General Ledger Nano / HW.1 FAQ

What are the differences between the Nano and the HW.1?

The Ledger HW.1 is a low cost version of the Ledger Nano. It has exactly the same properties and level of security, and from the usage point of view it is exactly the same thing.

If you order a Ledger HW.1 Multisig, you will get three HW.1 keys containing each their security code and recovery sheet. For the Enterprise pack, you'll get 10 full HW.1 sets.

The key form factor is the main difference between the two products. It is very strong and reliable, but it definitely looks "cheaper" than the Ledger Nano metal counterpart. Also, you'll get the HW.1 brand, the plastic key doesn't have any mention of the Ledger brand.

How to initialize the Ledger Nano?

The following video demonstrates the installation process and basic usage of the Ledger Wallet : 

  1. Be sure to have the latest version of Google Chrome and go to 
  2. Follow the instructions and install the Ledger Wallet Chrome application.
  3. Insert the Wallet in any USB port.
  4. When asked to, enter a PIN code of your choice for your Ledger Wallet, or select a random one. Make sure you will remember it.
  5. Write down the 24-word passphrase which is a backup of your private keys. DO NOT SKIP THIS STEP. It is the only way to retrieve your bitcoins if your Wallet is stolen, damaged, or if you lose your PIN code.
It is extremely important to secure your recovery sheet (containing your backup), and to NEVER allow any access to it. Anyone who would have a copy of your 24 words seed could steal all associated bitcoins.

How to use my smartphone as a second factor?

You can pair a smartphone (Android, iOS) to your Nano in order to get a much smoother transaction verification process. First, you need to install your mobile companion app on your smartphone:

Once it's done, open your Chrome app and connect your Nano. To pair your smartphone you must initiate a transaction (you won't have to confirm it to finish the pairing, or just send 0.001 bitcoin to yourself). Select "pair a smartphone" and follow the instructions (video).

How to transfer all my bitcoins to my new Ledger Nano?

After initialization of the Ledger Nano, you'll get a deposit public address which you'll be able to send your bitcoins to. It is not possible to import any private keys into the wallet, so all transfers can only be done using a standard Bitcoin transaction.

How to verify a transaction with the security card?

Whenever you need to do a payment, the wallet will verify 4 letters/numbers from the payment address by asking you to enter the corresponding character on the security card (for instance, "A" will correspond to a "3" on the card), as well as the characters corresponding to the amount to be paid.

This will ensure that no malware has replaced the address or the amount to be payed when asking the Ledger Wallet to sign the transaction.

How to initialize the Nano "Duo Edition"?

First, you need to follow the installation procedure for the Nano.

You should now have your first Nano initialized, and your 24 words seed backup on your recovery sheet.

Now, follow these instructions:

  1. Remove the first Nano from the USB port, and insert the second one
  2. Select "Restore an existing wallet", and click "Continue"
  3. Enter and confirm your PIN (to avoid confusion, we recommend to use the same PIN, but you can also chose a different one)
  4. Type in the 24 words in the correct order, and click "Continue"
  5. You now have two cloned Nano that can be used independently

If something goes wrong in the seed restoration, check each of the words carefully. In case of total failure, you can reset both Nano by entering a wrong PIN three times in a row, and start again all the initialization procedure.

How to update the Nano firmware?

When a new firmware is available, the Ledger Chrome app will give you the opportunity to update it. As the update will erase your seed, you must have your recovery sheet with you (24 words and security card QR code).

Follow the instructions, the process is quite straightforward (video). If you are on Linux, you may have to add a line in the udev rules (instructions will be given).

How to use the landyard and keyrings with the Nano?

In each box you'll find a keyring and a lanyard, so you can always keep your Nano with you.

To put the Nano on the lanyard, start by making the smallest chord go through the wallet's hole:

Then make a little more room for the biggest chord to go through: 

(you can detach the lanyard from the plastic clip, but I've found that to make the handling a bit harder)

Put the other extremity (biggest chord) through the smallest chord and pull all the way through:

You'll have to fiddle with the last few millimeters of the whole (the plastic clip has to go through the smallest chord), but you should end up with this: 

You can also use the small cord to attach your Nano to a keyring:

How to assemble the HW.1?

It is very easy! Just look at this video:

Can I use the Nano or HW.1 with an Android phone?

Yes, for Android phones. You need however an OTG adapter as well as select a compatible Android wallet app (Mycelium or GreenBits).

Right now, the Ledger Wallet (our Chrome app) is not available on Android or iOS.
