RegenPass is a next-generation POAP (Proof of Attendance Protocol) platform that transforms event participation into a dynamic, interactive digital experience. By combining geo-location, augmented reality (AR), AI-powered booth recognition, and cross-chain minting via CCIP/Chainlink, RegenPass enables attendees to collect unique, branded POAPs that serve as verifiable proof of their participation—minted on the ideal blockchain network based on the event booth detected.

• Deployment:

  • Base Sepolia: The primary contract is deployed here. An agent initiates cross-chain mint requests from this chain using Image Processing.
  • Ethereum Sepolia & Arbitrum Sepolia: Destination contracts are deployed on these chains to receive and process cross-chain minting requests.

• Direct Minting:
  The direct mint function no longer has the restriction that previously limited it to Arbitrum Sepolia. This change enables direct minting on any chain, including Base Sepolia.

• Cross-Chain Minting:
  The crossChainMint function is now called on Base Sepolia. Once invoked, the Chainlink CCIP router (simulated via the CCIPLocalSimulatorFork) routes the mint request to the destination chain where the NFT is minted.

• Seamless Onboarding & Geo-Verification
  Quickly register and verify attendance using geo-location to ensure participants are within designated event zones.

• Immersive AR Experience
  Engage with dynamic AR assets as soon as the camera opens, enhancing the in-person experience with interactive digital overlays.

• AI-Powered Booth Recognition & Agent Flow
  As soon as the camera activates, the integrated AI agent begins scanning the image. This real-time analysis not only recognizes booth banners and identifies the associated chain (e.g., Chainlink or Base) but also dynamically provides the client with a tailored transaction builder. This ensures that the correct minting process is initiated based on the detected chain booth.

• Cross-Chain POAP Minting via CCIP/Chainlink
  Initiate a mint function on Sepolia that leverages CCIP to direct the actual minting on the target blockchain as determined by the recognized booth, ensuring optimal cross-chain interoperability.

• Secure, Real-Time Transaction & Wallet Updates
  Conduct secure on-chain transactions with immediate updates to the user’s digital wallet, providing verifiable proof of attendance in real time.

• Robust Error Handling & User Feedback
  Offer clear prompts for re-scanning or retrying in cases of unrecognized inputs or transaction failures, ensuring a smooth user experience.

• Event Attendance Verification
  Provide a reliable and engaging method for participants to prove their attendance at events, conferences, and expos.

• Brand Activation & Engagement
  Allow brands to create custom POAP experiences (e.g., Chainlink or Base-themed) that boost interaction and leave lasting digital impressions.

• Community Building & Gamification
  Foster community spirit and friendly competition by enabling users to collect, display, and share their unique POAPs across social channels.

• Marketing & Promotional Campaigns
  Enhance event marketing by offering exclusive, collectible digital rewards that can double as discount coupons or access passes for future events.
