Fund Transfers

• Where can I view my transaction history?

  Currently, the transaction history in the app is available for the Bitcoin, Ethereum, Avalanche C-Chain, BNB Smart Chain, Dash, Dogecoin, Ethereum Classic, Ethereum PoW, Litecoin, and Tron blockchains.
  
  Transaction history can be viewed in the blockchain explorer and is also used for other blockchains. Here’s how to do this:
  1. Open the Tangem app.
  2. Click on the coin/token you are interested in.
  3. Scroll down and tap Explore transaction history. You will be redirected to the blockchain explorer.

• How do I transfer cryptocurrency from an exchange/wallet to Tangem?

  You can transfer cryptocurrencies supported by the Tangem app to your wallet address. To do this, you'll need to generate a recipient address in the Tangem app.
  
  

  Here's what you need to do:

  1. Open the Tangem app and go to the homepage.
  2. Tap the three dots in the top right corner.
  3. Select the desired wallet.
  4. Go to the "Manage tokens" section.
  5. Find the cryptocurrency using the search bar.
  6. You will see a toggle button to the right of the cryptocurrency. Tap on it, and the list of available networks will appear.
  7. Turn on the toggle of the network you want and tap the "Save". You may need to scan your Tangem Wallet again.

  Important! Ensure that the sender and recipient networks match when performing a transfer. Many tokens function simultaneously on different networks. If the transfer is made through a different network than the sender's network, the coins may be lost and cannot be recovered.

  8. Once the token has been added to the homepage, tap on it, click "Receive", and you'll see the public address below the "Copy" button.
  
  

  Note that the network you select for the token in step 7 must match the transfer network you choose on the exchange.

  
  

• How do I choose the correct network for transferring funds to Tangem Wallet?

  Only cryptocurrencies supported by the Tangem app can be transferred into your wallet. To see the complete list of supported cryptocurrencies, go to the "Manage tokens" section of the Tangem app.
  
  

  Here’s what to do:
  1. Open the Tangem app.
  2. Tap the three dots in the top right corner.
  3. Select the preferred wallet.
  4. Go to the "Manage tokens" section. You can find the cryptocurrency you want by using the search bar in the list of tokens.
  5. Tap on the arrow next to the name of the cryptocurrency to see a list of available networks for the chosen token. You can use any of the listed networks.
  
  

  When making a transfer, you must ensure that the sender and recipient networks match, as many tokens operate on different networks simultaneously. If the transfer is made through a network other than the one the recipient specified when generating the address, the coins may be lost and cannot be recovered.

• How do I transfer cryptocurrency, if the wallet doesn’t support the required network?

  If you can't find the token you need in the tokens list in the "Manage tokens" section, you can add a custom token to the wallet yourself.
  
  This feature is available for the following networks: Arbitrum, Areon, Aurora, Avalanche C-Chain, BNB Beacon Chain, BNB Smart Chain, Base, Blast, Canxium, Casper, Cardano, Cronos, Cyber, Decimal Smart Chain, DisChain (Ethereum Fair), Ethereum, Ethereum Classic, Ethereum PoW, Fantom Opera, Flare, Gnosis Chain, Hedera, Kava EVM, Manta Pacific, Mantle, Moonbeam, Moonriver, OctaSpace, Optimistic Ethereum, PLAYA3ULL GAMES, Polygon, Polygon zkEVM, PulseChain, RSK, Shibarium, Solana, Telos, Tron, VeChain, XDC Network, zkSync Era.
  
  If the required network/token is not in the "Manage tokens" section or in the above list, then this token/network is not yet supported by the wallet, and it cannot be transferred to wallets.
  
  To create a custom token, do this:
  1. Open the Tangem app.
  2. Tap the three dots in the top right corner.
  3. Select the preferred wallet.
  4. Go to the Manage tokens section.
  5. Tap the “+” icon in the upper right corner of the list of tokens.
  
