MetaMask Wallet — Your Web3 Identity

MetaMask Wallet provides a browser-integrated, non-custodial wallet for Ethereum and EVM-compatible networks. This guide covers installation, secure setup, dApp connectivity, developer integration, troubleshooting and SEO-optimized content for the phrase MetaMask Wallet.

What is MetaMask Wallet?

MetaMask Wallet is a browser extension and mobile app that acts as a bridge between regular web browsers and blockchain networks. It enables users to manage keys, sign transactions, and interact with decentralized apps. Being non-custodial, users retain full control over private keys and recovery phrases.

Installation & Setup

To install MetaMask Wallet:

  1. Visit the official MetaMask website and select your platform: browser extension or mobile app.
  2. Install the extension from the official store and open it by clicking the fox icon.
  3. Create a new wallet or import existing one using your 12-word seed phrase. Securely back up the seed phrase offline.
  4. Set a strong password for local unlocking and enable biometric/security options on mobile.

Advanced Features

Network Management

Add custom RPCs and switch between chains seamlessly.

Token Swaps

Swap tokens directly inside the wallet with integrated routing and gas estimation.

Hardware Wallet Support

Connect Ledger or Trezor for cold-key signing and enhanced security.

Privacy & Permissions

Manage dApp permissions and clear granted access to protect your assets.

Security Best Practices

  • Never share your seed phrase or private key; treat it like legal tender.
  • Use hardware wallets for large balances and enable local biometric unlock where possible.
  • Review transaction details (value, recipient, gas) before confirming.
  • Revoke dApp permissions and monitor connected sites regularly.

Developer Integration

Developers integrate with MetaMask using the provider injected at window.ethereum. Libraries like Ethers.js and Web3.js support account requests, signing messages/transactions, and listening to events. Use EIP-1102/EIP-1193 patterns to request account access and handle network changes gracefully.

Troubleshooting

  • If MetaMask does not load, clear extension cache or reinstall.
  • For missing tokens, add the token contract manually via the token tab.
  • Failed transactions often relate to insufficient gas or incorrect nonce — review settings and retry with correct gas.
