ChestTrade allows you to trade items with other players using chests. This allows remote trades (even inter-world trades) and prevents griefing, since players will know exactly what their counterpart will give in return for their items. Also, no 3rd party players are able to interfere with the trades.
ChestTrade will use single chests as items holders for the trade. During the trade process, the chests are only accessible to editing by their owner, and the counterpart (henceforward called "partner") is able to see one's chest contents. When the trade is finished, the chests' inventories are swapped and the players can get theirs partners' items in the chest they used.
The trading process is explained in detail in this page.
