Before withdrawing assets from Huobi to imToken, you need to know <a href="https://support.token.im/hc/en-us/articles/115001657313-Which-chains-and-tokens-does-imToken-support-">what digital currencies are supported by imToken</a>. You can not receive the transferred tokens from the exchange if they are not supported by imToken.
<h2>How to Withdraw Assets from Huobi Global to imToken?</h2>
<h3>1. Choose the Token You Want to Withdraw</h3>
Open the Huobi Global App and click “Assets” - “Withdraw” to choose the token you want to withdraw.
 <img src="https://support.token.im/hc/article_attachments/7086416839833/_1.png" alt="_1.png">
<h3>2. Check Whether the Token Is Supported by imToken or Not</h3>
Check whether imToken supports the token or not according to its “Withdrawal Network” shown in the exchange. For instance, USDT can be withdrawn through ERC20, TRC20, HECO, BEP20, OMNI, ALGO, SOL, and AVAXCCHAIN (Avalanche C-Chain). However, ALGO and SOL networks are not supported by imToken.

<h3>3. Choose the Withdrawal Network</h3>
You can withdraw USDT from Huobi to imToken through ERC20, TRC20, HECO, BEP20, OMNI, and AVAXCCHAIN. 
<ul>
<li style="font-weight: 400;" aria-level="1">ERC-20 is a token standard on Ethereum. ERC20 tokens can be managed by ETH wallets. Its withdrawal is fast but the fees are relatively high. </li>
<li style="font-weight: 400;" aria-level="1">TRC20 is a token standard on TRON. TRC20 tokens can be managed by TRX wallets. Its withdrawal is fast and the fees are low. </li>

<li style="font-weight: 400;" aria-level="1">At least 0.001 AVAX in your Avalanche wallet.</li>
<li style="font-weight: 400;" aria-level="1">At least 0.0001 HT in your HECO wallet.</li>
</ul>
Note: gas fee is charged by the blockchain network, not imToken.
<h3>4. Copy the Wallet Address</h3>
Open imToken and click the menu button at the top left corner to select the wallet that you want to transfer to. For instance, you should choose the ETH wallet if you want to withdraw USDT to it. In your ETH wallet, click “Receive” - “Copy” to copy the wallet address.
<img src="https://support.token.im/hc/article_attachments/7086477497753/__3.png" alt="__3.png">
<h3>5. Enter the Copied Address in Huobi Global</h3>
In the Huobi Global App, paste the copied ETH wallet address on the withdraw page, select ERC20 and enter the amount. Then click “withdraw” and complete verification for the withdrawal. After the exchange shows “withdrawal successful”, you can see the transferred tokens in imToken.

<h2>FAQ</h2>
<h3>1. Why are the transferred tokens not shown in imToken?</h3>
There are three common reasons:
Reason 1: the tokens haven’t been sent by the exchange.
In this case, please reach out to customer service of the exchange.
Reason 2: the transferred tokens are not supported by imToken.
Check whether you have transferred unsupported tokens according to this blog <a href="https://support.token.im/hc/en-us/articles/115001657313-Which-chains-and-tokens-does-imToken-support-">Which chains and tokens does imToken support?</a>. If so, please reach out to the project team of that token to help you retrieve your funds.
Reason 3: you chose HECO when withdrawing
The tokens have been transferred to your HECO wallet in imToken if you selected HECO network when withdrawing. You can see the token by following the steps below:
<ul>
<li style="font-weight: 400;" aria-level="1">Open the ETH wallet, click "Ethereum"at the top, and click "Huobi ECO Chain" to switch to the HECO wallet.</li>
<li style="font-weight: 400;" aria-level="1">Click "+" - "Custom Token" on the wallet page, fill in the contract address of the token, and click "Save" after Symbol and Decimal are automatically filled.</li>
<li style="font-weight: 400;" aria-level="1">Return to the wallet page, and you can see your assets.</li>
</ul>
<h3>2. Why Should I Backup the Mnemonic When Using imToken?</h3>
As a self-custodial wallet, imToken does not store users’ mnemonics. In other words, it cannot be retrieved once users lose their mnemonics. Given that, to better protect your assets, please carefully backup your mnemonic.

<h3>3. Why Does My EOS Wallet Show “Pending Creation”?</h3>
EOS utilizes an account system with a resource staking mode. So you have to pay to complete the EOS account creation process.

How to withdraw assets from Huobi to imToken?

