Hello Guys, I want to share with you how to make an Offline EGEM wallet. This information is derived from a post submitted to Ethtrader subredit a while ago. I just updated the information to reflect the support for EGEM, so I hope you find it useful.
How to generate a wallet in a safe way: air gapped paper wallet
Get a USB stick and create a bootable version of Ubuntu, there are many guides on how to do this. Here is one for Windows Users. Here is one for Mac users. Here is a video on YouTube for how to do it. By the end of this first step you should have a USB stick that you can boot Ubuntu from.
Download the EGEM wallet from here. Extract the contents of this zip file to a folder on a flash drive. You can use the same flash drive that you just created for Ubuntu, just make a folder such as flashdrive/myegemwallet and stick the website contents in there.
You have to now boot your computer from the USB stick. Mac users can just insert the USB stick, hold option, power up their computer and then select "Ubuntu live cd" or "Ubuntu". Windows users have to follow these steps with the USB stick inserted and then pick the USB stick from a list of boot options.
At some point booting from the USB stick, select "live cd" or "try ubuntu before installing". NEVER EVER SETUP WIFI, UNPLUG YOUR INTERNET CORD IF YOU ARE WIRED IN!
Once Ubuntu boots, find the flash drive in the file explorer with the MyEgemWallet files, and open up egemwallet-mercury\chrome-extension\index.html
To create a new EGEM wallet, go to the New Wallet tab and Enter a password. Think up a password (you absolutely shouldn't forget this) and click "Create New Wallet". Then click "Download Keystore File (UTC/JSON)" and find the file that got downloaded and STICK THIS ON THE FLASH DRIVE - you absolutely shouldn't lose this! Then select "I understand. Continue"
Write down the private key that they give you. Write it on paper, double and triple check it. Copy it to a text file and save it onto the flash drive. You absolutely shouldn't lose this!
You shouldn't print your wallet unless you can connect to a usb printer. Otherwise you would need network access to print. What you can do though is click on "print", cancel the print dialogue and then go to "file > save" and save the webpage on your flash disk.
Click "Save your address", select "Keystore File (UTC / JSON)" and then "Select Wallet File" and open the .json file you saved on the flash disk earlier. Then provide the password you entered in step 6 and click "Unlock". If all is correct you will get a "Wallet successfully decrypted" message and your Public EGEM address will be displayed; this is your Public address to receive your EGEM transfers.
You have now generated an EGEM wallet. Nice job. I highly suggest you now insert a second flash disk and copy EVERYTHING from the first one onto the second. Then store them in different places. The idea here is that you make several copies of your public and private key so you don't lose them.
NEVER EVER PLUG THESE USB STICKS INTO ANOTHER COMPUTER AGAIN - only access these USB sticks from Ubuntu, booting it up the same way you did in the steps above ^
You should now try sending a small amount of EGEM to this new wallet, and then use https://explorer.egem.io/home to make sure the transfer goes through.
You should now try sending a small amount of EGEM out of your new wallet to make sure it works. You should only ever send EGEM from this new wallet by booting Ubuntu up and sticking the USB sticks into your computer. From an online computer go to the MyEgemWallet.com website and go to the "Send offline"tab. Then put your new wallet's public address in, then click "Generate Information" and copy down gas price and nonce to a textfile on A NEW AND DIFFERENT USB stick. Go back to your offline computer with Ubuntu and open up index.html again and click "Send Offline" on the navigation at the top. Where it says "Step 2" insert the To Address of your old wallet, and put a small amount of EGEM in for value, and then fill in gas price and nonce from the text file you saved on that new USB stick. Check the "Keystore JSON" box and click "SELECT WALLET FILE" and give it the .json file you saved from step 6, then click "Generate Transaction". It will now give you some long string of text in the "Signed Transaction" box. SAVE THIS TO THAT NEW USB STICK DON'T REUSE THE ONE WITH THE .JSON FILE AND YOUR PRIVATE KEY! Stick this new USB stick into the online computer, and go to the MyEgemWallet.com again, in the box labeled "signed transaction" paste that text you just saved in and click "Send Transaction". BOOM.
If this works then you now a) know your brand spanking new wallet works and b) know how to do a super secure offline transaction - hackers be damned you're pretty secure and safe now!
