Hello,
I have sent a 0.2805BTC transaction on 19/04/2013 and is basically stuck (has 0 confirmations). How can I get this added back into my wallet balance?
Untried. But *should* work without using any non-standard tools and without risk to your existing wallet. (Note step #2 !!!)
1. Export the private key which was the source of the funds for the $0.2805BTC transaction.
2. To be safe,
use a different computer for the following! I'm not responsible if you mess up your original wallet!
3. Create a brand new wallet
on the different computer.
4. Import the private key you saved in step 1. With most wallets, the import should kick off a rescan of the block chain.
5. Assuming the client running your new wallet isn't talking to the client running your old wallet, the new wallet will only see what's in the block chain. (And you say the blockchain still has your $0.2805BTC.)
6. Send the money from the new client. You can send it back to yourself or you can send it to the originally intended address.
7. When the transaction created in #6 gets some confirmations, the original transaction will become a failed "double-spend" attempt. All should be well.
Good luck.
[Edit:
Revised #6. Send *all* of the money from the new wallet back to yourself. (To a receive address known to the old wallet).
Otherwise, be aware that your new wallet may send change back to a (possibly hidden) address known only to the new wallet. Be sure all the expected money appears in your old wallet before you even *think* about destroying the new wallet. You may need to explicitly send the change seen only in your new wallet to an address known to your old wallet.]
