I'm working on an Erlang/Elixir SDK for Stellar and just wanted to spread the word and seek help from anyone that's interested. I started about a month and a half ago (on and off) and am still working through XDR encoding. I have WIP pull request (which I'm working on cleaning up before merge), where anybody can see the XDR work being done.
Why another SDK?
I like the Erlang VM and think it's a perfect fit for interacting with the Stellar network. If you are not familiar with the features of the EVM, I highly suggest you look them up. I am also working on this SDK so I can use it myself for future projects.
Anyway, I will gladly accept any help from people that are interested. I am on the Stellar slack under the same username if you want to PM me.
