[GUIDE] Delete your 0/unconfirmed transactions in 30 seconds

[shahadil]

I did all the steps as pointed out, but now get a message when i send a transaction that this is a potential double spend and the transaction is being rejected by the client.

It's polite to warn that yours is a necropost .

Wait some hours/days until the network forgets about your previous attempt. Then broadcast the new transaction.

I am sorry about that, had to look up the meaning of the word. Shall never happen again. So I guess I shall keep trying everyday to send and see what happens.

no miner fee, double spend or anything is not valid in terms of transaction specs may cause unconfirmed transactions.

Has anyone tried this guide recently?

I tried the -zapwallettxes feature of the Bitcoin QT wallet, which does the exact same as the python trick: the unconfirmed transaction is gone from your wallet, and your balance seems to be restored.

BUT it won't allow you to double spend your bitcoins, you still need to wait for the network to drop (or confirm) your initial transaction.

I now really start to like this 'replace by fee' suggestion, there is a clear need to be able to increase the fee in case your transaction does not get confirmed quick enough.

C:\Program Files\Bitcoin>bitcoin-qt.exe -zapwallettex doesn't seem to work on my Testnet wallet. I have a zero conf tx (mh1BnfNWBi6tY1RCC7vEu5DwCqDqKdVC2A) and it's still there in my transaction history. The testnet coins are somewhere in cyberspace now...

Any other methods, next to pywallet?

What about if using blockchain wallet. Is there anyway to delete transaction or maybe push it

IIRC, Blockchain.info does not rebroadcast transactions after it gets dropped out of mempool. You can push the transaction by getting the raw format at

Code:

https://blockchain.info/tx/[insert tx here]?format=hex

copy the entire thing and go to

Code:

https://blockchain.info/pushtx

and paste the entire code.

This means that your transaction has not dropped out of mempool. If it does get dropped, your transaction would be forgotten by the network and you can create another transaction with a higher fee. If you rebroadcast it again, it would stay in the mempool till a miner includes it into a block or it drops out again. The longer you wait, the higher the possibility of it getting included as a free transaction as the priority will rise due to the increasing coin age.

cool thanks im gonna check this out

So this could be a way to delete unintentionally sent transactions? The only thing it needs is that it should have 9 confirmations, right?
But this methods could than be used as a scamming method too...

This is a way to delete transactions that are still shown on your client. The transaction should not have any confirmations for it to work and the mempool should have dropped your transaction already. AFAIK, only one doublespend was successful and it was during the march 2013 fork, the money was returned.

This has happened with me also twice. This problem arises just because of network issues at that time, and what happens is that one transaction is displayed twice. This can be solved easily in most cases by a heavy refresh of your wallet,  and if that doesn't solve, just make a new transaction, it will do a force refresh and probably fix problem. Alternatively, in last option you can contact your wallet provider for assistance. This will surely solve it out.

Do i really need to wait 3-5 days till my 24hours still unconfirmed transaction is cancelled?
Is it possible to delete it using electrum wallet?

does the network kill transactions that are hanging around forever?

That transaction has 2 other conflicting transactions spending a few common inputs. Only one of them would get confirmed eventually. AFAIK, there isn't anyway to delete transactions from electrum.

Transactions will eventually drop out of the mempool if they get unconfirmed for too long and the user can reinitiate another transaction from the same input. It isn't the case for wallet which automatically rebroadcast though.

According to the wiki it should be -zapwallettxes=<mode>

Ultimate way to delete your forever unconfirmed transactions

• Backup your wallet just in case
• Download Pywallet
• Run './pywallet.py --web'
• Go to http://localhost:8989 in your browser
• Fill the Delete form like this:
  
  
  • Wallet Directory: /your/wallet/directory
  • Wallet Filename: yourwalletfilename
  • Key: all
  • Type: leave 'Transaction'
  
  
• Click the Delete button
• Run 'bitcoin -rescan'
• Done, no more unconfirmed tx's

there is a way to make the same operation with multibit?
I need a backup every tx that I delete or just private key one time (first use!)?
