Portal Cedar Line helps holders of dormant Ledger, Trezor, and Coldcard devices prepare for recovery before funds become permanently inaccessible. We work from our Daejeon office with physical devices and backup materials — never remote access to your keys.
Flagship Consultation
For holders who have not accessed a hardware wallet in years, our assessment session catalogues the device model, firmware generation, passphrase configuration, and backup material condition. We produce a written recovery readiness report you can act on independently or with a specialist.
Sessions run 90 minutes at our Seo-gu office. Bring the physical device, any steel or paper backups, and purchase records if available.
