Sending Crypto
How do I send cryptocurrency from a Tangem wallet?
Here are the steps to send cryptocurrency using the Tangem Wallet:
1. Open the Tangem app and log in to your wallet.
2. Сhoose the cryptocurrency you want to send on the homepage and tap Send.
3. Specify the number of tokens or their dollar equivalent. You can also send all the tokens by selecting Max.
4. Enter the recipient’s address or paste it. Double-check the addresses you copy and paste. You can also select one from the list of past recipients.
Please make sure that you are sending the cryptocurrency to the correct network. If the transfer is made to a network other than the recipient's address, the tokens may be lost and cannot be recovered.
5. Enter a Memo if you have one.
6. Under Network fee, you can change the fee level— the default is Market. You can also set your network fee amount by selecting Custom. Ensure that the custom fee size is enough to confirm the transaction.
7. Review all information before tapping Send.
8. Enter your access code or biometric ID and scan your Tangem to sign the transaction.
Once the transaction is successfully signed and sent to the blockchain, the balance will be updated after some time. You can track the transaction status in the application history or through the blockchain browser. To do this, click on the currency on the main screen. Select View Transaction History or Explorer to go to the blockchain explorer.

How does Send via Swap work in Tangem Wallet?
The Send via Swap feature in Tangem Wallet combines two actions into one: exchange and transfer. You can now convert a token into another and immediately send it to the recipient’s address without performing separate operations.
How to use Send via Swap
1. Open the Tangem app and log into your wallet.
2. On the main screen, select the cryptocurrency you want to exchange and send, then tap Send.
3. Enter the amount of tokens or its equivalent in USD. To send your entire balance, tap All.
4. Under the amount field, tap Convert to another token.
5. From the list, select the token you want to convert into and send to the recipient.
6. Select the token’s network.
7. Enter the recipient’s address.
— Always double-check the copied and pasted address.
— Make sure the sender’s and recipient’s networks match. Many tokens exist on multiple networks. If the transfer is made through the wrong network, funds will be lost and cannot be recovered.
8. In the Provider field, you can change the exchange provider.
9. In the Network fee field, you can adjust the fee level to Fast. By default, Market is selected.
10. Review all details, then tap Send.
11. Enter your access code or use biometrics, then scan your Tangem card to sign the transaction.
Example:
You have USDT, but the recipient needs ETH.
1. Select USDT and tap Send.
2. Enter the amount and choose Convert to another token.
3. From the list, select ETH and specify the Ethereum network.
4. Enter the recipient’s address.
5. Tangem will automatically convert USDT into ETH and send ETH directly to the recipient’s wallet. This way, the recipient immediately gets the currency they need, and you don’t have to perform extra steps.
Important: Send via Swap is not available for the following networks: XRP Ledger, Stellar, Cosmos, TON, Terra, Terra Classic, Internet Computer.

How can I send NFTs from my Tangem wallet?
To send NFT from Tangem Wallet, follow these steps:
1. Open the Tangem app and log in to your wallet.
2. On the main screen, select the NFT Collections section.
3. Expand the desired collection and select NFT.
4. Tap Send.
5. In the sending window, specify the recipient's address. Be sure to verify the addresses you copy and paste. 6. You can change the fee level. By default, it is set to "Market". You can also set your fee amount.
Note: If you decide to set the fee amount yourself, make sure it is sufficient to confirm the transaction; sending one with a fee that is too low might prevent it from being confirmed.
7. Check all input data before tapping Send.
8. Scan the Tangem Wallet to sign the transaction.
The transaction has now been successfully signed and sent to the blockchain. You can track its status in the in-app history or by using the blockchain explorer. To do this, select the coin from the home page. To switch to the blockchain explorer, select Explorer or Explore transaction history.
Important: When making a transfer, ensure that the networks of the sender and recipient match. Many tokens operate on multiple networks simultaneously. If the transfer is made on a different network than the one specified by the recipient when generating the address, the NFTs may be lost and cannot be recovered.

Why is the Send button disabled?
If Send is disabled, you likely do not have sufficient 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 example, for BNB Smart Chain tokens (BEP-20), the fee is charged in BNB, whereas 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, rather than in the token you are transferring. For example, if you're transferring BNB Smart Chain tokens (BEP-20), the commission will be deducted in BNB, and if you're dealing with TRON tokens, the commission will be deducted in TRX, and so on. Therefore, you need to have enough of the network's native coin to pay the fee in order to successfully complete a transaction, even if you are transferring other tokens.
What is the fee charged for sending funds?
You only have to pay a network (blockchain) fee for the transfer, which miners or validators receive as compensation for processing the transaction. No additional commission is charged when sending funds from your Tangem Wallet.
The specific commission amount depends on the network used; for instance, the Bitcoin network will have a different fee compared to the Bitcoin Cash, Ethereum, or Litecoin networks.
This fee may fluctuate based on market demand and current network capacity. You can find the fee amount indicated on the Send page. Enter the recipient's address and amount to view the network fee.
What does "Fee exceeds balance" mean?
