EduFund Web3 Crowdfunding Platform

EduFund is a decentralized, 100% on-chain crowdfunding protocol and web platform built on the EDU Chain. It reimagines educational funding by replacing opaque fundraising campaigns with verifiable milestone-based fund escrows, community cryptographic voting, and automated smart-contract disbursements.

1. Problem & Mission

Traditional crowdfunding platforms suffer from high platform fees (5–10%), lack of post-funding accountability, and fraudulent campaigns where creators withdraw capital without delivering promised educational deliverables.

EduFund solves this by anchoring every donation in a trustless smart contract where:

• Funds are locked in escrow and released strictly in milestones.
• Donors vote on-chain with their proportional share weights to approve proof-of-work before milestone payouts unlock.
• Platform fees are slashed to near-zero via EVM layer execution on EDU Chain.

2. Core Protocol Features

• Milestone-Based Fund Escrow: Campaign creators divide targets into verifiable milestones. Funds remain timelocked until deliverables are uploaded and audited by backers.
• On-Chain Governance & Voting: Each backer receives quadratic or token-weighted voting power proportional to their contribution, preventing unilateral withdrawals.
• Automated Refund Trigger: If milestone deadlines expire without satisfactory proof or community approval, smart contract refund logic allows donors to reclaim remaining balances trustlessly.
• Live on EDU Chain: Deployed natively on the EDU Chain ecosystem, leveraging sub-cent transaction fees and fast finality.

3. Technology Stack

• Smart Contracts: Solidity (OpenZeppelin security standards, Hardhat testing environment)
• Frontend & UX: Next.js (App Router), React 19, TypeScript, Tailwind CSS
• Web3 Integration: Ethers.js, Wagmi, RainbowKit wallet connectors
• Hosting & CI/CD: Vercel deployment with automated Git pushes

4. Key Engineering Achievements

• Developed gas-optimized Solidity contracts reducing campaign creation gas costs by over 35% using storage packing and immutable variables.
• Implemented responsive Web3 state synchronizers that detect wallet account switches, network changes, and transaction confirmations in real-time.
• Delivered a live public demo deployed on EDU Chain testnet with comprehensive milestone lifecycle simulation.
