Offer fixed-scope laboratory audits that test wallet key generation across firmware versions and physical devices, followed by a signed findings report and remediation review. Add an incident-response package covering affected-device classification, safe migration procedures, evidence-preservation instructions, and ownership-verification workflows. Begin as an expert-led service and gradually productize the repeatable test harnesses and audit methodology.

A reported five-year flaw and active draining of weak wallets expose a visible gap between hardware wallet marketing claims and real-world key-generation assurance. Manufacturers, custodians, insurers, and large treasury holders now have a concrete reason to demand independent testing before trusting new firmware or devices.
