Quick usage examples

[!TIP] The examples below are only a subset of available commands. The complete list of commands and detailed usage instructions is described in the official documentation.

1. Sign and send a Bitcoin transaction

1. Create or obtain a raw unsigned transaction externally.
2. Run the signing & send command:
   cryptnox btc send <recipient_address> <amount> [-f <fees>]

2. Dual initialization

1. Factory reset each card:
   cryptnox reset → enter PUK → verify reset.

2. Initialize each card:
   cryptnox init → (optional) set name/email → set PIN (4–9 digits) → set or generate PUK → verify init.

3. Run dual seed procedure:
   cryptnox seed dual — follow prompts: insert Card A (enter PIN), swap to Card B (enter PIN), swap back as requested.

3. Change PIN code

1. Run command: cryptnox change_pin
2. Enter current PIN → enter new PIN → verify change.
3. Check with cryptnox info using new PIN (BTC & ETH accounts displayed).

4. Get extended public key (xpub)

1. Run command: cryptnox get_xpub
2. Enter PIN → enter PUK
3. The card returns the xpub
