Summary
State Street Corporation and Galaxy Digital have announced the launch of SWEEP, a tokenized private liquidity fund designed to modernize institutional cash management by moving it onchain. The fund enables stablecoin holders to access yield-bearing assets with 24/7 liquidity and programmatic trading capabilities—a structural advantage over traditional cash management solutions constrained by market hours and settlement cycles.
SWEEP is constructed to allow institutional investors to deposit stablecoins and receive exposure to short-term U.S. Treasury yields onchain. The fund architecture leverages multiple specialized service providers: Galaxy Digital provides the core tokenization technology and digital infrastructure; Anchorage Digital serves as the digital custodian for stablecoin holdings; NAV Consulting operates as transfer agent; and State Street Bank and Trust Company maintains custody of securities. This multi-vendor approach reflects the hybrid infrastructure required for institutional-grade onchain asset management.
The fund's technology stack demonstrates State Street's commitment to blockchain interoperability and institutional-grade standards. SWEEP launches on Solana blockchain with planned integration to Stellar and Ethereum. The fund utilizes Chainlink NAVLink for daily net asset value (NAV) publication onchain and Chainlink CCIP for secure cross-chain data transfer. This infrastructure selection underscores institutional requirements for transparent, auditable pricing and seamless asset movement across blockchain networks.
The partnership represents an expansion of State Street's existing relationship with Galaxy, which began in September 2024. According to State Street Investment Management, SWEEP positions the firm to serve two distinct client bases simultaneously: DeFi-native participants seeking institutional-grade yield products and traditional institutional investors exploring onchain infrastructure. State Street's positioning as a "bridge" between these markets reflects the ongoing convergence of digital asset markets with traditional finance.
The launch aligns with State Street's broader digital asset strategy, emphasizing foundational capabilities in custody, settlement, and investment management onchain. By enabling 24/7 cash management and programmatic liquidity, SWEEP addresses a structural gap in institutional treasury operations and reinforces State Street's evolution from a traditional custodian into a multi-chain infrastructure provider serving the emerging onchain institutional market.