You’ll get the error if the wallet address you entered into the exchange does not match the withdrawal method you selected.
Before sending tokens from  the exchange to imToken, you need to know if imToken supports the token. If you transfer a token that is not supported by imToken, the exchange will show a successful withdrawal, but the assets in your wallet will not be credited.
We list the wallets supported by imToken and the corresponding withdrawal networks in the table below

Error “Invalid address” when sending tokens from exchange to wallet

Please choose the corresponding solution according to the error you got.
<h3 class="wysiwyg-text-align-justify">Error “invalid mnemonic”</h3>
This happens because some of the words in your mnemonic aren’t in the <a href="https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt" target="_self">BIP39</a> wordlist. You should find out the right words according to the wordlist.
<h3 class="wysiwyg-text-align-justify">Error “Incorrect length of Mnemonic Phrase”</h3>
This happens because the length of the mnemonic you imported is not 12/18/24 words. You need to check if you missed a word or entered an extra word
<h3 class="wysiwyg-text-align-justify">Error “incorrect mnemonic checksum”</h3>
To solve this error, we should understand what checksum is first. A checksum is the 12th word in your mnemonic, which is generated according to the first 11 words. It can also be used to verify the first 11 words. You may encounter this error under the following scenarios:
<ol class="wysiwyg-text-align-justify">
<li>You changed the word order.</li>
<li>One of these words isn’t in the <a href="https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt" target="_self">BIP39</a> wordlist.</li>
</ol>
Both of these cases are caused by a wrong backup of your mnemonic, so we suggest you to find the correct one.

Error “invalid”or “incorrect length” when importing mnemonic

Please check it according to the followings:

What if the transfer is successful but the other party did not receive it?

Token prices in imToken are provided by information data platforms such as CoinGecko and CoinMarketCap. If the fiat value of your token is not showing in imToken, it means that the token is not yet listed on these platforms. 
However, it won’t impact your ability to manage your assets. You can still start a transaction as normal.

Why is the fiat value of my token not showing?

The password is at least 8 characters long, you can keep trying your common password combinations to retrieve it, and there is no limit for invalid attempts. If you are still unable to retrieve your password, please follow the tutorial below to reset it.
Note: imToken is a self-custodial wallet and doesn’t store users’ information. So if you forget or lose your password, imToken cannot help you to retrieve it. 
<h3>How to reset password?</h3>
Prerequisite: You have backed up the mnemonic/private key correctly, otherwise it’s impossible to reset the password.
There are two types of wallets in imToken: Identity wallet and Create/Import wallet. Please find the corresponding tutorial for the wallet you want to reset the password for.
PS: If you are not sure whether your wallet is an Identity wallet or a Create/Import wallet, please check it by clicking "My Profile" - "Manage Your Wallet".

Keywords: "Forgot Password", "Reset Password", "Change Password"

What should I do if I forget my password?

