Not enough tokens to pay the fee

If you get the error "Not enough tokens to pay the fee – you don't have enough balance to pay the network fee of [amount] [token]. Available balance to pay fee after the operation [amount] [token]." This error is caused because each network may have a minimum balance that you have to keep. If your transferable balance falls below this amount (even temporarily) then your account is deleted from the blockchain.

In order to complete your transaction, you need to add more tokens to your transferable balance. You need to make sure your transferable balance covers the minimum balance PLUS the transaction fee.

For Polkadot:

Polkadot has a minimum transferable balance of 1 DOT. If your account falls below 1 DOT in its transferable balance (even temporarily) then your account is deleted from the blockchain.

In order to complete this transaction, you should make sure that you have 1 DOT + the amount of DOT for the transaction fee in your transferable balance. For example, you should have 1.1 DOT in your transferable balance.

In order to continue with the transaction, please add more DOT to your transferable balance.

I haven't received my tokens from a CEX

If you haven't received tokens that you have withdrawn from a CEX (such as Binance, Coinbase, Kucoin, Kraken, MEXC, etc.) it is typically because CEXs can face delays when processing both withdrawals and deposits – this can range from a few minutes to a few hours.

You should verify that the transaction has been finalized on the blockchain by using a block explorer.

I sent tokens to a CEX and they haven't arrived

I was scammed / someone stole my tokens

Nova Wallet is a self-custodial wallet solution, it means that your account and the tokens that it holds are fully controlled by your seed phrase. If you share this seed phrase with anyone, then they have full access to your account and can carry out any transaction, including balance transfers.

Nova Wallet never custodies your tokens for you, like a CEX might do, as such it is impossible for us to assist with asset recovery.

Additionally, it is impossible to reverse blockchain transactions.

If you still have any tokens on your account then:

1. Immediately transfer those tokens to a new account, you can see how to create a new account here:

2. If you have tokens that are currently unstaking, then you need to transfer them away from your account before the scammer does.

The best bet for you to recover any tokens that have already been transferred away from your account would be to check to see if the scammer sends tokens to a CEX, then you may be able to contact that CEX who may be able to assist you in asset recovery.

My tokens are gone / missing

If there are operations being carried out on your account, and you did not initiate them, then it means a scammer has control of your account.

Nova Wallet is a self-custodial wallet solution, it means that your account and the tokens that it holds are fully controlled by your seed phrase. If you share this seed phrase with anyone, then they have full access to your account and can carry out any transaction, including balance transfers.

If you have accidentally shared your seed phrase with someone, for example, someone impersonating an admin, entered it into a random website, or stored it in plain text on cloud storage, then an attacker can take full access of your account.

There is no price for a token

We currently use Coingecko for our Price Data Feeds, if the token does not have a price on Coingecko then we cannot show the price. If the coin you are asking about does have a price on Coingecko, then we will add it soon!

I cannot connect to a DApp

Nova Wallet allows you to connect to DApps using either the Polkadot JS or Metamask protocols. If you are trying to connect to a DApp but do not see the "Connect with Nova Wallet" option then you should select either the Polkadot JS or Metamask options

When will I get my airdrop from a project team?

For details regarding any specific airdrop such as the eligibility criteria or details regarding token distribution, you should contact the individual project team itself.

Nova Wallet is a self-custodial wallet, it means that you are in control of the assets on your account, and the Nova Wallet team does not hold them for you.

I cannot see a token in my wallet

There are a few reasons why you may not be able to see a particular token in your wallet.

Make sure the token is not hidden: Tokens / Networks View
If it is an ERC-20 or XC-20 token on an EVM network that Nova Wallet supports, then you should add information about the token by following this guide: Add Custom ERC-20 Token
If it is a brand new chain that has just launched, then we are likely in communication with that project team to add their chain and token to Nova Wallet. Feel free to reach out to that project and let them know that you would like Nova Wallet to support their chain chain/token!
If it is a new token on an existing chain, then we are likely in communication with that project team to add their chain and token to Nova Wallet. Feel free to reach out to that project and let them know that they should inform Nova Wallet about the new token!

How can I stake a token? / Nova doesn't support staking for a token

Nova Wallet currently supports staking for a range of tokens from our staking screen. If you cannot see the token that you wish to stake on our staking screen then you should contact that project's development team and find out how to stake the token. You can use the DApp site that they tell you to use from Nova Wallet's DApp Browser Search for a DApp

Can you add a feature / when will you add this feature?

We dedicate a portion of our development time to implementing community-requested features. Please leave your feature idea on our Canny page so that we can review it and hopefully implement it!

I cannot swap a token

Currently, our swap feature supports the Hydration Omnipool and Isolated Pools and the tokens that are supported there. If the token you are referring to is currently not listed on Hydration, you currently cannot swap into it using our native swap UI. We are working on improving this feature so that you can swap more tokens.

In the meantime, you can connect to the Hydration DApp from the DApp browser (or any other DApp/DEX) in order to complete your desired operation.

You can access a range of DEXs from the DApp Browser – you should ask the project team for the token that you want to swap for more details regarding which DEX their token is listed on, and then you can access that DApp from the DApp Browser Search for a DApp

Can I export my transactions as a CSV file?

Currently, Nova Wallet does not support this feature, but you can use Subscan.

Tap your address in Nova Wallet -> view in Subscan -> go to the relevant tab, for example, "rewards" for staking rewards details -> View all -> Download all data

Nova Wallet is not loading

If you have an issue where certain screens in Nova Wallet are not loading correctly then try the following:

Ensure that you have the latest version of Nova Wallet downloaded.
Fully close and reopen the app (don't just minimize it).
Toggle off/on any VPNs – sometimes VPNs can cause connectivity issues. Sometimes some ISPs in certain geographical locations such as Russia, Ukraine, China and India can cause connectivity issues which require you to use a VPN to resolve the issue.

If you are facing issues when connecting to a 3rd party DApp then you need to contact the development team of that DApp for more help.

Please synchronize my wallet

There is no such thing as synchronizing your wallet. The Nova Wallet team does not hold your tokens. Nova Wallet is self-custodial meaning that you control the tokens in your account by yourself. If someone is asking you to synchronize your wallet then you are being scammed and should immediately block and report that person.
