about unconfirmed transaction

[howjow2]

The problem is not there. I've seen in the last 12h at least one block with 30-ish fees.

The problem is that the transaction has 2 unconfirmed parents (45187fd8c235887fcf7afe93985c727d8dd2238be2a83817d681216d4fda37f8 = 10 sat/vbyte, dbea9c449d4ec4b3719cece14ea515430ea14f7f68ac757b07de98aa7965068f = 5.9 sat/vbyte) and both of them has at least one unconfirmed parents (659abc5c3cf1fa765720d68518767a0815df4859ff1369a89a9b13d65b36c0e0 = 10 sat/vbyte, +3 more) ... I went to a good number of levels back and I keep finding unconfirmed parents.
So it's going to take a good while until these will get confirmed, if ever.

Nailed it. Only way now to rush all of these is for the guy sending you the transaction to make sure he uses his next one linked similarly to pay for all his previous ones. CPFP.

The only thing I'd say here is he does also have a history going farther back of confirmed transactions all on more or less small but not unusually small sat/byte fees so he's probably just happy to wait the mempool slug out, while paying on from unconfirmed inputs. Probably what I'd do since I trust the network that much;)

I'd just wait it out and ship once confirmed.

i just found out that my wallet is custodial since i had never heard that therm i had to search a little, but its one of the few trustful sites that offers such a service in my country. What i could notice is that the payer alleged that he is not able to boost that fee even after i offered him some money but now with the mempool space site i could find that the tx allows RBF...

You better need a noncustadial wallet. Electrum is a good option.

5.9 sat/vbyte

I did not check those parent transactions and it seems this 5.9 sat/B will take ages to get confirmed means all the child transactions are useless with whatever higher fee they have. Hopefully howjow2 wil not have bitter experience.

@howjow2, have you shipped the gold you sold yet? If not then wait until you get at least one confirmation. It's safer.

Honestly im quite pessimist atm, even though he had a history of low fee transactios, like mentioned, i did not see any that got canceled, do they get cleared? and if any of you guys are curious in the case, we are lacking contact from the payer rn also im in contact with at least other 3 guys involved in the case, we are running a dispute on the gaming forum due to the fact the buyer was a very trusted guy who has been on the market for quite some time and has had a history with high ammount trades,  apparently what happened this time is that even though my ammount wasnt that high, a few other dudes handed him about 15k usd in "ingame currency" and he got ambitious. Anyways i'll just move on, lesson was learned at least, im extremely thankful for all the precious information you guys shared with me, its helping me to prove he is a bad person and wont be able to do business with anyone else in that forum!!

Hihi, I've managed to sneak two of them into viabtc accelerator, but only 3 of those have a fee high enough to get accepted into, and for the third one I was too late.
And of course, they've mined two blocks just 20 minutes ago but let's see how the fee math changes after those two are getting confirmed.

I just hope I've grabebd the right one as I was in a rush seeing the clock at :58

wow sir!! that might be a light, both tx you posted got 2 confirmations already!!

Sorry I was away last two day. What is your update? The Transaction ID is still unconfirmed. Did you guys able to talk to the seller or already a dispute running?

[faithwin]

I'm in the same predicament of unconfirmed tx. Mine is worse though because it has a very low transaction fee... which was the regular recommended price in the blockchain.com wallet at the time. The worst part is of course since it's a blockchain.com wallet, I can't do the RBF and the fee is soo low that ViaBTC won't accelerate the transaction...  I'm new to cryptocurrency but have done quite a few transactions and this is the first time I'm encountering this issue.

My transaction has been unconfirmed since 15th Feb...
txid eb8d25f15ff864c1cb58d093465adbc51459ddeae3ca2250e82c6cb3ff66544d

All I can do or started doing is trying to get it rebroadcasted at https://btcnitro.com/# every 6hrs

At this point, I don't know what else to do... I checked at https://pushtx.btc.com/ to see an estimate, to get it pushed up and it gave me an estimate of $210+ USD🙆😱. Any suggestions... I'm open to any suggestion at this point.

-snip- and the fee is soo low that ViaBTC won't accelerate the transaction...

Not too low but it's only 20satoshi short to reach exactly 10sat/B for Viabtc's free accelerator, that's unfortunate.

Doing a CPFP will do.
If one of the two outputs is your change, all you have to do is to spend it with a relatively higher fee than the recommended.
Problem is your client, blockchain.com doesn't have "coin control" to be able to select inputs.

If you don't have other unspent transaction outputs (inputs) in your blockchain wallet, any new outbound transaction will be considered as CPFP because it will guarantee that the change of the "stuck txn" will be spent.

Alternatively, if your have other inputs, you can import the wallet's "recovery phrase" to Electrum and spend that transaction's change using these tutorials:

• Restore the backup phrase: https://bitcoinelectrum.com/restoring-your-standard-wallet-from-seed (read note on step4)
• Use Coin control: https://bitcoinelectrum.com/how-to-spend-specific-utxos-in-electrum/

Please be careful with the recovery phrase, read the warnings. Compromising it will lead to loss of funds.

[o_e_l_e_o]

To add to nc50lc's reply above:

Your current transaction is 521 vbytes and pays 5,190 sats in fees. If you send your change output to another legacy address you control, this transaction will be in the region 192 vbytes, giving a total of 713 vbytes. Currently, to get confirmed quickly you need to pay around 40 sats/vbyte, which would be 28,520 sats in total. This means your CPFP transaction would need to pay 23,330 sats in total for the fee, which would be a rate of around 122 sats/vbyte.

Obviously this could all change at any time depending on what the mempool does.

