1. What is MetaMask in 2025?

MetaMask started as an Ethereum browser extension and mobile wallet. In 2024–2025 it matured into a multi-chain asset manager: extension + mobile app + richer dApp integrations and a multichain API that lets dApps interact with multiple networks without forcing constant network switching. MetaMask’s official reports and market trackers place monthly active users in the tens of millions, confirming its central role in Web3 onboarding.

• Runs as a browser extension (Chrome/Firefox/Edge) and mobile app.
• Supports swaps, connected dApps, and multichain interaction via the Multichain API.
• Works with hardware wallets (Ledger/Trezor) for secure custody.

2. How to Install & Create a MetaMask Wallet

Follow these steps to install MetaMask safely on desktop or mobile.

1. Download from official source: Go to metamask.io and choose the correct extension or mobile app. Avoid third-party links.
2. Create a new wallet: Click “Create a Wallet”, set a strong password, and follow on-screen prompts.
3. Secure your seed phrase: MetaMask will show a 12- or 24-word seed phrase. Write it down on paper and store it securely offline.
4. Optional — Connect a hardware wallet: Later you can add a Ledger or Trezor account to MetaMask for cold key signing.

If you lose your seed phrase, you lose access to funds — MetaMask support cannot recover it for you.

3. Security Setup: Seed Phrase, 2FA, Hardware

Security is the most important step. Follow these practical measures:

• Never share your seed phrase — treat it like cash.
• Use a hardware wallet (Ledger/Trezor) for large balances; connect it to MetaMask to sign transactions without exposing private keys.
• Enable anti-phishing features and confirm domain names before approving transactions.
• Keep software updated: browser, MetaMask extension/app, and Ledger firmware.

4. Adding Funds: Fiat, Crypto & Layer-2

You can fund MetaMask using multiple methods depending on region and preferences.

• Buy on an exchange: Purchase ETH or stablecoins on a regulated exchange and withdraw to your MetaMask address.
• On-ramp providers: MetaMask integrates third-party on-ramps (MoonPay, Transak) for direct card purchases.
• Layer-2 networks: To save fees, use layer-2 solutions (zkSync, Arbitrum, Optimism) and bridge assets before using dApps; MetaMask supports L2s natively.

5. Using MetaMask with DeFi & NFTs

MetaMask is the standard wallet for interacting with most DeFi apps and NFT marketplaces.

1. Connect to the dApp: Click “Connect Wallet” on the dApp and choose MetaMask.
2. Review permissions: Check which contracts request allowances — avoid unlimited approvals where possible.
3. Use Gas Estimators & L2s: For cheaper transactions, prefer Layer-2s or schedule transactions during lower gas periods.
4. Track assets: Add custom tokens by contract address in MetaMask to view balances.

6. Tips to Save Fees & Best Practices

Small habits reduce risk and costs:

• Use limit orders on exchanges and avoid impulsive swaps with high slippage.
• Bridge assets in batches rather than frequent small transfers.
• Use hardware wallets for signing high-value transactions.
• Double-check recipient addresses (QR codes or copy-paste + checksum verification).
