Re: Not reading psbt file

I think I've figured it out. It's either that the transaction can be a max of 20 inputs, or the size of the transaction cannot exceed more than 384k bytes. The size of the transaction was the issue, not the number of inputs.

This presents a problem in that in order to get all of my remaining bitcoin out of my wallet, I'd have to do about 10 transactions. Is there no way around this?

No there's no error message. I'm able to do everything fine on electrum. I export the file to my microsd card to then sign it on my coldcard, but the coldcard simply does not read it. No error message appears on the coldcard too. It simply gives you the default screen when you select 'ready to sign' stating it is ready to sign transactions. But it doesn't pick up the transaction I saved on my micro sd card.

I've been able to send 90% of my bitcoin out of this wallet by keeping the inputs below 20 as per the helpful guidance in this thread.

But for some reason I cannot send the last remaining bit of bitcoin, and this is despite me keeping the inputs to 15, as stated on the transaction window in electrum. Would anyone know why? I'm not sure what has to be done differently. It says 'Inputs (15)'.

Good afternoon,

 I need to move my bitcoin out of this wallet. I could not figure out how to move it at the time of starting this thread, despite thinking I was following the helpful guidance here.

I created a psbt fille on electrum to sign on my coldcard. The electrum interface said Inputs (15) - Coin selection active (15 UTXOs selected)'

But my coldcard did not pick up on the psbt file again. I thought if i keep it to less than 20 inputs, this should work.

Is there any other method I can try? I do really regret using electrum now as it just is not user friendly at all.

This is really debilitating, as even one with five inputs isn't recognised but two inputs is. Is this something to do with electrum's software?

Yes I'm choosing inputs from the coins tab. And I just did two transactions, one with three inputs and one with two, and now it is not reading the one with three but it is reading the one with two! It's getting less and less!

Would you know why it works with 3 inputs but not with eight for example? My understanding was that anything less than twenty is fine? The small amount of bitcoin in each input means I would have to consolidate multiple batches of three inputs into one, so I end up with six (consolidating eighteen inputs) or so inputs, which I'd then be able to send as two inputs.

Is there an easier fix im missing?

Thanks all, would it also help from a financing perspective i.e. Getting a loan backed by the miners?

You've all been very helpful, much appreciated. I think I've made some progress via the above advice.

I managed to consolidate 5 inputs then send to where I wanted. But a problem I faced was that I originally wanted to consolidate more than 5 (15 or so) but every time I tried, the PSBT file wasn't read by the coldcard until I reduced it to 5 inputs. I've now also tried another consolidation to send more, and this time it didn't even read the 5 inputs but when I reduced it to 3, it's now worked.

OK yes the coldcard has recognised the transaction at less than 20 inputs, but it would require 6-8 transactions for me to send the total to where I want to. So am I able to open the psbt and delete certain things to reduce the input?
Is there a problem with consolidating the inputs first? Using a few transactions with less than 20 inputs to send back to your own address, and sending the consolidated inputs to your destination.

Deleting the inputs would result in your having less inputs for your transaction, and you need to include them all or else your total amount would be less than you desire.

To be honest I'm not quite clear on what that practically means.

So do you mean that I open electrum, generate my receive address, then go to the send window and send multiple transactions to my own address? How would sending bitcoin to my own address reduce the inputs.

I know it's probably super simple, just never done it before so I can't visualise and and not sure how consolidating works!

I'm not sure what's meant by using a segwir signature and providing only the individual UTXO?
That is for the PSBT file. PSBT files includes loads of redundant data and stripping it down helps to reduce the size restricted by the communication bridge.

Thank you. To get the input to 20 or less, I can't send more than 0.02 bitcoin at a time. There surely must be a simple way to change this? ​Any bitcoin amount that is 0.03 or more is 21 inputs. I've sent more than this a month ago so I'm unsure what's changed.
Try if it'll sign with <20 inputs first. Use Coin control if needed on Electrum. I think fees are fairly low right now; would it be possible for you to send two transactions back to an address in your wallet (1x 12 inputs, 1x 13 inputs) and spend it with ColdCard, the two created inputs from the two transactions?

Does it have anything to do with the number of inputs and outputs on the transaction window at all? It says 25 inputs and 1 output. Probably irrelevant, but I don't know what else to focus on. Like I said, this happened last month to me, and I simply updated my version of  electrum, after which the coldcard read the psbt file.
Eh, that's actually the issue.

Coldcard supports 20 inputs to be signed at once[1], presumably due to the fact that it is unable to sign so many due to hardware limitations. I've never encountered this issue, only because I've never had to sign that many inputs but I think that the limitation still applies right now. Since it's mainly a hardware limitation, there isn't anything else that you can do other than to split the transaction up smaller.

It works for me, Electrum 4.1.4 and ColdCard 4.1.1.

Is your ColdCard on the correct file format? Assuming that you do not hold anything sensitive on your SD card, you can try formatting it. Do backup anything you want on the SD card first. Afterwhich, go to Advance>MicroSD Card>Format Card. This will remove everything from your SD card and use the correct file system.

I formatted the card and created a new skeleton wallet as well and still the coldcard doesn't read the psbt file on the microsd card.

Now it seems nothing works. Coldcard version is 4.1.1 and electrum is 4.1.4.

When I go to sign on my coldcard it simply states that it is ready to sign transactions, it doesn't read the files on the microsd card.

Is there any benefit to setting up a limited company and mining as such rather than mining personally?

This time, I don't know what the problem is, as I have the latest version of both electrum and coldcard. Does anybody have experience with this?
Did you update either Electrum or the coldcard firmware since you last attempted to send a transaction and/or had the same issue? Huh If so, it's possible that one of them has introduced an issue...

Not sure if you can downgrade the Coldcard... but using an older version of Electrum is relatively easy (you can grab one of the portable versions if you're using Windows and use it temporarily until you resolve the problem). The only issue you may run into is if the Electrum wallet file version has been "upgraded", then a lower version of Electrum will likely refuse to open it... and you'll have to re-import the watching only wallet into Electrum.

I can't apparently send bitcoin from a watch only wallet? Sorry if I'm being slow, I'm trying to find out what exactly is wrong and hopefully send bitcoin today.

Hey,

No, since my last successful transaction last month, nothing changed. So I don't know where the issues lies.

So earlier today j downloaded the older version of electrum 4.1.1, but now it says it's too old of a version to load my wallet as you mentioned. I use an apple so I'm hoping there's a simple workaround.

My coldcard isn't reading the psbt file on the microsd card.

It did this a month ago, and I then updated electrum to the latest version after which it recognised it and I was able to sign the file on my coldcard.

This time, I don't know what the problem is, as I have the latest version of both electrum and coldcard. Does anybody have experience with this?
