MetaMask Wallet Extension: How to Install, Set Up and Use It Safely

The MetaMask wallet extension is a self custodial crypto wallet that lives inside your desktop browser. It holds the keys to your accounts on Ethereum and other EVM networks, plus Solana, Bitcoin and more, and lets you approve every transaction or dApp connection from a small popup next to your address bar. If you’ve ever clicked “Connect Wallet” on a DeFi app or NFT marketplace, MetaMask is usually the first option on the list. This guide walks you through what the extension can hold, how its newer multichain accounts work, how to install it without landing on a fake copy, and the safety habits that matter most when you’re the only one holding the keys.

​
What Can the MetaMask Wallet Extension Hold?

The MetaMask wallet extension started as an Ethereum only wallet, but it now supports several ecosystems in one place. According to the official help center, MetaMask manages private keys for Ethereum, Solana, Bitcoin and other blockchains, and it gives you a few different ways to create or bring in accounts.

​
Networks you’ll see in the extension

  • Ethereum and EVM networks: Ethereum mainnet plus layer 2 and EVM chains such as Arbitrum, Base and Linea, all sharing the same 0x address.
  • Solana: native SOL and Solana tokens, with a separate Solana address inside your account.
  • Bitcoin: native BTC added in December 2025, using native SegWit addresses. Taproot support was announced as coming later.
  • Tron: native Tron support arrived on the extension and mobile app in January 2026, according to The Block.
  • Newer additions: MetaMask also added Monad and Sei in 2025 and said more networks would follow in 2026, so check the app for the current list.

​
Account options

  • Recovery phrase wallet: the classic setup, protected by a 12 word Secret Recovery Phrase that only you hold.
  • Social login wallet: on the extension, you can secure a wallet with a Google, Apple or Telegram account plus a MetaMask password.
  • Imported account: bring in a single account with its private key. MetaMask’s help center notes private key import isn’t available for Bitcoin and Solana addresses yet.
  • Hardware wallet account: connect a hardware wallet such as Ledger or Trezor so the keys stay on the device. At the time of the multichain update, hardware accounts were EVM only.
Practical tip: network support has changed a lot in the past year, so treat any list (including this one) as a snapshot. Open the network menu in your own extension to see what’s live today, and update the extension before you go looking for a feature you read about.

​
How Do MetaMask Multichain Accounts Work?

A multichain account is one MetaMask account that holds several addresses at once, each tied to a different type of network. Instead of juggling “Account 1” for Ethereum and “Solana Account 1” separately, you get a single account that carries your EVM, Solana and Bitcoin addresses together. MetaMask rolled this out automatically in Extension version 13.5 and Mobile version 7.57, and it’s now the default account type. The help center says no migration is needed and all your existing addresses stay accessible. If you had extra Solana or EVM accounts, MetaMask pairs them up in order and creates new addresses where needed so every account has a matching set. In day to day use, this mostly means less switching. When you send, you pick the token first and MetaMask uses the right address for that network. When you connect to a dApp, you pick the account and the matching address is connected for you. To copy a specific address on the extension, click the network addresses box under your account name on the home screen, or open Account details. Always double check which network an address belongs to before you share it, because sending Bitcoin to an EVM address (or the other way round) won’t work.

​
How Do I Install the MetaMask Extension on Chrome, Firefox, Edge or Brave?

To install the MetaMask wallet extension, start at the official site, metamask.io, choose your browser, and add the extension from that browser’s own store. MetaMask’s help center lists Chrome, Firefox, Edge and Brave as supported, and it warns against installing from any other source.
  1. Type metamask.io into your address bar yourself instead of clicking a search ad, then select the download or Get MetaMask option.
  2. Pick your browser. MetaMask sends you to the matching store listing.
  3. Add the extension using the store’s button (see the table below), then confirm in the popup.
  4. On Chrome and Edge, MetaMask opens on its own after installing. On Firefox and Brave, click the extension icon to open it.
  5. Pin it so it’s always visible: click the puzzle piece icon at the top right of the browser, then the pin next to MetaMask.
  6. Choose Create a new wallet or import an existing one, then follow the setup steps in the next section.
Brave users: if MetaMask says it isn’t installed or won’t connect, go to Settings, then Web3, set Default Ethereum wallet to None and restart Brave. The help center notes MetaMask doesn’t work correctly when another wallet extension is active, so this applies to other wallet extensions too. Once the fox icon is pinned, you’re ready to create your wallet.

​
Recovery Phrase or Social Login: Which Setup Should You Pick?

When you create a new wallet in the extension, MetaMask asks you to secure it with either a 12 word Secret Recovery Phrase or a Google, Apple or Telegram account plus a password. Both are self custodial. The difference is how you get back in if you switch devices or forget something.

