Coinkeep

Players earn money by completing 180 quests across 10 chapters, covering Mining, Combat, Tools, Armor, Building and Farming, plus one chapter per vanilla advancement. Gathering quests repeat with escalating tiers, and two ladders track progress within each quest's tiers and across the whole chapter. Progress is tracked automatically, and lifetime totals are never reset.

Money is held as a banked balance that survives death, while cash in pockets does not. A money vault can only be opened and broken by its owner, and a thief cannot destroy someone's savings. Currency uses eighteen denominations, from 1 up to 100,000,000, and banknotes can be handed to another player. Shops are built from a categorised catalog, including rare finds such as Elytra, Totem and Nether Star, along with named pre-enchanted endgame gear. Prices respond to supply and demand.

Operators edit the catalog, prices and quests through ordinary JSON files in the world folder, or through a datapack, and changes apply to everyone after a reload or restart. Coinkeep needs the Client and server environment, so the server and every player need it. It is released under All rights reserved and is not open source. NeoForge files are published for 1.4.0+26.2 as the latest build, released 2026-10-10.
