This addon allows you to exchange a large variety of minecraft items into coins, and you can use the coins to generate new items. It's inspired by other addons similar to it like Project E.
2 Blocks are added in this addon, the Create Table, and the Salvage Table. The salvage table lets you turn items into coins. The create table lets you turn coins into items. If you have any other questions you can craft the Item Exchange Tutorial Book or you can ask on the discord. The 3 items can be crafted in the crafting table using the recipe book.
The new balanced version makes your items salvage for 1/4 the value, designed for more difficult modpacks.