  To add a token, you need the following inputs:
  1. The token's smart contract address. The address can usually be found on coinmarketcap.com or in the explorer (browser) of the corresponding blockchain.
  2. The network where you want to add the token. 
  3. The token name (for example, Bitcoin) and token symbol (for example, BTC).
  4. Decimals determine the value into which one token can be split for transactions. This value can be found in the token overview in the explorer of the corresponding blockchain.
  5. BIP44 coin type. For this operation, "Default" is usually selected.
  
  For example, to add the BinaryX (BNX) token on the BNB Smart Chain network, you need to fill in the fields as follows:
  1. Contract address: 0x8C851d1a123Ff703BD1f9dabe631b69902Df5f97 You can see this contract address in the “Contracts” section via the link.
  2. Network: BNB Smart Chain.
  3. Token name: BinaryX.
  4. Token symbol: BNX.
  5. Decimals: 18. You can see the number of decimal places in the token card in the explorer.
  6. BIP44 derivation: Default.
  
  Detailed instructions are also available on our blog.
  
  

• What do I do if I transferred XRP to Tangem Wallet, but the amount of XRP I received was 1 less than expected? What if I transferred XLM to Tangem Wallet, but received 1 less XLM than I should have?

  The XRPL and Stellar blockchains use the concept of accounts. To open an account on XRPL you need to deposit at least 1 XRP, while the minimum on Stellar is 1 XLM. When you open an account, these funds are reserved and remain unavailable for withdrawal. For example, if you deposit 10 XRP, 1 XRP will be reserved for creating an account, and the balance will show 9 XRP available to spend.

• What does "Account is not created" mean in the XRPL/Stellar wallet?

  The XRPL and Stellar blockchains use the concept of accounts. To open an account on XRPL you need to deposit at least 1 XRP, while the minimum on Stellar is 1 XLM. When you open an account, these funds are reserved and remain unavailable for withdrawal. For example, if you deposit 10 XRP, 1 XRP will be reserved for creating an account, and the balance will show 9 XRP available to spend.

• What Tag/Memo should I specify when transferring tokens to Tangem Wallet?

  Destination tag/Memo/Message is an additional address value in numeric and/or string form. It allows identifying the recipient of an XRP/XLM/ATOM/TON/LUNA/LUNC/ICP transfer on a centralized exchange (e.g., Binance, Coinbase).
  
  You do not need to specify a destination tag when sending XRP/XLM/ATOM/TON/LUNA/LUNC/ICP coins from an exchange to Tangem Wallet. Since you are the one in control of this address, the coins will automatically appear in your Tangem Wallet.
  
  That said, some exchanges still offer to specify a tag when withdrawing coins. In this case, you can specify any value of the tag — for example, any number or digit. None of these numbers are needed to get your coins.

• What should I do if I sent funds to an exchange but forgot to indicate the memo/tag?

  Contact the exchange’s support team if you forgot to specify a memo or tag when transferring cryptocurrency to that exchange. They usually have a procedure for such cases.
  Provide them with all the necessary details about your transfer, such as the transaction number, transfer amount, and any other information to help them identify your transaction. The exchange can help restore the transfer according to their policies and capabilities.
   
  To find your transaction details, follow these steps in the app:
  1. Select the token involved in the transfer from the home page.
  2. Tap on Explore Transaction History or Explore. This will take you to your wallet's public address in the explorer.
  3. Scroll through the list of transactions until you find the one you want.
  4. Click on a transaction to view its details.

• Why am I credited in WETH when withdrawing ETH from an exchange?

  WETH (Wrapped Ethereum) is ETH stored outside its native network. If you send ETH on any network other than Ethereum, the tokens will arrive as WETH in Tangem Wallet.

• How do I find out my wallet address?

  To get your wallet address, open the Tangem app, select the token from the wallet homepage, and tap Receive.
  
