Thank you for the answer.I tried again but it failed with same notification. i have pending transactions in my metamask but in avalanche chain. does they can effect this transaction at main ethereum chain? ı cant move anything
You can try to send it again, your dadi is not going to the somewhere and that means your transaction is not yet broadcasted, as long as your transaction is not yet mined by the block and your funds will never be delivered to the destination address.
Try to create a new transaction again. If you are feeling difficult to use mew and you can try to use mycrypto.
