Coinkite Sued After Coldcard Wallet Flaw Exposes $140M in Bitcoin

Coinkite is facing a lawsuit after a reported Coldcard wallet vulnerability exposed approximately $140 million in Bitcoin to potential theft. The claim raises questions about the device’s security and the company’s responsibility, though the reported exposure does not establish that funds were stolen. The case could increase scrutiny of hardware-wallet design, vulnerability disclosure, and manufacturers’ liability, underscoring that self-custody security depends on both software and device safeguards.
