MetaMask Operations

MetaMask Setup​

1. Overview​

MetaMask is a widely used Web3 wallet that allows users and developers to interact with blockchain networks directly from their browser or mobile device. It provides a secure interface for managing keys, accounts, tokens, and decentralized applications (dApps).

  • Token Management: Add ERC-20/ERC-721 tokens manually or automatically
  • dApp Integration: Seamless integration with decentralized applications
