WisdomTree and MoonPay Partner to Expand US Access to Tokenized MMFs

WisdomTree and MoonPay have announced a partnership aimed at widening U.S. investor access to a tokenized money market mutual fund tied to U.S. Treasuries. The companies say MoonPay will provide technology that helps power a distribution and access layer for WisdomTree’s tokenized product, the WisdomTree Treasury Money Market Digital Fund (WTGXX).

According to the Thursday announcement, the tokenized fund is designed to maintain a $1 share price, and the issuer will use MoonPay’s infrastructure to connect to a broader user base. The firms also disclosed that MoonPay plans to incorporate WTGXX into its stablecoin reserve management workflow.

Key takeaways

• WisdomTree says MoonPay will supply technology that forms an access point for WTGXX, a tokenized U.S. Treasury money market fund.
• The fund targets a $1 per-share price; the issuer plans to leverage MoonPay’s network of more than 35 million accounts.
• MoonPay intends to use WTGXX as part of its stablecoin reserve management stack.
• RWA.xyz data cited by the companies places tokenized U.S. Treasury market value at about $15.4 billion, with WTGXX representing about $1.23 billion.
• WTGXX saw net token flows of $466 million over the past 30 days, based on the difference between tokens minted and burned.

How MoonPay’s infrastructure plugs into WTGXX

The partnership centers on distribution infrastructure rather than on changing the fund’s core strategy. WisdomTree’s WTGXX is a tokenized money market mutual fund that aims to keep its value stable at $1 per share. Under the deal, the issuer plans to use MoonPay’s technology to build an access point that can route eligible participants into the tokenized fund.

The companies say this access layer is expected to give WisdomTree reach into MoonPay’s broader network, described as spanning more than 35 million accounts. For investors, that matters less for the “tokenization” branding and more for the practical question of whether they can actually reach and transact in these products efficiently. Expanding access points has often been a gating factor for real-world assets (RWAs), where compliance and onboarding complexity can slow distribution.

WTGXX as a stablecoin reserve tool

MoonPay’s involvement is not limited to retail-style access. The company also said it plans to use WTGXX as part of its stablecoin reserve management stack. MoonPay is a financial technology firm that provides infrastructure for moving between fiat and digital assets, and it issues dollar-denominated stablecoins backed by U.S. dollars and other high-quality liquid assets held in segregated accounts.

In the announcement, MoonPay pointed to its earlier buildout of an enterprise stablecoin business, which it says it launched in November 2025. The stated reserve architecture—assets held in segregated accounts—highlights one of the recurring themes in stablecoin infrastructure: reserve management needs can be as operational and regulatory-heavy as they are technical. Using a tokenized Treasury-linked money market product could, in theory, align reserve workflows with on-chain settlement and compliance-friendly custody structures, though the announcement does not detail the mechanics beyond saying WTGXX will be part of MoonPay’s stack.

For market participants, the implication is that tokenized Treasuries are increasingly being treated not only as standalone investment vehicles, but also as building blocks inside broader digital-asset financial plumbing.

Market footprint and recent momentum in tokenized Treasuries

The announcement situates the partnership within the growth of tokenized U.S. Treasury markets. On Thursday, the tokenized U.S. Treasury market was cited at about $15.4 billion, with WTGXX accounting for roughly $1.23 billion, according to RWA.xyz data.

Momentum metrics were also provided. WisdomTree and MoonPay said WTGXX logged net flows of $466 million over the past 30 days. The companies define net flows as the difference between tokens minted and tokens burned. By that measure, WTGXX was not alone in positive movement, but it stood out among tokenized Treasury offerings: Ondo’s U.S. Dollar Yield fund (USDY) was described as the only other tokenized Treasuries fund to show positive net flows in the same period, totaling $66 million.

Those figures matter because they frame the partnership as a bet on demand and distribution at a time when tokenized Treasury funds are competing for inflows. If the tokenization ecosystem’s growth is still concentrated in a small set of products, expanding access via established on-ramps could further skew which funds attract additional capital.

What could follow: more tokenized funds and broader geography

Beyond WTGXX, the partners suggested the collaboration could extend to other tokenized funds. WisdomTree said the arrangement may expand, including into markets outside the United States, though it did not specify which products or regions would come next.

For investors and builders, that “optionality” is a meaningful signal. Tokenized money market funds and Treasury-linked instruments rely on a combination of legal structure, investor onboarding, custody and settlement design, and ongoing operations. If a tech-enabled access point proves effective for one fund—particularly one that aims for a stable share price—it may become a reusable distribution model for additional offerings.

However, readers should also note what is not spelled out in the announcement: the companies did not provide details on timeline, target jurisdictions for expansion, onboarding prerequisites, or how MoonPay’s role changes once investors move from access into ongoing investment/redemption flows. Those are key operational variables that typically determine whether demand converts into sustained AUM growth.

With WTGXX already showing significant net flows over the past month and a substantial share of the tokenized Treasury market by the companies’ cited RWA.xyz data, the partnership’s next test will be execution: whether MoonPay’s expanded access layer translates into continued inflows and whether MoonPay’s stablecoin reserve use case scales smoothly as the stablecoin business grows. Investors watching RWAs and stablecoin infrastructure should look for updates on adoption, jurisdictional rollout, and any additional funds that may be brought into the same access framework.
