Can You Sell Items in Rocket League? Photo : Unsplash Online trading markets for in-game items and currency have been the talk for a while now, but not all of them are recognized as the CS:GO trading hub. One of those that aren't as well known is the Rocket League trading marketplace. Unlike some other games, Rocket League isn't best known for the trading system but rather for the highly entertaining gameplay. However, the trading system is there, and it can be a very fun aspect of the game. Rocket League Has a Large Marketplace Believe it or not, there is a huge marketplace out there that deals with trading Rocket League items for both in-game currencies or even for straight-up cash. This has been implemented way back in 2016 but has received significant updates since the conception, like the Trade-In system and some additional security measures. One of the most significant changes has been the transition from a standard system that used chests and keys for loot to a much safer system that includes blueprints and credits.
