How to make transactions using MyEtherWallet without using your private key online!

in #myetherwallet7 years ago

I haven’t seen any post making transactions using MyEtherWallet without using your private keys. In order to perform this transactions you must have two computers one online and offline PC.
Step 1. First you must download MyEtherWallet software on USB stick and transfer it to offline PC.
Here is the link for instructions.

Step 2. Getting the gas price & nonce
Start off by going to MyEtherWallet site "Offline Transaction" page on your online computer and fill in your address. Please note that this is the address you want to send FROM, not TO.

  1. Filling in the transaction information
    Next, go to your offline computer, open MyEtherWallet and go to the "Offline Transaction" page again. Fill in the TO address and the amount you want to send. Optionally, you can select a token to send from the list. Fill in the gas price and nonce you got from step 1. If you fill in an incorrect nonce, the transaction will fail!
    If you just want to send a transaction to another address (not a contract) leave the gas limit at 21,000. Increasing the gas limit will not get your transaction verified faster, as you can read. If you are sending a transaction to a contract or including any additional data you have to use more gas. Any excess gas will be returned to you. If you want to include data with your transaction, also fill that in now. Unless you are specifically told to include data, you will likely not need it.
  2. Signing the transaction
    The next step is to sign the transaction. This is the part that requires your private key. To do this, you have to unlock your wallet on the offline computer. On the "Offline Transaction" page, scroll down and access your wallet. A Generate Transaction button should appear. Make sure that all transaction information is correct and press the button. You should now see the raw transaction and the signed transaction.
  3. Sending the transaction
    Finally, copy the signed transaction to your online computer. After signing a transaction, it is not possible to change any information of that transaction anymore, so it is safe to copy it to another computer. On the "Offline Transaction" page, scroll all the way down and fill in your signed transaction. Click the Send Transaction button and your transaction should be broadcast.
