Hi,
I’ve been trying to implement canceling transaction functionality for Nethermind client.
Basically - sending the same transaction once again with an increased gas price and 0 value, however I’m getting an error:
{"jsonrpc":"2.0","id":"0x1","error":{"code":-32000,"message":"nonce too low"}}
Is it possible to “update” the transaction (e.g. increase gas price) using the same nonce, in order to cancel/boost pending transactions?
I just tested a couple replacement transactions and they have worked for me. Are you sure the transaction was still pending when you tried to replace it? You cannot replace a mined transaction. Trying to send a transaction with a nonce number that has already been mined will result in a “nonce too low” error. Is there anymore information you can provide?
