Tangem
Tangem is a crypto wallet that offers hardware-based key storage in NFC cards and rings, as well as a standalone mobile version that does not require a physical device. The Tangem hardware wallet works with a smartphone: the card is held up to the NFC module, and transactions are viewed and confirmed through the proprietary app. The device has no battery, no display, and no constant internet connection, and the private key remains inside a secure chip.
In 2026, Tangem expanded its lineup with the software-based Tangem Mobile Wallet. It is created directly within the app, without the need to purchase a card or ring. In the mobile version, the keys are protected by the smartphone’s security features, whereas the hardware wallet uses a separate physical medium. These are two different storage methods, and they should not be confused in terms of their level of isolation.
Tangem Hardware Wallet: NFC and Backup Devices
To fully set up Tangem Wallet 2.0, a set of two or three cards or compatible devices is typically used. During the backup process, the cryptographic key is securely transferred to the selected additional devices. All cards in the set are equivalent: if one is lost, the remaining ones continue to provide access to the same wallet. You cannot add a third card to an already completed backup without reconfiguring the wallet.
- Physical devices are available as NFC cards and rings.
- A compatible NFC-enabled smartphone is required for operation.
- The hardware wallet can be set up with or without a seed phrase.
- A backup set of two or three devices protects against the loss of a single card.
- The app is available on iOS and Android, but hardware mode requires NFC.
Recovery Methods
When setting up a Tangem hardware wallet without a seed phrase, the key is stored on the devices in the backup set. Losing all linked cards means losing access to this key: support cannot create a new backup without a remaining device. Therefore, it is recommended to store the cards in different secure locations rather than carrying them all together. The seed phrase option provides a different recovery scenario but requires the phrase itself to be stored securely.
Tangem Mobile Wallet uses a recovery phrase and stores private keys in the phone’s secure environment. With this option, physical cards and NFC are not required when managing assets. The mobile wallet can be switched to hardware mode using Tangem devices; once the transfer is complete, the key is transferred to secure chips. For this transition, you must prepare backup devices in advance and ensure that recovery data is available.
Coins, Networks, and Fees
The app supports Bitcoin, Ethereum, USDT, and other supported digital assets. USDT is issued on several networks, so before sending, you must select a specific blockchain, verify the address, and ensure you have enough coins to cover the network fee. When sending assets, fees are determined by the rules of the respective blockchain. The app allows you to select fee settings where supported by the network.
Exchanges within Tangem are carried out through integrated external providers. The final exchange rate takes into account the provider’s fee, network fees, and the spread between the buy and sell prices. Exchanging certain tokens may require additional smart contract authorization. Basic cryptocurrency storage does not require a subscription, but the cost of the physical devices themselves, shipping, and any partner fees are paid separately.
Use in Russia
Hardware wallet technology is not tied to any specific Russian bank. However, purchasing cryptocurrency with rubles, selling it for fiat currency, and transferring funds to a card are handled by third-party payment services. Their availability depends on the country, bank, currency, and identity verification requirements. The availability of Tangem does not automatically mean support for withdrawals to a Russian card. When purchasing a set of devices, consider the seller’s reliability and delivery options.
Frequently Asked Questions
Do I need a seed phrase for Tangem?
The Tangem Wallet 2.0 hardware wallet supports setup without a seed phrase using backup cards, as well as an option that uses a seed phrase. The Tangem Mobile Wallet app uses a recovery phrase.
Can I use Tangem without purchasing a card?
Yes. The Tangem Mobile Wallet functions as a non-custodial software wallet on a compatible smartphone, but does not provide hardware-based key isolation.
What happens if I lose one Tangem card?
The remaining backup card from the linked set will preserve access to your funds. If all devices are lost and there is no other recovery data, access cannot be restored.
Can I withdraw USDT to a bank card via Tangem?
Selling and withdrawing to fiat depend on the third-party payment provider, the selected asset, and the region. The hardware wallet itself is not a banking withdrawal instrument.
Editor’s Opinion
Tangem stands out for its unique hardware wallet design: the card or ring doesn’t require charging, a separate cable, or a large screen. This option is convenient for those who want to store cryptocurrency outside their smartphone but don’t plan to constantly deal with complex DeFi transactions on a computer. The key to security is a well-organized backup set. You need two or three cards not for convenience, but to restore access if you lose your device. The Tangem Mobile Wallet deserves special attention: it lets you get familiar with the interface without buying any hardware, though it remains a software wallet. When choosing Tangem, you should focus on the key storage format, NFC support, and the reliability of the backup system, rather than on the availability of buying and selling features through partners.
