Coldcard Was Supposed to Be the Safest. What Now?

Connect with Early Riders — https://www.earlyriders.com/contactConnect with Onramp — https://onrampbitcoin.com/contact-us/Presented collaboratively by Early Riders & Onramp Media…Final Settlement is a weekly podcast covering capital markets, dealmaking, early-stage venture, bitcoin applications and protocol development.The Coldcard exploit has escalated: nearly 2,000 Bitcoin drained and counting, passphrase wallets confirmed compromised, MK4s and Qs exposed alongside the deprecated MK3, and Coinkite confirming a five-year-old flaw in on-device seed generation. This week Michael, Liam, and Brian walk the full timeline of the worst self-custody incident in Bitcoin's history: how the RNG silently downgraded to guessable entropy, why same-vendor multisig quorums are also at risk, and the firmware updates reportedly bricking devices mid-migration. Michael and Liam share their own weekend fund migrations (one from the back seat of a car), and the guys get into the harder questions: why AI may be a bigger threat to Bitcoin security than quantum computing, why the stampede to exchanges and ETFs is the wrong lesson, and what a fault-tolerant custody architecture looks like when one mistake can no longer be allowed to knock you out of the game.Chapters00:00 - The Coldcard exploit: what happened and who is affected02:20 - Move your funds: urgent guidance for Coldcard holders05:09 - Technical breakdown: how the RNG flaw was exploited10:17 - Passphrases, firmware bricking, and the silent downgrade17:14 - Earlier warnings and why same-vendor multisig is exposed21:22 - Weekend migrations: Michael and Liam's personal anecdotes30:26 - AI vs quantum: the real threat to Bitcoin security33:25 - Single-vendor risk, single-entity risk, and custody honeypots44:03 - Silver linings: the end of the custody purity test50:26 - Where the industry goes from here56:15 - One mistake can't knock you out of the game59:05 - Final guidance and staying vigilantIf you found this valuable, please subscribe to Early Riders Insights for access to the best content in the ecosystem weekly: https://www.earlyriders.com/researchKeep up with Michael:https://x.com/MTangumaKeep up with Liam:https://x.com/Lnelson_21Keep up with Brian:https://x.com/BackslashBTC
