ColdCard Hack Deep Dive: Is Your Self-Custody Actually Safe?

Hey Bitcoin Bay Community! 🍁

Canada’s longest-running crypto community is hosting a special, high-priority meetup to address the recent ColdCard hardware wallet vulnerability.

The Context: On July 30th, a critical flaw was exposed in the Random Number Generator (RNG) and entropy collection of certain ColdCard devices during initial wallet generation. This allowed bad actors to mathematically predict seed phrases and drain wallets without the owner’s knowledge. No passwords stolen. No computers breached.

What We’ll Cover:

• The Autopsy: A technical (but accessible) breakdown of the RNG failure.
• Triage: Step-by-step guidance on checking your specific device/seed for risk.
• The Narrative: What this means for "Not Your Keys, Not Your Coins" and the broader self-custody landscape.
• Upgrades: Exploring better entropy sources and advanced setups (like multi-sig).

The Format:

• 6:00 PM – 6:30 PM: Doors open, grab food & drinks, and network
• 6:30 PM – 7:30 PM: Presentation by Bitcoin Bay Research + Live Q&A
• 7:30 PM – 8:00 PM: Open networking, debate, and compare self-custody setups

Food & Drinks:
Snacks and beverages are on us, generously sponsored by Chobits VAR! Come hungry and leave educated.

The Details:
📅 Date: Monday, August 10, 2026
⏰ Time: 6:00 PM – 8:00 PM ET
