Stable Sea adds 2 WisdomTree funds for corporate cash

Stable Sea has added two WisdomTree digital funds to its treasury platform, giving eligible businesses access to three SEC-registered products with minimum investments starting at $1.

Stable Sea adds two WisdomTree funds

Stable Sea said the WisdomTree Short-Duration Income Digital Fund and WisdomTree Floating Rate Treasury Digital Fund are now available through Stable Sea Terminal, its cash-management platform for finance teams.

The additions expand a relationship that began in April, when the platform started offering the WisdomTree Treasury Money Market Digital Fund. In April, crypto.news reported the first integration, which allowed corporate clients to place idle cash in a tokenized fund holding short-term U.S. government securities.

Eligible Stable Sea users now have three funds with different investment objectives, costs, yields, and minimums. Finance teams can place buy and sell orders from the same dashboard they use to oversee company cash, according to the firms.

Access is provided through WisdomTree Securities Inc., an SEC-registered broker-dealer and member of the Financial Industry Regulatory Authority. Before placing an order, each eligible Stable Sea Terminal user must establish a relationship with WisdomTree Securities and complete the required account-opening process.

Stable Sea CEO and co-founder Tanner Taddeo told crypto.news that the expanded selection lets a business match its cash holdings with the time at which it expects to need the money.

“By expanding our partnership with WisdomTree, we now offer three distinct funds that cover different business needs: a straight money market option, a floating-rate option, and an actively managed income option, so a business can match its cash to how soon it actually needs it,” Taddeo said.

According to Taddeo, such choices have long been available to large corporate treasury departments but have remained difficult for many smaller companies to obtain.

Three tokenized funds serve different cash needs

At the lowest entry point, the WisdomTree Treasury Money Market Digital Fund, or WTGXX, requires a minimum investment of $1. The SEC-registered money market fund invests in short-term U.S. Treasury securities and accrues dividends daily.

WTGXX carries an expense ratio of 0.25% and had a seven-day SEC yield of 3.46% based on the figures provided with the announcement. Its investment objective combines current income with capital preservation, liquidity and maintenance of a stable net asset value of $1 per share.

A second choice, FLTTX, seeks to track an index of floating-rate U.S. Treasury obligations before fees and expenses. Unlike conventional fixed-rate Treasury securities, the interest rates on the fund’s underlying obligations adjust using scheduled Treasury auctions.

FLTTX has a $25 minimum investment and a 0.05% expense ratio. The fund’s 30-day SEC yield was listed at 3.81% in the information supplied for the expansion.

WTSIX also requires at least $25, although its strategy differs from that of the two Treasury-focused products. WisdomTree actively manages the fund to seek income while maintaining an objective of preserving capital.

The short-duration income fund charges an expense ratio of 0.40% and had a reported 30-day SEC yield of 4.42%. Its holdings may expose investors to credit, interest-rate, and income risks that differ from those attached to a money market fund or a portfolio limited to floating-rate Treasury obligations.

SEC yields provide standardized measures based on a fund’s recent income, but they change with market conditions and do not guarantee future returns. The products are investments rather than bank deposits, meaning they are not insured by the Federal Deposit Insurance Corporation and can lose value.

WisdomTree targets barriers facing finance teams

WisdomTree Head of Digital Assets Will Peck told crypto.news that the response to the original single-fund arrangement showed demand from businesses seeking access to regulated cash-management products.

“Different businesses have a variety of liquidity and cash-management needs, while high minimums and manual account processes have historically created barriers to accessing institutional-grade cash-management products.”

Adding the funds gives eligible finance departments more choices without requiring them to leave Stable Sea’s existing interface, according to Peck. The arrangement does not make the funds available to every company automatically, since eligibility checks and the WisdomTree Securities account process still apply.

Stable Sea said U.S. businesses collectively hold more than $5 trillion in cash and cash-equivalent accounts that earn little or no interest. The company presented the three-fund selection as a way for qualifying finance teams to divide operating cash according to expected liquidity needs instead of applying one product to every balance.

The low minimums contrast with some investment products designed for large issuers or institutional clients. An April report on Morgan Stanley described a stablecoin reserve portfolio carrying a $10 million minimum investment and a 0.15% management fee.

Morgan Stanley’s product invests in cash, U.S. Treasury securities with maturities of 93 days or less, and overnight repurchase agreements backed by Treasuries. Although the portfolio was designed for stablecoin issuers, the bank said other investors could also participate.

Tokenized funds remain regulated securities

Placing fund ownership records on a blockchain does not remove the securities rules, identity checks, or transfer controls attached to the underlying investment. A July tokenized fund explainer noted that access to many such products remains permissioned, with investors required to complete identity checks and use approved wallets.

Stable Sea and WisdomTree’s arrangement follows the same regulated model. Each of the three products is registered with the SEC, while transactions are handled through WisdomTree Securities rather than through an open, permissionless crypto market.

SEC registration also does not amount to a government guarantee or approval of an investment’s returns. Fund buyers remain exposed to the terms, fees and risks listed in each product’s prospectus, including possible loss of principal.

Industry tracker RWA.xyz put the value of tokenized real-world assets in the United States above $31 billion by mid-2026, compared with roughly $6 billion at the start of 2025. Tokenized Treasury and money market products accounted for more than $15 billion of the total, according to figures cited by Stable Sea.

Growth in the segment has brought asset managers and payment networks into products tied to government debt. In February 2025, Mastercard added Ondo Finance to its Multi-Token Network, allowing participating businesses to access tokenized Treasuries while using traditional banking infrastructure for settlement.

WisdomTree managed more than $150 billion in assets when Stable Sea announced the expanded relationship. WTGXX, FLTTX, and WTSIX remain subject to their respective prospectuses, eligibility requirements, expense ratios, and changing SEC yields.
