Competitive Gaming Platform with Solana Payments — Full Tech Stack Breakdown

What We Built

LootDiff — a platform where gamers play CS2, Dota 2, and Deadlock for real USDC stakes. Here's the full stack.

Frontend

  • Next.js 14 with App Router
  • Tailwind CSS for styling
  • Solana Wallet Adapter for wallet connections

Backend

  • Supabase — PostgreSQL database + auth + real-time subscriptions
  • Vercel — Hosting + serverless functions + cron jobs
  • Redis — Match queue, rate limiting, caching

Blockchain

  • Solana — USDC escrow smart contracts
  • @solana/web3.js — Transaction building
  • Token Program — USDC SPL token handling

Game Integration

  • Steam Web API — CS2/Dota 2 match verification + VAC ban checking
  • Custom VAC checker — Runs every 6 hours, flags banned accounts

Automation (32 cron jobs)

  • Match notifications, tournament creation, city leaderboards
  • Social media posting (Twitter, Telegram, Discord, VK, Reddit)
  • Blog generation, meme posting, streamer discovery
  • Self-healing monitor + auto-retrigger

Key Challenges

  1. Escrow timing — Match results can take minutes to appear on Steam API. We poll with exponential backoff.
  2. Anti-cheat — VAC bans are binary but don't cover all cheats. We added ELO anomaly detection.
  3. Regional targeting — Turkey, CIS, Caucasus markets. Multilingual everything (EN/TR/RU).
