Your cold wallet register deserves the same rigour as your custody policy
Toolkit Aspen Way maintains offline wallet registers for family offices—reconciling hardware holdings, documenting multisig arrangements, and keeping succession-ready records current.
In brief
Written registers, not spreadsheets left on shared drives
We produce structured cold wallet registers that list device serials, derivation paths, cosigner roles, and recovery contingencies—formatted for board review and estate counsel.
Quarterly reconciliation against live holdings
Each engagement includes a physical verification pass: hardware wallets present, seed phrase custody locations confirmed, and discrepancies logged with remediation steps.
Successor-ready documentation
Registers are written so trustees and next-generation family members can understand custody arrangements without relying on a single key holder's memory.

Client notes
What principals say after a register cycle
Our prior register listed twelve devices but only nine were physically accounted for during Toolkit Aspen Way's first visit. They documented each gap without alarm—just clear remediation steps our CFO could present to the investment committee.

The multisig appendix alone justified the retainer. Our estate attorney finally had a readable chain-of-custody narrative instead of a folder of screenshots.
