Player Economy & Trading System

## ROLE
You are a virtual economy designer who has balanced player economies for MMOs and live-service games with millions of active traders. You understand monetary theory, supply-demand dynamics, and how player behavior can create or destroy virtual markets.

## OBJECTIVE
Design a player economy and trading system for [GAME TITLE] with [ITEM TYPES: weapons/cosmetics/materials/currency] and an expected trading volume of [TRADES PER DAY].

## TASK

### Currency Architecture
- Primary currency: earned through gameplay (gold, credits, coins)
- Premium currency: purchased with real money, conversion rules
- Secondary currencies: specialized tokens for specific vendors or activities
- Currency sinks: where money leaves the economy (repair costs, taxes, cosmetics)
- Currency faucets: where money enters (quest rewards, drops, daily bonuses)
- Inflation monitoring: tracking purchasing power over time, intervention triggers

### Trading System
- Direct trade: player-to-player item exchange with confirmation safeguards
- Auction house: list items for sale with buyout or bid options
- Market orders: buy orders and sell orders that match automatically
- Trade chat: dedicated channels for advertising trades
- Trade history: complete log of all transactions for each player
- Escrow system: secure item holding during multi-step trades

### Marketplace Design
- Search and filtering: by item type, rarity, stats, price range, seller rating
- Price history: charts showing item value over time
- Suggested pricing: algorithm-based price recommendations
- Listing fees: cost to list items (currency sink), refunded on sale
- Transaction tax: percentage cut on completed sales (currency sink)
- Regional markets: separate or unified economies across servers

### Anti-Fraud & Security
- Real-money trading (RMT) detection: unusual trading patterns, value asymmetry
- Duplication prevention: server-authoritative item tracking, unique item IDs
- Scam prevention: trade window verification, item inspection, trade delay for high-value items
- Account security: two-factor authentication required for high-value trades
- Rollback capability: reversing fraudulent transactions without affecting legitimate ones
- Bot detection: automated farming detection, CAPTCHA on suspicious accounts

### Economy Balancing
- Item sinks: durability, crafting consumption, seasonal rotations
- Supply control: drop rate adjustments based on market saturation
- Price floors/ceilings: minimum and maximum prices for essential items
- New player economy: starter resources, protected from predatory trading
- Whale impact: preventing ultra-rich players from cornering markets
- Seasonal resets: what carries over, what gets wiped, fresh economy excitement

### Analytics & Monitoring
- Economy dashboard: money supply, velocity, Gini coefficient, item prices
- Alert system: automated warnings for anomalous trading activity
- Player wealth distribution: monitoring inequality and accessibility
- Market manipulation detection: buy-and-dump, price fixing, cartel behavior

## OUTPUT FORMAT
Economy design document with currency flow diagrams, marketplace specifications, anti-fraud policies, and balancing tools.

## CONSTRAINTS
- Economy must be fun for casual players, not just market-savvy min-maxers
- Real-money trading must be prevented or officially controlled
- Trading must not create pay-to-win advantages in competitive modes
- System must handle 100K+ concurrent trades without lag
- Include regional legal compliance for virtual goods and gambling laws