If tokens are sent out of the wallet without your consent, it means that your assets have been stolen. Please remain calm and follow the steps below to respond.
<h2>Step 1: Transfer the remaining assets in your wallet</h2>
imToken is a self-custodial wallet, and unlike banks, it cannot freeze your wallet account or that of the person who stole your funds. So when you discover that assets have been stolen, check if there are any tokens left in all your wallets on imToken. If so, transfer the remaining assets to a secure wallet address or exchange account ASAP.
<h2>Step 2: Examine the cause and gather clues</h2>
There are two main causes of asset theft.
<ul>
<li>Compromised mnemonic, private key or keystore.</li>
<li>Unconsciously grant scammers the transfer authorization, which allows them to transfer your assets.</li>
</ul>
Please note that in the above two cases, the thieves can transfer your assets without knowing your wallet password.
<h3>Cause #1: Compromised mnemonic, private key or keystore</h3>
When you create a wallet with imToken, you will see the reminder “Obtaining Mnemonic equals owning all assets”. This means that if your mnemonic is compromised, someone else can transfer your assets without knowing your wallet password.
<img src="https://support.token.im/hc/article_attachments/6898386315801/image4.png" alt="image4.png">
Common causes of compromise:
<ul>
<li>Download a fake imToken App from a fake website or unofficial channel.</li>
<li>Copy of the mnemonic was seen by someone close to you.</li>
<li>Take a screenshot/photo of the mnemonic and save it in your phone album.</li>
<li>Save the mnemonic in WeChat, memo, mailbox, computer folder, notebook or USB stick.</li>
<li>Send the mnemonic by email or instant message tools.</li>
<li>Enter the mnemonic into third-party websites or other wallets.</li>
<li>Import the mnemonic generated by a third-party risk wallet into imToken.</li>
<li>Import the mnemonic generated by imToken into a third-party risk wallet.</li>
<li>Copy and paste the mnemonic, etc.</li>
</ul>
Why can someone transfer your assets without knowing your wallet password?
imToken is a self-custodial wallet that can be used to manage mnemonics, private keys and keystores, but does not store your assets. Your assets are stored on the blockchain, not within imToken, and the amount of assets you see in your wallet is the data that imToken pulls from the blockchain.
The mnemonic represents the ownership of the asset you own on the blockchain. Once someone else has access to your mnemonic, they can log into your wallet on another device and set a different password to steal your assets. Blockchain allows users to have full control over their assets, however, this also means that they are solely responsible for their assets.
<h3>Cause #2: Unconsciously grant scammers the transfer authorization</h3>
Scammers often trick users to access third-party websites through the imToken browser to obtain the transfer authorization, which allows them to transfer your assets without your permission.
To help users to stay alert, the latest version of imToken has optimized the risk warning when users grant transfer authorization.
<img src="https://support.token.im/hc/article_attachments/6898385799705/image1.png" alt="image1.png">
If you give authorization to a malicious third party, you are actually granting the scammer permission to transfer your assets, and he can steal your assets without knowing your mnemonic and password.
The common ways for scammers to obtain authorization are: scam token airdrop, fake liquidity mining and QR code payment.
Scam token airdrop
Scammers airdrop tokens to your address, and the token information contains false content to lure you to access a third-party website for exchange, thus fraudulently obtaining transfer authorization.
Fake liquidity mining
Scammers impersonate imToken officials on channels such as Telegram, WhatsApp, Youtube etc. and offer you a very good investment opportunity: Deposit USDTs into imToken and participate in liquidity mining or staking to get guaranteed daily earnings, the more tokens you deposit, the higher the rate of return.
When you confirm a transaction on the scam website to start the so-called liquidity mining or staking, you are actually giving the transfer authorization to the scammer.
Note: The DApp browser in imToken is an open portal that allows you to open a third-party website from imToken. It does not mean that imToken has a partnership with these projects.
<h2>QR code payment</h2>
Scammers lure you to scan a QR code or click a link, which opens a scam website mimicking the transfer page of your wallet App. The site takes you through an imitation of the familiar transfer interface and obtains your transfer authorization.
If you want to check the authorization status of your wallet, please refer to this blog <a href="https://support.token.im/hc/en-us/articles/900006746566-" target="_self">My USDT was sent out from my wallet without my consent. How did that happen?</a>
<h2>Step 3: File a police report</h2>
Go to your local police station to file a report. Transactions cannot be reversed or frozen on blockchain, so the only way to retrieve your money is to file a police report and ask them to find out the scammer. If the police have any questions, please contact us by sending an email to hack@token.im.
<h2>Q&amp;A</h2>
<h3>How to check whether the imToken App downloaded is fake or not?</h3>
If you haven't uninstalled imToken on your phone, you can check it by comparing the SHA256 of the imToken APK file with the string stated on our official website. If they are the same, it means you downloaded a genuine imToken.

What should I do if my assets are stolen?

Common Questions

First of all, please confirm the following:
<ol class="wysiwyg-text-align-justify">
<li style="font-weight: 400;">The phone network is normal</li>
<li style="font-weight: 400;">Already switched to the corresponding wallet address</li>
</ol>
Then, click the "+" button on the assets page of the app and select "All my assets" to add the token manually.
Additionally, if you have more types of tokens, you can find them by searching.
Keywords: "received notification", "assets doesn’t display"

What if I received a transaction notification but the token does not display?

If you find that the asset is missing, please check if the address of your imported wallet is the same as your original wallet address.
If it does, you need to <a href="https://support.token.im/hc/en-us/articles/360004344834">add the token to the assets list</a>.
If it does not match, it means that you have imported the wrong token/private key. There are mainly three scenarios:
<ol>
<li class="wysiwyg-text-align-justify" style="font-weight: 400;" aria-level="1">You have more than one mnemonic/private key, the imported one is not the wallet you want to restore. You can fix it by finding the correct one and re-import it.</li>
<li class="wysiwyg-text-align-justify" style="font-weight: 400;" aria-level="1">The mnemonic/private key you backed up is wrong or you made a typo when entering the mnemonic/private key. </li>
</ol>

Imported or restored wallet, but the assets are missing?

Please click "Resend" to resend the transaction. If you have multiple transactions showing "Unsubmit", please resend them one by one, starting with the earliest one.

