Hardware Wallet Setup Session

Step-by-step initialization of your Ledger, Trezor, or compatible device with verified backup procedures.

Your seed phrase deserves a quiet room, not a chat window

Most wallet mistakes happen because someone rushed through a setup guide alone at midnight. Our sessions give you a dedicated hour and a half with a practitioner who has reviewed hundreds of beginner setups across Ledger, Trezor, and paper backup methods.

We never ask you to share your seed phrase digitally. Everything happens on paper, face to face, in our Jung-gu office.

What beginners say after their first session

I walked in with a Ledger still in its box and left knowing exactly where my recovery sheet lives and why I should never photograph it. The practitioner was patient when I asked the same question three times.
— Min-jae P., hardware wallet setup, March 2025
The session was thorough, though I wish we had spent more time on passphrase options. Still, I finally understand the difference between a hot wallet and cold storage.
— Sarah L., beginner review session, January 2025
