Expert Answers
Hardware Wallet Firmware Audit FAQs
Get clear, technical answers to the most common questions about our hardware wallet firmware security auditing process, methodology, and deliverables.
We employ a hybrid methodology combining automated static analysis, manual code review, and physical hardware testing.
Phase 1: Automated Analysis – We use specialized tools to scan for known vulnerabilities, memory safety issues, and cryptographic flaws in the C/C++/Rust codebase.
Phase 2: Manual Expert Review – Our senior security engineers conduct line-by-line reviews focusing on logic errors, side-channel attack vectors, secure element integration, and supply chain risks.
Phase 3: Hardware Validation – We test the firmware on reference hardware to verify secure boot, PIN/seed entry resistance to physical attacks, and fault injection resilience.
All findings are documented with CVSS scores, proof-of-concept exploits, and prioritized remediation guidance.
