Stable Sea announced a strategic relationship with WisdomTree to bring tokenized treasury access to businesses by embedding access to WisdomTree’s tokenized funds inside Stable Sea’s business treasury platform.

The integration begins with the WisdomTree Treasury Money Market Digital Fund (WTGXX), which The Defiant says “currently holds about $855 million in tokenized U.S. Treasuries,” while Cointelegraph and The Block both cite WTGXX’s scale as “$857 million in total assets” and “about $857 million in managed assets,” respectively.

PR Newswire frames the collaboration as enabling Stable Sea users to earn yield by investing operating cash in WisdomTree’s tokenized money market fund through an embedded workflow, and it specifies that eligible users may establish a limited scope broker-dealer relationship with WisdomTree Securities, Inc. for transactions in shares of select WisdomTree tokenized funds “beginning with” WTGXX.

The Defiant describes what that means for users: “daily dividend accrual,” “continuous yield allocation based on intra-day holdings,” and “daily liquidity through WTGXX,” plus rules that automatically sweep idle balances and unwind back to stablecoins when liquidity is needed.

Cointelegraph adds that WisdomTree 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 Block similarly emphasizes that Stable Sea users will be able to sweep idle stablecoin balances into yield-bearing tokenized funds and swap back as liquidity is needed, positioning the integration as a distribution channel beyond crypto-native users.

Stable Sea’s CEO and co-founder Tanner Taddeo framed the partnership as a way to put idle business cash to work, arguing that “US businesses collectively hold more than $5 trillion in cash and cash equivalent accounts that earn minimal to no interest.”

In PR Newswire’s account, Taddeo said the collaboration “brings institutional-grade cash management and 24/7/365 yield exposure into a technology product built for modern operators,” and it ties that promise to features including “daily dividend accrual” and “continuous 24/7/365 yield allocation based on intra-day holdings.”

The Defiant adds that the platform’s integration is designed for “business operating cash,” offering “daily liquidity through WTGXX” and the ability to “set rules that automatically sweep idle balances into the fund and unwind back to stablecoins when liquidity is needed.”

The Block describes Stable Sea as having started out helping businesses “onramp into crypto, move stablecoins around the world, and cash out into dozens of local currencies,” and it says the WisdomTree tie-up adds “corporate access to yield-bearing capital markets products.”

Cointelegraph and PR Newswire both connect the value proposition to operational convenience, with Cointelegraph emphasizing that investors can “access and move funds outside traditional market hours” and PR Newswire describing “daily liquidity availability via WTGXX.”

The Defiant also situates the deal as an expansion beyond crypto-native users, saying it “opens a new distribution channel for onchain dollar yield beyond crypto-native users.”

The partnership coverage repeatedly ties the integration to specific mechanics for trading, yield accrual, and liquidity, with multiple outlets describing how WTGXX’s tokenized structure is meant to behave inside business workflows.

PR Newswire says the platform delivers “daily dividend accrual” and “continuous 24/7/365 yield allocation based on intra-day holdings,” while also stating “daily liquidity availability via WTGXX.”

It further describes “24/7 trading with instant settlement,” and it explicitly contrasts this with “T+1 delays of traditional markets.”

The Defiant similarly describes “daily dividend accrual” and “continuous yield allocation based on intra-day holdings,” and it adds that users can “unwind back to stablecoins when liquidity is needed.”

Cointelegraph provides the regulatory and operational hook for that 24/7 access, stating that WisdomTree enabled “24/7 trading for its WTGXX fund after receiving approval from the US Securities and Exchange Commission.”

The Block adds a fund-level detail, saying WTGXX is “a tokenized fund that invests primarily in U.S. government bonds to provide holders access to yield while maintaining a stable $1 net asset value per share.”

Several outlets place the Stable Sea–WisdomTree integration inside a broader expansion narrative for tokenized money market funds and tokenized Treasuries, using specific market-size figures and fund rankings.

PR Newswire says “Assets in tokenized U.S. Treasury and money market funds have grown from under $1 billion in early 2024 to more than $10 billion by early 2026,” and it attributes the growth to offerings from major asset managers like WisdomTree.

PR Newswire

The Defiant similarly reports that tokenized money market exposure is part of a “fast-growing segment,” and it states that WTGXX “ranks as the sixth-largest tokenized money market fund tracked by RWAxyz.”

Cointelegraph adds a separate scale figure for WTGXX’s assets—“$857 million in total assets”—and it says tokenized money market funds are seeing “increased adoption” as investors and institutions look for “low-risk yield with greater operational flexibility.”

The Defiant also provides a performance datapoint, saying “WTGXX itself surged more than 700% between May and August last year.”

The Block includes a sector-wide yield figure, saying “Tokenized Treasury funds are currently averaging around a 3.05% seven-day APY across the sector,” and it reports WTGXX’s offering as “3.5%,” while also noting that RWA.xyz tracks it.

The integration is also described as part of a wider ecosystem of tokenized-cash infrastructure, with multiple outlets naming other firms, platforms, and regulatory touchpoints.

Cointelegraph says tokenized money market funds are being used as off-exchange collateral through a partnership between Franklin Templeton and Binance, and it states that “Eligible institutions can pledge tokenized fund shares issued via Franklin Templeton’s Benji platform to support trading activity on Binance.”

It also says Standard Chartered launched a framework enabling its institutional clients to use BlackRock's tokenized short-term Treasurys fund as collateral for trading on crypto exchange OKX, and it quotes Tokenovate CEO and founder Richard Baker saying 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.”

PR Newswire anchors the Stable Sea access model in a regulated broker-dealer relationship, stating that eligible Stable Sea users may establish a “limited scope broker-dealer relationship with WisdomTree Securities, Inc., an SEC registered broker-dealer,” to facilitate transactions in select tokenized funds.

The Defiant adds that eligible Stable Sea Terminal users can establish a “limited-scope broker-dealer relationship with WisdomTree Securities” to route orders “directly from the Stable Sea interface.”

Looking ahead, PR Newswire says the collaboration expands Stable Sea Terminal into “onchain treasury management,” and it describes the platform as built to move, manage and grow treasury capital using “stablecoin and digital asset infrastructure,” with WTGXX as the starting point for tokenized treasury access.
