First EVP Claim

The EVP event was yet another event in Splinterlands that I was not too intuned with; even now. However, my Collectionist tick made me participate with a purchase of the Legendary card. I was surprised to see how that sold out and sort of regretted not getting a maxed copy but that is behind me at the moment. Since land is my focus at the moment, I immediately put it somewhere on my land.
After a couple of weeks, I went in and claimed my first stack of EVP. It was uneventful but I am so confused as there is really nothing I can do with it at the moment. Not sure why I cannot claim any of the chests at the moment. It seems it is related to my wallet not being connected and it is likely because I use separate accounts for my land assets. I will have to figure it out in the future to use some of this EVP. Any recommendations?
I didn't know about this use case. Is EVP part of future economy in Splinterlands?
