What Holders Say After a Visit
After the audit I finally knew which Ledger held my altcoin positions and which held long-term BTC. The binder sits in our safe now — my spouse can find everything without asking me seventeen questions.— Min-jun P., Seomyeon, Home Vault Audit, March 2025
The seed phrase verification caught moisture damage on one paper backup I had forgotten about. Replacing it that week probably saved me a headache, though the session ran longer than I expected.— Hye-jin L., Haeundae, Seed Phrase Verification, January 2025
