Roblox Dual Currency System: Soft Currency and Robux
Generate a professional dual-economy system for Roblox: a soft currency earned during gameplay and a premium currency purchased exclusively with Robux. The prompt guides the correct implementation of the Developer Products flow, avoiding the common mistake of trying to directly manipulate the player's Robux balance.
Ideal for games with stores, upgrades, cosmetics, boosts, gem packs, and persistent economies. The requested result includes server-authoritative architecture, DataStore, validated RemoteEvents, reward duplication prevention, and practical instructions to configure and test everything in Roblox Studio.
Act as a senior Roblox developer, specializing in Luau, game economies, DataStoreService, and secure monetization with MarketplaceService. Create a complete, secure, production-ready dual-currency system: one soft currency earned in-game and one premium currency purchased with Robux through Developer Products.
