How to use MetaMask on Google Chrome? (Browser Extension)

Installation Process

1. Navigate to the Chrome Web Store and search for 'MetaMask'.

2. Locate the official MetaMask extension published by MetaMask.io.

3. Click the 'Add to Chrome' button and confirm the permission prompt.

4. Once installed, a fox-shaped icon appears in the top-right corner of the browser window.

5. Click the icon and select 'Get Started' to begin setup.

Wallet Creation and Recovery

1. Choose 'Create a Wallet' when prompted during first launch.

2. Enter a strong password and agree to the terms — this password unlocks the extension locally.

3. Write down the 12-word secret recovery phrase on physical paper — never store it digitally.

4. Confirm the recovery phrase by selecting words in correct order as instructed.

5. After confirmation, the wallet is initialized and ready for use on Ethereum-compatible networks.

Network Configuration

1. Click the network dropdown (default shows 'Ethereum Mainnet') beside the account balance.

2. Select 'Custom RPC' to add non-default chains like BNB Smart Chain or Polygon.

3. Input required fields: Network Name, New RPC URL, Chain ID, Currency Symbol, and Block Explorer URL.

4. Save the configuration — the new network appears in the list and becomes selectable.

5. Switch between networks instantly using the same dropdown menu without reloading pages.

Connecting to dApps

1. Visit a decentralized application such as Uniswap or OpenSea in Chrome.

2. Click the 'Connect Wallet' button on the dApp interface.

3. Choose MetaMask from the wallet connection modal.

4. Approve the connection request in the MetaMask popup — this grants read-only access to your public address.

5. Confirm transaction signatures directly in MetaMask when interacting with smart contracts.

Troubleshooting Common Issues

1. If the MetaMask icon does not appear after installation, restart Chrome completely.

2. If transactions remain pending, check gas price settings and consider increasing priority fee manually.

3. If balance displays zero despite confirmed on-chain activity, verify the selected network matches where assets reside.

4. If unable to import an existing wallet, ensure the 12-word phrase is entered exactly as recorded — case and spacing matter.

5. If connection fails with a dApp, disable ad blockers or privacy extensions that may interfere with injected web3 providers.

Frequently Asked Questions

Q1. Can I use the same MetaMask wallet across multiple browsers?Yes — restore it using the same 12-word recovery phrase in any supported browser extension.

Q2. Does MetaMask store my private keys on its servers?No — private keys are generated and stored only locally within your browser. MetaMask never transmits them externally.

Q3. Why does MetaMask ask for permission to 'read and change site data'?This permission enables injection of the web3 provider into websites, allowing secure interaction with blockchain protocols without exposing keys.

Q4. What happens if I forget my MetaMask password?You can still regain full access using the 12-word secret recovery phrase — no password reset option exists because the password only decrypts local storage.
