🃏 [FOR SALE] Durak Crypto — Real-Money Card Game Platform (USDT/TRON) $17k 💰

🃏 Durak Crypto — Custom-Built Real-Money Card Game Platform (USDT/TRON)

Selling a production-ready, custom-built real-money "Durak" card game platform for crypto (USDT TRC-20 on Tron). This is not a re-skinned white-label casino script — it's a bespoke platform built from scratch with a full game engine, working on-chain money layer, real-time multiplayer, and a Telegram Mini App.

⚙️ What it is

🎮 Custom Durak game engine — server-authoritative, full ruleset (attack/defense/throw-in/trump logic), 2–6 player tables
💸 Working on-chain money loop — real USDT deposits/withdrawals already processed end-to-end on Tron (HD wallets, BIP39, deposit monitoring, idempotent tx handling)
🔌 Real-time multiplayer via Socket.io, reconnect support, private rooms
🎨 Polished dark-casino UI, mobile swipe-to-play, 20-language i18n, PWA + Telegram Mini App
🛠️ Admin panel (KPI dashboards, manual withdrawal approval, user management) + built-in support ticket system
🔗 Referral system with rake-share payouts

🧱 Tech stack
NestJS 11 + Next.js 14 (TypeScript), PostgreSQL, Redis, BullMQ, TronWeb, Socket.io, Docker Compose.

🔒 Security
Full internal audit completed. All Critical/High findings fixed and tested — including a critical card-forgery vector, now fully server-side validated. Money path audited clean: atomic balance guards, idempotent deposits, double-refund protection. 252 backend tests passing, clean builds. Only minor non-money-path hardening items remain in backlog (documented).
