The Ledger Blue
The Ledger Blue features an LED-backlit colour touch-screen, a lipo rechargeable battery and a USB port. There is a power button on the device, you can therefore turn on your Ledger Blue without connecting it to a computer. The device can be connected to a computer or a smartphone through the USB cable. In order to make the Ledger Blue compatible with all USB ports, you can use an On-The-Go Adapter.
Download Ledger Live, the companion app to your Ledger Blue device to get started.
- Press the power button on the side of the device.
- If there is no battery left, connect your Ledger Blue device to a computer or a wall socket.
- You can now choose:
- To configure your Ledger Blue as a new device with an original seed
- To restore a previous configuration
- - If you want to create a new seed, select “Configure as new device”
- If you want to import a seed that you already have, select “Restore Configuration”
- Choose a PIN code. Depending on the firmware you have, the number of digits can vary.
- In order for the PIN code to be validated, the 24 words must be validated as well.
24-Word recovery phrase
The 24 words (also called the ‘seed’ or the ‘recovery phrase’) will be displayed 4 at a time. You must carefully write down each word on the recovery sheet, in the order displayed on the screen. Please note that the 24 words are only shown once during initialisation. This stage is crucial, as the 24 words constitute the proof of ownership of the account, as well as the backup of your funds.
- Find the Recovery Sheet, which is placed in the Ledger Blue box.
- You must write down the 24 words on the Recovery Sheet, in the correct order. Start by writing down the first word (Word #1). Please ensure correct spelling of the word before proceeding to the next one.
- Write down the second word (Word #2) on the Recovery Sheet. Please ensure correct spelling of the word before proceeding to the next one.
- Write down the third word (Word #3) on the Recovery Sheet. Please ensure correct spelling of the word before proceeding to the next one.
- Repeat the previous step until you have written down all the 24 words.
Before proceeding, you should check the words on the Recovery Sheet, to ensure correct order and spelling. Please note that this step is an important safety measure.
The 24 words:
- Ensure that you are the only person who can access your funds.
- Can recover your funds if you lose your Ledger Blue device.
- Are only shown once during initialisation.
- Validate the 24 words on your Ledger Blue, through a confirmation process.
PLEASE STORE THE RECOVERY SHEET IN A SAFE LOCATION. THE RECOVERY SHEET PROVIDES DIRECT ACCESS TO YOUR FUNDS.
IF YOU LOSE YOUR 24 WORDS, YOU WILL LOSE ACCESS TO YOUR FUNDS.
NEVER SHARE YOUR 24 WORDS WITH ANYONE. DO NOT SAVE THEM ON YOUR COMPUTER OR ON YOUR SMARTPHONE. PLEASE ENSURE THAT THE 24 WORDS ARE SAFELY STORED.
When your Ledger Blue displays “Your device is now ready”, your device has been configured.
Applications on your Ledger Blue
A multi-application device
You can install and uninstall several applications such as Bitcoin, Ethereum, XRP and many others (altcoins, authentication, etc.). Some of them are provided by Ledger and some by other companies.
By default, there are already some applications installed on the Ledger Blue:
- FIDO U2F
These applications can be removed or replaced. You can add new applications through the Ledger Manager, which acts as a free app store to download and delete your applications.
Note that your Ledger Blue can hold up to 8 applications at the same time. Moreover, these can be changed on an on-going basis through the Ledger Manager. Removing an application does not mean that you lose your coins. Once the coin application has been reinstalled, you will be able to see your balance and undertake transactions again.
