描述
The Counter Smart Contract is a simple Solidity-based blockchain project that allows users to increment or decrement a stored number on-chain.
It demonstrates core concepts of smart contract development, including state variables, functions, and user interaction, making it ideal for beginners learning how to manage and manipulate data on the Ethereum blockchain.
This contract ensures safe operations by preventing the counter from going below zero, providing a practical example of using require statements for validation.
It can be deployed on any Ethereum-compatible network and interacted with through Remix IDE or integrated into a DApp frontend using Web3.js or Ethers.js.
