Maxtxfee - Servers problem.

[bitstonps]

Hello

I've been struggling with an issue all day and need some assistance.

I transferred funds from Coinbase to my account, but noticed Coinbase uses several unconfirmed hashes (Parent) for the transaction. Receiving this through Electrum, I attempted a CPFP (Child Pays for Parent) but the transaction fee was too low for its large size, about 85 KvB.

When trying to increase the fee in the new hash (setting it to 20,000 sats for 110 vBytes), I encountered an error upon signing and broadcasting: 'The server returned an error when broadcasting the transaction. Consider trying another server or update Electrum. Fees exceed maximum configured by user.'

I was able to set 10,000 sat

Even attempting to sign the transaction and broadcast it manually on different servers resulted in the same error: 'Code: -25 Error: Fees exceed maximum configured by user' (referring to settings like -Maxtxfee, Maxfeerate).

Can anyone provide a solution to this? Your help would be greatly appreciated.

Regards,

The server doesn't allow you to broadcast the transaction because the fee is too high.
I think you wanted to pay 20,000 sat as transaction fee, but you mistakenly set the fee rate to 20,000 sat/vbyte. If that's the case, you were lucky that the server didn't broadcast your transaction.

I'm Lucky that the server didn't proceed ?! Who said that I have already set 10k sat. and I want to increase it to 20k sats.
Please read the post again before jumping,

Thanks.

If the total transaction tree is 85,000 vbytes, adding 20k sats CPFP only adds less than 0.25vbytes/sat. That's less than 1% of the current minimum fee.

When trying to increase the fee in the new hash (setting it to 20,000 sats for 110 vBytes)

It may be 110 sat/vbyte for your transaction, but if you want it for the 85,000 vbytes, you'll need to pay 0.093BTC in fees. In short: there's no point using CPFP for a transaction with that many unconfirmed parents. Complain to Coinbase, or wait for fees to drop (and nobody can tell you if that's going to happen any time soon).

Please read the post again before jumping,

I read your post and I just explained what the error message tells us.

Fees exceed maximum configured by user (referring to settings like -Maxtxfee, Maxfeerate)

The error message is clear.
According to the message, the node didn't broadcast your transaction because the fee rate you used for your transaction was higher than Maxfeerate or the total fee was higher than Maxtxfee.

When trying to increase the fee in the new hash (setting it to 20,000 sats for 110 vBytes), I encountered an error upon signing and broadcasting

hosseinimr93 is correct. 20,000 sats for 110 vbytes is 181 sats/vbyte. Both of these values are far below the DEFAULT_TRANSACTION_MAXFEE and HIGH_TX_FEE_PER_KB settings in Bitcoin Core (which are 0.1 BTC or 1,000 sats/vbyte, respectively).

If you are getting the same error on multiple servers, then the problem is with your transaction. I also suspect you have maybe set the fee to 20,000 sats/vbyte rather than 20,000 sats overall (which as LoyceV has pointed out, will achieve nothing anyway).

Thank you all for the answers,

This is a screenshot so you can have a clear vision about the situation : (https://prnt.sc/d6kR-NANxQM1)

The wallet used is Electrum.

So, you made a CPFP transaction with the fee rate of 10,046 sat/vbyte and the total fee of 0.011 BTC.
Now, you want to bump the fee rate of this transaction to 20,000 sat/vbyte.


Since you say you tried different electrum servers and none of them allowed you to broadcast the replacement transaction, one solution is to export the raw transaction, broadcast it using other tools and see if they allow you to do so.

Here are some broadcasting tools.

• coinb.in
• ViaBTC
• blockstream

The other solution is that you make a new CPFP transaction instead of bumping the fee of the previous one. Note that in this way, you will add another unconfirmed transaction to your wallet.
To do so, you need to make the new CPFP transaction manually with spending the fund from bc1qkxy......... to one of your own addresses.
If you make this transaction with the fee rate of 10,000 sat/vbyte, it would have the same effect as bumping the fee rate of your CPFP transaction to 20,000 sat/vbyte and it would increase the effective fee rate of your transaction to 35.5 sat/vbyte which is still insufficient for getting fast confirmation.

