The Blueprint Update introduced a system called Blueprints.

After you play a match, you’ll have a chance to obtain a Blueprint. This is a type of drop that replaced Crates. Blueprints show an item that can be built, and the price in Credits to build it. Once in your inventory, you may choose to pay the Credits to build the item or keep the Blueprint to build or trade later. Like items from Crates, the items from Blueprints may have special attributes like Painted and Certified.

Credits are a type of currency that replaced Keys. Credits can be used to build items from Blueprints, purchase items from the Item Shop or upgrade to Rocket Pass Premium. Keys were converted into Credits on December 4, 2019 when the Blueprint Update went live. Any Keys in your inventory were converted on your first log-in after the update. Additionally, crates were converted to Unrevealed Blueprints after the Blueprint update, which can be revealed at no cost.

After an Online Match, there is a chance that you will get a revealed Blueprint. You can then build the item with Credits, trade the Blueprint to another player, or keep it in your inventory for later. A confirmation message will be presented to you before completing your purchase. This message will display the platform username, the Blueprint, and the cost to build the Blueprint.

If you are a child and your parent hasn't helped you set up your account, you may have a Cabined Account with different features. If you think you might have a Cabined Account, visit: Why does my Rocket League account say that some features are disabled?

Once parental controls are set up for your account, you may be granted access to additional in-game features allowed by your parent or guardian.
