Cyberpunk marketplace with crypto commerce and creator tools
PURPLE PROTOCOL is a full-stack cyberpunk web application combining a game experience with a creator marketplace and crypto-native commerce infrastructure. The platform includes authenticated accounts, creator profiles, digital products, protected digital delivery, server-authoritative orders, payment processing, an internal financial ledger, creator balances, wallet verification, withdrawals, admin operations and audit trails. The commerce layer is provider-agnostic and currently includes NOWPayments integration for USDT/TRC20 checkout, signed webhook/IPN validation, server-side payment status verification, payment reconciliation and an internal ledger designed to keep financial state authoritative on the server. Creators can create profiles, publish digital products and receive balances from completed sales. Buyers can purchase digital products through the marketplace and receive protected access after payment settlement. The system also includes safeguards for duplicate orders, checkout idempotency, ambiguous payment states, payout submission races and reconciliation workflows. Technology includes Node.js, Express, SQLite, JavaScript, HTML/CSS, Docker and Caddy, with TRON wallet signature verification for the selected USDT TRC20 payout rail.