Take note that you have already spent $480 worth of bitcoin for doing CPFP and you will spend another $480 worth of bitcoin for making another CPFP transaction or increasing the fee rate of your current CPFP transaction.
Also note that you may need to use coin control, if you have other funds in your wallet and you want to make a new CPFP transaction manually.

Hi,

I appreciate the time you took to write this.

We need that funds for urgent project and yes we want to sped another 480$ on fee.

We have already performed the CPFP inside electrum and it doesn't give us the option to create another child transaction only to increase fee which seems impossible to do it above 10k sats

We have Confirmed coins inside the wallet and we have a doubt that this may Affect other coins, and block the entire wallet.

We have tried to to use the Hex after signing the transaction and all these websites return the message code 25 Maxtxfee.

Thank you again for the response.

As I said in my previous post, even if you bump the fee of your CPFP transaction to 20,000 sat/vbyte and spend another $480 worth of bitcoin, you would increase the effective fee rate to 35.5 sat/vbyte and that's still insufficient for getting fast confirmation.
Of course, that will surely help you get confirmation faster.

That wouldn't change anything.
For doing CPFP you should spend the fund received in the unconfirmed transaction.

We have already performed the CPFP inside electrum and it doesn't give us the option to create another child transaction only to increase fee which seems impossible to do it above 10k sats

There is no CPFP option in right-click menu for a transaction that has been made for doing CPFP itself and that's why I suggested making another CPFP transaction manually.

In your CPFP transaction, you sent the unconfirmed output from bc1q4stj....... to bc1qkxy......
Now you should spend the same fund from bc1qkxy..... to another address with high fee.


To make the CPFP transaction manually:

• Copy a bitcoin address to your clipboard.
  Take note that this address will receive the unconfirmed coins. So it should be your own address.
  
  
• Go to "Coins" tab.
  If you don't see "Coins" tab, click on "View" at top of the window and check "Coins".
  
  
• Find the coin you received in the CPFP transaction, right click on it, select "Fully spend" and then "send to address in clipboard".
  Note that the coin you should select is worth 0.558xxxxx BTC.
  
  
• Enter the desired fee rate and make the transaction.
  As I already said, if you make the transaction with the fee rate of 10,000 sat/vbyte, it would have the same effect as bumping the fee rate of your CPFP transaction to 20,000 sat/vbyte.

In this way, you will increase the effective fee rate of your transaction to 35.5 sat/vbyte and if you want to increase it more, you should make the third CPFP transaction.
At the time I am writing this post, around 40 sat/vbyte is required for getting fast confirmation.

Don't worry about this. The unconfirmed transaction can't and won't prevent you from spending your confirmed coins. Otherwise, this would be a serious flaw in bitcoin!
To spend your confirmed coins (utxo), you can either use the coin control feature to select which coins you want to spend or deactivate the option to spend unconfirmed coins.

Coinbase uses several unconfirmed hashes (Parent) for the transaction

Complain to Coinbase. They know better. They've been scolded for doing this in the past (paying customers with unconfirmed bitcoins) when they first started as a company and they supposedly fixed their software to not do that. They need to fix this quickly or they are risking serious damage to their reputation as a trustworthy exchange.

I want to send you a message and I got this message : You have exceeded the limit of 2 personal messages per day

I just want to thank you for the last message, You are a real legend , thank you so much Merit ++

I just want to thank you for the last message, You are a real legend , thank you so much Merit ++

You are welcome.

I just checked your address and I see you have made two other transactions and the effective fee rate is now 42.1 sat/vbyte.
Unfortunately, the network has become more congested in the past hours and your transactions are still unconfirmed.

If you are a bit lucky, your transactions will be confirmed in the next few hours.
