Hi guys, Got a transaction that I stupidly tried to make when my wallet was out by several weeks, so the fee it estimated was far too low, and the problem is now I have no way of cancelling it, I tried making another transaction and it just tells me my balance too low to do it.

I am using the Bitcoin core latest version

I actually put this through over 10 days ago, but now see the date has updated, my client shows a different date also.

I've tried manipulating the wallet with pywallet, I've tried to reset the wallet and rescan, I've tried to -zapwalletxes and nothing is working. The abandon transaction is also greyed out and enabling coin control makes no difference.

Every time I restart the bitcoin client, the transaction re-appears with today's date and time, so a different approach has been just not going back into the client for a few days, since the 20th to be exact, and now still it's unconfirmed and will not give up.

Any ideas?? Very frustrating as was wanting to buy some Ether :(

Shut down Bitcoin Core. Find the Bitcoin Core datadir. Delete the file named mempool.dat. Open or create a text file named bitcoin.conf (.conf extension, no .txt extension). Add the following line to the file:

Now start Core. You should be able to do Abandon Transaction now.

Once you create your double spending higher fee transaction, stop Bitcoin Core and remove the line you added to the bitcoin.conf file.

You are a lifesaver, nobody else seemed to know how to do it and I could not find this information anywhere else, thank you!

Worked for me as well thanks!
