Annual Custody Review
A full-year planning and execution package for examining offline wallet reserves, updating inventory ledgers, and filing signed custody reports.
Custody Reviews
Scheduled examinations and documentation services for offline cryptocurrency reserves, seed phrase custody, and cold storage sites.
Our review services are delivered on-site or at our Jeju office. Each engagement produces written custody records suitable for trustees, attorneys, and family signatories who must verify offline holdings without connecting devices to the internet.
Cold Storage Site Mapping
Field documentation of every offline location where reserves are held — vault boxes, home safes, attorney custody, and mainland relay points.
Recovery Rehearsal Session
Supervised offline drill to confirm that documented recovery steps produce the expected test wallet balances without exposing live seed material.
Seed Phrase Documentation Audit
Independent verification that seed phrase envelopes, metal backups, and passphrase records are labelled, sealed, and stored according to your custody map.
