Help with Bitcoin Core Transaction

[TallblokeUK]

Over the weekend I was 4000 ish of 5000, I was referring to the number of transactions dropping to 5k being close.

I get how it works

Over the weekend I was 4000 ish of 5000, I was referring to the number of transactions dropping to 5k being close.

And now the number of unconfirmed transactions has spiked again and is over 40,000... with the associated increase in fees. I hope you brought a change of clothes, it's going to be a long wait

[TallblokeUK]

Haha, well... I'll give it another weekend at least

You could abandon the transaction and create a new one with only some of the bigger inputs once it drops out of mempool.

Morning all!

So I'm still languishing in the mempool, with a lot of other low fee transactions by the looks of things.

Is the fact this link https://blockchair.com/bitcoin/transaction/ecb4d354df52519538a47f930e5b715a097c07fa4863b06a2eaa74d253f50f58 isn't working something to worry about?

[o_e_l_e_o]

Yeah, looks like we managed to clear about 9 MB of 1 sat/vbyte transactions, from around 33 MB to down to 24 MB, before the mempool started filling up again. With the ongoing price ridiculousness (just breached $28k!), looks like the mempool is starting to fill again. I suspect your transaction will drop before it is confirmed.

That link is working fine for me. What do you see when you click on it? I can also still see your transaction on a number of other block explorers, so it doesn't look like it's been dropped from any mempools yet.

No. It's 9 days old and other block explorers see it.
I've found it on chainflyer.bitflyer.jp and sochain.com
Also whoever wants can easily re-broadcast it.

Actually I've just re-checked and possibly that has already happened. First I didn't see the tx on blockchair and now it works.

[TallblokeUK]

Just an "oops" we couldn't find what you were looking for link.

I think it's time I do something about this transaction.

I hate a look at RBF in bitcoin core but as this transaction leaves my wallet empty it wont let me do that.

The abandon transaction option is greyed out as well.

So any advice on what to do and how to do it would be great!

[o_e_l_e_o]

You won't be able to use a standard RBF unless you have additional funds in your wallet you can use to bump the fee, and the abandon transaction button won't work until the transaction is dropped from the mempool. You have three options going forward.

1 - Transfer additional bitcoin in to your wallet so you can use a standard RBF.
2 - Wait for the transaction to drop from the mempool, abandon it, and then create a new one.
3 - Start Bitcoin Core using the option -zapwallettxes to remove the transaction, then create a new one spending all the same inputs, but with a smaller output and a higher fee. I would back up your wallet file before doing this.

[TallblokeUK]

Could you give me a bit more info on the third option please?

When you say smaller output you mean smaller because of the higher fees?
-zapwallettxes looks like a startup line parameter, will I need to resync bitcoin core after doing that?

Don't want to screw it up, but like to sort this!

If you are not in a hurry, keep waiting. Sooner or later will be either confirmed, either dropped.
With some luck the activity won't be so high these days.

Edit: o_e_l_e_o is right, because it's sent to Coinbase part CFNP does not apply, hence I've deleted that part of the post in order to not cause unnecessary confusion.

[o_e_l_e_o]

I'd add one more:
1.1 - Try CPFP (child pays for parent), with much higher fee.

He said he was sending to Coinbase. If he means the exchange then CPFP is not an option. I've never used the Coinbase wallet, but I'd be surprised if it allows spending unconfirmed funds. CMIIW, though.

When you say smaller output you mean smaller because of the higher fees?

Yes. Since you are sending the entire contents of your wallet to another address, if you are going to replace that transaction using the same amount of bitcoin but using more of that bitcoin to pay a higher fee, then the final amount being sent to your Coinbase address will have to be smaller to compensate.

-zapwallettxes looks like a startup line parameter, will I need to resync bitcoin core after doing that?

Yes. -zapwallettxes will delete all transaction data, and will then need to rescan the blockchain to update all your addresses and balances again. It will also delete but not restore your unconfirmed transaction, which will allow you to create a new transaction spending these inputs with a higher fee, which when broadcast, will replace your current unconfirmed transaction since it is flagged as opted in to RBF.

Don't want to screw it up, but like to sort this!

Hence why you should back up your wallet file first.

Alternative: export your private key, import it into Electrum, and make the transaction from there.

I forgot all your outputs are on the same address, in which case this suggestion from LoyceV might be easier if you are familiar with Electrum.

-zapwallettxes looks like a startup line parameter, will I need to resync bitcoin core after doing that?

Only if you have a pruned node. If you have a ~350 GB blockchain on your disk, you're fine (but it will take a while).
Alternative: export your private key, import it into Electrum, and make the transaction from there. Electrum also allows you to manually control which inputs to use (Addresses tab, hold CTRL to select, use right-mouse to Spend from).

Think of it this way: the value went up a lot since you created this topic

[TallblokeUK]

I tried to sweep into Electrum but it is saying "no inputs" is that because my balance in Bitcoin Core is zero?

[LoyceV]

I tried to sweep into Electrum

Try import (create a new wallet, select "Import Bitcoin ~ private keys".

[TallblokeUK]

Aha!

That worked, sorry to be annoying, but what should I do next....

It's showing the unconfirmed transaction at the top and my balance as 0

Right click the unconfirmed transaction and select Bump Fee. You should be able to see a dialog to see the fees for the replacement transaction. If you do this, the transaction will be replaced with a similar transaction with a lower output amount and a higher fee.

Got it, so what's a realistic fee to get this thing confirmed today (with luck) but not spend a fortune

See Johoe's Bitcoin Mempool Stats: if you're lucky, 3 sat/byte is more than enough. If you're not lucky, 12 sat/byte should be enough:
My suggestion: make 2 transactions: use a low fee on the small inputs, and a higher fee on the larger inputs.

[TallblokeUK]

I think I'll try with 6.

So when I set that and click "ok" I get a confirmation screen

Transaction ID is unknown
And options along the bottom are Export / Save / Combine / Sign / Broadcast and Close

BUT broadcast is greyed out.
