Coldcard Makes User Entropy Mandatory for New Seeds

Coinkite’s current standard firmware—5.6.1 for Mk4/Mk5 and 1.5.1Q for Q—requires each newly generated standard seed to add at least 65 unpredictable key presses, 50 physical die rolls or 128 physical coin flips to device entropy. The company says installing the update does not repair an existing affected seed: users must generate a new seed and move every funded balance unless the advisory’s exact private 50-roll exception applies. Coinkite says its independent checks were targeted, not a complete audit, and a formal postmortem is still in progress.
