Summary
State Street Investment Management and Galaxy Asset Management have launched the State Street Galaxy Onchain Liquidity Sweep Fund (SWEEP), a tokenized private liquidity fund designed to bring institutional cash management on-chain with round-the-clock access and yield-bearing stablecoin holdings. The fund enables subscribers to convert stablecoins into a yield-generating asset while maintaining liquidity through 24/7 on-chain redemptions, subject to portfolio stablecoin availability.
The SWEEP fund initially deploys on the Solana blockchain with planned integrations on Stellar and Ethereum, supporting a multi-chain infrastructure strategy. Investors can subscribe and redeem using PayPal USD (PYUSD) stablecoins, though access is restricted to Qualified Purchasers meeting specified eligibility criteria and minimum investment amounts. According to State Street officials, SWEEP is designed specifically to enable stablecoin holders to sweep their holdings into yield-bearing assets while maintaining programmatic access for liquidity management.
The fund's technical infrastructure reflects a specialized custody and operational model. Anchorage serves as the digital custodian for stablecoin investments, while NAV Consulting functions as transfer agent. Galaxy leverages Chainlink NAVLink to publish the fund's daily net asset value on-chain and Chainlink Cross-Chain Interoperability Protocol (CCIP) for secure cross-chain operations. State Street Bank and Trust Company retains custody responsibilities for securities holdings, establishing a hybrid on-chain/traditional custody framework.
The launch deepens State Street Investment Management's existing relationship with Galaxy and signals the institution's commitment to digital asset infrastructure for institutional clients. By combining short-duration U.S. Treasury exposure with on-chain stablecoin liquidity, SWEEP positions itself as a bridge between traditional fixed-income cash management and emerging tokenized finance infrastructure. The fund's architecture—supported by legal counsel from Jones Day—demonstrates institutional-grade operational standards for tokenized private liquidity vehicles.
