Coinkite, the maker of the Coldcard Bitcoin hardware wallet, released new standard firmware on Aug. 20 that forces users to add physical randomness whenever they generate a seed.
Key facts
- Coldcard's current security status recommends version 5.6.1 for Mk4 and Mk5 devices and 1.5.1Q for Q devices
- Bitcoin is +0.57% over the past 24 hours and currently sits at rank # 1 by market cap
- During standard seed creation, every seed combines fresh device entropy with one required human input source: at least 65 key presses made at unpredictable intervals, 50 rolls of a physical six-sided
- Coinkite's official migration guidance covers Mk2 and Mk3 firmware 4.0.1 through 4.1.9; Mk4 and Mk5 standard firmware before 5.6.0 and Edge firmware before 6.6.0X; and Q standard firmware
Summary
01 Coldcard now requires 65 key presses, 50 die rolls, or 128 coin flips for new seeds. 02 Seeds created on affected firmware may remain exposed; installing a fix cannot repair them. 03 Affected users should create a new seed and migrate funds unless they meet the private 50-roll exception. Owners who generate a seed after installing the current fixed release can use the hardened process.
