I will post a blog article later today. But TLDR:
- it's worse than you think.
- Mk4, MK5, Q will get drained.
- multisig of Coldcard devices, or multisig where Coldcard signatures are sufficient to reach the threshold are at risk.
- MINISCRIPT WALLETS are ALSO at risk, if you use Coldcards where only CC signatures are enough to spend, or to recover.
No need to panic, but time to plan a move to new mnemonics/devices in the next few days, if you used a Coldcard in your setup.
