Summary
State Street Investment Management and Galaxy Asset Management announced on May 5, 2026, the launch of the State Street Galaxy Onchain Liquidity Sweep Fund (SWEEP), representing a significant institutional adoption milestone in tokenized cash management. The fund is structured as a tokenized private liquidity vehicle designed to enable qualified institutional investors to generate yield on stablecoin holdings while maintaining 24/7 onchain liquidity and programmatic trading capabilities, subject to stablecoin availability within the fund's portfolio.
SWEEP launched on the Solana blockchain, a selection driven by Solana's high transaction throughput and minimal transaction costs—critical operational parameters for continuous institutional cash management. The fund roadmap includes expansion to Ethereum and Stellar, establishing multi-chain accessibility that accommodates institutional investors with diverse blockchain infrastructure preferences and operational requirements. This phased deployment strategy balances launch velocity with the technical and regulatory complexity of supporting multiple blockchain networks simultaneously.
The infrastructure arrangement reflects a specialized division of responsibilities across institutional-grade service providers. Galaxy Digital, through its Galaxy Asset Management affiliate, supplies the core tokenization technology and digital infrastructure enabling SWEEP's issuance and management. Anchorage Digital operates as the fund's digital custodian specifically for stablecoin investments, while State Street Bank and Trust Company maintains traditional custody over securities holdings. NAV Consulting serves as transfer agent. To ensure transparent, real-time net asset value publication onchain and secure cross-chain data transmission, Galaxy leverages Chainlink's NAVLink for daily NAV updates and Chainlink CCIP for cross-chain interoperability protocols.
The product launch reflects State Street's stated digital strategy to offer investment solutions directly onchain and support continuous, algorithm-enabled trading for institutional cash management. State Street positions SWEEP as a bridge infrastructure serving two distinct client constituencies: DeFi-native institutions requiring native blockchain settlement, and traditional institutional asset managers seeking entry into tokenized markets. Jones Day provided legal advisory services to Galaxy on the transaction structure and fund documentation.