​
Setting up with a Secret Recovery Phrase

  1. Select Create a new wallet, then choose the Secret Recovery Phrase option.
  2. Create a strong, unique password. MetaMask uses it to encrypt your recovery phrase on this device.
  3. Write down the 12 words exactly as shown, in English. The help center says not to translate them.
  4. Store the paper offline somewhere only you can reach. MetaMask advises against cloud storage and password managers for the phrase.
  5. Confirm the phrase when MetaMask asks, and your wallet is ready.

​
Setting up with social login

Pick the Google, Apple or Telegram account you want to link, then create a MetaMask password. You’ll need both to get back in. A recovery phrase still exists behind the scenes, and MetaMask suggests revealing and saving it as a fallback. One thing people miss: the linked social account can’t be swapped for a different one later, so choose the account you plan to keep. Common mistake: taking a screenshot of your recovery phrase. Screenshots sync to cloud photo backups, which is exactly where MetaMask tells you not to keep it.

​
Can I Use MetaMask on Android and iPhone Too?

Yes. MetaMask has official mobile apps on the Google Play Store and Apple App Store, and you can open the same wallet there that you use in the extension. You either sign in with the same social account and password, or import the same Secret Recovery Phrase. The mobile app is handy for checking balances, receiving funds and approving quick actions when you’re away from your desk. Many people keep the extension for heavier DeFi work on a big screen and use the phone app as a companion.
  1. Open the Play Store or App Store and search for MetaMask.
  2. Check the publisher before you tap Install or Get. On Android, the help center points out the official app has more than 10 million downloads, which helps you spot copycats.
  3. Open the app and choose to import an existing wallet.
  4. Sign in with the same Google, Apple or Telegram account and password, or type in your 12 word recovery phrase.
  5. Set a password for the app and turn on your phone’s biometric unlock if you want faster access.
If you used social login, MetaMask says wallets you import on one device sync to your other devices that use the same social account. With a recovery phrase wallet, anything you imported separately by private key needs to be imported again on the new device.

​
Is the MetaMask Wallet Extension Safe? Benefits and Custody Model

The MetaMask wallet extension gives you full control of your keys, which is its biggest strength and its biggest responsibility. MetaMask adds scam warnings and transaction checks, but no wallet is risk free, and your own habits around the recovery phrase and links matter most.

​
What you get

  • You hold the keys: MetaMask can’t freeze, move or access your funds.
  • Several ecosystems in one place: EVM networks, Solana, Bitcoin and more under one account.
  • Wide dApp support: the extension is a common option on DeFi, NFT and Web3 sites.
  • Security alerts: MetaMask’s alerts, developed with the security firm Blockaid, flag known malicious sites and risky transactions before you sign.
  • Address poisoning detection: warnings when a recipient looks like a lookalike of an address you’ve used, now on both the extension and mobile.
  • Added Protection: announced in September 2026, it automatically reverts transactions that don’t match their preview, starting on the extension first.
Some of these protections are new and still rolling out, so features and the networks they cover may change. Keep the extension updated to get them.

​
FAQs

​
Is the MetaMask extension free to download?

Yes, installing the MetaMask extension from the official site and browser stores costs nothing. You’ll still pay network fees (gas) when you send transactions, and in app features like swaps can include their own fees, which MetaMask shows before you confirm.

​
Which browsers support the MetaMask wallet extension?

MetaMask’s help center lists Google Chrome, Mozilla Firefox, Microsoft Edge and Brave. Safari isn’t on that list, so on a Mac you’d use one of the supported browsers or the MetaMask mobile app instead.

​
Can I use the same MetaMask wallet on my phone and laptop?

Yes. Import the same Secret Recovery Phrase on each device, or sign in with the same Google, Apple or Telegram account and password if you set up with social login. Accounts imported by private key need to be added again on each new device unless you’re using social login sync.

​
What happens if I forget my MetaMask password?

If you still have your Secret Recovery Phrase, you can restore the wallet and set a new password. If you lose both the phrase and the password, MetaMask can’t recover the wallet, because it’s self custodial.

​
Does MetaMask support Bitcoin and Solana now?

Yes. Solana addresses arrived first, and native Bitcoin support followed in December 2025 using native SegWit addresses. Both sit inside your multichain account alongside your EVM address.

​
How do I spot a fake MetaMask extension?

Only install from links on metamask.io or the official browser store listings it sends you to. Watch for misspelled names, unusual publishers and ads at the top of search results, and remember that real MetaMask support never asks for your recovery phrase.

​
Conclusion

The MetaMask wallet extension is still one of the easiest ways to use Web3 apps from a desktop browser, and multichain accounts make it more practical now that it covers Solana, Bitcoin and other networks alongside Ethereum. Installing it takes a couple of minutes if you start from metamask.io and your browser’s official store.
