How to Set Up MyEtherWallet (MEW) Safely in 2026

MyEtherWallet (MEW) is one of the oldest Ethereum wallet interfaces. It lets you create or access an Ethereum address, view balances, send ETH and tokens, and connect to apps. It is non-custodial: MEW does not hold your funds or your keys. The keys live in a file, a recovery phrase, an app or a hardware device that you control. If you lose them, nobody can restore them for you.

MEW is offered in more than one form, and the right choice depends on how you plan to use it.

Option	Best for	Where the key lives
Website (MEW web)	Occasional use, connecting a hardware wallet	Depends on how you access it: hardware device, keystore file or phrase
Mobile app (MEW wallet)	Everyday use from a phone	Encrypted on your phone, with a recovery phrase as backup
Browser extension	Using dApps in your desktop browser	Encrypted in the browser, with a recovery phrase as backup

A simple rule of thumb: use the mobile app or extension for small, everyday balances, and pair the website with a hardware wallet for anything you would be upset to lose. Typing a private key or phrase into a website is the riskiest way to use any wallet, so avoid it where you can.

Product names, supported networks and menu labels change between releases. If a screen in this guide differs from what you see, follow the on-screen prompts and check MEW's help center for the current wording.

Ten minutes of preparation prevents most wallet losses. Work through this list before you create anything.

• Use a clean device. Update the operating system and browser, and run a security scan if you have any doubt about the machine. Avoid shared or public computers.
• Reach the real site. Type the address yourself, then bookmark it and always use the bookmark. Do not click wallet links in search ads, social posts, emails or direct messages. Fake MEW clones are a long-running scam.
• Verify app publishers. In an app store or browser store, check that the publisher is MyEtherWallet and read the reviews and download count. Copycat listings do appear.
• Prepare offline backup materials. You need pen and paper, or a metal backup plate, to write down a recovery phrase. Do not plan to store it in a photo, a notes app, cloud storage or an email draft.
• Choose a strong, unique password. A password manager helps. If you use a keystore file, the password is the only thing protecting it.
• Decide who might need access. Think about whether someone you trust should know where the backup is kept, without learning the words themselves.

No legitimate support agent, MEW team member or giveaway will ever ask for your recovery phrase, private key or keystore password. Anyone who does is trying to steal from you.

The website is the classic way to create a wallet. MEW's own knowledge base describes the flow, and the labels may be reworded over time.

1. Open the MEW website by typing its address or using your bookmark. Confirm the address bar shows the correct domain and a secure connection.
2. Click Create a New Wallet.
3. Choose how you want to protect it. The two common options are By JSON File (a keystore) and a mnemonic phrase.
4. For a keystore, enter a strong password and confirm it. Download the keystore file and keep it somewhere safe. Both the file and the password are needed to open the wallet.
5. For a mnemonic phrase, write down every word in order on paper, then confirm the words when asked. Anyone with the phrase controls the wallet.
6. Return to the access screen and open the wallet using the method you just created, to confirm that it works.

Keystore or phrase? A keystore is encrypted, so a stolen file is useless without the password, but you must keep both safe and cannot rebuild the wallet from memory. A recovery phrase is portable and works in many wallets, but it needs no password, so a copy in the wrong hands is enough to empty the wallet.

Copy your new public address, which starts with 0x, and check it against the address shown after you unlock. Never share your private key or phrase when someone asks for your address. The public address is the only part you give out.

For daily use on a phone, the MEW wallet app is usually more convenient than the website. The key stays encrypted on your device and you unlock it with a PIN or biometrics.

1. Open the official app store on your phone and search for MEW wallet. Check that the publisher is MyEtherWallet.
2. Install and open the app, then choose to create a new wallet.
3. Accept the terms and set a PIN or biometric unlock.
4. The app shows a recovery phrase. Write it on paper in order, away from cameras and other people. Do not screenshot it.
5. Confirm the phrase when the app asks you to re-enter selected words.
6. Open your wallet and look at the network selector at the top left. MEW lets you switch networks there, and Ethereum should be selected for ordinary ETH and ERC-20 use.

If you already own a wallet, choose Restore instead of creating a new one, then enter your existing recovery phrase on the app's own screen. MEW has published guides for recovering old wallets this way, and the same restore logic applies in the extension.

Two cautions apply on mobile. First, a PIN protects the app on your phone, but only your recovery phrase protects your funds if the phone is lost, so the paper backup matters more than the PIN. Second, keep the operating system updated and install apps only from official stores.

If you mainly use dApps on a computer, a browser extension saves you from pasting keys into web pages. MEW's team builds a multichain extension called Enkrypt, and the MEW website also works with other extension wallets. Available options change over time, so check MEW's help center for what is currently supported.

Installing an extension safely

1. Open your browser's official extension store directly, not a link from a message.
2. Search for the extension by name and check the publisher, the number of users and the reviews.
3. Add it to the browser and pin it to the toolbar so you can recognise the real icon.
4. Create a password. This unlocks the extension locally and is not a substitute for your recovery phrase.
5. Write down the recovery phrase on paper and confirm it when asked.
6. Add the networks you need and check the address of each account before receiving funds.

Using the website with an extension wallet

On the MEW website, pick the option to access your wallet with a browser extension. Your extension will ask you to approve the connection, and you will confirm every transaction in the extension popup. In this setup MEW is only the interface, and the extension holds the key.

Treat every connection and signature request with caution. Read what the popup says you are approving, and disconnect sites you no longer use. Keep the browser profile used for your wallet free of unrelated extensions.

