NEUS is the verification layer for identity, ownership, and agent authenticity. Verify once, trust everywhere.
  • Portable proof receipts — Get a qHash you can reuse across apps, gates, and agents
  • Gate content — Check eligibility before serving protected content
  • Sponsor flows — Apps cover verification cost for frictionless onboarding
  • Agent delegation — Verifiable agent identity and payment scopes
