I really want to give my friend a good answer to this, he is very worried. I was the one who suggested he use coldcard in a multisig so I feel I owe it to him to give him a thorough answer.
quotingA friend sent me this and I wasn’t sure how to respond:

“I have a 2/3 multisig with a coldcard and 2 devices from 2 other vendors. The coldcard also had funds in single sig (same seed as used in the multisig). The single sig funds were stolen already. How vulnerable are the multisig funds until I migrate to a more secure wallet?”
I asked and he said he had spent from the multisig wallet a few times to test the setup, and also to correct an accidental address reuse.
I’m not sure what to tell him, anyone have any advice?
