Overview
Tangem is a hardware wallet shaped like a regular bank card: same thickness, same size. It holds the keys to your crypto on a chip embedded in the card, and you sign transactions by tapping the card on your phone (the same way you'd pay with contactless). No cables, no charging, no buttons, no batteries1.
Tangem stands out from most other hardware wallets for two reasons. First, the form factor: a card slips into your wallet next to your bank cards. Second, the backup model: instead of writing down a recovery phrase on paper, you buy a set of two or three linked cards, and each card holds the same wallet. If you lose one, the others still get you in.
Key Features
- A wallet the size of a bank card. No USB cable, no charging, no batteries, no buttons. Just tap the card on your phone over NFC to sign a transaction1.
- Backup cards instead of a written phrase. A Tangem set comes with two or three identical cards. Losing one doesn't lock you out, because the other cards open the same wallet1.
- A chip used in passports. The chip inside the card is certified to the same security level used in biometric passports, with tampering safeguards built in by Samsung Semiconductors1.
- Stake ADA from the Tangem app. Open the app, pick a Cardano stake pool, tap the card, done. Rewards arrive every five days, and your ADA remains in your wallet on the Cardano blockchain2.
- Connect to apps on supported networks. Tangem supports WalletConnect connections for EVM networks and Solana3.
- One card, many coins. Holds Cardano, Bitcoin, Ethereum, Solana, and over 16,000 tokens across 90+ blockchains, not just ADA1.
What to Expect
Setting up Tangem takes about two minutes, genuinely. You tap the first card on the Tangem app, link the backup cards, and the chip generates a private key. There's no 24-word recovery phrase to write down by default (though you can choose to add one if you prefer). Each backup card holds the same wallet, so day-to-day you carry one card and keep the other in a safe place.
Sending ADA, receiving tokens, or staking happens through the Tangem app on your phone, with a card tap to sign. In seedless setup, the card generates the private key. Optional seed-phrase generation or import also involves the app4.
Tangem has no independent transaction screen: you review details on your phone before tapping the card. Cure53's November 2025 review covered the Android and iOS software development kits, the components used to build wallet applications. The published report describes that component-level review5.
The appeal is mostly about how unintimidating Tangem feels: a card you can carry in your physical wallet, set up in two minutes, with no jargon-heavy onboarding and no paper recovery phrase to lose.
