Stable Sea Adds WisdomTree Tokenized Treasury Fund for Corporate Cash

Treasury management startup Stable Sea has integrated WisdomTree’s tokenized US Treasury money market fund into its platform, in a move aimed at helping businesses generate yield on idle cash.

On Wednesday, Stable Sea said the WisdomTree Government Money Market Digital Fund (WTGXX) is now available on its platform, allowing corporate clients to allocate excess cash to a government-backed fund rather than leaving it in low-yield bank accounts.

Stable Sea provides software that automatically reallocates — or “sweeps” — corporate cash balances into yield-bearing instruments. By integrating WTGXX, the company is extending that functionality to a tokenized fund that settles on blockchain infrastructure.

The product is aimed at businesses and corporate treasury teams seeking more efficient ways to manage liquidity and earn returns on cash reserves.

Companies access the fund through Stable Sea’s platform, which connects to existing financial systems. Clients are still required to complete onboarding and standard compliance checks, reflecting the regulated nature of the underlying fund.

WTGXX invests primarily in short-term US government securities, such as Treasury bills, and is structured as a money market fund. Its “tokenized” format means ownership shares are recorded onchain, which can enable faster settlement and more automated transactions compared to traditional fund infrastructure.

The fund had total assets of $857.64 million, as of April 28, and offered a daily yield of 3.43%, according to WisdomTree.

Tokenized money market funds gain traction among institutions

Tokenized money market funds are seeing increased adoption as investors and institutions look for low-risk yield with greater operational flexibility. One of the key selling points is liquidity. 

WisdomTree recently enabled 24/7 trading for its WTGXX fund after receiving approval from the US Securities and Exchange Commission, allowing investors to access and move funds outside traditional market hours.

The use case is also expanding beyond cash management. Franklin Templeton and Binance have partnered to allow tokenized money market funds to be used as off-exchange collateral. Eligible institutions can pledge tokenized fund shares issued via Franklin Templeton’s Benji platform to support trading activity on Binance.

Standard Chartered this week launched a new framework that enables its institutional clients to use BlackRock’s tokenized short-term Treasurys fund as collateral for trading on crypto exchange OKX.

In an email to Cointelegraph following the launch, Richard Baker, CEO and founder of Tokenovate, said StanChart’s move “signals another instance of tokenization’s transition into the heart of core market infrastructure, elevating it from innovation to something structurally transformative.”

Other traditional finance players are entering the market as well. Northern Trust Asset Management recently launched a tokenized share class of its Treasury Instruments Portfolio, marking its entry into blockchain-based fund infrastructure.
