🛠️ CodeDuet React App (DApp)

• Vercel Live demo: coduet.vercel.app • Anchor Program: github.com/alisonborba/coduet

A decentralized application (dApp) built on Solana to connect developers seeking help with other developers ready to collaborate and earn.

Watch the demo

📌 Overview

CodeDuet is a Web3-powered platform that allows users to request developer help through paid job posts, match with potential helpers (bidders), and settle jobs via smart contract transactions on the Solana blockchain.

This repository contains the React + Next.js front-end of the project, which interacts with the Anchor smart contract deployed on Solana Devnet.

🚀 Features

  • ✍️ Create Help Post: Users can publish posts requesting assistance with coding tasks.
  • ❌ Cancel Posts: Publishers can cancel open posts; only the platform fee is retained.
  • 💰 Fee Management (5%): Platform fees are automatically deducted upon post creation or cancellation.
  • 📩 Apply for Jobs: Helpers can apply to posts as bidders.
  • ✅ Complete Contract: Once the helper completes the task, the publisher can release the funds.
  • 🔐 Full smart contract validation via Anchor framework.
  • 🎨 Responsive UI powered by Tailwind CSS.
