Crate framework is being eliminated for another one from xingwang's blog

Crate framework is being eliminated for another one: Blueprints. Engineer Psyonix declared today that the change is Rocket League Items coming in December. 

Psyonix reported in August it was eliminating Crates from Rocket League, following Epic Games' lead with its expulsion of plunder boxes from Fortnite's Save the World. In Rocket League, players will get the opportunity to get Blueprints in the wake of playing matches. These things will show what can be made, and afterward player will pick on the off chance that they need to make it. Players should pay to make the thing utilizing Credits as opposed to buying a key to open a Crate. Credits are the "new superior cash" coming to Rocket League with the December update. They can be utilized to make Blueprint things, purchase stuff from the new Item Shop, and move up to Rocket Pass Premium. 

"Like the Crate things that www.lolga.com went before them, Blueprints can drop with extraordinary properties like Painted, Certified, and Special Editions," Psyonix wrote in a blog entry delineating the framework.
