LIVE 🔴 Bitcoin self custody in 2026: the COLDCARD hack, the Trezor data breach, and how to secure Bitcoin. Hardware wallet security, multisig, passphrases, entropy and on chain time locks, rebuilt from first principles.

Self custody just failed a stress test nobody was ready for. A COLDCARD firmware flaw produced weak seeds going back to 2021, and coins were swept from people who believed they held the safest hardware wallet made. Trezor customers had their names, home addresses and phone numbers leaked through a shipping partner, many of them people who had only just switched. A fake Sparrow wallet sat live in the App Store. A phishing ad ranked above Trezor's own search result. BitBox audited itself with AI and found critical bugs.

The old advice was buy a device, write down your words, you're safe. That advice is dead.

In this episode we rebuild Bitcoin self custody from first principles with two people who do this for a living: Tony, founder of The Bitcoin Way, and Doctor Francesco Madonna, CEO of BitVault. They agree on the diagnosis and they disagree, sharply, on the cure. Tony will not allow a third party anywhere near a setup. Francesco's design puts a co-signing key with a service and enforces spending delays on chain. We put that disagreement on the table instead of around it.

We also build the actual 2026 process, step by step: ordering a hardware wallet without your home address ending up in the next breach, generating and verifying entropy, passphrase structure, when single sig plus passphrase beats multisig, two of three across multiple vendors, on chain time delays, descriptor backups, and the recovery rehearsal almost nobody runs.