What should I do if the transfer shows "Unsubmit"?

Here are some common reasons for the failure:
<ul>
<li style="font-weight: 400;" aria-level="1">Out of Gas</li>
<li style="font-weight: 400;" aria-level="1">Bad Instruction</li>
<li style="font-weight: 400;" aria-level="1">Reverted</li>
</ul>
Click "Query Details" on the transaction detail page to check why the transaction failed and try to resolve the issue based on the specific reason:.
<h2>Out of Gas</h2>
The transfer failed due to insufficient GAS, please set a higher Gas according to the <a href="https://support.token.im/hc/en-us/articles/4411976294553">EIP-1559 Miner Fee Setup Tutorial</a>. 
<h2>Bad Instruction or Reverted</h2>
The transfer failed due to a problem with the smart contract of the token. You should reach out to the developer of the smart contract.
Note
<ul>
<li style="font-weight: 400;" aria-level="1">The miner fees are charged by the Ethereum network rather than imToken.</li>
<li style="font-weight: 400;" aria-level="1">Even if the transaction fails, the miner fees you paid to Ethereum network will not be refunded.</li>
</ul>

What should I do if my transaction fails?

ETH wallet transfers require ETH to pay for the transaction fee. If you encounter this error when transferring funds, please deposit some ETH to your wallet to pay for the transaction fee.
Note: It is recommended to have at least about 0.02 ETH in your wallet. The transaction fee is charged by the Ethereum network rather than imToken.

Error “Insufficient ETH for transaction fee” when transferring

The cause of an “UNSUBMIT” transaction, might be one of two:
<ol class="wysiwyg-text-align-justify">

After the transaction is successful, the status will update to “Pending”

Transaction Unsubmit

The cause of a "replaced transaction" is the following:
You sent one transaction with a low gas price before sending a follow-up transaction (with the same nonce) with a higher gas price (i.e. miners’ fee). The miners picked up the transaction with higher miners' fees, so the transaction with lower miners' fees was replaced. (The Nonce values ​​for the two transactions are the same.)
You can click on "Go to Etherscan for more details" to see all the transactions in and out of your wallet and decide whether to re-initiate a new transfer based on your needs.

Transaction Dropped & Replaced

Transactions on blockchains are irreversible, so the only way to get back your tokens is to ask the owner of the address to send them back.
<ul>
<li class="wysiwyg-text-align-justify">You can reach out to the customer service to get back your assets if the address is owned by a platform.</li>
<li class="wysiwyg-text-align-justify">You can ask your friend to turn back your assets if the address belongs to him.</li>
<li class="wysiwyg-text-align-justify">You can try to contact the project team to ask whether it is possible to retrieve your assets if the address is owned by a smart contract.</li>

imToken is a multi-chain wallet and supports all the token in corresponding chains. Users can add new tokens to their asset list using the search feature. Please <a href="https://support.token.im/hc/en-us/articles/360004344834" target="_self">click here</a> to learn how to search for a token and add it.
With the rapid development of public chain ecosystem, there are more than thousands of tokens on different chains. In order to make it easier for users to manage their tokens, we will choose some popular tokens in community and add it to the imToken token list for users to search. So you can’t find a token when imToken didn’t add it. But if you can’t find it in imToken, it doesn’t mean imToken doesn’t support the token. As long as the token meets the token standard of the chain (click <a href="https://support.token.im/hc/en-us/articles/115001657313" target="_self">here</a> to know more about the standards), you could manage the token in imToken.
<h3 class="wysiwyg-text-align-justify">Attention:</h3>
All tokens in the imToken token list are only for the convenience of user management and adding tokens. It doesn’t mean these tokens are backed or reviewed by imToken. Please do not use this as a basis for judging the quality of tokens.

Why can’t I find a token when searching its name?

Generally speaking, the reason why your imToken wallet can’t receive assets is the sender (exchange / individual) didn’t send you the token, so please confirm with the sender in time. 
Note: Some exchanges tips the token to be sent successful, when they actually are not.
<h3 class="wysiwyg-text-align-justify">How to confirm whether the sender has sent the token?</h3>
Method 1: (Simple)
Click the "+" button on the assets page of the app and select "All my assets". If you do not see the token, or the amount of the token is incorrect, it means that the token has not been transferred to your wallet. You should contact the sender to transfer the token as soon as possible.
Method 2: (Professional)
<ol class="wysiwyg-text-align-justify">
<li style="font-weight: 400;">Open the Etherscan DApp from Browser page on the App</li>
<li style="font-weight: 400;">Check if there is a new transfer to your address</li>
<li style="font-weight: 400;">If there is no transfer record, means the token has not been transferred to your wallet.</li>
</ol>
<h3 class="wysiwyg-text-align-justify">If I send the coin to imToken but it is unsupported, what should I do?</h3>
imToken cannot manage unsupported tokens. If this happens, please contact the project technician to solve it.
Keywords: "can’t receive coins", "back my assets"

What if imToken can't receive my assets?

