What is the MetaMask app?

The MetaMask app is a non-custodial crypto wallet and Web3 browser. It securely stores your private keys on your device and provides an intuitive interface to send, receive, and swap tokens.

It supports Ethereum and EVM-compatible networks like Polygon, BNB Chain, and Avalanche, with easy network switching and customization.

The app integrates a secure browser for connecting to dApps, and each connection requests explicit permission. With the MetaMask app, you can monitor balances, review gas fees, manage NFTs, and sign onchain messages safely.

Frequently Asked Questions about MetaMask app

Is the MetaMask app safe to use?

The MetaMask app is designed with strong security practices: local key storage, biometric locks, phishing detection, and clear signing. However, safety also depends on you. Protect your secret recovery phrase, verify dApp URLs, and never approve transactions you don’t understand. For large balances, pair a hardware wallet.

What cryptocurrencies does the MetaMask app support?

The MetaMask app supports Ethereum and EVM-compatible networks, so you can hold ETH and ERC-20 tokens, plus NFTs (ERC-721/1155). By adding custom networks (e.g., Polygon, BNB Chain, Avalanche), you can manage tokens native to those chains as well. Non-EVM chains require separate wallets.

How do I recover my wallet in the MetaMask app?

Install the MetaMask app on a new device, choose “Import using Secret Recovery Phrase,” and enter your 12-word phrase in exact order. Set a new password and biometric lock. Never share your phrase with anyone—it grants full access to your funds.

Can I use the MetaMask app with hardware wallets?

Yes. The MetaMask app and browser extension support popular hardware wallets for added security. You sign transactions on the hardware device, while using MetaMask as the interface for dApps, balances, and network management.

What fees does the MetaMask app charge?

Network (gas) fees go to validators/miners, not to MetaMask. If you use built-in swaps or certain on-ramp/off-ramp services, there may be a service fee, which is displayed before you confirm. You can customize gas settings to balance cost and speed.

How do I add a new network in the MetaMask app?

In Settings, go to Networks and tap “Add Network.” Enter the RPC URL, chain ID, symbol, and block explorer. Many popular EVM networks offer one-tap adds from their official docs. Always verify details to avoid phishing or misconfiguration.

Why is my transaction pending in the MetaMask app?

Congestion or low gas can cause delays. Try speeding up the transaction by increasing gas, or cancel if it’s safe to do so. Ensure you’re on the correct network and that your nonce settings are not conflicting with previous pending transactions.
