Anyone have experience with over writing a transaction? Earlier today I was trying to withdraw some PRL from Kucoin. It wasn't working so I hit refresh and without me realizing it switched to withdrawing KCS token. I quickly realized I had sent the wrong token and contacted support but they say there is nothing they can do. The transaction says it is still processing. From what I understood if another transaction is sent on that nonce with more gas it can overwrite the first. Is this true? I looked up some tutorials but wasn't sure if I could send another transaction without access to my private key or not. From what I understand since it is being sent to a PRL wallet the KCS tokens will be forever lost if sent, correct? If it is stuck in processing too long will the transaction expire and revert at somepoint? Any help would be much appreciated.
