WisdomTree and MoonPay announced on September 17 a strategic collaboration to make the WisdomTree Treasury Money Market Digital Fund (WTGXX) more accessible to U.S. investors and integrate it into MoonPay's stablecoin reserve management.
Under the agreement, WisdomTree will use MoonPay's blockchain technology to build a new access point for WTGXX, extending distribution beyond WisdomTree Securities, its FINRA-member broker-dealer. MoonPay's network includes more than 35 million accounts and over 1,700 partners. MoonPay plans to hold WTGXX as part of its stablecoin reserves, linking a regulated tokenized money market fund to dollar-denominated digital asset infrastructure.
Key facts: WTGXX seeks to preserve a $1.00 per share value and invests in short-term U.S. government securities and eligible money market instruments. It is not a bank account and is not FDIC-insured. WisdomTree reported roughly $176.7 billion in global assets under management. The tokenized U.S. Treasury market stood at about $15.4 billion, with WTGXX accounting for roughly $1.23 billion. WTGXX recorded about $466 million in net flows over the past 30 days, while the Ondo U.S. Dollar Yield fund posted about $66 million in positive net flows over the same period.
MoonPay launched its enterprise stablecoin business in November 2025 and holds a Dutch electronic money institution license for stablecoin issuance. The companies said MoonPay is not acting as a broker-dealer or investment adviser with respect to WTGXX.
WisdomTree CEO Jonathan Steinberg said: “Money moves differently today, and investing needs to keep pace. Working with MoonPay as an access point can give eligible U.S. investors another path to deploy their assets into WTGXX.” Caroline D. Pham, CEO of MoonPay Institutional, added: “Our working relationship with WisdomTree demonstrates how financial innovation can enable better experiences for investors in U.S. regulated markets and products.”
The partnership could expand beyond the U.S. and include additional tokenized funds, positioning tokenized Treasury products as financial infrastructure for stablecoin reserve management rather than standalone investments.
