confirmTX scam... stop posting his url site!
you can download the source from github and run it offline,
but you still need to be online when retrieving utxo inputs and brodcasting the tx
Now I still have the paper wallet with the private key, and as far as I know I just need to rebroadcast the tx with a higher fee and it should get picked up and the other rejected. But I can't find a client that will allow me to do this as it shows the funds are currently spent.
have you checked/tried coinb.in? javascript web tool for composing, signing and broadcasting txyou can download the source from github and run it offline,
but you still need to be online when retrieving utxo inputs and brodcasting the tx
I actually did come across that site in my searches, but it tells me the input or output is invalid, probably because it shows as already sent on the blockchain.
