About this Project.
Hedera Crowdfunding Platform — Decentralized Fundraising System
The Hedera Crowdfunding Platform is a decentralized fundraising application built on Hedera Hashgraph that enables users to create crowdfunding campaigns and accept contributions using HBAR.
The platform uses Solidity smart contracts through the Hedera Smart Contract Service to manage campaign goals, contributions, deadlines, fund release, and refund workflows. Campaign activity and transaction history can be tracked through a React-based dashboard, while MongoDB provides off-chain storage for application data.
Users can connect their Hedera wallets, create campaigns, contribute to active campaigns, and monitor funding progress. An administrative dashboard provides visibility into campaigns, contributions, transactions, and overall platform statistics.
The project includes a Node.js/Express backend, React frontend, Hedera SDK integration, HashConnect wallet connectivity, Solidity contracts, and Hardhat development tooling.
It is suitable for developers, blockchain researchers, Web3 teams, and students looking to explore decentralized crowdfunding and Hedera smart contract development.
Important: This project is intended for development, testing, and demonstration purposes. A professional smart-contract security audit should be completed before deploying the platform with real funds on Hedera Mainnet.
