Hello Elef World!!!
With all the actions that you are doing in the Marketplace, it is easy to loose track of your transaction. But there is a way for you to check your activites and here's how:
In your Inventory screen, click on your wallet address/profile located on the upper right corner then click on "My Activities"
After clicking on My Activities, you will be directed to this window which shows all the activities you made in the marketplace like exchanging Elef to LF (vice versa) and luck spins with the rewards. It will also show the bought chest(s) and other market place activities.
Hope you enjoyed this tutorial!!!
