Odaily News: Galaxy's Head of Research posted on Platform X stating that all Coldcard single-signature settings that were not set up using dice rolls, do not have a passphrase configured, and use firmware from March 17, 2021 or later will be cleared. Unless users import a high-entropy seed from another source or use multiple dice rolls, it is recommended to completely stop using Coldcard.
