#120 AI, Bitcoin Security & Self-Custody: How Casa Protects Your Wealth | Paul Brower

In this episode of The Crypto Podcast, Roy sits down with Paul Brower, Director of Engineering at Casa — the gold standard in Bitcoin self-custody — where he leads a 12-person team building AI-first workflows to protect billions of dollars in Bitcoin. Before Casa, Paul spent seven years building the first FDA-approved digital pill software, was an early Bitcoin adopter since 2011 (including a Mt. Gox close call), and even spent three episodes on an MTV reality dating show. Paul breaks down how Casa's multi-sig self-custody system works (2-of-3, 3-of-5), how attackers are now using AI-powered spearphishing and deepfakes to impersonate support staff, and how cryptographic PIN verification protects users from social engineering. He also covers key loss prevention (health checks, hardware redundancy, YubiKeys vs. Trezor/Ledger), Casa's inheritance system for passing on Bitcoin securely, the risks of giving AI agents access to financial accounts, and why physical air-gapped hardware remains one of the strongest defenses against an increasingly AI-powered threat landscape.
