Overview
Tangem is a card-shaped cold wallet you tap to your phone — no cables, no charging — which makes it the easiest cold storage to actually use.
Instead of a device with a screen, Tangem is a set of smart cards with a secure chip. You tap a card to your phone via NFC to sign transactions. It's remarkably approachable, though the backup model (holding two or three cards) is different from a traditional recovery phrase.
Key features
- Card format that taps to your phone via NFC — no cables
- A certified secure chip with a long stated lifespan
- A simple app for buying, swapping and managing assets
- Comes as a 2- or 3-card set for backup redundancy
Specs & compatibility
A one-off purchase (around $54 for a card set), among the cheapest cold-storage options. There's no charging or firmware updating to worry about. Buy directly from Tangem, and keep your backup cards in separate safe locations.
Security & trust
Tangem uses a certified secure element and keeps keys on the card. The unusual part is backup: rather than writing down a seed phrase, you keep multiple cards, any of which can access the wallet — convenient, but you must store the spare cards securely and not lose them all. You can optionally export a seed phrase.