Recently, there have been fraudulent incidents caused by malicious tokens with duplicate names. Therefore, imToken 2.0 will add "_UNKNOWN" to the token name for tokens with the same name that have not submitted a Token Profile to help users better distinguish tokens with the same name.
<h3>For imToken users</h3>
If you receive a token marked "_UNKNOWN", please judge carefully to avoid being cheated.
Example: Above is the official HT token of the Huobi exchange. Below are tokens with the same name.
<img src="https://support.token.im/hc/article_attachments/360044813893/_____20190814114847.jpg" alt="_____20190814114847.jpg" width="545" height="228">
<h3>For token project parties</h3>
If the token issued by the project party is marked with "_UNKNOWN" by default, it indicates that the token has the same name as an existing token. If you need to remove this mark, you can submit Token Profile to imToken, and after passing, you can remove the "_UNKNOWN" mark.
How to submit token information yourself:
<a href="https://github.com/consenlabs/token-profile/blob/master/README.md">https://github.com/consenlabs/token-profile/blob/master/README.md</a>

Why are some tokens marked as _UNKNOWN?

imToken cannot receive unsupported tokens. Before you use imToken to receive tokens, make sure imToken does support it. If the unsupported tokens are transferred to imToken, you need to contact the technical staff of the token project party to help you to get the token back.
<h3>Attentions:</h3>
<ol>
<li style="font-weight: 400;" aria-level="1">If you send ETC to imToken ETH wallet by mistake, you could export the mnemonic / private key of ETH wallet and import it into a wallet which supports ETC to retrieve your token.</li>
<li style="font-weight: 400;">The format of address of VNT、SMT、CMT、GO and some other tokens is the same as that of an ETH address, but they are different mainnet tokens. So if you send these tokens to an ETH address, according to the project official instructions, you can download the official wallet and then import the ETH wallet’s mnemonic into the official wallet to get the token back. </li>
</ol>

What should I do if I sent a token that is not supported by imToken?

ETH Wallet

You can activate your TRX wallet by depositing TRX into the wallet. 
If you want to make transactions after the activation, please make sure there is enough available TRX in your wallet to provide bandwidth and energy. Otherwise the transfer will fail or you will get the error “Not enough TRX or bandwidth for transfer”.
Therefore, it is recommended to deposit 50~100 TRX to your wallet, then you can successfully make transactions after your TRX wallet is activated.
Learn more: <a href="https://support.token.im/hc/en-us/articles/900000089886-TRON-TRX-Wallet">TRON (TRX) Wallet</a>

How to activate your TRX wallet?

TRX wallet does not support the function to add/hide tokens manually. After a token is successfully sent to TRX wallet, it will be automatically displayed on the asset page.
If you want to transfer USDT, NFT, BTT, etc. tokens to TRX Wallet, you can use the TRX wallet address as the receiving address. TRX wallet can be used to receive TRX, TRC10 and TRC20 type tokens.

Why can't I add or hide tokens on the asset page of TRX Wallet?

When transferring tokens such as USDT using the TRX wallet, it consumes <a href="https://support.token.im/hc/en-us/articles/900000089886-TRON-TRX-Wallet">bandwidth and energy</a>. If there are not enough available TRX in your wallet to provide bandwidth and energy, the transfer will fail or you will get the error “Not enough TRX or bandwidth for transfer”.

The <a href="https://support.token.im/hc/en-us/articles/4404302141721-What-is-TRON-Bandwidth-and-Energy-" target="_blank" rel="noopener">bandwidth</a> represents the number of bytes of the transaction size. For example, if the transfer transaction size is 250 bytes, it will consume 250 bandwidth. 2. <a href="https://support.token.im/hc/en-us/articles/4404302141721-What-is-TRON-Bandwidth-and-Energy-" target="_blank" rel="noopener">Energy</a> represents the resource required to execute a specific operation on TRON. For example, if a smart contact transaction consumes 100 μs energy, it means that the transaction requires 100 μs computing resources to execute on the network.
<h2 class="wysiwyg-text-align-left">How to get bandwidth and energy?</h2>
There are two methods to obtain bandwidth and energy
Method 1: Burn TRX (recommended)
Transfer 50-100 TRX into your TRX wallet and when making transactions, a small amount of TRX will be burned to provide the bandwidth and energy required for the transaction.
Method 2: Freeze TRX
Click “Resource” on the asset page to enter the TRON Resource page. Select the type of resource you want to obtain, and enter the number of TRXs you want to freeze. It is recommended to freeze 2000～3000 TRXs. (You can unfreeze and redeem your frozen TRX after 3 days.)

