When screens go dark, the worksheet still answers
Multi-signature cold storage spreads signing authority across people and locations. A single screen cannot show the full picture. Our worksheets compile address lists, derivation paths, expected balances, and signatory roles into bound records that survive power outages, travel restrictions, and deliberate air-gapping.
Each engagement is scoped to your threshold scheme—2-of-3 family vaults, 3-of-5 foundation treasuries, or bespoke arrangements negotiated with your counsel.

Client notes
What holders say after their first reconciliation
Our 3-of-5 board could finally agree on which xpubs belonged to which reserve bucket. The worksheet listed every derivation index we had ever used—something our prior spreadsheet never captured.— H.S., family office administrator, Seoul
The signing ceremony documentation was thorough, though I wish we had scheduled an extra hour for the custodian walkthrough. Still, the bound copies now sit in our vault beside the seed shards.— M.K., nonprofit treasurer, Busan
