Building Smart Contract Using Solidity: Your Step-by-Step Guide

Prerequisites for Smart Contract Development

Before starting, ensure to have a few essential tools and a basic understanding of programming concepts.

• Basic Programming Knowledge: Familiarity with fundamental programming concepts such as variables, functions, and control structures is essential.
• Node.js and npm: These tools are necessary for managing the dependencies needed for smart contract development.
• MetaMask: A browser extension that allows interaction with the Ethereum blockchain.
• Remix IDE: An online integrated development environment specifically designed for writing, compiling, and deploying smart contracts.
