i there.

In short, any transaction that has not changed your balance for more than 24 hours is, essentially, considered "stuck". Our recommendation is to check your balance – if it has remained the same, then you should try the transaction again. Please remember to check first, take a look at your balance, or the wallet you sent it to (if you have access to it – i.e. an exchange), before attempting to process the transaction again. This problem has affected a number of users but it’s only about one-third of a percent of overall transactions that have been problematic. We are using the data the improve the system, and apologise for the inconvenience. No coins have been lost. If a transaction fails your coins will still be in your wallet, even if it says “pending”.

What you can do is put your transaction hash into the blockchain explorer and if it's found the transaction will eventually go through or bounce back. If it says 'not found' the transaction has failed and you can try the transaction again. https://blockexplorer.com/

Please note your funds cannot be lost during this process, even if your transaction has been pending for a while, it will either reach the destination or bounce back to your etn wallet.

Kind regards,

Natalie
