Transaction Invalid

[bigbill223]

new to this site, been using electrum for a couple of years now. I send and receive coin to this wallet from different coin buying sites. Coinbase I've always used and never had any issues. I try to withdraw from my electrum wallet to my Coinbase as I do for trading. its been about 2 days and it still says pending on Coinbase, and when I click to view on blockchain. blockchain says: "Transaction Invalid; some inputs that it attempts to spend have been already spent or are no longer valid."

I'm not sure what I did to make this happen but I only do one receiving or withdraw at a time. OI haven't tried withdrawing anything else since I tried this transaction. If there is any information you guys might need to further help me please let me know. The amount I was transferring was roughly $100. USD

thank you in advance.

The transaction is not valid on blockchain explorer you used because the transaction has been dropped from some mempool, but that does not mean your wallet has not rebrocasted the transaction which will be valid on some mempool. You can try to use other blockchain explorer for it. But, that is not the matter, the fact that the balance not yet appearing back on electrum, it means the transaction is still very valid and yet not dropped from some mempool.

Make sure you check if the bitcoin has reappeared on your electrum wallet balance. If so, try to rebroadcast the transaction with high fee spending the same input you first used.

Or, on your electrum wallet, is the transaction still unconfirmed in the transaction history?
Is the transaction supporting replace-by-fee?

Or, can you paste here the txid? Although this can compromise your privacy but not you wallet security.

I just want to know if it support RBF, so that you can pump the fee if yet remained unconfirmed on your transaction history.

thank you for helping. I went to the transaction but the broadcast button is not clickable. the replace-by-fee says false, and my wallet balance reads: Balance: 0.00161481 BTC (89.33 USD)  [-0.00161481 unconfirmed] 1 BTC~55,317.26 USD

is there something else I could send besides the txid?

is there something else I could send besides the txid?

Yeah. Check the fee rate in Electrum by double clicking on the transaction. Also, the unconfirmed transaction will say something like "x.xx MB from tip", paste that value too. Those are your fee rates for that transaction.

While I doubt you manually changed the transaction fees, the network has been extremely clogged today and transactions with otherwise normal fees are as much as 20MB away from the tip.

Note that the information you have provided so far (estimated time of broadcast and total input amount) is enough to locate your transaction, so if you don't want to share your transaction ID for privacy reasons then you should also delete the information you have provided.

I have located the only transaction currently in the mempool which fits the information you have provided. As far as I can tell all the parents are confirmed, there is no double spend attempt, and none of the inputs are invalid. I do not get the warning you did when looking it up on blockchain.com. The fee is very low, however, around 40 vMB from the tip of the mempool, so you will likely be waiting a week or more for it to confirm.

thank you guys. what youre saying makes sense. I'm not able to change the transaction fee and if @o_e_l_e_o is right about it coming in about a week then I can wait for it. appreciate the help and figuring out that it was an invalid transaction. either really low fee/clogged network.

appreciate the help and figuring out that it was an invalid transaction.

I found your transaction.
As stated by o_e_l_e_o, it's not invalid. None of inputs have been double-spent.
I just accelerated your transaction using ViaBtc Accelerator. There's a chance your transaction will be confirmed in a few hours.

WTH!?! you can do that? that's awesome

I found your transaction.

Then why blockchain.com says it's invalid! Is it possible he replaced the original transaction by bumping the fees and the one you and o_e_l_e_o are looking at is the second transaction (the one with higher fees)?
Is there a way to check this? although a bit ot?

WTH!?! you can do that? that's awesome

Viabtc and other services offer accelerating low-fee transactions by including them in the block they are trying to solve. But you have to hope they will find the next block before other pools.

However miners prioritize transactions based on their paid fee, they are able to include any transaction they want.
ViaBTC (as one of mining pools) allow people to submit any transaction paying more than 10 sat/byte on their free accelerator,. They accept 100 transactions per hour.
If you submit your transaction on ViaBTC accelerator, your transaction will have the chance to be picked by ViaBTC in the next block they mine.

Whether your transaction is included or not depends on your luck. ViaBTC may find the next block in a few seconds or it may take more than a day until they find a block.

According to the data displayed on ViaBTC homepage, their hashrate is now 15.14 EH/s.
The total hashrate is now about 156 EH/s.
Therefore, it is estimated that ViaBTC can find one block in every 100 minutes on average.

Then why blockchain.com says it's invalid!

I don't see any message saying the transaction is invalid.

Is it possible he replaced the original transaction by bumping the fees and the one you and o_e_l_e_o are looking at is the second transaction (the one with higher fees)?

That may be the case.
The transaction I found is not flagged as RBF.
Perhaps, OP bumped the fee and checked "Final" option when increasing the fee.

Edit:
The transaction is now confirmed.
bigbill223, you should see the balance on Coinbase now.

FWIW, that is the warning which Blockchain.com displays when any transaction has been purged from their explorer. It is wildly misleading as more often than not, there isn't any conflicting transactions of that sort. This has been going on for quite a while, do try to avoid using their block explorer.

Then why blockchain.com says it's invalid! Is it possible he replaced the original transaction by bumping the fees and the one you and o_e_l_e_o are looking at is the second transaction (the one with higher fees)?

That was possible, yes, but I checked across multiple explorers and nodes and as I said only found a single transaction fitting the criteria OP gave with no evidence of a double spend anywhere. And as ranochigo says, blockchain.com's error messages are often wrong. It's one of the worst explorers, and I would encourage people to stop using it.

The transaction in question has now confirmed thanks to hosseinimr93's acceleration, so if OP is still having issues I'm sure he'll come back and let us know

[bigbill223]

it came through just as you said. really appreciate the extra push you put on it. and all the info you guys have told me. I just learned more about transactions than I did before.
