설명
CoffeeBean is a simple yet powerful Web3 DApp that lets users show appreciation by sending a virtual coffee (a small Ethereum tip) directly to the creator through the blockchain.
Built with Solidity, Hardhat, and Ethers.js, CoffeeBean demonstrates how smart contracts enable secure, transparent, and decentralized transactions without intermediaries. Users connect their MetaMask wallet, enter their name and message, and send ETH as a token of gratitude — all recorded immutably on the Ethereum blockchain.
This project serves as an excellent introduction to decentralized applications, showcasing wallet integration, smart contract deployment, and real-time blockchain interactions in a beginner-friendly way.
✨ Highlights:
Fully decentralized Ethereum tipping system
Smart contract built with Solidity
MetaMask wallet integration
Transparent transaction storage
