A pack-opening platform that combines real-time reward mechanics, crypto payments, and scalable backend infrastructure. Built for production deployment—not a proof-of-concept—with emphasis on performance, security, and operational flexibility.

This repository contains the frontend only.
It is published publicly so potential builders, clients, and collaborators can review the UI, product flows, and implementation quality. The full codebase—including the backend API, admin dashboard, payment webhooks, and database layer—is available on request. See Contact & Collaboration below.

The frontend expects a running backend API. Most screens will load, but login, payments, pack opens, and live updates require the backend from the full platform.

PackDraw (HypePack) delivers an instant, engaging unboxing experience where users purchase digital packs, open them in real time, and receive randomized rewards. The platform integrates cryptocurrency payments, persistent user accounts, transaction history, and an administrative layer for day-to-day operations.

The product sits at the intersection of gaming mechanics, digital collectibles, and seamless Web3 payments—a pattern that continues to drive strong user engagement when execution is fast, fair, and transparent.

1. Onboard — User creates an account and completes authentication.
2. Fund — User deposits via supported cryptocurrencies through NOWPayments.
3. Purchase — User selects and buys a pack; balance is debited atomically.
4. Open — Pack opening runs in real time; reward is drawn from the configured distribution.
5. Manage — User views inventory and transaction history; admins oversee operations via the dashboard.

• Next.js App Router with responsive UI optimized for the pack-opening experience
• Real-time updates via Socket.io during purchases, battles, and reveal flows
• User-facing account, wallet, cart, battles, upgrader, rewards, and history views
• Zustand for client state; HeroUI + Tailwind CSS for components and styling

• RESTful APIs and WebSocket events for auth, payments, packs, and rewards
• Idempotent payment webhook handling for NOWPayments callbacks
• Server-side reward resolution—outcomes are determined on the backend, not the client
• Structured logging and transaction records for auditability

• Crypto deposit flow with IPN/webhook confirmation
• Balance crediting only after verified payment status
• Reconciliation support for admin and support workflows

• User lookup and account management
• Pack and reward catalog configuration
• Probability / loot-table management
• Transaction and payment monitoring
• Platform settings and operational controls

• Performance — Low-latency openings and responsive UI under load
• Scalability — Stateless services and data layers that scale horizontally
• Security — Server-authoritative rewards, validated webhooks, and protected admin routes
• User experience — Clear flows from deposit → purchase → reveal → inventory
• Operational flexibility — Admin tools to adjust catalog and monitor health without redeploys

• Node.js 18+ and npm
• A running PackDraw backend API (from the full platform) for authenticated and live features
• Optional: Pinata credentials for avatar/image uploads; Google Cloud OAuth client ID for Google sign-in

git clone https://github.com/<your-username>/packdraw.git
cd packdraw

npm install

Copy the example file and set your values:

cp env.example .env.local

On Windows, if .env.local is blocked, use env.local instead (as noted in env.example).

Example .env.local:

NEXT_PUBLIC_API_URL=http://localhost:3000/api/v1
NEXT_PUBLIC_GOOGLE_CLIENT_ID=your_google_client_id
NEXT_PUBLIC_PINATA_API_KEY=
NEXT_PUBLIC_PINATA_API_SECRET=
NEXT_PUBLIC_PINATA_GATEWAY_URL=https://gateway.pinata.cloud/ipfs

# Development (default: http://localhost:80)
npm run dev

# Production build
npm run build
npm start

Notes:

• The dev script binds to port 80. On some systems that requires elevated permissions; if startup fails, run on another port, e.g. npx next dev --webpack --port 3000.
• Point NEXT_PUBLIC_API_URL at your backend. Without it, the UI renders but API calls and WebSockets will fail.
• Google sign-in needs a valid NEXT_PUBLIC_GOOGLE_CLIENT_ID and the redirect URI configured in Google Cloud Console.

• Server-side RNG — Reward outcomes must never be computed or trusted on the client.
• Webhook verification — Validate NOWPayments IPN signatures and payment status before balance updates.
• Idempotency — Handle duplicate webhook deliveries without double-crediting accounts.
• Admin access — Role-based access control; admin routes protected and audited.
• Rate limiting — Apply limits on auth, payment, and pack-opening endpoints.
• Secrets — Never commit API keys; use environment variables and secret managers in production.
