Question about multisig, electrum + trezor/coldcard etc
Hi, from the video, I understand Sun created a multisig wallet using electrum and then use the 2 trezor for a total of 3 keys. You will need at least two keys to sign a transaction and he showed it while making a transaction using electrum and then using one of the trezor.
He then created an address in the multisig electrum wallet to send himself some BTC and show how to send it out co-signing it with one of the trezors.
How does the electrum generate a UTXO that require multi signature using only 1 pirate key? Can I see that UTXO if I login to either of my trezors?
In my small brain I think that if the UTXO is generated on electrum i shouldnt be able to see it in my Trezor, but if that is the case what happens if the 2 keys i have out of the 3 is the two trezors?

the trezor (or any other HW wallet for that matter) does not really know anything about your wallet, including UTXOs – all it “knows” is its own private keys and all it can do is sign the data it is being fed with its own private keys. All the logic happens on the “online” wallet’s side, be that electrum, sparrow, bluewallet or anything else – they will keep track of utxos, create the transaction, and serialize it in a way your hw wallet can understand for signing.
