Coldcard Rolls Out Security Updates After Multi-Million Dollar Exploit

Coinkite has issued a new firmware update for its Coldcard hardware devices following a comprehensive three-week security evaluation. The patch resolves several security concerns that were discovered during the review period.

As part of the update, the wallet now mandates that users introduce their own external entropy when generating new recovery seed phrases. This requirement is intended to strengthen the randomness and integrity of private key creation.

The development follows a recent $130 million Bitcoin exploit that brought renewed attention to key generation mechanisms. For individuals practicing self-custody, maintaining updated firmware and ensuring robust key generation practices are critical steps in securing digital assets.
