Stablecoin management firm Stable Sea has announced a partnership with WisdomTree to provide corporate clients access to tokenized money market funds, allowing businesses to earn yield on idle stablecoin balances. The integration, disclosed on Wednesday, enables clients to deploy operating cash into WisdomTree's Government Money Market Digital Fund (WTGXX), a tokenized fund primarily invested in U.S. government bonds.
According to Will Peck, head of digital assets at WisdomTree, this collaboration is a first-of-its-kind, integrating a tokenized fund directly into a third-party payments and treasury management platform. "We want to be the default for 'money at rest' within the onchain space," Peck told The Block. The fund maintains a stable $1 net asset value and offers a 3.5% seven-day APY, above the sector average of 3.05%.
Stable Sea co-founder and CEO Tanner Taddeo noted that 90% of the firm's clients are not crypto-native, including a painting company and a U.S.-based manufacturer. The partnership aims to move some of the estimated $5 trillion in idle business cash sitting in low-yield accounts into productive onchain assets. The tokenized Treasury sector has grown rapidly, with over $15 billion in onchain value across 76 assets, driven partly by regulatory clarity from the GENIUS Act.
The integration provides seamless conversion between stablecoins and yield-bearing positions, supporting both 'money at rest' and 'money in motion' for global payments. WisdomTree is also a limited partner in a venture fund that has invested in Stable Sea, which was founded by former Block employees.
