Attestation-Led Compliance (EAS, ERC-1271, ERC-3643)

Introduction

Fairway enables institutions to enforce compliance on-chain in a privacy-preserving way. On EVM chains we use EAS attestations with:

• kyc_verified_at → when the KYC check was done (long-lived).

• sanctions_epoch → current counter for sanctions/risk list freshness.

• risk_profile_score → optional AML risk rating.

This lets dApps enforce jurisdiction-specific freshness policies without exposing PII.
