Corporate Key Succession: Legal Protocols for Multi-Sig Signer Incapacitation
The Executive Verdict
1. The "Bus Factor" Audit: Quantifying Governance Risk
Audit your Bus Factor. Level 1 (Critical): Single Key. Level 2 (High): 2-of-2 (Deadlock Risk). Level 3 (Safe): 3-of-5 with geographic dispersion. Fiduciaries must be at Level 3.
2. Integrating Multi-Sig into the Operating Agreement
Update Bylaws to include: 1. Master Wallet Address (The Treasury). 2. Keyholder Mandate (Roles, not just people). 3. Rotation Trigger (Death/Incapacity definition).

3. The Role of the "Institutional Signer"
Entities don't die. Assign 1-2 keys to: A. Corporate Counsel (Law Firm held in vault). B. Institutional Custodian (e.g., Coinbase Prime). They act as the "Recovery Quorum."
4. Technical Fail-Safes: The "Dead Man's Switch"
Automation as a last resort. "Heartbeat" Transactions: Signers must check in every 90 days. If missed, the Smart Contract automatically rotates ownership to a backup entity/trust.
5. Powers of Attorney in the Age of Cryptography
Standard PoA is useless without the keys. Create a "Digital Asset PoA" that grants legal rights AND provides physical access instructions (Vault Location/PIN) to a specific Digital Executor.
6. Operational SOP: The Key Rotation Ceremony
1. Board Resolution (Remove A, Add B). 2. On-Chain Proposal (removeOwner/addOwner). 3. General Counsel Verification (Hash matching). 4. Archivist (Store Resolution + Hash).
Succession Checklist. Step 1: Legal Vote. Step 2: Key Gen. Step 3: Multi-Sig Execution. Step 4: Audit Log.
7. The "Anti-Hype" Governance Standard
Never share seed phrases. Redundancy means Adding Signers, not sharing passwords. Shared keys break the "Chain of Custody" for audits and theft investigations.
8. Summary Checklist: Fiduciary Immortality
1. Bus Factor > 2. 2. Bylaws Updated. 3. Institutional Signer Active. 4. Dead Man's Switch Live. 5. Annual Recovery Drill.
⚠️ The 2-of-2 Trap
F.A.Q // Logical Clarification
Can I put my seed phrase in my Will?
"NO. Wills are public. Put the location of the hardware device and instructions, never the key itself."
What if the Law Firm loses their key?
"In a 3-of-5, you use the other 4 keys to rotate them out. The system heals itself."
Is there insurance for Lost Keys?
"Rarely. Crime insurance covers theft. Incompetence is generally uninsurable. Protocols are your only insurance."