"Fees exceed balance" means that you do not have enough funds to cover the network fees. It's important to note that the fees are charged in the network's native coin, not in the specific token you are transferring. For instance, when transferring BNB Smart Chain tokens (BEP-20), the fee is charged in BNB, whereas for TRON tokens, the fee is charged in TRX, and so forth.
How do I choose a network fee?
The network fee determines the priority of your transfer in the queue of unconfirmed transactions. Miners prioritize transactions with higher fees to include them in the block first, resulting in faster processing. If speed is not a priority, you can set a lower fee to save money.
Tangem offers three 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 choose to set the fee yourself, make sure it's sufficient for confirmation; a low fee may hinder 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.
How are fees charged on the Arbitrum network?
Arbitrum One (ETH) is the native coin of Ethereum on the Arbitrum network. When you conduct transactions on the Arbitrum network, fees are charged in Arbitrum One (ETH) instead of the specific token being transferred.
To add funds to your Arbitrum One (ETH) wallet, you can buy ETH on 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 serves as its native coin. When you conduct transactions on the Base network, fees are charged in Base (ETH) instead of the specific token you are transferring.
To replenish your Base (ETH) wallet, you can purchase 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) refers to Ethereum on the Optimistic Ethereum network, which is its native coin. When you conduct transactions on the Optimistic Ethereum network, fees are charged in Optimistic Ethereum (ETH) instead of the specific token you are transferring.
To add funds to your Optimistic Ethereum (ETH) wallet, you can buy ETH from an exchange and then transfer the tokens to your wallet on the Optimistic Ethereum network.
How long does it take to process a transaction?
The time required 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 select affects the priority of your transaction in the queue of pending transactions. Miners and stakers tend to prioritize transactions with higher fees. Choose a higher fee for faster confirmation or a lower fee if you can wait to save on costs.
Tangem offers three 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 that it's sufficient for confirmation; a low fee may prevent the transaction from being confirmed.

Here's how to monitor the transaction in the Tangem app:
1. Open the Tangem app.
2. Tap the coin/token you are interested in.
3. Scroll down and tap on the transaction you need. This will take you to your wallet's public address in the explorer.
4. Scroll through the list of transactions until you find the one you want.
I made the wrong transaction. Can I cancel/refund a transaction?
Once a cryptocurrency transaction is confirmed and added to the blockchain, it cannot be canceled or reversed. This immutability is one of the fundamental features of blockchain technology. The only way to reverse a transaction is to ask the recipient to send the funds back if you know who they are.
What should I do if I sent funds to an exchange but forgot to indicate the memo/tag?
If you forget to specify a memo or tag when transferring cryptocurrency to an exchange, contact the exchange support team. They typically have a procedure for these cases.
Provide them with all the necessary details about your transfer, such as the transaction number, transfer amount, and any other information that can help them identify your transaction. The exchange can assist in restoring 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 Explore Transaction History or Explore. This will direct you to your wallet's public address in the explorer.
3. Scroll through the list of transactions until you locate the one you need.
4. Tap on a transaction to view its details.
I received tokens/NFTs that I did not send. How can I see them in my wallet?
If you notice tokens or NFTs in your blockchain explorer that you did not purchase, trade, or expect to receive, they are likely tokens created to generate interest in a project, or they may be scam tokens. Some blockchains allow for the programming of a smart contract to send tokens to a long list of active addresses or to addresses with certain parameters.
This does not necessarily mean that the scammers know your address or personal information. Tokens are often sent out in large numbers, similar to email spam.
It is not advisable to engage with these tokens or attempt to send or exchange them. Any value they appear to hold is likely fake and intended to entice users into the scam.
These tokens cannot harm your wallet merely by being in your wallet. However, if you do interact with them, you may inadvertently give permission to send cryptocurrency from your wallet, initiate a failed transaction with a high gas fee that benefits the scammer, or become a victim of a malicious contract in other ways.
Why do I see a transaction I did not perform in my transaction history?
We strongly recommend ignoring such transactions and not engaging with them, as they are linked to fraud.
On some blockchains, you can start a transaction from an address that isn't yours. If the transaction value is 0, you don't need to sign it with the private key of that address.
This means that when you send a transaction, you may see a similar recipient address (with similar starting and ending parts but different in the middle) in your transaction history.
The scam tries to trick you into copying a recipient address from a blockchain explorer and using it in a second transaction, but you may accidentally copy a similar, fraudulent address.
To better understand this scam and its details, check out the blog post: Why You Should Never Copy Addresses from the Blockchain Explorer.
Does Tangem Wallet support ENS addresses?
Tangem Wallet now supports ENS addresses, allowing you to send cryptocurrencies using a recipient's human-readable name, such as tangem.eth, instead of a lengthy and complex wallet address.
The Ethereum Name Service (ENS) is a decentralized domain system for the Ethereum blockchain. It transforms standard wallet addresses, like 0xAB...1234, into more user-friendly and memorable names, such as tangem.eth.
How to use ENS addresses in the Tangem wallet?
