Summary
The fund's core functionality allows stablecoin holders to sweep capital into a yield-bearing tokenized asset, providing continuous access to liquidity outside conventional market windows. This structure is purpose-built for institutions operating natively in digital asset markets and for traditional institutional clients seeking to migrate treasury and cash management operations onchain. The product combines State Street's institutional-grade cash and liquidity management capabilities with Galaxy's digital infrastructure expertise.
Architecturally, SWEEP launches on the Solana blockchain with expansion planned for Stellar and Ethereum, reflecting multi-chain settlement strategy for institutional adoption. Galaxy's Digital Infrastructure provides tokenization technology and platform management. The fund relies on Chainlink's NAVLink protocol to publish daily net asset value onchain and Chainlink CCIP for secure cross-chain interoperability, ensuring transparent, real-time fund valuation and seamless capital movement across blockchains.
The custody and operational structure layers traditional institutional safeguards onto digital infrastructure. Anchorage Digital serves as digital custodian for stablecoin positions, NAV Consulting provides transfer agent services, and State Street Bank and Trust Company acts as custodian for securities holdings. This tri-layer custody model addresses regulatory and operational requirements for institutional investors while maintaining 24/7 settlement capabilities native to blockchain networks.
The launch signals State Street's strategic positioning as both a digital-first platform for crypto-native institutions and a bridge enabling traditional institutional capital to access onchain cash management infrastructure. The initiative reflects institutional demand for continuous liquidity management in tokenized markets and validates the institutional blockchain custody and settlement ecosystem's maturation.
