Stable Sea Adds WisdomTree Tokenized Treasury Fund

Stable Sea on Wednesday added WisdomTree’s Government Money Market Digital Fund (WTGXX) to its treasury management platform, enabling corporate clients to automatically sweep idle cash into a tokenized U.S. Treasury money market fund.

Stable Sea’s software reallocates corporate cash balances into yield-bearing instruments. With the integration, WTGXX is now an available destination for automatic sweeps. Firms access the fund through Stable Sea’s platform, which links to existing banking and accounting systems. Companies must complete onboarding and standard compliance checks before investing.

WTGXX is structured as a money market fund that holds short-term U.S. government securities such as Treasury bills. The fund’s tokenized share class records ownership onchain, which can enable faster settlement and more automated transactions compared with traditional fund structures. WisdomTree reported WTGXX had $857.64 million in assets as of April 28 and a daily yield of 3.43%.

The Securities and Exchange Commission granted WisdomTree approval to allow round-the-clock trading of WTGXX, permitting investors to trade and move shares outside regular market hours.

Institutional use of tokenized money market funds is expanding. Franklin Templeton has a partnership with Binance to allow tokenized fund shares to serve as off-exchange collateral. Standard Chartered set up a framework for clients to use BlackRock’s tokenized short-term Treasurys fund as collateral for trading on OKX. Northern Trust Asset Management launched a tokenized share class of its Treasury Instruments Portfolio.

Richard Baker, CEO and founder of Tokenovate, wrote that tokenization is shifting from an innovation into a structural part of market infrastructure.

Stable Sea said the integration gives corporate treasury teams a way to move cash into a government-backed, yield-bearing product while maintaining regulatory controls and connections to existing systems. The tokenized format supports automated liquidity management workflows and blockchain settlement.