  

  If the token is not on your wallet’s homepage, follow these steps in the Tangem app:
  1. Open the app and log in to your wallet.
  2. Tap the three dots in the top right corner.
  3. Select the desired wallet.
  4. Go to the "Manage tokens" section.
  5. Use the search bar to find the cryptocurrency you need.
  6. You'll see a toggle button next to the cryptocurrency name. Click it to see a list of available networks.
  7. Turn on the network you require and tap "Save". You might need to scan your wallet at this point.
  8. Once the token is added to the main page, click on it, select "Receive", and you will see the public address and a Copy button.
  
  

  Important! When transferring crypto, ensure that the sender and recipient networks match each other. Many tokens operate on different networks simultaneously.

  If a transfer is made using a different network than the recipient specified when generating the address, the coins may be lost and cannot be recovered.

• Does the wallet address stay the same for the entire time it’s used? Can I create multiple addresses for one token?

  All cryptocurrency wallet addresses remain unchanged. Public and private keys are changed only when you reset the card to factory settings and create a new wallet.

• Why are the addresses of different tokens the same?

  Token addresses on the same network and addresses on all EVM-compliant blockchains are the same in order to facilitate the convenient transfer of funds.

• What is the fee for transferring funds?

  Tangem does not charge any fees when transferring funds. Only a network commission is paid.

  This is a transaction fee that is paid to miners or validators. The fees vary depending on the network you use. For example, a Bitcoin transaction will have a different fee in comparison to transactions placed on the Bitcoin Cash, Ethereum or Litecoin networks. Fees can fluctuate depending on market demand and network capacity.

• How are fees charged on the Arbitrum network?

  Arbitrum One (ETH) is Ethereum on the Arbitrum network, which is its native coin. When you perform transactions on the Arbitrum network, the fees are charged in Arbitrum One (ETH) rather than the specific token you are transferring.

  
  To top up the balance in your Arbitrum One (ETH) wallet, you can purchase ETH in an exchange and then transfer the tokens to your wallet on the Arbitrum network.

• How are fees charged on the Base network?

  Base (ETH) is Ethereum on the Base network and is also its native coin. When you perform transactions on the Base network, the fees are charged in Base (ETH) rather than the specific token you are transferring.

  
  To top up the balance in your Base (ETH) wallet, you can buy ETH from an exchange and then transfer the tokens to your wallet on the Base network.

• How are fees charged on the Optimistic Ethereum network?

  Optimistic Ethereum (ETH) is Ethereum on the Optimistic Ethereum network, which is its native coin. When you perform transactions on the Optimistic Ethereum network, the fees are charged in Optimistic Ethereum (ETH) rather than the specific token you are transferring.

  
  To top up the balance in your Optimistic Ethereum (ETH) wallet, you can purchase ETH from an exchange and then transfer the tokens to your wallet on the Optimistic Ethereum network.

• How do I choose a network fee?

  When sending crypto assets, the network fees you offer determine your priority in the queue of pending transactions. Miners will prioritize transactions that offer high fees. Choose high fees if you require fast confirmation or lower fees if you can wait a while to save on fees.
  Tangem offers three fee levels depending on the current network load: low, normal, and priority.

• How do I find out the network fee for a token transaction?

  The size of the fee is displayed in the token sending window. Enter the destination address and transfer amount, and you will see the network fee.

• Why is the "Send" button inactive?

  If the "Send" button is disabled, it means that you do not have enough funds to cover the network fee. Please note that fees are charged in the network's native coin, not the specific token you are transferring. For instance, for BNB Smart Chain tokens (BEP-20), the fee is charged in BNB, and for TRON tokens, the fee is charged in TRX, and so on.

• What should I do if there are insufficient funds for paying network fees in my wallet?

  When transferring tokens on a network, transaction fees are charged in the network's native coin, not the token you are transferring. For example, if you're transferring BNB Smart Chain tokens (BEP-20), the commission will be charged in BNB, and if you're working with TRON tokens, the commission will be charged in TRX, and so on. Therefore, you need to have enough of the network's native coin to pay the fee to successfully complete a transaction, even if you are transferring other tokens.

