Tangem Wallet Review 2025: Card Hardware Wallet Analysis

What is Tangem Wallet?

Tangem Wallet is a revolutionary card-style hardware wallet that stores cryptocurrency private keys on a secure chip embedded in a credit card-sized device. Unlike traditional hardware wallets with screens and buttons, Tangem cards use NFC (Near Field Communication) technology to interact with your smartphone, making them one of the most portable and user-friendly cold storage solutions available for blockchain assets and DeFi interactions.

Founded in 2017, Tangem has gained recognition for its innovative approach to cryptocurrency security, combining the convenience of a payment card with the security of a hardware wallet. The company has partnerships with major blockchain projects and has issued millions of cards worldwide, supporting various consensus mechanisms and smart contract platforms.

Frequently Asked Questions

Is Tangem as secure as traditional hardware wallets?

Yes, Tangem uses bank-grade security chips (CC EAL6+ certified) that provide equivalent or superior security to traditional hardware wallets. The main difference is the lack of a screen for transaction verification.

What happens if I lose my Tangem card?

If you have backup cards, you can access your cryptocurrency funds immediately. Without backup cards, your digital assets are permanently lost since Tangem doesn't use seed phrases for recovery.

Can I use Tangem with DeFi protocols?

Yes, but with limitations. Tangem supports basic DeFi interactions through WalletConnect for yield farming and liquidity mining, but it has fewer smart contract integrations compared to Ledger or Trezor.

Do I need an internet connection to use Tangem?

You need the internet to check balances and broadcast transactions, but the card itself works offline for signing transactions.

How many backup cards should I get?

We recommend at least 2-3 cards total (1 primary + 1-2 backups) stored in different secure locations.
