To ensure that a new ledger (e.g. a Ledger Nano S, Ledger Nano X or Ledger Stax) has not been tampered with, you should carry out the following steps: 1. check the original packaging - Make sure that the packaging is unopened and undamaged. - Ledger does not seal the packaging with security stickers to prevent users from relying on counterfeit seals. Instead, look for signs of tampering, such as adhesive residue or double-sticked areas. 2. check the device the first time you switch it on - The first time you switch on the device, it should ask you to set a new PIN. - If the device already has a PIN or you do not have the option of setting a new PIN, it may have been tampered with. - The device must not have a pre-installed recovery seed list! - If a "recovery seed" has been supplied or the device shows you a predefined seed phrase, you should not use it under any circumstances! 3. use official Ledger Live software - Only download Ledger Live from the official website (https://www.ledger.com/ledger-live) - Connect your device to Ledger Live and check whether it is recognised as authentic. - In Ledger Live under "Settings" → "Device verification" you can verify the authenticity of your device. 4. check firmware version and updates - Make sure that the device is running an official firmware version from Ledger. - Open Ledger Live → "Manager" and check whether a firmware update is offered. - If your device contains an unknown or not officially signed firmware, you should not use it. 5. check for hidden hardware manipulation - If you have any doubts, you can visually check the device for tampering: - Are screws or housing edges damaged? - Are there any signs of openings or soldered components? If you have any suspicions: Do not use the device and contact Ledger Support!