How to get bandwidth and energy?

Each activated account gets 1500 free bandwidth points every 24 hours. So if your bandwidth remains zero, please deposit some TRX to your account to activate it.
If you want to make transactions after the activation, please make sure there is enough available TRX in your wallet to provide bandwidth and energy. Otherwise the transfer will fail or you will get the error “Not enough TRX or bandwidth for transfer”.
Therefore, it is recommended to transfer 50 to 100 TRX to your wallet, then you can successfully make transactions after your TRX wallet is activated.

Why does my bandwidth remain zero?

Each transfer consumes resources, and if you want to make multiple transfers for free, please freeze at least 2,000 to 3,000 TRXs to get enough resources.
The resources obtained by freezing TRXs will take 24 hours to recover after they are consumed. If the energy and bandwidth are consumed to a very small amount, it will not be able to support the resources needed for the transfer and the transfer will fail.
How to fix it?
Transfer 50 ~ 100 TRX to your wallet and don’t freeze them. Then you can successfully make transactions

Transaction still failed after freezing TRX

Tokens will not be deducted if your transfer fails, only a small amount of TRX will be consumed as the transaction fee.
You can check and verify all transactions by entering the wallet address in the blockchain explorer: <a href="https://tronscan.org/#/">https://tronscan.org/#/</a>

USDT transfer failed but no coins returned

Airdrops of scam tokens are rampant on the TRON (TRX) chain. Scammers use the blockchain explorer to find recently active addresses, such as those that have just received or transferred money, and drop scam tokens to them.
Scammers usually attach some fraudulent information to those scam tokens and lure you to access a third-party malicious website to commit fraud.
Therefore, when you find airdrops of scam tokens in your wallet, please just ignore them.

Why would I receive airdrops of scam tokens in TRX wallet?

The error “Account does not exist” indicates that your TRX account has not been activated. You can activate your TRX wallet by depositing TRX into the wallet.
If you want to make transactions after the activation, please make sure there is enough available TRX in your wallet to provide bandwidth and energy. Otherwise the transfer will fail or you will get the error “Not enough TRX or bandwidth for transfer”.
Therefore, it is recommended to transfer 50~100 TRX to your wallet, then you can successfully make transactions after your TRX wallet is activated.

Error “Account does not exist” when freezing tokens

This is because the recipient has never transferred TRX to his address, so the address is not activated. Please do not worry, as inactive wallet addresses can be used to receive tokens normally.
Note: Transferring to inactive addresses will cost you an additional 1.1 TRX, so please reserve at least 1.1 TRX in your TRX wallet when transferring the full amount, otherwise the transfer will fail.

If you still have problems, please contact us by clicking "Support and Feedback" in the App.

What should I do if my Filecoin (FIL) transfer fails?

If the miner fee is set too low, the transaction will show "Pending". You can continue to wait or follow the steps below to accelerate the transaction.

What should I do if my Filecoin (FIL) transfer shows "Pending"?

Memo is a transaction identifier assigned by the exchange to each user. Exchanges only use one or a few addresses to receive ATOM deposits from multiple users, so they need to use the memo to identify the depositor. Therefore, when you send ATOM to an exchange, you have to fill in the memo.
However, the memo is not required when transferring ATOM from an exchange to imToken since imToken is a self-custodial wallet and each user has their own Cosmos (ATOM) wallet address.

What’s the memo when transferring ATOM from an exchange to imToken?

The Cosmos Vega upgrade went live on block 8,695,000, which was at 22:57, Dec.14th, 2021(SGT). So features such as ATOM transfer and staking are not available for users of imToken 2.9.9 and below.
How to fix this?
Please upgrade to the latest version of imToken and then you can use the ATOM transfer and other functions as usual.
To update, simply update via Google Play or Apple App Store

</ol>
Note:
<ul>
<li>Please make sure you have enough ETH in your ETH wallet to pay the miner fee.</li>
<li>If you want to exchange your BTC for USDT in other wallets, please transfer your assets to the exchange for USDT first, and then withdraw USDT to the corresponding wallet in imToken.</li>
</ul>

How to convert BTC in my BTC wallet to USDT?

