The sparrow wallet is really good i looked into it and im still trying to connect it back to my node. Although you have specified the use of external signers directly with Bitcoin Core which actually is more of what i was looking for so ill have to see what's up with that. I think that if i manage to set up it up ill just use the bitcoin core as a cold wallet since its encrypted and anybody that would want to do any transaction would need the Trezor, right?

I do really like the sparrow wallet though so if the external signer works on my bitcoin core ill keep some holding in there and some holdings inside of my sparrow wallets that is connected back to my node.
Im not trying to keep all of my coins in one wallet if that makes any sense and i dont have any trouble making new wallets its just i wanted to make sure all wallets had a Hardwallet and that i owned my nodes.


Anyways sorry to confuse you in any sort lol
