# Introduction **VeChain's Global Hackathon** focuses on leveraging AI-powered applications, x-2-earn incentives, with sustainability at the forefront of these rewards. Builders will create EVM smart contracts on Solidity to build decentralized applications (dApps) that address real-world challenges, showing potential for mass adoption by users and scalability. There are three available tracks: - Track 1: **Social Impact - Build for People** - Track 2: **Economic & Environmental Impact - Protect our Planet** - Track 3: **Ecosystem & Technical Innovation - Grow the VeChain Ecosystem** # Timeline **✅ Submissions open**: 22nd September (00:00 UTC +2) **🔚 Submissions close**: 5th October (23:59 UTC +2) # Deliverables **👨‍💻Project Team**: Team participants and team name (minimum 2 team members). **💡Project Idea**: Title and description of the application, explaining why blockchain and how they solve the problem. **🔬Functional Prototype**: A working demo of the application using a VeChain smart contract. **👾Code Repository**: A GitHub link with deployment instructions on the VeChainThor network. **🎬Video Presentation**: A maximum 5-minute video explaining the solution, use case, and technical implementation. **📖 Pitch Deck**: A summary of the project, problem addressed, and future roadmap. # Prize Breakdown - **Track 1:** $5000 (1st Place), $3,000 (2nd Place), $2,000 (3rd Place) - **Track 2:** $5000 (1st Place), $3,000 (2nd Place), $2,000 (3rd Place) - **Track 3:** $5000 (1st Place), $3,000 (2nd Place), $2,000 (3rd Place) Additional $2,000 in rewards for valuable feedback on the VeChain tooling utilized # Eligibility Open to all builders. # Judging criteria ### **Innovation and Creativity (25%)** - Your idea shows novel use of VeChain features to solve real-world problems. - You have used AI to provide added value to the user. - You have a clear idea of why blockchain is needed for your use case. ### **Technical Skills (25%)** - The design of your dapp demonstrates the ability to write code meant to be maintained  - Your dapp has Smooth UX and functionality - You have integrated B3TR as a reward mechanism within the app  - You have integrated VeWorld wallet support for seamless B3TR transactions  ### **Impact and Feasibility (25%)** - Your dapp shows potential to onboard hundreds of thousands of users. - You have been effective in addressing the targeted problem. - Your dapp is viable in the real world. ### **Business model  and Research (25%)** - Your documentation explaining the problem, solution, and impact is complete and compelling. - Your value proposition is agreeable. - You have a good idea of the roadmap and of how to turn the idea into a sustainable business. # Contact us Join the official **[Telegram Channel](https://t.me/+XdONRV7Gu1dlNDVi)** for questions and support.
