Hello everyone,
I am currently tinkering around with small fund amounts to learn how to use Multisig and I came across something weird that I cannot quite figure out myself.
In short, I set up a multisig 2 of 3 on Sparrow that was 1 software wallet (seedwords directly into the local machine) + 2 other hardware wallets.

I didn't quite like it that Sparrow would not let me lowball the fees as much as I wanted so I decided to export this Multisig wallet to a format compatible with Electrum wallet.
When I got to signing the transaction as I wanted it to, I ended up being asked to only provide signing by one of the hardware wallets (I supposed the seedphrase from the local software wallet also got expored).
Here is the part that worries me:
On Electrum if I go to Wallet > Private Keys > Export and I happen to want to open that, it will actually open a list of the miltisig address tree together with what appear to be secret keys (P2WSH type), without even asking me for a hardware wallet or it even being connected to the local machine, just the local software wallet seems to be enough.

Now maybe I am missing something here, even the Electrum software itself tells me in a warning message:
"WARNING: This is a multi-signature wallet.
It cannot be "backed up" by simply exporting these private keys."

I just got spooked it still does display some private keys. So are these keys legit or just some private keys needed in part of the software seed to make the whole scheme work?
My initial impression was they were somehow the actually private elements of the corresponding Multisig addresses listed on this wallet.
Just wanted to hear your thoughts on this. I might be just worried for nothing seeing this stuff (since my expectations were: no access to hardware wallets, no showing private keys)

Hello everyone,
I just got myself some hardware devices from different companies in an attempt to reduce that risk surface of "one entity/company pulling a exit scam". Of course, kind of unlikely, but why not learn Multisig to mitigate this risk (helps with software/code vulnerabilities too).
Anyway, here is my question:

I want to set up 2 of 3 multisig. I noticed those 3 elements are initially needed to set up/create this scheme.
What happens if somehow I totally lose access to one of these seedphrases/elements, zpub included (even the common one).
Let's say I somehow end up in a situation where I will have access to only two seedphrases, are these enough to create a 2 of 2 multisig that has similar properties or will that 3rd element still be needed?

In the classic setup with single signature seed backup, the seed itself is enough to derive the list of addresses and the rest.
Are 2 out of 3 seeds enough to generate that same address tree if I try to use them to make a 2 out of 2 setup? I noticed all devices seem to go for this derivation path: m/48'/0'/0'/2'

I hope the question was clear enough  , the reason I got this curiosity now is because of backup procedures.
I am now left wondering if I should worry only about the seeds primarily or also if I must seek to make backups of the respective xpub/zpub information for these respective seeds to rebuilt at a later date.

Thanks for your time, I hope some of you can help me out here.

Hello everyone.
In case this was asked before I hope some of you can guide me.
So I am trying to set up a full node too, but on an older machine. But the laptop itself is not that bad. Intel CPU is 2.00 GHz x 8, 4 GB Ram.
I set it up with a 2TB HDD so that it can house the blockchain.

I am running the core client on Ubuntu 22.04.1 LTS, and I just don't know where to start in finding out why it just runs for a couple minutes, then suddenly vanishes/crashes.
This is with the GUI client. I have not yet tried out the CLI version only.
I tried to reduce in the settings the DBcache to 300 MB, but still seems to do this.
What is the process one can follow in an attempt to find out why the client just decides to close itself out of the blue?
Thanks a lot in advance.

Hey guys,
I'll keep it short. I buy bitcoin via online exchanges and then also always withdraw to personal wallets.
As I am listening to discussions about how this FTX mess will evolve, I see some folk saying how the US has some Clawback laws in terms of bankruptcy which are there to protect credits that were not paid back.
So now my obvious questions/doubts are:
"Wait a second, so I could start seeing in the future letters from lawfirms or such saying I gotta give back the money I withdrew so that other people that lost money get some back?"
I mean for the creditors it would make sense, and defintely piss off people like me that just use these exchanges as means to get what I want.

But if this were true, then I would ask myself: what is the point of ever touching exchanges and even having those withdraw buttons there if any exchange that goes belly up could get enforced by the US to have funds be called back? (I suppose allied countries will usually assist US actions, to have nice relationships with them. And cuz of KYC they know who you are and put some legal pressure on you).

But yeah, you get the idea.
So could it be that in the future I will be told to give money back because I happened to use FTX?

Thanks for you time!

Hello everyone,
There is a question that often came to my mind but I never much asked around, so I'm hoping some of you can give me feedback/opinion.
I was wondering what the security trade-offs are between 12 word vs 24 seed words are? I personally like using 12 seed words since you can also memorize them yourself more easily, but I was wondering if the less entropy/randomness of such a seed would be a problem vs the 24 variant?
I see that wallets still offer support for 12 word seed, even some of them let you generate them (making me think they are still very secure to this day).

So in essence my question would be:
Am I doing something horribly wrong by using 12 word seeds and not the 24 word one, not realising risks I could be exposing myself to? (I will add that I do use a password on top of these words as well)

Thanks for your time, hope to get some insights from you all.
