Exchange
This mod adds a mechanism to inject currency into a server economy, as an alternative to the universal-basic-income feature of the currency mod. It is an interesting idea of jonadab.
I recommend to deactivate income mechanism (in currency) and interest mechanism (in atm, if loaded).
The mod adds a ``Trade counter'' node that allows to obtain minegeld from "rare" metals.
Glooptest mod dependency was made optional by including part of its code.
