The hardware wallet was supposed to be the safest place to hold Bitcoin. Offline. Air-gapped. Away from internet-connected systems. The gold standard of self-custody. This morning, Coinkite disclosed that a build error meant seeds on Coldcard hardware wallets were drawn from a software fallback instead of the hardware generator. The firm believes an attacker used AI to find a flaw its own AI review weeks earlier had missed. 594 Bitcoin swept from 500 wallets in under 30 minutes. Many of those wallets had been dormant for years. The holders were not careless. They did exactly what the industry told them to do. They took their Bitcoin offline. They held their own keys. They trusted the hardware. The hardware failed them at the generation layer. Before the Bitcoin was ever stored. Before any transaction was ever signed. The seed was weak from the moment it was created. A seed created on an affected Coldcard stays weak even after being restored to another brand’s device. This is why single points of trust are always a risk. Not because the hardware is untrustworthy. Because any single layer, however well designed, can fail in ways nobody anticipated. Distributed key infrastructure is not a luxury. It is the only architecture that survives a failure at any single layer. #Bitcoin #SelfCustody #CryptoSecurity #Inheriti #DigitalAssets
