Undercover Design
It reads as a plain card. No logos that shout “crypto,” no markings that make you a target. Discretion is the default.

// Why Blocks Vault
Blockchain Security You Won't Have to Compromise
Four engineering principles built for holders who treat self-custody as non-negotiable.
Genuinely Offline
Your private keys never touch a network. The card stays fully air-gapped when idle, leaving no remote attack surface to exploit.
EAL6+ Certified
The chip meets one of the highest commercial assurance grades — the same tier trusted for electronic passports and secure IDs.
Tap & Confirm
A single tap talks to the companion app over NFC. No cables, no adapters, no clumsy pairing — just contactless simplicity.
// Built Different
Not Just Another Hardware Wallet
Every decision was made to defend you — not only from hackers, but from anyone who might single you out.
- Anti-Targeting by Default Zero visible crypto branding means you can carry it anywhere without flagging yourself as a holder.
- Storage-Only Architecture It can't swap, buy, or bridge on its own — intentionally. Your keys remain cold at all times.
- BIP39 Recovery Built In Full standard seed-phrase support lets you restore your assets on any compatible wallet, anywhere.
- Maintenance-Free Lifespan No battery to expire and no firmware to corrupt. Passive NFC keeps working for a decade or more.
