Craftanomics
by JackATack
Craftanomics gives a server an economy with dynamic item prices, a player market and a set of supplementary systems, and runs on Fabric for 1.21.10.
What it does
Craftanomics implements a server economy in which items receive dynamic prices, and players buy and sell through a server market. Every player has a cash balance, kept by the Aura system in Minecraft's PlayerData, and administrators can change balances from commands. Most of the economy data can be edited in a data.json file, and item prices in an items.json file or through the econ admin editItems command.
The mod is built around a core economy with several complementary systems, such as Death Betting, where players wager on upcoming player deaths as a lighthearted feature. Those systems are enabled by default and can be disabled in the Craftanomics config file, which also holds further settings and event scheduling. Smaller servers get a reason to keep players active: the mod gives people a shared incentive to play at the same time, cooperate and automate farms, which helps keep a server from fading out. Craftanomics requires Fabric API and runs on the server only, so players join without installing anything.
Key features
Dynamic market pricing
Items follow a basic dynamic price model based on an anchor price, a supply factor and demand, which set the actual purchase price.
Three market models
Items use the Normal, Linked or Static model. Static items keep a fixed buy and sell price, which suits a currency item.
Linked items
A linked item takes its price from another item, so Gold Blocks always cost nine times a Gold Ingot and selling one affects supply like nine ingots would.
Death Betting
Players wager on the deaths of other players, a light entertainment system that can be turned off in the config.
Editable economy data
Nearly all economy values can be changed in data.json, and item prices in items.json or with the econ admin editItems command.

How it compares
Back's Economy is a Fabric economy mod for 1.21.1 under All rights reserved, not open source. Snurbo's Shops is also a Fabric mod for 1.21.1 and is not open source, but a server requires it while clients may leave it out. OPKONTOR is a Fabric mod for 1.21.11 that is not open source and is client-side only, so it differs from Craftanomics, which is server-side only.
