bitcoin unconfirmed 6 days - can't do CPFP says mempool too large.

[o_e_l_e_o]

whats the deal

The deal is that your transaction is third in a chain of three unconfirmed transactions, meaning your transaction cannot confirm until the other two also confirm. With an effective fee rate of 82.8 sats/vbyte, it is unlikely to confirm any time soon.

None of the transactions are flagged as RBF so you cannot use that. Since your transaction has an unconfirmed parent, you will not be able to use ViaBTC's free accelerator. Your options are then as follows:

• Be patient and wait for the mempool to empty down to the required level, which will likely take a week or two.
• Accelerator the first transaction in the chain using ViaBTC's accelerator. Once it has been confirmed, accelerate the second one. Once it has been confirmed, accelerate your one (or more likely your one will have a high enough fee to confirm on its own at that point). This will be a difficult task.
• Perform a CPFP with the output. The output to your transaction has over 0.011 BTC in it. Whoever owns that output (be it you or someone you were paying) can perform a CPFP with it. However, since you will now be paying a fee for 4 transactions, the fee will be significant. (Assuming a 1-input-1-output legacy child transaction of 192 bytes, to reach a total fee rate of 200 sats/vbyte your CPFP transaction would need to pay a fee of 102,960 sats, which would work out to ~537 sats/vbyte.)

ok i tracked it down theres 2 tx i found his wallet has unconfirmed
sent to me my tx unconfirmed

so theres 2 unconfirmed TX

i need to accerlate his first one then mine?

i need to accerlate his first one then mine?

You have to accelerate all the transactions your transaction depends on.

So if your tx is "third in chain" then it means that your tx parent's unconfirmed parent needs to be accelerated first.
Then wait unil that one is confirmed.
Then accelerate your tx unconfirmed parent. Then wait until it's confirmed.
Then accelerate your tx.

If you enter your tx at https://mempool.space you'll find easily which are the unconfirmed parents (go backwards via the red arrows from the left side)

so i guess 7 days not enough i need to wait 1-2 weeks?
is there any other ones besides viabtc to confirm it
i tried btcnitro and bitaccelerate daily still doesnt get confirmed

i tried btcnitro and bitaccelerate daily still doesnt get confirmed

Those are just rebroadcasting services, they do nothing to confirm your transaction, they are not mining blocks, and don't have a deal with mining pools. In short, they are useless.
As for the waiting period, it's not going to be that long.

The deal is that your transaction is third in a chain of three unconfirmed transactions, meaning your transaction cannot confirm until the other two also confirm. With an effective fee rate of 82.8 sats/vbyte, it is unlikely to confirm any time soon.

There are chances it's going to be sooner than that, all signs point to mining having resumed in china, 143 blocks in the last 24h hours yesterday at around the same hour, and 140 now, the fee required for confirmation has also dropped a lot, we were in the 200+ area and now we even dropped to 100sat/b last night, the weekend is coming so if the overall fee is indeed 82sat/b assuming nothing major happens there are some chances it will get included late Sunday/early Monday.
The distance from the top went down for an 80sat/b from 23M to just 9M in 24hours, the mempool is getting cleaned.

ok just make sure my btc wont just drop off and get returned if it doesnt confirm too long would it?

Yes, that's exactly what would happen. The default_mempool_expiry time is set to 336 hours, which is 14 days. This means that most nodes will drop transactions which remain unconfirmed after 14 days from their mempool. If the transaction is dropped from the mempool, then the bitcoin are effectively returned to the sender's address and they can do what they like with them. The way to avoid this from happening is to keep rebroadcasting the transaction (and its unconfirmed parents) until they are all confirmed.

7 days unconfirmed
whats the deal could i pm someone my transaction id get this confirmed?

I can try to help, but first you need to send me your transaction ID to find out what fee is set on the previous two transactions on which your transaction actually depends. If it is not less than 10 sat/byte it will take time, but it is feasible.

As I said above, the combined effective fee rate for these three transactions was 82.8 sats/vbyte, which is now far above the required fee of 50 sats/vbyte which is being processed, as it seems the hashrate had picked up again in the last day or two and the backlog is starting to clear. Indeed, OP's transaction and its two unconfirmed parents all confirmed in the same block around 18 hours ago.
