Products

Premium systems — built and tested for real servers.

Built like an exchange

Not flavour text — a real matching engine where scarcity, surplus and speculation become real numbers on a real bid/ask spread.

Order book

Limit buy/sell orders, price-time matching, partial fills and price improvement.

Multi-market

Global, isolated and hybrid economies. Regional price gaps, black markets, arbitrage.

Warehouse & wallet

Personal item warehouse and a market wallet with configurable fees.

Safe by design

Server-side validation, atomic race-safe balances, parameterized SQL, webhook logs.

Bring a living economy to your server

Players set the prices. You get a genuine money sink, a trader playstyle, and emergent markets — not another fixed-price shop.
