World Marketplace
by Sleppi
World Marketplace is a NeoForge economy mod for 1.21.8 that adds item-based vault currencies, a global marketplace and a multi-account bank system.
What it does
Players set up vaults whose value is tied to a resource, such as a gold block or a diamond block, and use them as currency. Everybody can list items for sale or place trade offers on the marketplace, and purchases can be made with different vaults. Trade offers can also be used to pay for a service instead of an item.
The mod includes inflation and deflation mechanics that shift prices over time. Later updates changed some regulations and improved the formulas behind these mechanics. A bank system sits alongside the marketplace, letting players open several accounts in different currencies, deposit and withdraw money, and send money to another account.
The mod is published for NeoForge only, for 1.21.8. It runs on the client and on the server, so both sides need it. The code is not open source; the author Sleppi keeps all rights reserved. Its files are in the beta channel, with 0.1.5 as the latest, published on 2025-11-27.

Inflation and deflation
Prices move through inflation and deflation mechanics, with formulas adjusted by later regulation updates.
Multi-currency bank
