MoonPay’s reserve allocation approach expands to other tokenized cash products as additional markets and funds are considered.
