I want to use coldcard wallet + another device, possibly a smartphone, for multisignature. Ideally I'd like to use Coldcard + Bitpay.

I've found tutorials on coldcard multisig: https://www.youtube.com/watch?v=OMpZ5heLsRg but it involves multisig between coldcards only.

I think BitPay is very user friendly so it wouldn't let you use multisig from importing the pubkey of the coldcard.

What are my options?

  • How about coldcard with bluewallet? – Prayank Dec 27 '20 at 21:57
