Self-Custody Part 2: The Multi-Vendor Multi-Sig Masterclass
Part 1 was about understanding the vulnerabilities. Part 2 is about building the ultimate defense.
If the recent hardware wallet news taught us anything, it’s that relying on a single manufacturer is a single point of failure. The solution? Multi-vendor multi-signature (multi-sig) setups.
Join Bitcoin Bay Research as we break down how to combine hardware wallets from different manufacturers (think ColdCard + BitBox02 + Trezor) into one bulletproof, sovereign setup. Whether you attended Part 1 or are just now getting serious about self-custody, this is your blueprint.
What We’ll Cover:
🧠 The Fundamentals: What multi-vendor multi-sig actually is, and why it’s the gold standard for Bitcoin security.
⚖️ The Real Talk (Pros & Cons): Maximum security and no single point of failure vs. higher complexity, cost, and the learning curve. 🛠️ The Tech Stack: Exactly what you need to go from theory to practice. We’ll cover hardware requirements, coordinator software (like Sparrow or Specter), and how to safely manage your backups.
💻 Live Walkthrough: A high-level demo of how a Partially Signed Bitcoin Transaction (PSBT) actually moves through different devices.
The Vibe:
60-minute deep-dive presentation + open Q&A + networking. Bring your hardware wallets, your skepticism, and your appetite. Snacks, and drinks are proudly sponsored by the legends at Chobats VAR.
