What is MetaMask?
MetaMask, often referred to as the "Fox Wallet," is an open-source decentralized cryptocurrency wallet renowned for its user-friendly interface and robust functionality. Created by ConsenSys—a blockchain software company specializing in Ethereum-based tools and infrastructure—MetaMask allows seamless interaction with Ethereum's blockchain ecosystem.
Key features include:
- Decentralized Transactions: Buy, sell, store, and send tokens without intermediaries.
- DApp Integration: Access decentralized applications (DApps) directly via browsers like Chrome, Firefox, and Brave.
- Multi-Platform Support: Available as browser extensions (Chrome, Edge, etc.) and mobile apps (iOS/Android).

Step 2: Create or Import a Wallet
- New Users: Click Create a Wallet and follow the prompts.
- Existing Users: Select Import Wallet and enter your 12-word recovery phrase.
Step 3: Set a Secure Password

Step 4: Safeguard Your Recovery Phrase
⚠️ Critical Security Notes:
