MyEtherWallet Guide: How to Use MEW Wallet Safely and Efficiently

·

MyEtherWallet (MEW) is one of the most trusted and user-friendly Ethereum wallets available today. Designed for both beginners and experienced users, MEW allows you to securely manage and store Ethereum (ETH) and ERC20 tokens with full control over your private keys. This comprehensive guide walks you through every essential step—from creating a wallet to sending transactions, adding custom tokens, backing up your data, and maintaining top-level security.

Whether you're new to decentralized finance or expanding your crypto toolkit, this tutorial ensures you can use MyEtherWallet confidently and safely.

Creating a MyEtherWallet Account

The first step in using MEW is setting up your wallet. Unlike custodial services, MyEtherWallet gives you complete ownership—meaning no third party controls your funds.

Follow these steps to create your wallet:

  1. Visit the official MyEtherWallet website at myetherwallet.com. Always double-check the URL to avoid phishing sites.
  2. Click on "Create a Wallet" in the top-right corner.
  3. Choose the "Keystore File" option for enhanced security.
  4. Set a strong password—this protects your encrypted private key. Never reuse passwords or store them online.
  5. Click "Next", then download your keystore file. Save it in a secure, offline location like a USB drive or encrypted storage.
  6. Confirm you’ve saved the file by clicking "I understand, continue".
  7. Your wallet is now created! You'll see your public address (starting with 0x)—this is where others can send ETH or tokens.
🔐 Your keystore file + password = full access to your wallet. Losing either means permanent loss of funds.

Sending Ethereum and Tokens via MEW

Once your wallet is funded, sending ETH or ERC20 tokens is simple and fast.

  1. Access your wallet by selecting "Access My Wallet" on the homepage.
  2. Choose "Keystore File", upload the file you downloaded earlier, enter your password, and unlock.
  3. Navigate to "Send Ether & Tokens".
  4. Enter the recipient’s Ethereum address carefully—transactions are irreversible.
  5. Input the amount you wish to send.
  6. Select the transaction speed (gas fee): Low, Medium, or High, depending on network congestion.
  7. Review all details, then click "Generate Transaction".
  8. Confirm the transaction in the pop-up window and click "Send Transaction".

After a few seconds to minutes (depending on gas fees), the recipient will receive the funds.

Adding Custom ERC20 Tokens to Your Wallet

MEW supports thousands of ERC20 tokens. If a token isn’t displayed automatically, you can manually add it.

  1. After logging in, scroll down to the "Tokens" section.
  2. Click "Add Custom Token".

  3. Fill in the following details:

    • Token Contract Address: Found on Etherscan or the project’s official site.
    • Token Symbol: Usually auto-filled once the contract is recognized.
    • Decimals: Typically 18 for most tokens (check official sources if unsure).
  4. Click "Save".

The token will now appear in your balance list whenever there’s a balance or incoming transfer.

💡 Tip: Only add tokens from trusted sources—malicious contracts can drain funds if interacted with improperly.

Backing Up and Recovering Your Wallet

Protecting your wallet from hardware failure, theft, or accidental deletion is critical.

How to Back Up Your MEW Wallet

  1. Log into your wallet using your keystore file and password.
  2. Click the person icon in the top-right corner and select "View Wallet Info".
  3. Re-enter your password when prompted.
  4. You’ll see your keystore file again—download and save it in multiple secure offline locations.

Recommended backup methods:

Never store backups in cloud services like Google Drive or email.

Recovering Your Wallet on a New Device

  1. Go to myetherwallet.com and click "Access Wallet".
  2. Select "Keystore File".
  3. Upload your backed-up .json file.
  4. Enter your original password to unlock.

Your full wallet—including all tokens and transaction history—will be restored instantly.

Essential Security Tips for Using MyEtherWallet

While MEW is non-custodial and secure by design, user behavior plays a major role in safety.

1. Avoid Phishing Websites

Always verify that you’re on https://www.myetherwallet.com. Bookmark the site and avoid clicking links from emails or social media.

2. Use MEW Offline for Maximum Security

Download the open-source MEW CX Chrome extension or use the desktop version to sign transactions without connecting to the internet.

3. Never Share Your Private Key or Password

No legitimate service will ever ask for your private key or password. Keep them secret.

4. Enable Two-Factor Authentication (Optional)

While MEW itself doesn’t host accounts, integrating with hardware wallets adds an extra layer of protection.

5. Store Large Amounts in Cold Storage

For significant holdings, consider transferring funds to a hardware wallet like Ledger or Trezor. MEW integrates seamlessly with both via USB or Bluetooth.
