Ethereum (ETH) and Bitcoin (BTC) are built on fundamentally different blockchain architectures. Often, Bitcoin is referred to as Blockchain 1.0, while Ethereum is considered Blockchain 2.0. This means that a wallet supporting Bitcoin (BTC) does not necessarily support Ethereum (ETH).
Any Ethereum wallet can store ERC20 tokens, such as CTXC, ELF, ZIL, or XRP. ERC20 is a technical standard used for smart contracts on the Ethereum blockchain for implementing tokens. Any token developed under the ERC20 standard can be stored in an Ethereum-compatible wallet. If a token does not comply with the ERC20 standard, it may require a custom-developed wallet for storage.
Having a personal Ethereum wallet is essential. Once you purchase ETH or other tokens on an exchange, you can transfer them to your private wallet. This adds a layer of security and helps avoid potential losses if an exchange is compromised—for example, in cases of hacking, such as the January incident where Japanese exchange Coincheck lost $500 million.
One of the most well-known and widely used Ethereum wallets is MyEtherWallet, often abbreviated as MEW.
Understanding Key Concepts
Before diving into the wallet creation process, it’s important to understand a few basic concepts. When you create a cryptocurrency wallet, you will receive two critical pieces of information:
- Wallet Address: Think of this as your bank account number. It’s a public identifier that others can use to send funds to your wallet.
- Private Key: This is akin to having your ATM card and PIN combined. Anyone with access to your private key has full control over your funds. Store this securely, as losing it means your wallet cannot be recovered.
Thanks to the transparent nature of blockchain, anyone with your wallet address can view your transaction history and current balance—which addresses have sent you funds and how much you hold.
MyEtherWallet is an open-source project, meaning its code is publicly auditable for security. It does not rely on a central server or store user wallet data. All private keys and passwords remain exclusively with the user. Importantly, wallets created with MEW can also be accessed using other Ethereum wallet interfaces like MetaMask, Mist, or imToken—similar to accessing your bank account from different branches.
Step-by-Step Guide to Creating Your MEW Wallet
Follow these steps carefully to set up your Ethereum wallet using MyEtherWallet.
Step 1: Access the Official Website
Navigate to the official MyEtherWallet website. Always double-check that the address bar displays "MYETHERWALLET INC" in green to confirm you are on the legitimate site and avoid phishing scams.
Step 2: Select Your Language
The website defaults to English, but you can switch the language using the menu in the top-right corner. Both Simplified and Traditional Chinese are available, among other languages (note that translations may be partial).
Step 3: Create a New Wallet
Click on "New Wallet." You will be prompted to set a strong password. This password encrypts your private key for security. Remember, the password alone is not enough to access your wallet; it must be used together with the Keystore file.
Step 4: Download Your Keystore File
After setting your password, download the Keystore file (also known as a UTC/JSON file). This file is an encrypted backup of your private key. Store it securely offline, such as on a USB drive. You will need this file and your password to access your wallet in the future.
Step 5: Secure Your Private Key
Your unencrypted private key will be displayed. This is the most critical piece of information for recovering your wallet if you forget your password or lose the Keystore file. Never share this with anyone, and store it in a safe, offline location.
Step 6 Save Your Paper Wallet
You will also have the option to print or save a paper wallet. Treat this physical copy with extreme care, as it contains your private key and QR code for easy access.
Step 7: Unlock and Verify Your Wallet
Before finishing, MEW will prompt you to unlock your wallet to ensure everything was set up correctly. You can do this by selecting "Keystore / JSON File," uploading the file you just downloaded, and entering your password. While you can also unlock using the private key directly, this method is less secure and not recommended for regular use.
Step 8: Access Your Wallet Dashboard
Upon successful unlock, you will be taken to your wallet dashboard. Here, you can view your Ethereum address, balance, and transaction history. You can also re-download your Keystore file or paper wallet details if needed.
Congratulations! You have successfully created your own Ethereum and ERC20 token wallet. You are now ready to safely receive, store, and send ETH and any ERC20-based tokens.

Frequently Asked Questions
What is the difference between an Ethereum wallet and a Bitcoin wallet?
They are built for different blockchains. A Bitcoin wallet handles BTC and sometimes Bitcoin-based tokens, while an Ethereum wallet holds ETH and any tokens issued on the Ethereum network, like ERC20 tokens. They are not interchangeable.
Can I use my MEW wallet with other wallet applications?
Yes. Since MEW generates a standard Ethereum wallet, your private key, Keystore file, or mnemonic phrase can be used to access the same wallet on other compatible platforms like MetaMask or Trust Wallet.
What happens if I lose my Keystore file and forget my password?
If you lose both your Keystore file and your password, your funds will be permanently inaccessible. This is why it is crucial to securely back up your private key and/or mnemonic phrase separately, as they are the only recovery methods.
Is MyEtherWallet free to use?
Yes, creating a wallet and viewing your balance is free. However, sending transactions or interacting with smart contracts on the Ethereum network requires paying a gas fee in ETH, which is paid to network validators, not to MEW.
Are there any risks in using an online interface like MEW?
The main risk comes from phishing sites. Always ensure you are on the official MyEtherWallet website. Your keys are stored locally by you, not on MEW’s servers, so your security largely depends on your own practices.
Can I store non-ERC20 tokens in my MEW wallet?
No. MEW only supports Ethereum-based assets. Tokens that do not follow the ERC20 (or other Ethereum standards like ERC721) must be stored in a wallet specifically designed for their native blockchain. Always confirm a token's standard before attempting to store it.
