Contracts provide a way to use several skins from the KeyDrop inventory in one exchange. After items are selected, the interface shows an estimated reward value before the contract is created.
The catalog can be filtered by search, weapon type, sorting and price range. Contracts are useful when the goal is to clear duplicate or unwanted skins rather than select a specific target item. For direct target selection, compare the Skin Changer; for chance-based target upgrades, see the Upgrader.
