Offline Mnemonic Drive
Military-grade Cold Storage
TRNG & Offline Storage
Hardware TRNG generates mnemonics inside secure chip, no OS/bluetooth/WiFi exposure, eliminating remote theft.
Active Defense
Nano intrusion sensors + voltage tamper detection triggers instant zero-delay data erasure.
Fire/Water IP68
Titanium alloy shell, 950°C for 60min, 3m underwater 72h, assets recoverable after disasters.
Why offline drive?
Screenshots, cloud notes, hot wallet flaws — $4.2B lost annually. Offline drive locks private keys inside physical device, blocking malware, SIM swap, phishing.
