What Is MetaMask?

MetaMask is a non-custodial Web3 wallet launched in 2016 by ConsenSys, now serving over 21 million users. Initially designed for Ethereum, it supports EVM-compatible chains (e.g., Polygon, Arbitrum) and facilitates interactions with DApps like Uniswap and Compound. Available as a browser extension (Chrome, Firefox, Brave) and mobile app (iOS/Android), it offers:

• Secure private key storage
• Token swaps via integrated DEX aggregators
• Portfolio tracking
• Fiat-to-crypto purchases

Key Features

1. Web3 Wallet Functionality:

   • Connects seamlessly to DApps for trading, staking, and gaming.
   • Supports ERC-20, BEP-20, and other EVM-based tokens.

2. Multi-Chain Support:

   • Manually add networks like Avalanche or Polygon via custom RPC settings.

3. MetaMask Swaps:

   • Compares rates across decentralized exchanges (e.g., Uniswap, SushiSwap) for optimal pricing.

Security Analysis

Is MetaMask Safe?

• Non-Custodial: Users control private keys; funds aren’t held by MetaMask.
• Encryption: Data is stored locally and encrypted with a password.
• Recovery Phrase: 12-word backup phrase (store offline; never share!).

⚠️ Risks:

• Hot wallet vulnerability (internet-connected).
• Phishing scams targeting seed phrases.

Best Practices:

• Use with a hardware wallet (Ledger/Trezor) for added security.
• Enable two-factor authentication (2FA) where possible.
