Every cold wallet deserves a written record
Page Aspen Hub conducts on-site and remote inventory audits for individuals who keep cryptocurrency in hardware wallets, paper backups, and offline vaults. We reconcile what you own with what you can prove.
What we verify
Three pillars of a cold storage audit
Device inventory
We catalogue every hardware wallet, air-gapped computer, and signing device in your possession. Serial numbers, firmware versions, and passphrase policies are recorded in a tamper-evident report.
Backup reconciliation
Seed phrases, Shamir shards, and metal plates are cross-checked against your written inventory. We flag duplicates, missing copies, and storage locations that violate your own stated rules.
Holdings alignment
Public addresses derived from your keys are matched to exchange withdrawal records and personal ledgers. Discrepancies are documented with suggested next steps — never with trading recommendations.
Audit offerings
Engagements for private holders

From our clients
What holders say after an audit
After my father passed, I found three Ledger devices and a safe-deposit box key with no instructions. The audit team mapped each device to its addresses and identified one wallet I had never heard of. The report took longer than I expected, but every page was worth keeping.— Hyeon-ju R., post-inheritance reconciliation, Bundang
I thought my seed backups were fine because I had two copies. The review showed both were stored in the same apartment — exactly what my own written policy forbade. Straightforward correction, no lecture.— Marcus T., backup review, Itaewon
