Player marketplace, direct trading, and shops.
Market & Trading
ED5 includes a player-driven economy with marketplace listings, direct trading, NPC shops, and premium stores.
Player Marketplace
Players can list items for sale on a shared marketplace:
| Feature | Description |
|---|---|
| Listing | Set price, quantity, and expiration time |
| Tax | Configurable tax rate on sales |
| Expiration | Listings auto-expire after a set duration |
| Search | Browse by type, tier, quality, and price range |
| Price history | Per-item candlestick charts built from real trades |
| Purchase | Buy instantly at the listed price |
In game the market is a searchable trading terminal: filter the item list, open an item to see its order book and price history, and buy or list from the same panel.
Direct Trading
Two players can open a trade window to exchange items and gold: 1. Player A requests a trade with Player B 2. Both add items and/or gold to the trade window 3. Both confirm 4. The server validates everything and swaps items atomically
Currency Exchange
An order-book system for converting gold ↔ premium currency:
- Players place buy or sell orders
- Orders match automatically
- Exchange rates are determined by player supply and demand
NPC Shops
NPC merchants sell items at configured prices and buy player items at a reduced rate:
- Sell price — base price × shop markup
- Buy price — base price × buy multiplier (default: 0.4×, i.e. 40% of base price)
- Stock — configurable quantity with restock timers
- Reputation gating — some items require faction reputation
Premium Shop
An optional real-money store (ships on; turn it off in World → Features if your game has no monetization):
- Products — individual items or bundles
- Scheduling — time-limited availability windows
- Purchase limits — per-account caps
- Promotions — percentage discounts, fixed amount off, buy-X-get-Y
Premium Membership
The account-wide gold sink that closes the economy loop. Players spend account gold — earned in game, or bought through the Gold Store and traded on the exchange — on a timed membership plan you author (duration in days, price, and perks). While it's active the account gets config-driven perks such as bonus XP and bonus reward silver. Status is account-wide, persisted on the account wallet, and cached for cheap lookups whenever a reward is granted.
Because the gold comes out of circulation, membership is how you keep gold scarce without deleting it by hand.
Gold Store
Configure real-money → gold conversion tiers with bulk bonuses. Integrates with Stripe/PayPal, with refund clawback and daily purchase caps.
Bank
Personal storage system separate from inventory — accessible at bank NPCs with expandable capacity.
