Hardware Device Health Check
Firmware currency, passphrase configuration, and physical condition assessment for Ledger, Trezor, Coldcard, and similar devices.
Overview
Bring your hardware wallets to our Daegu office for a hands-on inspection. We verify firmware versions, test device responsiveness, check for physical damage, and confirm passphrase entry procedures — all without accessing your private keys.
Included
- Firmware version check against manufacturer recommendations
- Boot sequence and screen responsiveness test
- Physical inspection for tampering, corrosion, or connector wear
- Passphrase entry method documentation
- Replacement timeline recommendation if device age warrants it
Note
This session requires physical access to your devices. Video sessions are available for firmware guidance only; physical inspection must be done in person.