Open your BTC wallet, click “WrapBTC” and choose imBTC or WBTC. If you have redeemable BTC in your wallet, you will see a redemption button. Click the button and follow the instructions to redeem your BTC.
If you still have questions, please contact the Tokenlon team at support@tokenlon.im for more help.

How to redeem BTC with imBTC or WBTC?

The balance of BTC you see on block explorer is the amount of tokens in a single address, while the balance shown in the BTC wallet within imToken is the sum of all BTC in main address, child addresses and change address, so the balance is different.

Why does the balance of my BTC wallet and the balance on the block explorer not match?

When transferring Omni-USDT to a BTC wallet, please use the main address to receive the money. If USDT is transferred to a child address, it will not show in your wallet. So please do not use child addresses to receive USDT.
If you have already deposited USDT into a child address, you can click "My Profile" - "Manage your wallet" - "Add Wallet" - "BTC" - "Private Key", then import the private key to generate a new BTC wallet to see the USDT received.

Can I receive Omni-USDT using BTC child address?

You can transfer funds between a legacy address beginning with 1 and a SegWit address beginning with 3 in imToken, but not to a native SegWit address beginning with bc1, which is as yet not supported by imToken.
If you want to transfer BTC to a native SegWit address, please first fund your assets to an exchange and then transfer them from the exchange to the address beginning with bc1.

Can I transfer BTC between legacy address, SegWit address and native SegWit addresses?

By default, BTC wallet uses the main address to receive assets. If you want to deposit assets to a BTC child address, please follow the steps below.
<ol>
<li class="wysiwyg-text-align-left">Open your BTC wallet, click "..." in the top right corner</li>
<li class="wysiwyg-text-align-left">Click "Advanced" - "Wallet Address" - select a child address</li>
<li class="wysiwyg-text-align-left">Return to the BTC wallet page, click "Receive" to enter the receive page</li>
<li class="wysiwyg-text-align-left">Click "..." in the lower right corner, click "Child Address" to complete the switch.</li>
</ol>
Note: The setting of child address will only take effect once, after you exit the receive page and re-enter, imToken will still use the main address for receiving by default.

Omni USDT is issued on the Bitcoin blockchain, and each Omni USDT transaction is accompanied by a transfer of 0.00000546 BTC to confirm identity and prevent dust attacks.

Error “BTC balance is insufficient” when transferring USDT

If you set a low miner fee when transferring BTC, the transfer will be pending for a long time.
You can either wait patiently for the miner fees on the BTC network to decrease and your transaction to be packaged by miners, or contact miners to help you accelerate the transfer.
Here’s how to accelerate the transfer
<ol>
<li>Open BTC.com Transaction Accelerator: <a href="https://pushtx.btc.com">https://pushtx.btc.com</a></li>
<li>Enter the transaction hash, then click "ESTIMATE PRICE" and complete the payment.</li>
</ol>

Why is the BTC transaction "pending"?

1. Open the BTC wallet and click “...” at the top right corner on the wallet page - “Advanced” - “Wallet Address”. 2. Swipe left on the child address that you want to export the private key and enter the password. 3. Back up the private key according to the security prompts and keep it safe.

imToken supports two formats of BCH addresses
<ul class="wysiwyg-text-align-justify">
<li>CashAddr: starts with “bitcoincash”</li>
<li>Legacy: starts with “1”</li>
</ul>
Since some exchanges do not support the CashAddr type address, you will get the error “Invalid Wallet Address” when withdrawing BCH from the exchange to your imToken wallet.
But don’t worry, you can fix this by switching addresses within your imToken wallet. The steps are as follows.
<ol class="wysiwyg-text-align-justify">
<li>Open the BCH wallet and click on the address starting with “bitcoincash”</li>
<li>Click "Legacy" to switch to the address starting with “1”</li>
<li>Enter the address into the exchange to withdraw BCH</li>
<li>Done!</li>
</ol>
Note:The imToken BCH wallet asset page displays CashAddr type addresses by default. Since assets in CashAddr and Legacy BCH wallet addresses are interoperable, receipts you make using Legacy type addresses will also be displayed normally in the asset page.

Error “Invalid Wallet Address” when withdrawing BCH from exchange to wallet

Bitcoin (BTC) and Bitcoin Cash (BCH) are two entirely different blockchains. If you accidently sent BCH to a BTC address starting with “3”, you can contact <a href="https://btc.com/" target="_self" rel="undefined">BTC.com</a> to retrieve your assets.

