How to install and use Ethereum and Ethereum Classic?

The Ledger Nano S and The Ledger Bue manage Ethers (ETH and ETC) tokens. It works on Windows (7+), Mac (10.8+), Linux or Chrome OS. It requires Google Chrome or Chromium, and one USB port to plug your Ledger Nano S or your Blue. it doesn't work on Android and iOS.

The Nano and the HW.1 don't support Ethereum.


1. install the Ledger Wallet Ethereum application on your computer 

  • Go to this page and click on the "GET THE APP" green button
  • Download the Ledger Wallet Ethereum application
    (the application is signed by an "Epic Dream SAS" certificate) 
  • Open the downloaded folder to install it:
    - On Mac, you must run a 10.8+ OS
    - On Linux, don't forget to set up the updev rules
    - On Windows, you must run at least Win7: click on "Additional Information" to launch the installation despite the anti-virus warning (it won't affect the integrity of your PC)

 

2. install the Ethereum application on your device via the Ledger Manager

These 2 first steps are only required once. Now everything is ready to manage your Ethereum account.
 
 

3. Once these apps are installed, to open your Ethereum account, just:

  • Open your Ethereum application on the device itself
  • Disable the "Browser support" setting:
    ON A NANO S
    - scroll with the right button to find the "settings", press both buttons to open them
    - scroll with the right button to find the "browser support", press both buttons to open it
    - select NO by pressing both buttons to disable the browser support
    ON A BLUE
    - tap on the top left menu
    - disable the "browser support" by taping on it to make the slider displayed in grey
  • Launch the Ethereum Chrome app on the Chrome or Chromium browser on your computer 
  • Chose ETH if you want to manage Ethereum, ETC if you want to manage Ethereum Classic

 

  • It will open your Ethereum (or Ethereum Classic) wallet
  • The wallet synchronizes and opens

 

 HOW DOES IT WORK

This application is an account manager, where you can send and receive Ethereum transactions and check your balance.

The only way to open it is to connect your Nano S or Blue, make your PIN code and launch the Ethereum app on your device. Without the device, the app won't launch.

You'll then have to choose on your computer between Ethereum and Ethereum Classic. Please be careful to choose the right wallet as it would be difficult - but not impossible - to recover tokens sent on the wrong account.

For each sending transaction, your application will ask you to verify it on your device: your device will display the amount, recipient address and gas rate you will have to manually sign by confirming everything is alright on the device.


UPDATES & TROUBLES

The Ethereum application updates automatically, you don't have anything to do. Each time Ledger releases an update, it will be synced after a few hours on your computer. If you want to force an update to the latest version, just restart Chrome.

If your Ethereum app doesn't open, please consult this article.
