Hi how i can mine my own pending transaction with my gpu on Ethereum network? please give me information.
You meant you wanna validate your transaction by your mining rig? i think that's impossible to do that. AFAIK your transaction can be placed into the various block and you can't specifically know which block that contains your transaction It should be random because when you become a miner and what you can do to gather the txs as much as the block can processing it. It's probably up to 15 TPS.
What you can do to replace it with a new transaction with greater fees.
