Transaction held for more than 2 weeks

[elpablito000101]

I made this deposit to mix over 2 weeks ago and so far it is in pending status, awaiting confirmation of funds, is there anything I can do to speed this up? Transaction ID below: 1974a514664a4815930de64fd33e2d40010949a8f6faf857a8bff3ca13e43f87

If anyone has an idea of what to do, please let me know.

I am in same situation. It has been 10 days for me.

[MarnixCroes]

It's working as expected.
The coinjoin is waiting for confirmation.
Mining fees went up significantly last few weeks, so the coinjoin is still in the "queue" waiting to get confirmed.
As there is only a fixed amount of space for transactions to get confirmed, so the highest paying ones usually gets confirmed first.
Like shown at https://mempool.space/

Currently, there's not much you can do to speed it up.
So you should just wait :(

tip: next you could use the Discreet Mode (left bottom) so you don't have to show you wallet history and balance.

I've always used it and it's never taken this long, this is scaring me. I looked for some acceleration services, but they are charging too much to do the service.

[MarnixCroes]

yes I understand, this is a rare occasion.

be careful with those, could be scams as well.

If you're really in a hurry you could CPFP with a coinjoin output, but it can be expensive to do it effectively. And there are no guarantees it will actually work. so you might just burn money.

[elpablito000101]

CPFP? I don't know what this is or how it works, could you please explain it to me?

So, from the tx you mentioned, the fee rate was 5.16 sat/vByte.
Some people already spent the unconfirmed coins in a new tx with a higher fee rate.
This results in indirectly also bumping/increasing the "Parent" transaction fee rate.

So effective fee rate now is 14.9 sat/vByte.
Which makes it more attractive to miners to mine these transactions.

[MarnixCroes]

FYI, before you try to do this, there are several nuances to be aware of.

[elpablito000101]

Can you help me try to do this? I'll pay you for your help, because I've never done this, I'm reading the topic you mentioned but as I've never done it it's a little complicated.

First generate a new receive address for yourself.
Then you can do it following this guide https://docs.wasabiwallet.io/FAQ/FAQ-UseWasabi.html#how-do-i-select-coins-for-spending, and selecting only one coin (maybe the highest one in value), then manually choose a high fee rate as described in this guide https://docs.wasabiwallet.io/FAQ/FAQ-UseWasabi.html#how-do-i-set-custom-fee-rate and set it to a high value according to https://mempool.space/ or whatever fee estimator you want.

For example at the current state of the mempool and using a fee rate of 116 sat/vB it would cost around $800 to do this.
No need for any payment for this information.

[MarnixCroes]

So you would have to send an unconfirmed coin from the coinjoin to yourself.
So you need to generate a new address and then send the/some coin(s) to there.
But you need to set a very high fee rate.
As the coinjoin is a big transaction (in size) and a "normal" user transaction is a smaller sized one.

These would be steps.

BUT, as I mentioned there is no guarantee it is effective, as this is basically just a workaround.
One big thing to keep in mind is that, afaik, the default Bitcoin Core client (which most miners run) only counts a single transaction chain for the effective fee rate.
So if someone else did the same as you, it might not have effect.
And you're just wasting money :(

Since the coinjoin contains many other participants, it's costly to use Child Pays For Parent to speed up confirmation because you will be paying for everyone's fee, not just your own. However, due to the large amount you have in the coinjoin, it might be worth it to pay this cost.

Here are the steps in case you decide to perform a CPFP to add the fees:

-First generate a new receive address for yourself.
-Then, open your UTXOs menu with the keyboard shortcut "CTRL + C + D" (or by searching 'UTXO' in the search bar at the top).
-Select the input for 2.05606646 BTC and use the "Send Selected Coins" button to spend that input to your own address you just generated, then edit the fee rate of your payment to be large enough to pay for the coinjoin.

How high of a fee is "large enough"? Here's some examples:

The base fee rate of the coinjoin is 5.16 sat/vbyte, which amounts to $35. It would cost approximately $210 to boost the fee rate of the coinjoin to 30 sat/vbyte, which would require the child transaction (which is approximately 110 vbytes in size) to pay a fee of about 5,000 sats/vbyte. In order to boost the coinjoin to 50 sat/vbyte, the child transaction would need to pay about 8,500 sats/vbyte.

Would it be more or less that to be able to do it?

No it should be something 20500, but as Marnix said in his comment this is risky and you might just lose your money for nothing:

In fact I checked some of the outputs of the unconfirmed coinjoin and many of them are spent in a long chain of transactions, unless you want to repeating doing CPFP for yourself like 10 times or maybe more idk, but the next CPFPs you can only use 120-130 sat/vb, so at the end it might cost more than $800. Ofc this can cost less if you wait for the fees to drop a bit.

[elpablito000101]

I entered a lower value, it didn't crash but it gave an error, it says I have unconfirmed transactions.

[yahiheb]

Did you select only one of those coins?
Anyway I don't personally suggest you to do that because the fees currently keep increasing.

[yahiheb]

The coinjoin transaction is now confirmed: https://mempool.space/tx/1974a514664a4815930de64fd33e2d40010949a8f6faf857a8bff3ca13e43f87

[elpablito000101]

Yes, thank you.

[elpablito000101]

Finally it was completed, almost 20 days, thank you very much everyone for your support.
