FAQ
What does “military-grade security” mean in Bitcoin wallets?
Military-grade security refers to the use of certified secure elements (like CC EAL5+ or EAL7 chips), air-gapped architecture, tamper-proof hardware, and advanced recovery protocols. These features are designed to resist physical attacks, malware, and remote exploits—similar to standards used in defense and government systems.
Which wallet offers the highest security certification?
NGRAVE ZERO leads with an EAL7-certified secure element, the highest rating globally. It’s fully air-gapped, uses biometric authentication, and offers a metal recovery system (GRAPHENE), making it ideal for ultra-secure cold storage.
Are air-gapped wallets safer than USB-connected ones?
Yes. Air-gapped wallets like Keystone Pro, Ellipal Titan, and Coldcard Mk4 never connect via USB, Bluetooth, or Wi-Fi. They use QR codes or microSD cards for signing transactions, minimizing attack surfaces and preventing remote access.
Which wallet is best for mobile users?
Ledger Nano X and SafePal S1 are excellent for mobile-first users. Ledger supports Bluetooth and Ledger Live, while SafePal uses QR code signing and integrates with DeFi apps—all without compromising security.
