Using MEW Offline (Cold Storage)

 For increased security, you can run MyEtherWallet (MEW) on your local computer, instead of from the GitHub servers through our website. The computer being used should not be connected to the internet. You can generate a wallet completely offline and send transactions on a different computer, which must be connected to the internet, from our ‘Send Offline’ section. In this way, your sensitive information (i.e. private key, keystore file, mnemonic phrase) is kept on an offline device, and it is never transmitted off your device.

Downloading and Running MEW Offline

Step 1. In order to set up your local MEW, start by downloading the latest release of MEW here.


Step 2. Click on MyEtherWallet-vX.X.X.X.zip to download the file. Move this file to a USB stick (or another storage transfer device), and transfer it to your permanently-offline computer.


Step 3. Plug the USB into your offline computer and extract all the files into the archive of the computer. Extracting the files is important, otherwise MEW will not open correctly and will look like a bunch of nonsense. You should end up with a folder containing these files:


Step 4. To open MEW, double-click the ‘index.html’ file. This will open MEW in your browser. You will get a warning saying it is unable to connect to the network, which is normal. You’re not connected to the internet. You won’t be able to see your ETH or token balances because of this, but these are viewable in a secure, public way by using an Ethereum blockchain explorer such as etherscan.io or ethplorer.io.


Congratulations, you’re running MEW offline! Make sure to repeat this process periodically, to ensure you’re on the most up-to-date version of our interface.

Thanks for the tutorial, it's useful for new member, I know that Mew offline is for increase security, but how about if direct using hardware wallet, do you still recommend hardware wallet + Mew Offline? some people told me it's protect dns attack.

I like that meW continues to evolve. But I have not yet put this wallet neby time. Yes, and it is necessary to study the issue in detail. Look at the first reviews.

This is actually a good tutorial for peoples who want to store their eth or tokens for long time.
Using cold storage is the best way to store your ETH and tokens there, i would say it is the safest and cheapest way.
But you must make sure the link download is a legit one, always check the site you download the file.
