Hello, I hope this post will be useful for newbies. The situation, that happened with me.
Yesterday I tried to send some Eth on exchange. But the transaction didn't get through. It remained
pending in Metamask and on Etherscan for 5 hours! I thought I used too little gas fee. But I chose average gas fee, not lower. I cancelled that transaction and tried another one with the highest gas fee. And there were 2 transaction pending. One with o Eth and one with my Eth. With 0 Eth appoved in an hour and the other transaction remained pending for 3 hours... Than I cancelled that transaction too. I thought the network was busy and try again later. I tried another transaction in a few hours. But it haven't even showed on Etherscan. It was said the transaction is
dropped.
I surfed the net to find out the solution. And what do you think it was? The problem was with
Metamask. I reinstalled it and my transaction get through in 2 minutes. Amazed.
I spend some extra Eth on gas fee, so I hope you won't do my mistakes
