Stable Sea on Wednesday announced a strategic partnership with WisdomTree to embed access to the asset manager’s tokenized funds inside its business treasury platform, opening a new distribution channel for onchain dollar yield beyond crypto-native users.
The integration begins with the WisdomTree Treasury Money Market Digital Fund (WTGXX), which currently holds about $855 million in tokenized U.S. Treasuries and ranks as the sixth-largest tokenized money market fund tracked by RWAxyz. Eligible Stable Sea Terminal users can establish a limited-scope broker-dealer relationship with WisdomTree Securities to route orders into select WisdomTree tokenized funds directly from the Stable Sea interface.
For users, that means daily dividend accrual, continuous yield allocation based on intra-day holdings, and daily liquidity through WTGXX, plus the option to set rules that automatically sweep idle balances into the fund and unwind back to stablecoins when liquidity is needed.
“US businesses collectively hold more than $5 trillion in cash and cash equivalent accounts that earn minimal to no interest,” said Tanner Taddeo, CEO and co-founder of Stable Sea. “This collaboration with WisdomTree brings institutional-grade cash management and 24/7/365 yield exposure into a technology product built for modern operators.”
From Stablecoin Off-Ramps to Treasury Stack
Founded in 2024, San Francisco-based Stable Sea originally pitched itself as a fix for the “final mile” of stablecoin utility, building enterprise-grade off-ramps that let fintechs, payment service providers, and global businesses convert stablecoins into local fiat in single trades of up to $50 million, replacing the patchwork of OTC desks and Telegram-based dealer relationships that businesses had been stitching together.
Stable Sea Terminal launched in May 2025 as the productized version of that workflow, combining stablecoin purchasing, conversion, and global payouts in a single API and dashboard. The WisdomTree deal extends the platform further, layering tokenized money market exposure on top of payments and custody.
Tokenized MMFs Push Beyond DeFi
The deal also extends WisdomTree’s recent run of WTGXX integrations into a different distribution lane: business treasury workflows rather than DeFi protocols.
Last week, pre-launch lender Lotus tapped WTGXX for its LotusUSD vault reserves, and in March, Plume launched a payroll pilot routing employee salaries into the fund. Last November, Plume also integrated WisdomTree tokenized funds via OpenTrade into its Nest staking vaults.
“Treasury management use cases have been a leading driver of the adoption we have seen of our tokenized money market fund WTGXX in the past year,” said Will Peck, Head of Digital Assets at WisdomTree.
Tokenized U.S. Treasury and money market funds have grown from under $1 billion in early 2024 to roughly $15 billion across 76 assets today, per RWAxyz, led by Circle’s USYC, BlackRock’s BUIDL, and Ondo’s U.S. Dollar Yield funds. WTGXX itself surged more than 700% between May and August last year. WisdomTree manages approximately $160 billion across its businesses.
