Follow the tips given below to ensure you have got the genuine Ledger Nano S wallet:  1. Purchase your ledger wallet directly from Ledger or through the authorized reseller. 2. Check the contents of the packaging which should include a Ledger Nano S, “Getting Started” leaflet, a “Knowledge is power” card, either one or three blank Recovery sheets (depending on the production date), Additional accessories (keychain and a lanyard) and packaging (unmarked foam/cardboard). 3. The device should have factory settings, that is, it should display the Ledger Logo when switched on and when the buttons are released “Welcome to Ledger Nano X” should be displayed. 4. Ledger never provides a PIN code in any way, shape, or form and so if it asks for one without you setting it up in the first place, chances are the device is compromised. 5. Check authenticity with Ledger Live. The devices come with a unique private key and only genuine Ledger wallets will be able to provide the cryptographic proof required to connect the device with Ledger servers.