What should I do if I sent BCH to a BTC address starting with “3”

BCH address has three different formats, imToken supports the CashAddr format. Different wallets and exchanges are supporting different address format. Therefore, please make sure to use the correct address when transferring and receiving coins to avoid asset loss.
<h3>Use imToken to send out BCH</h3>

<h4>Note</h4>
<ul>
<li style="font-weight: 400;">Don’t transfer BCH into BTC wallet address, also do not transfer BTC into BCH wallet address</li>
<li style="font-weight: 400;">Different kind of BCH wallet address are derived from the same private key. You cannot transfer them to each other</li>
<li style="font-weight: 400;">The address format from BCH transaction records in imToken is CashAddr format. For example, you set the Legacy address  1QHHy8EdWSN72Uw5GivUK95U7RGSQMoX35 as recipient address, which will be automatically converted to CashAddr, like bitcoincash: qrl4ldj6p27d602z7y806qs2wz4jdxv3eyq9jgv4gm</li>
</ul>

How to use BCH wallet transfer and receive tokens?

imToken currently supports two LTC address formats.
<ul>
<li style="font-weight: 400;" aria-level="1">P2PKH: starts with “L”</li>
<li style="font-weight: 400;" aria-level="1">P2SH-P2WPKH: starts with “M”</li>
</ul>
However, the following are not supported at this time
<ul>
<li style="font-weight: 400;" aria-level="1">Bech 32 type: starts with “ltc”</li>
<li style="font-weight: 400;" aria-level="1">Old address format: starts with “3”</li>
</ul>
So you’ll get the error "Incorrect address" when transferring LTC to an address starting with “ltc” or “3”.
How do I fix this?
Take the address starting with “3” as an example, you can fix this by the following methods.
Method 1: Export the LTC wallet mnemonic, import it into other wallets that support LTC addresses starting with 3.
Method 2: Transfer LTC to an exchange that supports addresses starting with 3, L or M, such as Binance.

In the Polkadot and Kusama networks, users can pay an additional fee to increase the priority of this transaction and make the transaction successful quickly. This additional fee is the "tip".
<h3>Fee Calculation</h3>
Fees on the Polkadot Relay Chain are calculated based on three parameters:
<ul>
<li style="font-weight: 400;">A per-byte fee (also known as the "length fee")：The length fee is the product of a constant per-byte fee and the size of the transaction in bytes.</li>
<li style="font-weight: 400;">A weight fee：Weights are a fixed number designed to manage the time is takes to validate a block. Each transaction has a base weight that accounts for the overhead of inclusion (e.g. signature verification) as well as a dispatch weight that accounts for the time to execute the transaction. The total weight is multiplied by a per-weight fee to calculate the transaction's weight fee.</li>
<li style="font-weight: 400;">A tip (optional)：Tips are an optional transaction fee that users can add to give a transaction higher priority.</li>
</ul>
Together, these three fees constitute the inclusion fee. This fee is deducted from the sender's account prior to transaction execution. A portion of the fee will go to the block producer and the remainder will go to the Treasury. At Polkadot's genesis, this is set to 20% and 80%, respectively.

You need to have some available KSMs in your wallet to pay the transaction fee in addition to the bound KSMs, otherwise you will get the error “Invalid Transaction: Inability to pay some fees”.
Please transfer about 0.01 KSM to your wallet, then you can unbind KSM successfully.
Note: There is a 7-day waiting period for the unbound KSMs, after which you can get back your KSMs.

Due to the unique Cell model of CKB, you need to pay attention to the following when transfer:
<ul>
<li style="font-weight: 400;">Minimum amount of each transfer is 61 CKB</li>
<li style="font-weight: 400;">After each transfer, the remaining balance of your account must more than 61 CKB or you should clear it all</li>
</ul>
For example,
<ul>
<li style="font-weight: 400;">If your wallet totally has 200 CKB, the amount you can send out is 61~139, or send them all.</li>
<li style="font-weight: 400;">If your wallet totally has 120 CKB, you can only choose to send out all 120 CKB, and cannot send other quantities because other quantities cannot meet the above two conditions at the same time.</li>
</ul>
Steps to clear your account:
<ul>
<li>Input the receiver’s address and set the miner fees</li>
<li>Click the balance and it fills the amount automatically</li>
<li>Click the ‘Next’ then enter the correct password</li>
