After you connect to an app with your wallet the app is able to request your permission to approve transactions. Always verify the transaction before approving it.
Avana Wallet simulates the transaction to show you the anticipated changes to your account. You can review account balance changes, as well as the transaction instructions.
Crypto transactions are not reversible, so double and triple check the information. Also, you should trust the site that you are using.
If a transaction times out or fails to confirm, always check your transaction history before attempting to resubmit the transaction. Resubmitting the same transaction immediately can result in an unintended duplicate transaction.
Wait approximately two minutes - if the transaction does not appear in your history then it should be safe to resubmit the transaction.
