1.) I asked a Kraken support on reddit about the $STAKE listing, he replied to me this: https://support.kraken.com/hc/en-us/articles/360001388206-New-coin-listing-requests (" * If you are interested in any particular coin to be listed on Kraken, feel free to share this link with the respective developers.") so I am here. Dear Developers!
2.) There is a " Request For Comments and Code (RFC&C) Event" for BAT: Brave/BAT Ads and THEMIS I tagged Igor on reddit but didnt get answer yet!
I dont know if this is the official way to reach the xdai team, but worth a try, since I dont want to reg to twitter and couldnt find any other platforms.
Thanks in advance!