If I understand you correctly.. Unspent - do you mean if I have funds in my blockchain.com wallet? And by (any new outbound transaction) do you mean other transactions out of my blockchain.com because since 15 Feb I sent two transactions from the same wallet to other external wallet and they were confirmed relatively quickly. I was hoping those transactions will trigger something to make the unconfirmed transactions be confirmed... or Am I getting it totally wrong..?

I might have to try this out... I really appreciate your help thank you so much.

Okay, since the two transaction after the stuck one were already confirmed, then it's change must have been left unspent by the wallet, those didn't affected the stuck transaction at all.
Because if its change was used, the transaction that spent it must be mined together in a single block (at the same time).

In the "coin control" step, you must select the change of the stuck transaction because if the wrong coin was spent, it won't be considered as CPFP.
To check the change, find the 'stuck' transaction in the history tab and take note of the details specially the txid and the address which will be displayed as "output point" and "address" in the 'Coins' tab.

[NeuroticFish]

Just a heads up, ViaBTC has mined this tx about one hour ago. It has 10 confirmations now.
So after all we have a happy ending

There is no need to use "Coin Control" feature. It may be difficult for a newbie.
The easiest way to implement CPFP method in electrum is to right-click on the transaction and select "Child pays for parent".

For some reason, it wont appear in the "sender" Electrum even if one of the outputs belongs to that wallet, tested in testnet Electrum v4.0.9.
So if it doesn't appear at his end, he must use coin control.

Wasn't the transaction you made for testing RBF-enabled?

If the transaction has been flagged as RBF, you won't see "CPFP" option in right-click menu and you will see "Increase fee" instead of that.
If the transaction hasn't been flagged as RBF, you should see "CPFP" option.

yes!!! finally hehe, i'll make sure my next deal in btc has a great fee talk involved haha

btw, would eth be a decent alternative for times when the network is clogged?

Thanks so much for everyone who stopped by here, i learned so much in this forum already!

[nc50lc]

If the transaction hasn't been flagged as RBF, you should see "CPFP" option.

That's it, so Electrum will automatically disable the feature when RBF is available, that's a well-thought feature.
Must be because it's not efficient to allow the sender to create another transaction to accelerate the one that can be RBF~ed.
I haven't tested that factor, thanks.

Anyways, the CPFP will only able to send to his own wallet, being able to use 'coin control' will allow him to use the coin for his next payments/transactions instead of sending back to himself.

In terms of dollars equivalent, yes for now.

Hey ya'll my transaction finally confirmed!!!

Thank you everyone... this forum has taught me so much... and I'll continue to learn... thank you, you're all legends!!

[zaeek]

Hello, here is around 6 days, I bought some bitcoin, after they sent them, I did not receive anything because the transactions remain unconfirmed for 1 week.
In addition, only one of the two appears in the blockchain, one of the two seems to be in another blockchain (mempool)

Transaction number 1:
Here is the transaction (it appears in my wallet as unconfirmed):

https://blockstream.info/tx/6cdb98f9c86ef7902ee991d44e013307662086322dc41ee392584daac8b12d11

transaction number 2:
this one (it doesn't even appear in my wallet):

https://blockstream.info/tx/b405185bc699d24a611cb25aeb3347159235c968bbb0d58a8c98cc1b96cd6ccf

The fees are + 0.0007 BTC (100.1 sat / vB) (around 25 €)

Can someone help me and find out where the problem is coming from.

What if there are minors, if you could unblock the situation: /

I need help guys, need to pay my friends/worker :S

The problem is: despite the very high fee rate of those two transactions, their parent transactions are both unconfirmed with very low fee rate.
So miners are considering them as "bundle" parent and child transactions, and the fee rate will be based from their total size and fee.

Your transaction: 6cdb98f9c86ef7902ee991d44e013307662086322dc41ee392584daac8b12d11 with 100.1 sat/vB fee rate has two inputs which are both unconfirmed, namely:
1. 0ba52bed104cea1075754f783867d423ae9510bd4d6fb3f3905aaf7e1862fd9d @ 7.0 sat/vB.
2. fe682ab28ecdb3bc82498af0c7730e2fcb0cf8563c6fc88cc2367c16aa3624a0 @ 10.0 sat/vB.

Both the transaction's sizes are too large and the fee rate too low for the child transaction to accelerate them effectively.
let's say that there are no unconfirmed transaction in the parents' inputs (I didn't checked because there are hundreds of them),
the total size of the batch would be: 699 vB + 27904 vB + 16106 vB = 44,709 vB
then the total fee would be: 70,000 sat + 195,860 sat + 161,530 = 427,390 sat fee; that's a total of 9.56sat/vB fee rate[/b].
Currently, 9-10sat/B is @ 20vMB from tip of mempools.

The other transaction may be missing from time to time because the parent's input parent's fee rate range is beyond the default maximum size of mempools.

[o_e_l_e_o]

Yeah, you are kind of stuck with the one due to the huge size of the unconfirmed parents. To boost the entire fee up to somewhere in the region of 40-50 sats/vbyte, you would need to do a CPFP and pay a total fee of around 1,500,000 sats, or 0.015 BTC. And as with nc50lc, that assumes no unconfirmed parents higher up. Realistically, you are just going to have to wait for the mempool to empty for this to be confirmed.

If you have a copy of the second transaction then you can rebroadcast it. If not, you'll need to ask the sender to rebroadcast it.

[NeuroticFish]

If you have a copy of the second transaction then you can rebroadcast it. If not, you'll need to ask the sender to rebroadcast it.

Why would he need a copy of the transaction?
There are websites that re-broadcast for free (although the name would suggest accelerate) and all you need to know is the tx ID.
Of course, I don't own any of them and I don't know how good they work, but I think that it was bitaccelerate.com I've used once in the past and it worked.
