When this applies
Families and small partnerships sometimes accumulate multiple hardware wallets over years — a Ledger from 2016, a Trezor purchased during a later cycle, a Coldcard added for air-gapped signing. Without a clear inventory, recovery attempts can target the wrong device or backup set.
What we produce
During the session we catalogue each device by model, approximate purchase period, and associated backup materials. We create a household inventory document (provided as a printed summary and encrypted PDF) mapping devices to their backup sets and noting any gaps.
Constraints
Maximum four devices per session. We do not power on devices or connect them to networks. Additional devices require a follow-up session at ₩120,000 per hour.
