Yeah... the combined fee rate paid for both transactions works out to ~111 sats/vbyte... mempool.space is currently showing that as being effectively within the "next block" fee range (assuming there isn't a massive dump of super high fee transactions before the next block is found), so I would expect it to get a confirmation in the next block or 2.


It just missed the last block a couple of minutes ago by ~2 sats/vbyte Roll Eyes


EDIT: OK... so I was wondering why it hadn't confirmed when blocks were confirming with fees under 100 sats/vbyte... then noted that one of the UTXOs for your "first" transaction is actually from an unconfirmed transaction Undecided Roll Eyes

specifically this one: https://blockchair.com/bitcoin/transaction/2940b2f50cfaa5768a81dc3ab780853e1be5c413bee09d29d7b8dcef97c4c159#o=0

Unfortunately, this transaction is only paying 9 sats/vbyte... and is quite "large" from a data size perspective... Undecided As such the effective fee paid across all 3 of these transactions is:

(0.00004464 BTC + 0.00012460 BTC + 0.00019360 BTC) / (( 2025WU + 708WU + 437WU) / 4)
=> 36284 sats / (3170WU/4)
=> 36284 sats / 792.5 vbytes
=> ~45 sats / vbyte Undecided

Granted... it's better than 9 sats/byte... and it's currently within 4meg of the TIP... so maybe an hour or 2 if you're lucky.

Yes, that appears to be the reason for the apparent delay, but alas, I hope it will come through soon.

Thank you all for your suggestions!

I have now accessed my Coinbase wallet from Electrum and rerouted the transaction with what to me appears as a decently high fee and I am now waiting for confirmation.

https://blockchair.com/bitcoin/transaction/c98f7b0f7590287621f213d0cafb77e97951548cd1dc272e5b2b36467816c446

Could this procedure increase the estimated time necessary, other things being equal?

The thing is, there is no central mempool, every nodes with full blockchain that verify bitcoin trasactions have its own mempool, and these nodes communicate with other nodes and pass blocks mined and transactions already confirmed across for verification in which mempools are also updated. You transaction might have left some mempool, but that does not mean it is not still included in other mempools. Even, that is why there can be transactions that is already dropped and yet later confirmed after 14 days, the reason to rebroadcast exactly the same input that was dropped. In your case, the transaction has not being dropped by most mempool.

Which wallet did you send the transaction to? If you are able to spend unconfirmed transaction on the wallet, you can send to another address on your same wallet using input from the unconfirmed transaction. If high fee is used, the transactions will be confirmed earlier.

Thank you for the swift response.

While yes, I am familiar with the decentralised nature of mempools to an extent, so I was simply referring to the collective multitude of them.

As for my destination wallet, it is Coinbase wallet for Android, and I do not have the ability to spend unconfirmed funds.

It is not a matter of utmost urgency, but I do not want to simply leave the funds in limbo indefinitely. As an experienced user, do you think I could expect the transaction to be dropped in the coming days or weeks, or should I seek another avenue to resolve the situation?

All the best.

Greetings,

I am quite a fresh user of BTC, and it would appear that I have accidentally set an extremely low fee of 8 sat/B while transferring funds between two of my mobile wallets on separate devices.

Considering that two weeks have passed since the transaction was added to the mempool, I have decided it might be best to wait
until the transaction is deleted and then to restart it with a higher fee. However, it seems that I am beginning to exceed the time frame in which that is supposed to occur.

Could anyone please see if the available data indicates when the network should drop the transaction?

The transaction in question: 2940b2f50cfaa5768a81dc3ab780853e1be5c413bee09d29d7b8dcef97c4c159

(The transaction was sent from Mycelium Wallet on Android.)

Kind regards.
