FundMesh

Overview

FundMesh is a decentralized crowdfunding DApp built on Ethereum. The platform introduces innovative trust mechanisms and milestone-based funding releases to create better alignment between project creators and backers.

Key Features

• Milestone-Based Funding: (WIP) Funds are released progressively as projects achieve community-approved milestones.
• Community Governance: Contributors vote on whether projects should receive their next funding tranche.
• NFT Rewards: Contributors earn commemorative NFTs for projects they've helped succeed.
• Full Transparency: All project funding and governance operates on-chain for complete transparency.
• No Platform Fees: Direct creator-to-backer funding without intermediaries.

Note: The milestone-based funding feature is currently a work-in-progress and under active development.

6. Run the client

   npm run dev
   

Visit http://localhost:3000 to see the application.

Smart Contract Architecture

• Project Contract: Core contract handling project creation, funding, and milestone progression
• ProjectFactory: Factory contract for deploying new Project instances
• ProjectNFT: ERC-721 implementation for reward NFTs

Testing

The project includes comprehensive tests covering all smart contract functionality:

npm test

Deployment

Deploying to Sepolia Testnet
