Track cold reserves without opening a live feed
We sit with your offline wallet inventory and write a rebalance worksheet you can keep beside the devices — no always-on dashboard required.
A worksheet session, not another screen
Self-custody reserve positions drift when purchases, airdrops, and transfers accumulate across devices you rarely plug in.
Our flagship session maps what each offline wallet actually holds, then drafts a rebalance worksheet with target weights, move sizes, and a verification checklist you complete at home when the devices are powered.

Sessions we run from The Octagon
Each visit is appointment-based desk work for people who already hold reserves offline and want clearer paper records before they move coins.
Reserve rebalance worksheet
A focused desk session that turns your offline wallet balances into a written rebalance plan with move sizes and verification steps.
Cold-wallet inventory
First-pass mapping of every offline wallet, label, and balance note so future rebalance worksheets start from a clean baseline.
Custodial handoff review
Desk review when reserves move between cold devices or from a custodian into self-custody — worksheet focused on what changed and what still needs confirming.
What clients notice after the table clears
Notes from recent worksheet sessions — specific about the work, not generic praise.
We spent two hours lining up three hardware wallets against my handwritten inventory. The worksheet finally showed why my BTC share had crept past the band I set last year.
I still prefer doing the actual device transfers myself. What helped was the sequence on paper — which wallet first, what amount, and how to re-check balances without using a phone app at the desk.