• What does rent on the Solana network mean?

  This is the type of commission used on the Solana blockchain. The Solana network charges a rent of 0.000002439 SOL every two days. Accounts that can't afford the rent are purged from the network. Deposit more than 0.00089088 SOL to your account to use it for free.

• How do I buy cryptocurrency? How do I top up my Tangem Wallet using a bank card?

  The Tangem app allows you to buy cryptocurrency directly with your bank card via the integrated Mercuryo service.
  
  To do this, you should open the Tangem app and log into the wallet. Then, on the main screen, choose the required cryptocurrency and tap the "Buy" button. After this, you will be redirected to the Mercuryo service. Detailed step-by-step instructions on buying cryptocurrency with a bank card through Mercuryo can be found via the link.
  
  Terms of purchase (available fiat currencies, supported cryptocurrencies, minimum/maximum limits, commissions, payment methods and non-operational countries) can be found on the Mercuryo website.

• Card payment fails when buying cryptocurrency through Mercuryo. What do I do?

  If you encounter issues with payment by card when buying cryptocurrency through Mercuryo, please note that the problem lies with Mercuryo. Cryptocurrency purchases in the app are facilitated by a third-party service provided by Mercuryo. For assistance, you can utilize the live chat feature in the lower right corner of Mercuryo's website, or email Mercuryo support at support@mercuryo.io.

  
  We are looking to introduce more providers in the future. Meanwhile, you can consider alternative methods for purchasing cryptocurrency, such as acquiring it on a centralized exchange (CEX) and then transferring it to your Tangem wallet.

• What is the fee when buying cryptocurrency using a bank card?

  Buying cryptocurrency in the Tangem app is carried out through the Mercuryo partner service. Accordingly, the commission is set by Mercuryo, not Tangem. You can read more about the commissions for buying cryptocurrency using a card on the Mercuryo website via the link.

• What do I do if I can't send a transaction?

  If you face an error when sending cryptocurrency from Tangem Wallet, please send a request in the Tangem app in the "Can't send transaction" window by tapping on the "Contact support" button.

• How do I send cryptocurrency from Tangem Wallet?

  You can send cryptocurrency from your wallet in the Tangem app to a recipient address of your choice.
  To do this:
  1. Open the Tangem app by scanning your card and entering your access code.
  2. Select the cryptocurrency you want to send on the main screen.
  3. Tap the "Send" button.
  4. In the sending window, specify the recipient's address. Be sure to verify the copied and pasted addresses.
  5. Next, specify the amount to send or its counter value. You can tap the "Maximum amount" button to empty the address.
  6. You can change the fee level in the "Network fee" field. The default setting is "Normal".
  7. Verify all the inputs before you press the "Send" button.
  8. To sign the transaction, scan the card, enter the access code and scan the card again.
  After that, the transaction will be successfully signed and sent to the blockchain. The balance will be updated after some time.
  You can track the status of the transaction through the Explorer feature. To do this, go to the wallet overview in the Tangem app by tapping on the required cryptocurrency on the main screen and select "Transaction history".

• Why am I getting an "Invalid Address" error on the exchange/wallet?

  The error message "invalid address" indicates a possible mismatch in the selected token network.
  Please pay attention to which token network you choose, both on the exchange and in the Tangem wallet.
  
  If the networks are different, this may result in an "invalid address" error. It is essential to ensure that the sender and recipient networks match, as many tokens operate on different networks at the same time.

• Why didn't I receive the cryptocurrency sent to my wallet?

  There could be several reasons why funds sent to your Tangem Wallet have not arrived. Let’s review the most common ones:

  
  1. The transaction has not been processed by the blockchain. Check the transaction ID (txID or hash) in the blockchain explorer where the transfer was made. If the transaction is still unconfirmed, you need to wait for it to be processed.

