The Tangem app is fully available in English, French, German, Japanese, Russian, Spanish, and Ukranian and partially in Italian and Traditional Chinese.

Your funds are stored on the blockchain, and the wallet keeps the private keys to these funds. Without an internet connection, you cannot access the blockchain, check your current balance, or initiate transactions. However, you can still top up or deposit funds into your wallet.

Yes, you can mine directly to your wallet. There are no restrictions for mining in UTXO-based blockchains (for example, Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Dash, Kaspa, Ravencoin) on Android OS, since the wallet can sign thousands of inputs.
However, on iOS there is a limit of 700 inputs per minute.

In account-based blockchains (Ethereum Classic, DisChain (Ethereum Fair), Ethereum PoW and more) there is no concept of inputs, and accordingly, there are no mining restrictions on the Tangem Wallet.

To access the Tangem app, you can use biometric authentication (fingerprint or facial recognition) instead of entering an access code and scanning a wallet. This allows you to view balances and switch between wallets if you have more than one.

To activate this feature, follow these instructions:
1. Open the Tangem app.
2. Click on the three dots in the upper-right corner of the homepage.
3. Select App settings.
4. Enable Keep the wallet in the app and Save access code.

When you enable Keep the wallet in the app, all Tangem wallets (if you have several) will be linked to the app, and you can access them with biometric authentication.

When you enable Save access code, all access codes will be stored in encrypted format on your phone’s secure enclave.
Then you can use biometric authentication instead of an access code when signing transactions with the wallet.

Important: Signing any transaction or making important changes will require your Tangem device.

When using biometric authentication, the access code from the card is stored in encrypted form in the device’s Secure Enclave (iOS) or Trusted Execution Environment (for Android OS). Biometric authentication is optional and can be disabled at any time or not enabled at all. For more information, you can refer to our blog article: How biometric authentication works in Tangem Wallet.

By default, the Tangem app displays the prices of your assets in US Dollars (USD). However, you can change the currency to see how much they are worth in another fiat currency. To do this, follow these instructions:
1. Open the Tangem app.
2. Tap the three dots in the upper right corner of the homepage.
3. Select App settings, then App Currency.
4. Find the currency you need in the search bar, scroll down the list of currencies, and select one.
The app will display the prices of cryptocurrencies and your wallet’s balance in the chosen currency.

Flip your device face down to hide/show balance.

To enable/disable this feature, follow these steps:
1. Open the Tangem app and log in to your wallet.
2. Tap the three dots in the upper right corner of the main screen.
3. Select App settings.
4. Enable Flip-to-hide Balances.

Hiding your balance provides additional privacy by preventing others from seeing your financial information. In crowded places, the balance hiding feature can protect you from strangers trying to snoop on your wallet details. It will also help prevent other people from making assumptions and judgments about your financial situation.

How the hide balance feature works
Android and iOS devices feature built-in motion sensors, including an accelerometer and a gyroscope, enabling developers to capture movement along a three-dimensional axis.
This feature makes it possible to recognize various user movements, such as tilting the phone, shaking it back and forth, and rotating it in a circle.
We’ve taken advantage of this feature to provide you with a convenient way to swiftly hide your portfolio’s value.

You can manage multiple Tangem wallets in one app.

Tangem Wallet itself does not have a built-in tax reporting feature. However, you can easily generate tax reports for your Tangem Wallet transactions by using third-party crypto tax software like CoinLedger.

When preparing tax returns, you often need to use third-party services that can help you automate the process and provide detailed reports after connecting your cryptocurrency wallet. One of the most convenient ways to do this is to use an extended public key (xPub).

What is an xPub key?
The extended public key (xPub) is the master key of the account from which all public addresses are generated. It allows third-party services to obtain transaction information without needing access to your private key, keeping your wallet secure.

How do I get an xPub key in the Tangem app?
To get an xPub key, follow these steps:
1. Open the Tangem app and log in to your wallet.
2. Go to the token page by clicking on it on the main screen.
3. Tap the three dots in the upper right corner.
4. Select Generate XPUB.
5. Enter your access code and scan your Tangem.

xPub key generation is available for most blockchains, including UTXO-based blockchains (Bitcoin, Bitcoin Cash, Dash, Dogecoin, Kaspa, Litecoin, Ravencoin) and EVM-compatible blockchains (Ethereum, BNB Smart Chain, Arbitrum, etc.

Export transaction history
There is currently no option to export transaction history in the Tangem app. However, some blockchains allow you to export your transaction history in a CSV file on their website.

To go to the blockchain explorer, follow these steps:
1. Open the Tangem app and log in to your wallet.
2. Tap on the desired cryptocurrency on the main screen of the Tangem application.
3. Find the View Transaction History (or Explorer) option and click on it.
4. This will take you to your wallet’s public address in the browser. In the blockchain browser, you can find and export your transaction history for further use in tax reporting.

To change the theme in the app, follow these steps:
1. Open the Tangem app and log in to your wallet.
2. Click on the three dots in the upper right corner.
3. Select App settings.
4. Select Theme.
5. Select light theme, dark theme, or system default.

When you select System default, the app will use a theme based on your phone’s settings.

The Tangem app automatically closes after 5 minutes. If you minimize the app and return within this 5-minute window, you won’t need to scan your wallet or use your biometrics. However, if you completely close the app, it will prompt you for a device scan or biometrics each time you reopen it, even if it’s within the 5-minute period.
