Tangem Stealth Cards

These tamper-resistant hardware wallets utilize a secure element chip and PIN protection to generate and store your private keys entirely offline. By keeping the keys isolated from the internet, they offer enhanced security against online threats like phishing attacks.

Tangem operates by distributing the private key across a set of cards using threshold cryptography. To recover your funds if one card is lost, you simply use one of the remaining backup cards from your original set.

The cards themselves contain no battery and draw power directly from your smartphone via near-field communication (NFC). While your phone needs an internet connection to broadcast transactions, the card only needs to be tapped against the device.

Yes, the Tangem app supports a wide variety of cryptocurrencies and tokens across multiple blockchains. This allows you to manage a diverse portfolio of digital assets using just one set of hardware cards.
