Summary
The fund structure reflects a hybrid operational model pairing blockchain-native mechanics with institutional-grade custody. SWEEP initially launched on Solana, with planned expansion to Stellar and Ethereum, accepting subscriptions and redemptions in PYUSD (PayPal USD) with future USDC support. The fund imposes a $5 million minimum for institutional entities and $1 million for individuals, with a target expense ratio of 0.50% annually. Its restriction to qualified purchasers aligns with regulatory frameworks governing digital asset offerings to sophisticated investors.
The supporting infrastructure underscores the complexity of tokenized Treasury products. Anchorage Digital provides digital asset custody, while State Street Bank and Trust Company handles traditional securities custodianship—a dual-custody arrangement mirroring institutional requirements for both onchain and offchain asset safeguarding. NAV Consulting manages transfer agency services, and Chainlink supplies cross-chain data and messaging capabilities, enabling seamless asset movement across multiple blockchain networks.
The SWEEP launch builds on a relationship formalized in December 2025 when State Street and Galaxy first announced their collaboration. The partnership evolved from prior joint work on digital asset ETFs in 2024, reflecting a deliberate institutional strategy to expand tokenized product offerings. Yie-Hsin Hung, CEO of State Street Investment Management, characterized the launch as bringing "the TradFi landscape onchain," emphasizing resilience and accessibility. Galaxy CEO Mike Novogratz framed SWEEP as a convergence of traditional finance and crypto ecosystems aimed at enhancing cash management productivity, positioning the fund within a broader institutional adoption narrative around tokenized liquidity infrastructure.