  The transaction processing time depends on the blockchain (network) used. The network load and the fee set by the sender affect the processing speed.
  A delay might be caused by the sender setting a low transaction fee, which doesn't incentivize blockchain miners to process it with priority.
  When sending cryptocurrency, the network fee determines the priority of your transaction in the queue of pending transactions. Miners/validators will prioritize transactions with higher fees. Choose higher fees if you need fast confirmation or lower fees if you can wait and want to save on costs.

  
  2. Incorrect address. Ensure that the recipient's address matches the address in your Tangem Wallet. An error in the address can make it impossible to recover the funds. Once a cryptocurrency transaction is confirmed and added to the blockchain, it cannot be canceled or reversed. This immutability is a fundamental feature of blockchain technology. The only way to recover the funds is to ask the recipient to send them back if you know who they are.

  
  3. Wrong network. Ensure you have selected the same network in the Tangem Wallet and the platform from which you are transferring. Many tokens operate on multiple networks simultaneously. If the transfer is made through a network different from the one specified when generating the recipient's address, the coins may be lost, and recovery will be impossible.

  If the network used for the transfer is supported by Tangem Wallet, you can recover the funds by adding the token to the main screen. You can add the token through the “Manage tokens” section or manually add the token via its smart contract address.

  
  Here are guides for adding tokens:

  How to add a custom token using a contract address:

  - How to add a token to the correct network
  - How to add a custom token using its contract address

  
  If you sent the transaction to a wallet address on an unsupported network, you won’t be able to manage the coins until support for that network is added.
  
  4. Different contract addresses. Token contract addresses often change, which can cause issues with receiving tokens in your wallet. It is essential to ensure that the contract address of the sent token matches the one in the Tangem Wallet. You can check the token's contract address sent to the blockchain explorer using the transaction ID (txID or hash).
  To find the contract address of a token in the Tangem app, follow these steps:
  1. Open the Tangem app and log in to your wallet.
  2. Tap the three dots in the top right corner.
  3. Select the relevant wallet.
  4. Go to the Manage tokens section.
  5. Use the search bar to find the token you need.
  6. Tap and hold the name of the relevant blockchain, and the contract address will be copied to your clipboard.
  7. You can paste it for viewing or use in other apps.

  
  If you encounter a problem not described here, we recommend contacting Tangem support for further assistance and giving us the transaction’s ID (txID or hash).

• I sent cryptocurrency to the smart contract address. How can I get it back?

  Cryptocurrency transactions can be nerve-wracking due to the potential for mistakes. If you send funds to the wrong address, especially a contract address, it may be difficult or impossible to recover them.

  
  The immutable nature of blockchain transactions
  Blockchain technology's key feature is its immutability. Once a cryptocurrency transaction is confirmed and added to the blockchain, it cannot be reversed. Accidentally sending cryptocurrency to a contract address could result in permanent loss of funds.

  
  Characteristics of the contract address
  A contract address typically lacks a refund feature and can only perform functions specified in its source code. It cannot be controlled like a regular address because it lacks a private key. Under such circumstances, the contract creator may be unable to intervene if funds are sent to the contract address in error.

  
  Consequently, the possibility of returning funds sent to a contract address largely hinges on the contract's design. Contacting the contract creator or team members for assistance or a resolution is advisable.

  
  Here are some recommended steps for addressing the issue:
  
  1. Contact the contract owner: Reach out to the owner or responsible team members of the contract. Explain the situation and inquire about the potential for a refund. Some contracts may enable the owner to return erroneously sent funds, but this is not guaranteed.

  
  2. Seek community solutions: The community associated with a token or project linked to a contract address might offer guidance or assistance based on past similar incidents. Exercise caution with private messages and refrain from trusting individuals proposing to communicate via WhatsApp. While engaging with crypto communities on social media, it's best to communicate in public channels for assistance and transparency.

