What is MetaMask?
MetaMask is a versatile crypto wallet available as a browser extension (Chrome, Firefox, Edge) and mobile app (iOS/Android). It enables interaction with Ethereum Virtual Machine (EVM)-compatible blockchains like Ethereum, Polygon, Avalanche, and Binance Smart Chain—ideal for DeFi protocols, NFT platforms, and token transactions.
Key Features:
- Non-Custodial Control: Users own their private keys (12-word recovery phrase).
- Multi-Chain Support: Switch between EVM networks seamlessly.
- Browser Integration: Direct access to dApps without full node downloads.
Step-by-Step Installation Guide
1. Download MetaMask
👉 Download the official MetaMask extension (Always verify the URL: metamask.io to avoid phishing).
2. Set Up Your Wallet
- Click "Create a Wallet" and set a strong password.
- Backup your 12-word recovery phrase—store it offline (never digitally).
- Confirm the phrase to complete setup.
Note: MetaMask may request data collection consent; this is optional.
Using MetaMask: Send/Receive Crypto
Receiving Funds
- Copy your public address (starts with
0x...) from MetaMask. - Share this address with senders or exchanges to deposit tokens.
Sending Funds
- Click "Send," paste the recipient’s address.
- Select the token/amount, adjust gas fees (higher fees = faster processing).
- Confirm the transaction.
Pro Tip: Use Polygon (MATIC) for low-cost transactions vs. Ethereum’s high gas fees.
Troubleshooting Missing Tokens
If tokens don’t appear:
- Check the blockchain explorer (e.g., Polygonscan) for transaction status.
- Verify the correct network—your address works across EVM chains, but funds are network-specific.
Manually add tokens:
- Go to "Import Tokens" in MetaMask.
- Paste the token’s contract address (found on explorers).
Security Best Practices
- Never share your recovery phrase or store it digitally.
- Use hardware wallets (Ledger/Trezor) for enhanced security—link them via "Connect Hardware Wallet" in MetaMask.
- Review smart contracts before approving transactions to avoid scams.

Cross-Chain Transfers
- Bridges: Use tools like Multichain to move assets between chains.
- Centralized Exchanges: Deposit/withdraw to the target network (e.g., ETH → Polygon via Binance).
- Caution: Ensure token compatibility (e.g., wBTC ≠ BTC on Ethereum).
