Partnership Mechanics
MoonPay is a financial technology company that provides infrastructure for moving between fiat and digital assets. The company launched its enterprise stablecoin business in November 2025, issuing dollar-denominated stablecoins across several blockchains backed by US dollars and other high-quality liquid assets held in segregated accounts.
WTGXX is a tokenized money market mutual fund that seeks to maintain a $1 share price. By incorporating the fund into its stablecoin reserve stack, MoonPay gains exposure to Treasury-backed yield while offering investors a regulated, liquid alternative. The arrangement gives WisdomTree access to MoonPay's network of more than 35 million accounts, significantly broadening the fund's addressable market.
Market Context
WisdomTree manages about $176.7 billion in assets. WTGXX has emerged as a dominant player in the tokenized Treasury space. On Thursday, the tokenized US Treasury market stood at about $15.4 billion, with WTGXX accounting for about $1.23 billion. The fund's momentum is evident: it has logged net flows of $466 million in the past 30 days.
Ondo U.S. Dollar Yield fund (USDY) was the only other tokenized Treasurys fund that saw positive net flows of $66 million in the period, underscoring WTGXX's dominance.
Expansion Path
The collaboration could expand to additional tokenized funds, including in markets outside the United States. This signals WisdomTree's intent to deepen its presence in on-chain finance while MoonPay strengthens its stablecoin infrastructure with regulated, yield-bearing assets.
