# Security & Compliance Notes

* **No PII on-chain** → only timestamps, epochs, risk flags.
* **Sanctions updates** → epoch increments automatically.
* **KYC timestamp** → dApps enforce jurisdictional freshness rules.
* **Smart wallets** → supported via ERC-1271 signatures.
* **Audit trail** → `commitmentRoot` links back to Midnight proofs.

{% hint style="info" %}
This model aligns with **FATF ongoing due diligence**, **AML directives**, and **GDPR** by separating long-term KYC validity from short-term sanctions updates.
