Coldcard Hack: Lessons learned and How to Avoid the Next Exploit

​Learn how the Coldcard hack happened, how onchain tracing enables white hat hackers to see what's going on, and what the Bitcoin Red Team is doing to protect everyone else. A reminder to protect yourself against the latest physical and digital threats using multi-signature and multi-vendor crypto wallets. A crash course in self-custody for 2026.

​The CVA Cybersecurity Working Group continues its monthly series with a session dissecting a real-world hardware wallet exploit — what went wrong, what it exposed about single-vendor custody setups, and the practical steps individuals and institutions can take to avoid repeating it. Expect a grounded, technical walkthrough rather than theory: multisig design choices, vendor diversification, and the operational habits that separate resilient self-custody from a false sense of security.