  
  Due to the irreversible nature of blockchain transactions, there is no assurance of fund recovery. Hence, it's crucial to carefully verify addresses before confirming transactions and conduct a test transfer before sending the complete amount to prevent such issues.

• I sent cryptocurrency to the wallet on an unsupported network, what should I do?

  You cannot manage your tokens if you have sent funds to your wallet address on an unsupported network. However, you still own these tokens since you have private keys for the addresses to which they belong. You can see them in your wallet until we support the specific network.

  
  We continuously update and expand the list of assets we support. We also regularly collect user feedback and conduct research to determine how to add assets to the wallet.

  
  Adding network/blockchain support requires time and careful work, including research, development, testing by the QA team, beta testing, and releasing updates. To stay informed about when we add support for the desired network, follow our updates via social networks.

  
  Until we add support for this network, please do not reset your Tangem wallet to factory settings. This is crucial because resetting it will completely delete all wallet addresses stored on the card.

  
  To view and withdraw the amount sent to your Tangem wallet, you will need the specific address to which you transferred the funds.

  
  If you have set up your wallet with a seed phrase, you can use it in another wallet that supports this network to regain access to your funds.

• How do I sell cryptocurrency? Can I withdraw money from Tangem to my bank card?

  The Tangem app allows you to sell cryptocurrency directly to your bank card through the integrated MoonPay service.
  
  To do this, you need to open the Tangem app and log into the wallet. Then, on the main screen, choose the required cryptocurrency and tap "Sell". After that, you’ll be redirected to the MoonPay service. Detailed step-by-step instructions on how to sell cryptocurrency through MoonPay can be found here.
  
  The terms of selling cryptocurrency (available cryptocurrencies, non-supported countries, fees, minimum sale amount) can be found on the MoonPay website via the link.

• Why are the Swap, Buy, and Sell buttons not available?

  The Tangem app lets you buy, sell, and exchange cryptocurrencies using integrated third-party services such as Mercuryo, MoonPay, 1inch, OKX, ChangeNOW, Changelly, and ChangeHero. If the trade, buy, and sell buttons in your wallet are grayed out, and you cannot select any of these options for a specific token, it means that the token is not supported by the third-party services integrated into Tangem Wallet. To confirm if this is the issue, you can check if the token(s) are supported here:
  • MoonPay
  • Mercuryo
  • Changelly
  • ChangeNow
  • ChangeHero
  
  Please note that the Buy and Sell button availability also depends on the country. A list of unsupported countries can be found here:
  • MoonPay
  • Mercuryo

• What is the difference between "legacy" and "default" addresses?

  There are two types of wallet address: SegWit and Legacy. In the Tangem app, SegWit is displayed as "default", and Legacy as "legacy".
  
  Using a SegWit address reduces fees by 30–40%, and the transaction processing speed is faster than with Legacy. We offer two types of addresses because not all exchanges support SegWit addresses.
  
  You can transfer funds using either of these addresses.

• How long does it take to process a transaction?

  The time it takes to process a transaction is determined by the blockchain network, not the wallet used. Network congestion and the transaction fee set by the sender influence the speed of transaction processing.

  
  When you send cryptocurrency, the network fee you choose affects the priority of your transaction in the queue of pending transactions. Miners and stakers tend to prioritize transactions with higher fees. Select a higher fee for faster confirmation or a lower fee if you can wait to save on costs.

  
  Tangem offers 3 fee levels based on the current network load: Slow, Market, and Fast. Alternatively, you can set your own network fee for your transaction.

  The app calculates the fee based on network load, transaction volume, and execution priority. If you set the fee yourself, ensure it's sufficient for confirmation; a low fee may prevent the transaction from being confirmed.

  You can find more information about network commissions in our blog post: What is a Transaction Fee in Crypto and How is it Calculated?

  
  Here’s how to monitor the transaction in the Tangem app :
