MetaMask

MetaMask review: our verdict

MetaMask is the default wallet for Web3. If you want to use decentralized exchanges, lend and borrow, mint NFTs or explore new apps on Ethereum and compatible networks, MetaMask is the easiest place to start, and almost every app supports it. It's free and full-featured, but as a hot wallet it's more exposed to phishing and malware, so larger balances should be protected by connecting a hardware wallet.

• Hardware wallet integration: use MetaMask's interface while keys stay on a Ledger or Trezor.
• Snaps: extensions that add features and support for additional networks.

Security

MetaMask is a self-custody wallet: your keys are encrypted on your device and protected by your password, and your Secret Recovery Phrase is the master backup. MetaMask includes transaction simulations and security alerts that warn about known malicious sites and suspicious requests.

The biggest risks are user-side: fake MetaMask extensions and apps, phishing sites that ask for your recovery phrase, and malicious transactions that grant unlimited token approvals. To stay safe:

• Install MetaMask only from its official website or verified app store listing.
• Never share your recovery phrase; MetaMask support will never ask for it.
• Read every signature request, and revoke unused token approvals regularly.
• Keep only spending amounts in MetaMask and connect a hardware wallet for savings.

Fees

The wallet itself is free. You pay network gas fees on every transaction, which vary by network. MetaMask's swap and bridge features add a service fee, so compare with doing the same swap directly on a decentralized exchange if cost matters. Read crypto fees explained.

How to set up MetaMask

1. Download the extension or app from the official MetaMask website.
2. Create a new wallet and a strong password.
3. Write down your Secret Recovery Phrase offline and confirm it.
4. Add the networks you plan to use.
5. Optionally connect a hardware wallet for larger balances.
6. Fund your wallet from an exchange, choosing the correct network.

MetaMask alternatives

Who should use MetaMask?
