Summary
State Street Investment Management and Galaxy Asset Management announced the launch of SWEEP (State Street Galaxy Onchain Liquidity Sweep Fund) on May 5, 2026, marking a significant institutional entry into tokenized cash management. SWEEP is structured as a private liquidity fund designed to operate continuously on blockchain infrastructure, enabling qualified purchasers to deposit stablecoins and access yield-generating assets with 24/7 redemption capabilities—a material departure from traditional money market fund mechanics tied to market hours and settlement delays.
The fund's architecture combines short-duration U.S. Treasury exposure with blockchain-based infrastructure, allowing stablecoin holders to "sweep" their holdings into a yield-bearing asset. Subscription and redemption occur via PayPal USD (PYUSD) stablecoins, supporting real-time cash management operations. SWEEP initially launches on the Solana blockchain, with planned expansion to Stellar and Ethereum, positioning it as a multi-chain institutional solution from inception.
The operational backbone reflects institutional-grade infrastructure standards. Galaxy Digital's Digital Infrastructure provides tokenization and management technology for SWEEP tokens. Anchorage serves as the fund's digital custodian for stablecoin investments, while State Street Bank and Trust Company maintains custody of securities holdings. NAV Consulting manages transfer agent functions. Critically, the fund leverages Chainlink NAVLink to publish its daily Net Asset Value onchain and Chainlink CCIP for secure cross-chain interoperability—elements essential for institutional confidence and regulatory transparency.
State Street characterizes SWEEP as central to its broader digital strategy: bridging traditional institutional asset management with onchain investment solutions while serving DeFi-native clients. The launch underscores institutional appetite for continuous liquidity access and the technical maturation of blockchain infrastructure supporting regulated fund operations. This product directly addresses inefficiencies in conventional cash management—settlement delays, reduced weekend and after-hours liquidity, and limited yield on stablecoin holdings—positioning tokenized sweep funds as a potential structural alternative to traditional money market vehicles for institutions with significant stablecoin positions.
