FAQ: Trading & Barter Systems
How do you prevent item duplication exploits?
We use server-authoritative transaction validation, atomic database operations, and anti-cheat hooks to prevent all known duping methods.
Can you build a real-money trading system?
Yes, with compliance considerations. We build RMT-ready systems with KYC hooks, tax reporting APIs, and fraud detection for games targeting adult markets.
How do you prevent hyperinflation?
Through currency sinks (repair costs, auction fees, cosmetic purchases), supply caps on valuable items, and real-time economy monitoring dashboards.
What data do economy systems generate?
Full transaction logs, price history, velocity metrics, and player wealth distribution — all exportable to your analytics platform.
Can trading systems work in mobile games?
Yes. We build asynchronous mobile-friendly trading systems with push notification alerts for trade offers and auction results.
