Cold Wallet Documentation Package
A structured binder of device inventories, custody attestations, dual-control procedures, and chain-of-custody logs for offline holdings.
SecureSaaS
Compliance-ready cold wallet documentation and transfer verification for small digital-asset firms that need a clear paper trail before the next audit or large withdrawal.
Flagship engagement
Cold wallet records you can hand to counsel or an examiner
We assemble device inventories, seed-phrase custody attestations, multi-sig ceremony notes, and chain-of-custody logs so your firm can show how offline holdings are controlled — without turning your vault into a product pitch.
Each documentation package is scoped to the wallets you actually hold: hardware serial registers, air-gapped signing device logs, dual-control procedures, and transfer approval trails. We work on-site in Seoul or remotely with sealed document packs.
Excluded by design: key generation, holding assets on your behalf, or software custody products. You keep the devices; we structure the evidence.

What firms notice after the binder is complete
“We finally had serial numbers, dual-control sign-offs, and withdrawal checklists in one place. Our counsel still asked for clarifications on two multi-sig ceremonies, but the gaps were easy to fill.”— Operations lead, Seoul digital-asset trading desk
