FundChain — Decentralized Crowdfunding Platform
FundChain is a full-stack decentralized crowdfunding protocol built on Ethereum. Unlike traditional platforms like Kickstarter, FundChain gives backers real power — they vote on how funds are spent, funds are released milestone by milestone, and refunds are automatic if a campaign goal isn't reached. No middleman. No trust required.
The core insight: crowdfunding fails when backers have no control after donating. FundChain solves this with on-chain DAO governance.
— 4 smart contracts in Solidity 0.8.20: FundChain V2, FundChainDAO, FundChainNFT, FundChainMultiToken
— DAO governance: backers vote on spending proposals with voting power proportional to donation amount
— Milestone-based fund release: campaign owners cannot withdraw all funds at once
— Multi-token donations: accept ETH, USDC, and USDT in one campaign
— NFT badges for donors: Bronze (0.01 ETH), Silver (0.05 ETH), Gold (0.10 ETH) — ERC-721
— IPFS image storage via Pinata for fully decentralized campaign media
— Analytics dashboard with real on-chain transaction data via Etherscan API
— Full Next.js 14 frontend with dark/light mode, mobile responsive, countdown timers
