Stable Sea, WisdomTree embed tokenized Treasuries for SMBs

Stable Sea has integrated WisdomTree’s tokenized government money market fund WTGXX into its payments and treasury management platform, allowing small and medium-sized business customers to move stablecoin balances onchain into the fund and back into stablecoins for payouts. The companies announced the tie-up on Wednesday.

WTGXX invests primarily in U.S. government bonds and targets a stable $1 net asset value per share. The fund uses continuous dividend accrual and a 24-hour income smoothing method. It manages roughly $857 million in assets and publishes a yield above many traditional business savings accounts.

Under the integration, Stable Sea customers can sweep idle stablecoin cash into WTGXX to earn yield and redeem holdings into the stablecoin of their choice when they need liquidity for payments. The firms spent about a year building the redemption flow that converts fund holdings back into stablecoins for global payouts.

Will Peck, head of digital assets at WisdomTree, described the goal as ‘We want to be the default for “money at rest” within the onchain space.' He also highlighted an estimated $5 trillion sitting in business bank accounts that yield under 2% APY and said moving some of that volume onchain could simplify routing cash into and out of money market funds for payments and treasury use.

Stable Sea primarily serves non-crypto-native clients. About 90% of its customer base are small and medium enterprises that do not operate mainly in crypto, including service and manufacturing firms. The company also offers over-the-counter trading and the ability for corporate clients to buy bitcoin. Stable Sea was founded by former employees of a major payments company.

Tokenized Treasury products have expanded rapidly. Onchain tokenized Treasuries total roughly $15.07 billion across dozens of assets, and several tokenized funds now manage assets in the billions. Market participants say demand for onchain government money market products accelerated after the passage of the GENIUS Act last year.

WisdomTree is a limited partner in a venture fund that holds a stake in Stable Sea. The two firms said the initial rollout will start small and may broaden over time. They presented the offering as a way for businesses to earn yields that exceed typical bank savings rates while keeping the ability to convert holdings back to stablecoins for immediate operational use.
