Use Cases

Reference implementations and integration patterns for common verification scenarios.

Regulated Markets Compliance

Trading and lending systems operating under securities and banking rules require identity and eligibility verification with a clear audit trail. FH Protocol issues deterministic Verification Records for KYC and eligibility attestations that integrate with institutional workflows.

Implementation Pattern

1. Subject completes KYC with a verified issuer
2. Issuer runs verification through FH Protocol
3. Subject receives a Verification Record
4. Counterparty systems validate the record against policy
5. Access follows governed institutional capability rules

Institutional Onboarding

Financial institutions can verify counterparty credentials without accessing underlying documents. Attestations are portable across institutions, reducing redundant verification processes.

Supported Credential Types

Accredited Investor: SEC Rule 501 qualification verification
Qualified Purchaser: Investment Company Act Section 2(a)(51) status
Institutional Investor: Regulated entity classification

Cross-Border Transactions

International transactions require verification of jurisdiction and sanctions compliance. FH Protocol attestations enable real-time compliance checks without exposing location data.

Jurisdiction Verification

Proves residence in permitted jurisdiction set without revealing specific country or address.

Sanctions Screening

Attests non-inclusion on OFAC and equivalent sanctions lists with daily refresh.

Tax Treaty Eligibility

Verifies eligibility for tax treaty benefits based on residence attestation.

Age-Gated Access

Applications requiring age verification can utilize FH Protocol attestations to confirm users meet minimum age requirements without collecting birth date information.
