Why Users Choose Tangem
Card-Based Hardware Wallet
Tangem takes the form of a smart card rather than a traditional hardware wallet device. The private key is generated and stored within the card's secure chip and never leaves it.
NFC Phone Interaction
Tangem cards communicate with a smartphone via NFC. Users tap the card against their phone to sign transactions, without connecting any cables or powering on a separate device.
No Cables or Battery
Because the Tangem card is passive and powered by the phone's NFC field during use, it requires no cables, charging, or battery management.
Mobile-First Experience
Asset management is handled through the Tangem mobile app, available for iOS and Android. The app provides the interface for viewing balances and initiating transactions that the card then signs.
Multi-Network Asset Management
Tangem supports a range of networks and crypto assets, allowing users to manage holdings across multiple blockchains through the mobile app and card signing workflow.
Self-Custody
Tangem is a self-custody solution. Private keys are stored in the card's secure chip and never transmitted to Tangem or any external server. Users retain direct control over their assets.
Tangem Wallet Overview
Tangem is a hardware wallet that takes the form of an NFC-enabled smart card rather than a traditional device with a screen and buttons. The private key is generated inside the card's secure chip during setup and never leaves the hardware. To sign a transaction, the user taps the card against a smartphone running the Tangem app, which handles the asset management interface while the card handles offline signing.
Because Tangem is a self-custody solution, private keys are stored solely within the card and are not transmitted to Tangem or any external service. The card requires no cables or battery, as it is powered passively by the phone's NFC field during use. Tangem supports a range of networks and crypto assets, manageable through the companion mobile app for iOS and Android.
Users who hold assets with a Tangem card and want to move them between different cryptocurrencies without using a centralized exchange may find non-custodial swap services a practical complement to their hardware wallet setup. Baltex provides direct swap routes across multiple asset pairs without requiring account creation or holding assets in custody.
