Eventverse is a decentralized, blockchain-powered event ticketing platform designed to eliminate fraud, opaque resale markets, and inefficient event access systems.
Built and deployed on Mantle Network, an Ethereum-aligned Layer 2, Eventverse enables event organizers to issue tickets as NFT-based digital assets, ensuring secure ticket purchases, transparent resales, and seamless QR-code-based on-chain verification.
By leveraging Mantle’s low-cost execution, EVM compatibility, and Ethereum security, Eventverse delivers a scalable, trust-minimized ticketing experience for both organizers and attendees.
- Event organizers mint tamper-proof NFT tickets containing event metadata.
- Tickets are fully on-chain and verifiable on Mantle.
- Ownership transfers are transparent, immutable, and trustless
- Intelligent chatbot to guide users through the Eventverse platform.
- Helps with ticket purchases, wallet connections, event creation, and NFT management.
- Provides step-by-step explanations for blockchain interactions.
- Accessible via a floating UI across the platform.
- Each NFT ticket is mapped to a unique QR code.
- QR scans verify ticket ownership directly on-chain via Mantle RPC.
- Prevents counterfeit tickets, duplicate scans, and replay attacks.
- All ticket actions (minting, transfers, resale) are executed on Mantle Network.
- Mantle’s low gas fees enable affordable, high-volume ticketing.
- Ethereum settlement guarantees long-term security and data integrity.
- Decentralized secondary marketplace enforced by smart contracts.
- Organizer-defined resale rules (price caps, royalties).
- Prevents scalping, fraud, and off-chain manipulation.
Eventverse is fully deployed on Mantle Sepolia Testnet, satisfying ecosystem deployment requirements.
