Title: Tx Id 0/unconfirmed, not in memory pool 2 years ago...
Post by: JohnnyBoyI on January 03, 2021, 07:26:51 PM
Help - I am the recipient of a transfer that was never received from 2 years ago. It shows incoming to my Bitcoin Core Wallet but status is 0/unconfirmed and not in memory pool. The tx id does not show up on blockchain and other sites as if it does not exist. But again it shows incoming, is it possible sender sent transaction then double spent or completely low balled fee to void transaction? Wouldn't that still show a record of txid?? I have also been researching CPFP but cant figure out how to execute it in BC. Any ideas or Help would be greatly appreciated!

Run bitcoin core with -zapwallettxes startup option. That transaction should disappear.
To do so, you can use the command below in cmd.exe

Code:
"C:\Program Files (x86)\Bitcoin\bitcoin-qt" --zapwallettxes=1

In CPFP method, you spend an output of an unconfirmed parent with a high fee. Since you haven't received any bitcoin, it doesn't make sense to implement CPFP method.

If you can't find the transaction ID on a block explorer and the receiving address of yours does not have any balance according to a blockchain explorer, then there is no balance.

It is very well possible that the transaction simply got dropped or that you are looking at a manipulated wallet file (did you buy the file?).
Just check the address on a block explorer. If if shows no balance, there is no balance.

Zap -I looked into that method but concern is I would lose any info pertaining to transaction. Would I still be able to restore transaction from a backed up wallet?
CPFP - Since I am the receiver I am willing to spend higher fee - Is there a way to run that in BC?

The transaction does not exist.
It either got dropped 2 years ago or you got scammed by buying a wallet file.

No, since the transaction does not exist you can't do anything.
You never were in possession of these funds. And a CPFP won't help you.

Yes I'm starting to think it was a scammed fake wallet I purchased years ago. Just trying to rule everything out before I give up. Thanks

If you bought that wallet you've been scammed with a fake wallet there are many out there selling wallet.dat files with balances but the fact is no one will sell if they know that wallet has a large amount of Bitcoin.

I hope you learn about this experience next time don't buy manipulated wallets they always do this just to get some penny. The large seller of these fake wallets is in onion sites that you can only access through TOR so it's hard for them to take down.

You can decode the aforementioned transaction's "RAW Transaction" to totally rule out that it's a dropped or an invalid transaction by checking the inputs that it used.
You can get the raw txn by going to the 'transactions' tab by right-clicking the txn and selecting "copy raw transaction".
To decode it, go to the console (Window->Console) and type decoderawtransaction <space> your copied raw transaction,
eg.:
Code:
decoderawtransaction 0100000001e8bbee2adf46abe81d720b78ea355237bbb652955b1bf99d400d3e7e5e386d12......long string...
Then check the inputs' TXID under "vin", you can use a blockexplorer to see if they are valid or already spent.

BTW, if it's labeled as "Mined" in the 'Transactions' tab and you didn't mined before, then it's the fake wallet.

With a little work, you figure out what happened to the bitcoins that you were supposed to receive.

Look at the inputs of the transaction. There will be addresses and amounts, or (even better) transactions and indexes. Look up those addresses or transactions in a block explorer to see where the bitcoins that were supposed to be sent to you actually went. If the coins were sent somewhere else, then you probably won't be able to find out where, but you can find out when.

Then check the inputs' TXID under "vin", you can use a blockexplorer to see if they are valid or already spent.
Or you could just use the sendrawtransaction along with the raw transaction hex and see what error code is returned ;)

If it says "missing inputs" then either they've already been spent, or the wallet.dat might actually be for an altcoin and not Bitcoin. As per my other post (https://bitcointalk.org/index.php?topic=5306306.msg56043978#msg56043978), open the wallet.dat with a text editor, search for "name" fields and see what addresses you find... if they don't start with a "1", "3" or "bc1", then it's most likely an altcoin wallet.dat

What wallet is it? Is it a hardware (physical) wallet?

It is possible that you just set a too low fee and the transaction just dropped off. Where did you sent that bitcoin from? Was it from other wallet that you own?
