Summary
State Street Investment Management, Galaxy Digital, and Ondo Finance announced on December 10, 2025, plans to launch SWEEP—the State Street Galaxy Onchain Liquidity Sweep Fund—a tokenized private liquidity fund engineered to deliver institutional-grade cash management directly onchain. The product targets deployment on Solana in early 2026 and represents a strategic convergence between traditional custodial banking infrastructure, digital asset management, and decentralized finance innovation.
Ondo Finance's OUSG fund will anchor the offering with a planned $200 million investment, serving as the lead institutional investor. This allocation directly supports OUSG's dual mandate: diversifying reserve composition while deepening 24/7 liquidity access across tokenized instruments. OUSG, introduced in 2023, pioneered seamless onchain exposure to U.S. Treasuries with rapid stablecoin convertibility. The platform has since evolved to offer instant daily subscriptions and redemptions, expanded multi-chain deployment, and reserve diversification into institutional-grade products including BlackRock's BUIDL and Fidelity's FDIT, positioning it as a cornerstone of onchain cash management infrastructure.
SWEEP addresses a critical institutional need: native cash management for digital asset markets. The fund permits subscriptions and redemptions using PayPal USD (PYUSD) stablecoins, creating operational efficiency for investors managing positions across traditional and decentralized protocols. By integrating with established stablecoin rails, SWEEP eliminates friction in the cash-to-crypto transaction pipeline while maintaining institutional governance standards.
The partnership underscores accelerating institutional appetite for tokenized liquidity products. State Street's participation validates the market opportunity for onchain cash equivalents at scale, while Galaxy Digital's involvement strengthens the digital asset infrastructure layer. Ondo's anchor position reflects confidence in SWEEP's ability to meet institutional liquidity requirements while serving as a strategic reserve diversification vehicle for OUSG, reinforcing the broader ecosystem of tokenized real-world assets.
