Godot Economy System

This handles the full stack of game economy patterns: multi-currency wallets, shop systems with buy/sell spreads, dynamic pricing based on demand, weighted loot tables, and currency sinks to prevent inflation. It includes ten ready-to-use scripts covering everything from secure transaction processing through the WalletManager singleton to UI sync components and persistence handlers. The "NEVER" section is genuinely useful, calling out common pitfalls like client-side validation in multiplayer, integer overflow for premium currencies, and floating point precision errors. Best for RPGs or trading games where you need the economic simulation to feel balanced and exploit-proof without reinventing the wheel.
