Regen Pass
A POAP platform that transforms event participation with AR, AI, geo-fencing, and cross-chain minting via Chainlink CCIP.
The problem Regen Pass solves
RegenPass revolutionizes event attendance by providing verifiable, interactive POAPs using AI-driven booth recognition and seamless blockchain minting. It enhances engagement, reduces fraud, and makes event participation provable and rewarding.
User Interaction and Data Flow
- User arrives at an event and is geo-verified to ensure they are within the designated event zone.
- The user scans a booth with their mobile camera.
- The AI agent analyzes booth banners, determines the blockchain, and provides a minting transaction builder.
- Augmented reality (AR) overlays interactive digital assets related to the event, enriching user engagement.
- The user confirms minting, and the transaction is executed on the correct chain via CCIP.
- The POAP is issued and displayed in the user’s wallet in real-time.
- The user is added to a leaderboard standing, where lucky winners can receive exclusive event-specific perks.
The project architecture and development process
- Frontend: Mobile-first web interface with camera integration.
- Backend: AI-powered booth recognition, geo-fencing, and event verification.
- Smart Contracts: Deployed on Base Sepolia & Ethereum Sepolia, supporting both direct and cross-chain minting.
- Cross-Chain Execution: Chainlink CCIP for seamless cross-chain POAP minting.
Product Integrations
- Chainlink CCIP: Enables cross-chain minting.
- Geo-Location Services: Ensures attendees are within the event area before minting.
- AI Image Processing: Booth recognition for automatic chain assignment.
- Augmented Reality (AR): Enhances POAP collection with interactive overlays.
- Block Explorers: Transaction tracking on Base and Ethereum Sepolia.
- Leaderboard System: Tracks attendees who minted POAPs, allowing event organizers to reward top participants with perks.
- Chainlink VRF: Ensures fair and tamper-proof random selection of winners for event-based rewards.
Key differentiators and uniqueness of the project
- AI-powered booth recognition: Automates blockchain selection for minting.
- Seamless AR integration: Enhances the POAP collection experience with interactive visuals.
- Geo-fencing verification: Ensures only attendees in designated areas can mint POAPs.
- Cross-chain POAPs: No manual selection; CCIP routes transactions automatically.
- Real-time minting confirmation: Users get immediate POAP verification.
- Leaderboard standing & event perks: Adds gamification, rewarding users who engage the most.
Trade-offs and shortcuts while building
- AI Optimization: Initial AI model is basic; future updates will improve accuracy.
- CCIP Simulation: Testing utilized CCIPLocalSimulatorFork before mainnet deployment.
- Mobile-first Approach: Desktop UI is secondary and will be optimized post-launch.
Additional Features
During the BUIDLathon, we:
- Enhanced the AI agent to suggest optimized gas fees for transactions.
- Enabled support for direct minting beyond Arbitrum Sepolia.
- Implemented on-chain storage of event metadata for transparency.
- Added geo-fencing validation to restrict POAP minting to event attendees.
- Integrated AR overlays to provide a dynamic and engaging experience.
- Introduced a leaderboard system where POAP minters can qualify for event-specific rewards and perks.
