Exchange is a mod that gives us a very simple way to exchange items with other players, ensuring transactions between the two, and preventing one of the players from not fulfilling their end of the bargain when exchanging certain objects against others. Something quite common, especially on public Minecraft servers.
With this mod installed, when a player wants to trade with another, they just have to press the “V” key while aiming at the player. The other player must do the same. At this time, an interface will open that will allow us to add the objects that we want to exchange with another player. Once the items have been added, the “Ready” button is clicked, and when the other player clicks “Ready”, three seconds later, the two players’ items will be exchanged.
