Protocol-impersonator domain registered (typosquat)

Circle USYC's assessment for RD-F-161 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Structural elevation factor for high-recognition brands (per process-learnings.md). Circle is a top-tier regulated brand ($CRCL NYSE IPO filed 2025; USDC issuer ~$42B market cap). Official USYC domains: circle.com (historical registration since 1994), hashnote.com (pre-acquisition), usyc.hashnote.com. Production pipeline DomainTools/WhoisXML API not available in this agent run - WHOIS lookup is a repeatable gap per process-learnings.md. Explicit 90-day registration-date delta (2026-02-15 to 2026-05-16) cannot be computed without a domain-monitoring feed. No specific documented typosquat incident for USYC/Circle in web OSINT search results. Elevated risk assessment based on brand recognition, $2.97B TVL, and recent BSC expansion to new institutional user base creating new typosquat attack surface.
