When you talked about Metamask, I chuckled, yeah, it is a bit tough to configure a thing like that even for me. Bypassing Metamask is a good idea.
I've not used Leo Finance yet, I'm just on the Hive Blog app, but I think Leo is like a side chain of Hive or that aspects of it might be apart from a post like this. Is CUB Finance an app of Leo Finance, is it somewhat connected or related?
