Section 2

Role Separation

Wallet Role Architecture

Mark which dedicated wallets you maintain (aim for 3-4 separated roles):

Signer Diversity & Rotation

🚨 Low diversity. Multi-sig may provide false sense of security.

Section 3

Incident Response

IR Readiness Checklist

🚨 Not prepared for incidents. Lack of preparation amplifies damage.

Tabletop Exercise

🚨 Scenario: Private Key Compromise

It's 2 AM. Your monitoring bot alerts: deployer wallet submitted unexpected ownership transfer to unknown address.

Q1: What's your FIRST action?

Q2: Contract paused. What's next?

Watch Out

Common Mistakes

💻
I use the same MacBook for personal browsing and treasury signing — it's more convenient
One compromised website or extension and your treasury is exposed. Dedicated signing devices are non-negotiable.
👑
Our admin is a single-key EOA because multi-sig is slow
Speed is worthless if one compromised key drains everything. Multi-sig with time-locks is the standard.
🏢
Our 3-of-5 multi-sig has all keys in the same office
Same location defeats multi-sig purpose. Diversify brands AND locations.

⚡ Golden Rule: At the power-user level, security is a process, not a feature. It is something you practice, audit, and improve continuously.
