MetaMask, commonly known as the "Fox Wallet," is one of the most widely recognized decentralized cryptocurrency wallets in the blockchain space. Developed by ConsenSys—a leading blockchain software company focused on Ethereum-based tools and infrastructure—MetaMask enables seamless interaction with the Ethereum ecosystem and beyond. It allows users to store, send, and receive digital assets, connect to decentralized applications (DApps), and manage multiple blockchain networks—all directly from a browser extension or mobile app.
Whether you're stepping into DeFi, NFTs, or GameFi, MetaMask is often the go-to wallet for beginners and experienced users alike. This guide walks you through setting up your MetaMask wallet, securing your assets, adding popular EVM-compatible networks like Binance Smart Chain (BSC), Polygon, and Fantom, and understanding its core features.
How to Set Up MetaMask on Chrome
Setting up MetaMask is straightforward and can be completed in just a few steps using the Chrome browser.
Step 1: Install the Extension

Step 2: Create or Import a Wallet
If you’re new to MetaMask, select “Create a Wallet.” If you already have an existing wallet, choose “Import Wallet” and enter your 12-word recovery phrase.
Step 3: Set a Strong Password
Create a unique password that will be used to unlock your wallet each time you access it. Note: This password does not recover your wallet if lost—only your recovery phrase can do that.
Step 4: Secure Your Recovery Phrase (Critical!)
After setting your password, MetaMask will display a 12-word recovery phrase (also known as a seed phrase). This is the most important part of your setup:
- The recovery phrase acts as your private key—it proves ownership of the wallet.
- Anyone who gains access to this phrase can transfer all your funds.
- Write it down on paper and store it in a secure location like a safe.
- Never take a screenshot, save it digitally, or share it with anyone.
- Even MetaMask support cannot recover your phrase.
This phrase is your sole means of restoring access across devices. Without it, you lose access permanently.
Step 5: Confirm Your Recovery Phrase
To ensure you’ve recorded it correctly, MetaMask will ask you to re-enter the words in order. Once confirmed, your wallet is ready to use.
