How to set up the MetaMask wallet (Extension & Mobile)

Getting started takes minutes. Always download from official sources and verify the publisher before installing.

On desktop browsers (Chrome, Firefox, Brave, Edge)

Go to the official extension store and install the MetaMask wallet extension.
Create a new wallet or import an existing one.
Securely record your Secret Recovery Phrase (seed phrase) offline. Never share it.
Set a strong password and enable additional security where available.
Pin the extension for quick access and lock your wallet when not in use.
Add funds by receiving from an exchange or using a fiat on-ramp partner.
Connect to a dApp and approve permissions thoughtfully before signing.

On iOS and Android

Download the MetaMask wallet app from the official App Store or Google Play.
Create or import a wallet with your Secret Recovery Phrase.
Enable biometrics (Face ID/Touch ID) for fast, secure unlocks.
Back up your seed phrase offline—consider multiple secure copies.
Use the in-app browser to explore dApps or connect via WalletConnect.

Tip: Test with small transactions first. Confirm addresses and network selections before sending larger amounts.

Security best practices for your MetaMask wallet

Security is shared responsibility. The MetaMask wallet gives you the tools—your habits keep them effective. Adopt these proven practices to protect your assets and identity.

🗝️ Protect your Secret Recovery Phrase: Store it offline (paper/steel). Never type it into websites, chats, or forms.
🔏 Use hardware wallets for high-value funds: Pair Ledger or Trezor with MetaMask for cold-key signing.
🧩 Verify extensions and URLs: Watch for look-alike domains and fake wallet popups.
🧠 Read transaction prompts: Check contract addresses, token symbols, and spending caps before you sign.
🛑 Avoid blind signing: Prefer human-readable signatures (EIP-712) when available.
📵 Separate devices/accounts: Keep a dedicated wallet for testing and use multiple accounts for permission hygiene.
🧹 Revoke approvals periodically: Use trusted tools to remove unused token allowances.

Remember: the MetaMask wallet is non-custodial. Only you can restore access with your seed phrase. MetaMask support will never ask for it. If a site or person does, it’s a scam.

Using the MetaMask wallet for DeFi, NFTs, and more

DeFi in one tap

Connect your MetaMask wallet to top DeFi protocols to lend, borrow, stake, and earn yield. Set gas strategies, sign with confidence, and track your portfolio across chains. Built-in swaps help you compare quotes and execute trades directly from your wallet interface.

NFTs and digital collectibles

View supported NFTs inside your MetaMask wallet and connect to marketplaces to mint, buy, or list. Confirm the correct network, contract address, and collection details before transacting. For rare items, consider signing via a hardware wallet for extra assurance.

Payments and transfers

Send and receive tokens on Ethereum and compatible networks.
Customize gas fees for speed or savings.
Label addresses to avoid mistakes and reduce friction.

Networks, gas, and fees in the MetaMask wallet

By default, the MetaMask wallet connects to Ethereum Mainnet. You can add EVM-compatible networks like Polygon, Arbitrum, Optimism, Base, and BNB Chain. Gas fees are network fees paid to validators—not to MetaMask. L2 networks typically offer faster, cheaper transactions while inheriting Ethereum’s security model.

➕ Add networks via official docs or trusted aggregators; confirm RPC URLs.
🔄 Bridge assets with reputable bridges when moving funds across chains.
⏱️ Save gas by avoiding peak times and using EIP-1559 fee controls.

Frequently Asked Questions about MetaMask wallet

What is the MetaMask wallet and how does it work?

The MetaMask wallet is a non-custodial crypto wallet for Ethereum and EVM networks. It stores your private keys locally, lets you sign transactions, and connects to dApps. You control your seed phrase, so only you can restore access. Use the browser extension or mobile app to send, receive, swap tokens, and manage NFTs.

Is the MetaMask wallet safe?

Yes—when used correctly. The MetaMask wallet is non-custodial, so your security depends on protecting your seed phrase, passwords, and devices. Enhance safety with hardware wallets, biometrics on mobile, verified URLs, and careful review of every signature. Never share your Secret Recovery Phrase with anyone.

How do I add networks like Polygon or Arbitrum to my MetaMask wallet?

Open Settings > Networks > Add Network and enter the official RPC details. Many dApps suggest networks automatically. Always verify the network name, RPC URL, chain ID, currency symbol, and block explorer URL from trusted documentation before saving.

What fees does the MetaMask wallet charge?

Network gas fees go to validators, not MetaMask. If you use built-in swaps or on-ramp partners, service fees may apply and are shown before you confirm. You can adjust gas for speed/cost trade-offs on supported networks.

Can I connect a hardware wallet to the MetaMask wallet?

Yes. You can connect supported hardware wallets (e.g., Ledger and Trezor) to sign transactions with offline keys while using the MetaMask interface. This adds a powerful layer of security for larger balances and high-value NFTs.

How do I restore my MetaMask wallet on a new device?

Install MetaMask, select “Import,” and enter your 12-word Secret Recovery Phrase in the correct order. Set a new password and enable security options. Your accounts and balances will sync from the blockchain; tokens or NFTs may require re-adding contract addresses to appear.

Why aren’t my tokens showing in the MetaMask wallet?

Make sure you’re on the correct network and add the token contract address manually if needed. Some assets don’t auto-populate. Use a trusted block explorer to confirm you hold the token at your wallet address and then add it to your asset list.
