Nunchuk responds to Coldcard vulnerability: platform keys will not be used directly
According to monitoring by Bitcoin News, Nunchuk stated that some keys on the Nunchuk platform are generated by Coldcard Mk4, but these keys will not be used directly.
Nunchuk will derive independent keys through custom logic, making them less susceptible to lookup table attacks based on leaked Coldcard seeds. Nunchuk added that, given enough time, it believes attackers may eventually incorporate these derived keys as well.
