Hardware Validation of ERC-3643 Regulated Security Tokens

Engineering cryptographic verification of investor identity claims, transfer restrictions, and jurisdictional compliance.

The ERC-3643 Permissioned Token Standard

ERC-3643 ensures that tokens can only be transferred between wallets that have passed verified identity checks (ONCHAINID). EquityHSM evaluates these compliance rules inside the hardware enclave before generating approval signatures, preventing illegal secondary trading.

Cryptographic Compliance Proofs

By checking zero-knowledge identity claims, EquityHSM verifies investor accreditation and tax residency without revealing personally identifiable information (PII) on public blockchains, fulfilling GDPR requirements.

Identity Claim Verification: Verifying ONCHAINID verifiable credentials before signing any token transfer.
Jurisdictional Transfer Rules: Enforcing investor count limits (e.g. US Reg D 2,000 investor ceiling) in hardware.
Automated Investor Accreditation: Validating accredited investor expiration timestamps within secure enclave memory.
Transfer Agent Governance: Enforcing forced-transfer and asset recovery primitives under court-order authorizations.
