Game Exchange QR - Marketplace Prototype - Sell Project

Game Exchange QR is a pre-launch digital-game marketplace prototype offered as a source-code project for a technical buyer to develop further. The responsive demo includes a fictional game catalog, search, genre filters, price sorting, saved games, sample seller listings and pricing, QR handoffs, buyer confirmation, sample libraries, transfer history, and receipts. QR links expire after ten minutes and support revocation and protection against repeat claims. The portable evaluation edition uses React, TypeScript/JavaScript, Node.js 24+, and SQLite. Prebuilt frontend assets are included, so buyers can run the local demo without API keys or access to the seller’s hosting account. Seller and buyer roles are simulated within sample-data sandboxes. This is a development prototype. No revenue, paying customers, verified traffic, or publisher partnerships are claimed. Real game-license transfers, independent buyer/seller accounts, live payments, seller payouts, refunds, and production operations remain unfinished. A live marketplace would require publisher/platform permission and an actual license-transfer integration. Included: current portable source code, custom interface, fictional SVG concept artwork, SQL schema, local demo, transfer tests, and setup documentation. Third-party components retain their existing licenses. Excluded: game binaries or licenses, publisher agreements, customer data, domain registrations, trademark rights, and personal, hosting, or payment accounts. The project was developed with AI assistance. “Replay” is a provisional label in the demo; no rights to replay.com or an existing Replay brand are included. Final price, transfer scope, exclusivity, and any transition support are subject to agreement. Further development and ongoing support are not included unless separately agreed.
