Hashnote

• Name: Hashnote
• URL: https://www.hashnote.com/
• Category: regulated tokenized-Treasury operator / digital-asset asset manager / yield-bearing collateral and cash-management company
• Tags: ethereum-ecosystem
• Summary: Hashnote belongs in companies/ because the durable dependency is a named operator that admits investors, screens wallets, controls allowlisting and entitlement rights, runs the teller subscribe/redeem workflow, structures the fund behind USYC, and now sits inside Circle’s broader dollar-rails shell. The useful question is not just how does USYC work onchain? but which operator decides who can hold it, who can redeem it, how the fund and custody workflow are packaged, and how that stack plugs into institutional collateral markets?
• What it does:
  • Operates a regulated asset-manager stack centered on USYC, the onchain representation of Hashnote International Short Duration Yield Fund Ltd., holding short-duration U.S. Treasuries plus repo and reverse-repo positions
  • Runs institutional onboarding with KYC/AML, wallet screening, allowlisting, and eligibility restrictions for non-U.S. institutions
  • Controls a teller-style subscribe and redeem workflow where approved users move between USDC and USYC under company-managed access rules and daily NAV-based pricing
  • Uses a permissioned ERC-20 model with entitlement roles, sanctions screening, and transfer restrictions rather than a free-floating bearer asset model
  • Packages USYC as yield-bearing collateral for exchanges, custodians, and prime brokers, not just as a retail treasury token wrapper
  • Now sits inside Circle’s post-acquisition operator shell, which matters because Circle can combine the fund with USDC distribution, settlement, and collateral-routing workflows
• Key claims:
  • Hashnote’s homepage describes the company as a regulated asset manager providing customizable digital-asset exposure with blockchain-based transparency and real-time audibility
  • The USYC docs say USYC is the onchain representation of Hashnote International Short Duration Yield Fund Ltd. and is available only to eligible institutions outside the United States with a US$100,000 minimum investment
  • The docs describe a workflow where onboarded investors subscribe with USDC, redeem back to USDC through the Teller, and receive pricing based on daily NAV reporting
  • Product-structuring and onboarding materials describe USYC as a permissioned ERC-20 whose holders and transferees must be allowlisted and entitled, with sanctions checks and other controls built into the system
  • Circle’s January 2025 acquisition announcement frames USYC as the largest tokenized money market fund at that time and emphasizes its role as preferred yield-bearing collateral across digital-asset markets
• Whitepaper: No standalone company whitepaper is the important artifact here. The clearest primary materials are Hashnote’s official site, the USYC documentation corpus, and Circle’s acquisition announcement; the broader source bundle remains ../whitepapers/hashnote-primary-sources-2026-04-26.md.

Internal linkages

• Alias note for legacy project placement: hashnote.
• Useful adjacent company / issuer reads: circle, opentrade, and paxos.
• Useful adjacent operator / issuer comparison when the question is who packages the fund, custody, and redemption shell around tokenized Treasury exposure: openeden.

Protocol / company boundary

• Hashnote is better kept as an entity note than as a standalone projects/ note because the practical dependency is a named operator running investor admission, allowlisting, entitlement management, redemption workflow, fund structuring, and collateral-market packaging.
• There is no especially useful neutral Hashnote protocol boundary doing separate work here. USYC’s smart-contract surface matters, but it only becomes usable through the company-run compliance, teller, and fund-administration shell.
• Keep [[../projects/hashnote]] only as an alias so legacy links continue to resolve without pretending Hashnote is a protocol peer to more autonomous onchain systems.

Control surface

• Practical leverage sits in investor eligibility, wallet whitelisting, sanctions screening, entitlement issuance, teller access, subscribe/redeem workflow, custody and fund-service-provider composition, and the post-acquisition way Circle can package USYC alongside USDC and related collateral flows.

• Read Hashnote here as a regulated operator boundary around a permissioned yield-bearing collateral product, not as a neutral token primitive.
