The launch represents a milestone in State Street's digital strategy to offer investment solutions onchain and support 24/7 programmatic trading and liquidity for cash management. Building on its legacy as an innovator, State Street continues to invest in foundational digital asset capabilities across investment management and custody, offering cutting-edge, onchain investment solutions to DeFi-native clients, as well as acting as the bridge to traditional institutional clients looking to move onchain.

SWEEP is powered by Galaxy's Digital Infrastructure, which provides the tokenization technology and digital infrastructure supporting the issuance and management of SWEEP tokens. The fund is built to allow stablecoin holders to sweep their stablecoin into a yield bearing asset. SWEEP launches on the Solana blockchain, with additional blockchain integrations planned, including Stellar and Ethereum. Anchorage serves as the fund's digital custodian for stablecoin investments, NAV Consulting serves as transfer agent, and Galaxy is leveraging Chainlink NAVLink to publish the fund's daily NAV onchain and Chainlink CCIP for secure cross-chain interoperability. State Street Bank and Trust Company serves as the fund's custodian for securities holdings.

Announced in December 2025, SWEEP allows investors to use PayPal USD (PYUSD) stablecoins for subscriptions and redemptions, subject to portfolio availability, and is available to Qualified Purchasers that meet certain eligibility criteria and minimum investment amounts.

"State Street has played a leading role in market innovation for decades, from servicing mutual funds to launching ETFs, and we're proud to continue that role as digital assets reshape market infrastructure," said Yie-Hsin Hung, president and chief executive officer of State Street Investment Management. "This fund allows us to bring the TradFi landscape onchain in a resilient way, guided by our long-standing focus on innovation, risk management and client outcomes."

"For years we've argued that traditional finance and crypto would converge on the same rails," said Mike Novogratz, founder and CEO of Galaxy. "We believe SWEEP is what that looks like in practice, with a fund managed by an experienced cash manager being available for investors onchain, on infrastructure Galaxy built for institutions."

SWEEP expands and deepens State Street Investment Management's relationship with Galaxy. In September 2024, State Street Investment Management launched three actively managed ETFs sub-advised by Galaxy that are focused on digital assets and disruptive technologies.