There are two common situations: you already have a wallet, or you hold your funds on a hardware device.

Connecting a hardware wallet

Hardware wallets such as Ledger and Trezor keep your private key inside the device. MEW's website can talk to them, so you can view balances and prepare transactions on screen while approving them on the device.

1. Update the device firmware using the manufacturer's own software.
2. Connect the device to your computer by cable, or by Bluetooth where the device supports it.
3. Unlock it with your PIN and open the Ethereum app on the device if it requires one.
4. On the MEW website, choose to access a wallet with a hardware option and pick your device.
5. Select the address you want to use. Different derivation paths can show different addresses, so if you do not see your balance, check that you selected the same path your wallet used before.
6. Check every transaction on the device screen, including the recipient and amount, before you press confirm.

Restoring an existing wallet

In the app or extension, choose Restore and enter your recovery phrase. On the website, choose the access method that matches how the wallet was saved, such as a keystore file with its password. Avoid pasting a raw private key or phrase into the website unless you have no alternative, and never do it on a machine you do not fully trust.

A new wallet is not ready until you have proved that you can both receive and recover funds. Do this with a small amount first.

Receive a small test amount

1. Copy your public address from the wallet. Check the first and last few characters on the screen, not only the middle.
2. Confirm which network you are using. An address works on many EVM networks, but funds sent on one network appear only on that network.
3. Send a small amount of ETH from an exchange or another wallet, and wait until it shows up.

Send a small test amount out

1. Open the send screen and paste the recipient address. Compare the beginning and end of the pasted address to the original. Clipboard-swapping malware changes addresses silently.
2. Enter a small amount, such as one you would not mind losing, and check the network.
3. Review the network fee shown. Fees vary with congestion, so check the live estimate instead of relying on remembered numbers.
4. Confirm, then track the transaction using a block explorer for that network.

Test your backup

Once you are comfortable, restore the wallet from your backup in a different app or on another device using the recovery phrase or keystore. If the same address appears, the backup works. Then delete the test restore from any device you do not plan to use.

Keep some native ETH in the wallet for fees. Without it, you cannot move tokens, even if you hold plenty of them.

Ethereum mainnet is the default, but MEW's apps support other networks too. Always check which network is selected before you send, because a transfer on the wrong network can be hard or impossible to recover.

Adding tokens

Major tokens usually appear automatically. For a custom token, copy the contract address from the token's official site or a trusted listing, then add it manually. Be wary of unknown tokens that appear in your wallet uninvited. Do not interact with them, because some are bait for scam sites.

Moving to layer-2 networks

Many people move ETH from Ethereum to a rollup to pay lower fees. The usual route is the network's canonical bridge. Examples listed on this site include Base Bridge, Arbitrum Bridge, Optimism Bridge, Polygon Bridge and Linea Bridge. MEW has also published a guide to bridging from Ethereum to Base using MEW Mobile, so the flow can be done from inside the app.

Third-party bridges such as Across and deBridge can be faster or support more routes, but they add their own contracts and risks.

Bridge habits to follow

• Start with a small test transfer.
• Check the destination network and the token you will receive.
• Keep a little ETH on both sides for fees.
• Read the expected arrival time. Some withdrawals from rollups take far longer than deposits.

Check each bridge's own documentation for current limits, fees and supported assets, since these change frequently.

Hardware connection problems are common and usually fixable. MEW's help center lists these steps for connection failures:

1. Restart your computer.
2. Use Google Chrome and perform a hard refresh of the page (Ctrl+F5 on Windows, Command+F5 on Mac).
3. Try a different USB cable. Some cables only charge and cannot carry data.
4. Make sure the device is unlocked and the correct app is open on it.
5. Close other programs that may be using the device, such as the manufacturer's desktop software.

Other common problems

• Balance shows zero. Check you are on the right network and the right address or derivation path. Funds are not lost just because a screen is empty.
• Transaction pending for a long time. The fee may have been too low for current demand. Check the transaction on a block explorer before trying anything else. Some wallets let you speed up or replace a stuck transaction.
• Keystore will not open. Password typos are the usual cause. Check for caps lock and keyboard layout, and try the password in a text field you can see.
• Token missing. Add the token contract manually and confirm you are on the right network.
• Extension not detected. Unlock it, reload the page and check that the site is allowed to connect.

If the steps above fail, use MEW's help center, not strangers who contact you first. Anyone who offers help through direct messages is probably running a scam. Real support will never ask for your phrase or private key.

After setup, a few habits protect the wallet for years.

Backups

• Keep your recovery phrase or keystore in at least two secure, offline locations, such as a fireproof safe and a separate trusted place.
• Do not store the phrase and the keystore password together.
• Never photograph the phrase, or store it in cloud services or password managers connected to the internet unless you fully understand the risk.

Daily safety

• Bookmark the real MEW site and use only that bookmark.
• Keep spending money in one wallet and savings in another, ideally on a hardware device.
• Read every signature request. Unlimited token approvals let a contract move a token without asking again, so revoke approvals you no longer need using a reputable approvals checker.
• Be suspicious of urgent messages, surprise airdrops and offers of free crypto.
• Update the app, extension and device firmware only from official sources.

Planning for loss

Decide in advance what happens if your phone breaks, you forget a password or you cannot access the wallet. A tested backup is the answer. For a larger balance, consider whether a trusted person can find your backup instructions if something happens to you.

A wallet shows your transactions publicly. If privacy matters to you, learn the legal and practical limits of privacy tools such as Railgun before using any, and check the rules where you live. Crypto transactions are generally irreversible, so slow down before you press confirm.