In the Send window, type the ENS address instead of the usual wallet address. If the ENS name resolves correctly — meaning the Ethereum address linked to the entered name is identified — you’ll be able to proceed with the transaction as usual.
If you see the error "Invalid address", it means the name you entered isn't registered with the ENS system and doesn't match any Ethereum address. Carefully check the spelling and make sure you're using the Ethereum network. Keep in mind that ENS addresses won't work on other blockchains.
If your Tangem Wallet is linked to an ENS address, tapping the Receive button will display both your standard Ethereum address and the associated ENS name. You can copy either one and share it with the sender, depending on what’s more convenient.
What tokens can be sent to an ENS address?
ENS addresses can receive any tokens on the Ethereum network.
Can ENS addresses be used in other networks? No, the ENS system in Tangem Wallet is exclusive to the Ethereum network, ensuring that ENS names resolve correctly only within this ecosystem.
How do I create an ENS address?
1. Visit the official ENS website: https://ens.domains/.
2. Link your wallet using WalletConnect.
3. Choose a name and verify its availability.
4. Select a registration period (minimum of one year) and pay the required fee.
5. Once registered, assign your wallet address to the newly created ENS name.
My transaction is stuck in processing
When you send cryptocurrency, the network fee determines your priority in the queue of pending transactions. The size of the fee accompanying the transaction affects how long it takes for the transaction to be confirmed on the network. If the fee is too low, the transaction may remain pending for a longer period of time or may not be confirmed at all.
Miners prioritize transactions with high fees. Therefore, choosing high fees results in quicker confirmation, while opting for lower fees means you can save on fees but may have to wait longer for confirmation. The current commissions for Bitcoin can be found on websites like https://mempool.space/.
Tangem provides 3 levels of commissions depending on the current network load: slow, market, and fast. You can also set your own network commission for your transaction. The commission amount offered by the application is calculated based on the network load, transaction volume, and execution priority. It's essential to ensure that the commission size is sufficient to confirm the transaction if you set the commission amount yourself.
You can find more information about the network commission in our blog post: What is a Transaction Fee in Crypto and How is it Calculated.
How can I push a pending transaction through?
What is a nonce?
A nonce is essentially a unique identifier for each transaction associated with a specific address on EVM blockchains like Ethereum, BNB Smart Chain, and Polygon. Each new transaction from this address receives the next sequential number: 0, 1, 2, and so on.
Key Point: The blockchain only processes one transaction with a particular nonce at a time.
Why do pending transactions block the queue?
When a transaction gets stuck, usually due to an insufficient fee, all subsequent transactions with higher nonce numbers (e.g., +1, +2, etc.) remain "pending" and cannot proceed. The blockchain will not accept new transactions until the stuck one is resolved or replaced.
If you've sent multiple transactions but none are being confirmed, check if any of them have a lower nonce than the others. It's the one with the smaller nonce that might be holding up the queue.
How do I find the nonce of a pending transaction?
1. Open the transaction in the blockchain browser.
2. Find the More details or the Advanced section.
3. Find the Nonce field — this is the number.
How can I replace a pending transaction?
To replace a pending transaction, you need to send a new one with the same nonce, but with a higher commission.
To execute the transaction:
1. Launch the Tangem app and sign in to your wallet.
2. On the home screen, choose the cryptocurrency sent in the initial transaction.
3. Tap Send.
4. Enter the recipient's address, which might differ from the original.
5. Specify the amount of tokens or their dollar equivalent, which could also vary.
6. Select Custom in the Network fee option.
7. In the following fields:
— Enter the nonce of the suspended transaction, retrievable from a blockchain explorer.
— Set the commission higher than that of the initial transaction with the same nonce.
We advise using the recommended fees under Market and Fast.
8. Review all details and confirm by tapping Send.
9. Scan your Tangem Wallet to sign the transaction. If everything is correctly set, the new transaction will replace the old one and be confirmed on the network.
Which networks support transaction replacement?
This feature is available on all EVM networks, including ApeChain, Arbitrum, Areon, Aurora, Avalanche C-Chain, Base, Bitrock, Blast, BNB Smart Chain, Canxium, Chiliz EVM, Cronos, Cyber, Dione, Ethereum, Ethereum Classic, Ethereum PoW, Fantom Opera, Flare, Gnosis, Kava EVM, Manta Pacific, Mantle, Moonbeam, Moonriver, Optimistic Ethereum, Polygon, Polygon zkEVM, PulseChain, RSK, Shibarium, Sonic, Telos, and zkSync Era.
What happens if I don't specify the nonce manually?
If you send a new transaction without manually setting the nonce, it won't replace the suspended one. The transaction will receive the next available number and wait until the previous one is confirmed. Both transactions will incur a fee.
I have multiple pending transactions. What should I do?
If you have several pending transactions, start with the first one (the one with the smallest nonce) and replace it step by step until you unlock the entire queue.
Important: When replacing the first suspended transaction (the one with the lowest nonce), the blockchain can automatically process subsequent transactions if they have a sufficient network commission. This is handy if you want to send all your transactions simultaneously, but it also carries a risk if you intend to execute only one.
