▸ How trust tiers work
  • KYC verified — Referee identity confirmed by a government-grade KYC provider. Highest trust.
  • LinkedIn verified — Referee authenticated via LinkedIn, identity bound to a public professional profile.
  • Corporate email verified — Referee confirmed from a corporate-domain email.
  • Personal email verified — Referee confirmed from a personal email account. Standard tier.

All tiers go through the same cryptographic anchoring on Polygon — the tier describes identity confidence, not credential integrity.
