Features

Multi-Network Support

Supports Ethereum mainnet plus any EVM-compatible network. Add Polygon, Arbitrum, Optimism, BNB Chain, Avalanche, and custom networks in seconds.

Built-in Token Swap

Swap ERC-20 tokens directly within MetaMask using aggregated DEX liquidity. Convenient but charges a 0.875% fee — use Uniswap directly to avoid this.

Hardware Wallet Integration

Connect Ledger, Trezor, or GridPlus Lattice1 as a signing device. Your private keys stay on the hardware wallet while MetaMask provides the browser interface.

Mobile App

Full-featured iOS and Android app with WalletConnect support for mobile dApp interaction. Includes an in-app browser for dApps.

NFT Support

View, send, and interact with NFTs on Ethereum and EVM networks directly in MetaMask. Autodetects NFTs in your wallet.

MetaMask Snaps

Extend MetaMask with third-party plugins (Snaps) for additional functionality like non-EVM chains, security alerts, and custom features.

Security

MetaMask is a non-custodial wallet — ConsenSys/MetaMask never holds your private keys. Your keys are encrypted and stored locally in your browser or on your device. The main security risks are:

  • Phishing: Fake MetaMask websites trying to steal your seed phrase. Always download from metamask.io only.
  • Malicious dApps: Always review transaction details before signing. MetaMask shows what permissions you're granting.
  • Seed phrase exposure: If someone obtains your 12-word phrase, they can drain your wallet. Never photograph or store digitally.
  • Compromised device: Malware can extract MetaMask keys from an infected device. Hardware wallet integration mitigates this.

Security Best Practices

  • Use MetaMask with a Ledger or Trezor for holdings over $1,000
  • Never enter your seed phrase in any website or app
  • Enable the MetaMask security alerts feature
  • Use separate wallets for DeFi interaction and long-term storage
  • Regularly revoke unused token approvals on revoke.cash

Frequently Asked Questions

Is MetaMask safe to use?
MetaMask is safe if used correctly — never share your seed phrase, use a hardware wallet for large holdings, and only connect to trusted dApps. The main risks are phishing attacks and user errors, not MetaMask's software itself.
Is MetaMask free?
Yes. MetaMask is free to download and use. MetaMask charges no fees for storing or sending ETH. However, the built-in swap feature charges a 0.875% fee; you can avoid this by using external DEXs like Uniswap directly.
Can MetaMask hold Bitcoin?
Not natively. MetaMask is an Ethereum-based wallet. It supports Ethereum mainnet, all EVM-compatible chains (Polygon, BNB Chain, Arbitrum, etc.), and custom networks. For Bitcoin, you need a separate wallet like Ledger, Trezor, or BlueWallet.
How do I recover a MetaMask wallet?
Use your 12-word seed phrase (Secret Recovery Phrase) to restore your MetaMask wallet on any device. Never enter your seed phrase anywhere except the official MetaMask app during recovery — all seed phrase requests on websites are scams.
Should I use MetaMask with a hardware wallet?
Yes — this is best practice for significant holdings. You can connect Ledger or Trezor to MetaMask, using the hardware wallet as a signing device while MetaMask serves as the interface. Your keys stay on the hardware device.
What is MetaMask Portfolio?
MetaMask Portfolio (portfolio.metamask.io) is a dashboard for viewing all your assets across multiple wallets and networks. It also offers bridging, staking, and buying functionality.
