Security Guide
The Only Cold Storage Wallet Guide You Need
If your crypto lives on an exchange, you don't own it — you own an IOU. Cold storage puts private keys on hardware that never touches the internet. We tested and researched nine wallets so you don't have to spend three weekends in Reddit threads.

Our Take
Three scenarios, three recommendations.
₿
Bitcoin-only, max security
Coldcard Mk4 or Foundation Passport
Both are air-gapped, open source, and battle-tested. Coldcard if you want raw control. Passport if you want a friendlier setup.
🛡️
Multi-coin, air-gapped
Keystone Pro or ELLIPAL Titan 2.0
Keystone is open source; ELLIPAL has broader coin support but closed firmware. Both stay offline via QR.
🟢
Beginner-friendly
Trezor Safe 3 or Ledger Nano X
Trezor Safe 3 gives you EAL6+ security at $59 — unbeatable value. Ledger Nano X if you need Bluetooth and maximum coin support.
