Welcome to Cash City

The Trading Floor is open. Build your empire.

Cash City is a Solana-based Trading Firm simulator where you run your own Firms, hire Interns, and compete for a share of daily $CASH emissions. Every decision — which Interns to seat, when to upgrade, how aggressively to hire — affects your cut of the pie.

This documentation covers everything you need to know: how the game works, the math behind the economy, and how to make the most of your time on the trading floor.

Cash City is invite-only. You need an access code to play. Every player in the game can generate invite codes — find one on X (Twitter) or ask someone already inside.
