Myetherwallet (MEW) Guide – Storing ETH & ERC20 Tokens

About this guide: Our Myetherwallet guide aims to provide straightforward information on how to set up and use the most popular Ethereum and ERC20 token wallet. In the Cryptocurrency market over 80% of tokens are ERC20 tokens. This makes a wallet like Myetherwallet invaluable to nearly any cryptocurrency investor. We always urge strong caution before using any cryptocurrency wallets and encourage you to do your research.

What is Myetherwallet?

MEW is a website where you can generate and access your own Ethereum and ERC20 wallet. It is the most widely used ethereum wallet. ERC20 tokens are simply tokens for cryptocurrency projects built on the Ethereum network. Currently, over 500 crypto projects are built on Ethereum and are ERC20 tokens.

Don’t think of MEW as a bank: they do not have access to your tokens or wallet details. Think of Myetherwallet as an interface where you can interact with your personal wallet. This does mean that you and you alone are responsible for keeping your crypto safe and controlling your wallet. MEW will not be able to help you if anything goes wrong.

Why Do You Need Myetherwallet?

You could keep your tokens in an exchange however, this comes with the risk of the exchange being hacked. Exchanges are essentially unregulated banks, keeping your tokens for you as a third party. It’s a matter of trust.

Crypto can be seen a lot like owning gold, you only “own it” if you are in possession of the asset. In our opinion it is best if we control our own crypto and don’t need to depend on trusting exchanges. That’s where Myetherwallet comes in. In addition, many ICO’s use ERC20 tokens and you can only participate if you have your own ERC20 wallet.

Ready To Take Control Of Your Crypto? Not So Fast, There Are A Few Important Terms You Need To Know…

Private Key: Think of this as a complex password that proves you own the tokens and are authorised to access your wallet. It’s exceptionally important you never share this with anyone. If anyone finds out your private key they can access your wallet and do whatever they choose. A private key is essentially the same as the pin to your bank account; you should treat it the same way.

You get one private key for your wallet. Do not lose it. Otherwise you will likely lose access to all the crypto in your wallet.

Public Key: A public key is essentially the same as your bank account number. It is required for another person to send funds to your wallet. If you have a friend that wants to send you one ethereum, you would give them your public key to execute the transaction.

Keystore File: This is an encrypted file that stores your private key. You password protect this file when creating a wallet on Myetherwallet. Make sure you keep it safe and never share it with anyone.

How To Setup And Use Myetherwallet?

1) Go to Myetherwallet. First make sure that you can see a padlock next to the URL bar and “MYETHERWALLET LLC [US]”, this means you are on the real site. Make sure you bookmark the site, as there are a lot of Myetherwallet phishing sites trying to get access to your funds.

3) Click “Create New Wallet”. You will then be prompted to download your Keystore file. Download it and keep it safe. For maximum security we personally move the Keystore file to a flash drive and delete all traces of it on our computer.

Once done just click the button “I understand. Continue”.

Because, you will never expose your private key, regardless of any viruses on your computer. The private key is stored securely on your hardware wallet. An added benefit is that accessing your wallet is significantly easier and faster.

We will show you how to integrate Trezor and Ledger with Myetherwallet later in this guide. For now, we will assume you wish to use the completely free Keystore / JSON File method. Select this option.

  • To Address: Is the public key for the person or exchange you wish to send ethereum or tokens too.
  • Amount to Send: You can select the token type in the dropdown, if you wish to send a specific ERC20 token.
  • Gas Limit: Gas is the fee paid to Ethereum network miners to process your transaction. Unless you are participating in an ICO we recommend you keep the gas limit at 21,000. Don’t worry about the big gas number. At the time of writing 21,000 gas is the equivalent of a $0.055 fiat transaction fee.
