The Ultimate Bitcoin Hardware Wallet

Tangem cards let you secure and manage Bitcoin in a sleek and stylish card, maintaining self-custody and complete control of your funds. 

The Tangem Twin set elevates our hardware with a pair of cards, each programmed to access the same Bitcoin wallet enabling you to use either of two cards to sign and send Bitcoin transactions.

Designed for simplicity

Tangem Twin is powered with NFC-technology enabling you to access your wallet and manage your funds from our App by simply tapping the card on your phone.

Our App connects to third-party exchanges to purchase Bitcoin with fiat currency from your bank account, debit, or credit card.

Security

What determines the safety of your Bitcoin is the security of your private key storage.

Tangem’s chip generates and holds your unique and uncopyable key within the card itself, and no one can extract it or make a copy of it.

Tangem’s firmware is audited by Kudelski Security to ensure your protection.

Backup

1-of-2 Multi-Sig is a safety feature enabled by Bitcoin architecture which allows either of two keys, as stored safely and secretly in each card’s secure element, to independently sign a transaction to send money from the same wallet address. This way funds can be recovered in case one card is lost.
