First of all i really liked how the oveall system works, its pretty cool but there are somebugs when i started testing first time i face no swap, stake etc issues but after some time when i again try it everything i try gave me tx error and none of the tx would go through also there is sometime website doesnt pickup my wallet balance and i have to refresh several time in order to it work, Also there are some broken pages but i guess it still in beta, Thats All, I hope the devs would fix these issues
