Coldcard, via its maker Coinkite, rolled out new firmware security measures following a reported $130 million Bitcoin exploit, according to Decrypt.

The update requires users to add their own randomness when generating wallet seeds, a change aimed at hardening the seed generation process against the type of issue that can undermine wallet security.

Coinkite also described fixing additional security problems that were uncovered during a three-week review of the device and its related security matters.

The measures come as part of the firmware release, with Coinkite positioning the update as a response to vulnerabilities identified after the exploit.
