Problem Statement

🏟️ Project DescriptiontrueFanz is a decentralized ticketing platform built on the Chiliz Spicy Testnet. • Teams: Each sports team has an official wallet that issues match tickets as NFTs.• Ticket Sales: Tickets are sold directly by the team wallet to fans, using CHZ as the only payment currency. • Transparency & Security: By minting tickets as NFTs on Chiliz, fans are guaranteed authenticity, ownership, and transferability — eliminating counterfeits and cutting out resellers. • Stadium Entry: Fans present a QR code linked to their NFT at the stadium gate. The code is scanned and verified against the blockchain to ensure ownership before entry.⸻🌟 Key Features 1. CHZ-Only Payments → Fans pay only in CHZ, the native Chiliz currency.2. Direct Sales Only → Tickets can be sold only by teams. No scalpers, no third parties. 3. NFT Ticketing → Each ticket is an ERC-721 NFT, secure and verifiable. 4. Decentralized Metadata → Stored on IPFS/Pinata, fetched dynamically by the frontend. 5. Seamless Stadium Entry → QR code scanning ensures tickets are real and owned by the fan.

Solution

⸻⚙️ How It’s Made • Frontend Built with Next.js + TypeScript, styled with Tailwind CSS.• Privy handles wallet authentication (connects fans and teams securely). • Marketplace UI lets fans browse available tickets and purchase directly in CHZ. • Tickets appear under “My Tickets” and are linked to NFT metadata. • Smart Contracts Written in Solidity and deployed with Hardhat on Chiliz Spicy. • PSGTicketNFT.sol (ERC-721) • Mints NFT tickets for matches. • Minting restricted to Team Wallet only. • Metadata (match, date, venue) stored on IPFS. • FixedPriceSale.sol • Handles ticket listing and direct purchase in CHZ. • Only Team Wallet can list tickets. • Fans purchase directly via CHZ payments — no peer-to-peer resale allowed. • Storage (Pinata/IPFS) • Ticket metadata (match info, venue, date, seat image, QR info) is pinned to IPFS via Pinata. • NFT tokenURI points to IPFS CID. • Frontend fetches and renders ticket info from IPFS gateway. • Ticket Verification Flow 1. Fan shows QR code at the stadium gate. 2. Scanner fetches NFT metadata + checks ownerOf(tokenId) on Chiliz Spicy. 3. If fan wallet matches ownership, access granted.
