If it's your own multisig, Sparrow and Nunchuk are my fav.
If it's assisted multisig, your no KYC option is Nunchuk, while I believe Unchained requires your personal info but works very well. I'm not personally a fan of Casa but that may just be my preference.
What do you think of using BIP85 to create 3 keys then using that in nunchuck for MultiSig?
Nunchuck keeps the master pub then Blue wallet on 3 devices each with one private key for a technically hot but way more secure MultiSig?
Not heard of anyone doing this but seems legit.
Also love sparrow and nunchuk. 2 off 3 multi, which hardware wallets do you prefer to set that up?
