2. Setting Up Your Wallet

Click on the MetaMask icon and follow the instructions:

- Choose “Create a Wallet.”

- Set a strong password for security.

- You’ll be given a Secret Recovery Phrase (12 words). Write it down and store it in a safe place. This phrase is your backup key, if you lose it, you lose access to your wallet permanently.

- Confirm your recovery phrase to complete the setup.

Now, your MetaMask wallet is ready to use!

3. Adding Funds

To use your MetaMask wallet, you’ll need to add some crypto to it, usually Ethereum (ETH) or ERC-20 tokens.

You can add funds by:

- Transferring from another wallet

- Withdrawing from a centralized exchange (like Binance or Coinbase) to your MetaMask address

- Buying ETH directly through MetaMask with a debit or credit card (availability depends on your region)

Your wallet address always starts with “0x”, and you can copy it right from the extension.

4. Connecting to dApps

One of the best features of MetaMask Extension is that it allows you to connect and interact with dApps. Whether you're trading on a DEX, minting NFTs, or using a DeFi protocol, MetaMask makes the process seamless.

Just visit dApps' website, and it will prompt you to connect your wallet. Confirm the connection through the MetaMask pop-up, and you’re ready to go.

5. Swapping Tokens

MetaMask Extension has a built-in token swap feature that lets you exchange tokens without leaving the wallet. It gathers the best rates from various decentralized exchanges.

To swap:

- Open MetaMask and go to the “Swap” tab.

- Choose the tokens you want to trade.

- MetaMask will show you the best available rate.

- Confirm and approve the swap.

6. Switching Networks

Even though MetaMask was designed for Ethereum, it can also connect to other Ethereum Virtual Machine (EVM)-compatible blockchains like:

- Binance Smart Chain (BSC)

- Polygon

- Arbitrum

- Avalanche, and more

To add a new network:
