Don't Trust. Verify. The Coldcard exploit isn’t just a vendor failure. It’s a community failure. The code was available, and everyone trusted the reputation, the marketing and the assurances—but too few of us actually verified. With AI-assisted auditing, nearly anyone can now examine open-source software and help find bugs like this. Instead everyone vibe coded new toys. Open source only protects us when we inspect it. It's a harsh lesson. Our hearts go out to everyone who has lost sats.
