What is Tangem?
Tangem is a cold wallet in the form of NFC cards or a ring, made by Tangem AG in Zug, Switzerland. You sign by tapping the card to a phone running the Tangem app. Its site lists 14,100+ tokens across 90 blockchains, and the iOS and Android app code is public on GitHub.
How Tangem works
A Tangem wallet is a set of two or three NFC cards, or a ring plus two cards.
By default the chip's hardware random number generator creates the private key inside the card, and during activation the key is copied to the backup cards over an encrypted link, with no other copies. When you send, the Tangem app passes unsigned transaction data to the card over NFC; the secure element signs it internally and returns only the signature. You can instead generate or import a seed phrase in the app, which Tangem notes can be copied and stolen.
The chip is CC EAL6+ certified, and Tangem says the Ring's firmware cannot be updated. Cure53, Riscure and Kudelski Security have reviewed parts of the stack, from the mobile app to smartcard code, and Tangem publishes an app changelog and runs a bug bounty. The ring has a zirconia ceramic shell rated IP69K. Tangem states the cards and ring are designed to last at least 25 years, and no Tangem servers take part in signing, so the wallet keeps working if the company disappears.
How to start with Tangem
- You need a phone with NFC and the Tangem app from the App Store or Google Play.
- Order a pack from tangem.com, open the app, tap your first card or ring to the phone, and follow activation, which Tangem says takes under three minutes.
- Set an access code and tap each backup card to copy the key.
- Keep one card with you and store the others apart.
- Tangem's support chat is listed as available 24/7.
Tangem fees and limits
- On September 26, 2026 the pricing page listed the 2-card set at $59.90, the 3-card set at $69.90, a Family Pack of two wallets at $129.80, the Ring with two cards at $160 and the Tangem Pro Kit at $180.
- Taxes and duties are extra, standard shipping is free on orders above $100, and there is no subscription.
The checkout accepts promo codes and the site was running a flash sale banner, so the price you pay can differ. Network fees and swap provider charges apply when you move funds.
Risks to know before using Tangem
- Recovery depends on your backup cards.
- Tangem's own FAQ warns that with a 2-card set, losing one card and forgetting the access code leaves you unable to reset or recover the wallet, which is why it recommends three cards.
- The cards have no screen, so you confirm transaction details only in the phone app; a compromised phone could display false details.
