Coinbound

Coinbound

Coinbound adds a complete survival economy with balanced prices for every registered item. Buy resources from a searchable shop, sell items directly from your hand, collect valuable enchanted equipment, and trade functional mob spawners.

Features

• Balanced buying and selling prices for all standard items
• Automatic pricing for compatible items from other mods
• Prices calculated from rarity, materials, recipes, and crafted output
• Searchable shop with categories and price sorting
• Sort from cheapest to most expensive or the other way around
• Persistent player balance displayed on the HUD
• Enchanted equipment has a higher value based on its enchantments
• Item durability affects its selling price
• Filled containers cannot be sold accidentally

Special Offers

The shop contains 114 special offers, including:

• Three complete enchanted armor sets: Explorer, Guardian, and Legend
• Individual enchanted armor pieces
• Powerful swords, pickaxes, a bow, a trident, a mace, and enchanted elytra
• 77 enchanted books with different enchantments and levels
• Legendary equipment with selected enchantments above normal levels

Complete armor sets are purchased as four separate items in one transaction. If the inventory does not have enough space, the purchase is cancelled without charging the player.
