Relvobot – Channel Currency / Loyalty System made easy
Revlobot is one of the most easiest bots to use when you want to offer a channel currency / loyalty system for your stream. It's a standalone service that you connect with your twitch account, set it up and manage everything over at one place.
You can do giveaways, contests, gambling, special commands only redeemable with points etc. There even is a leaderboard where you and your viewers can see who has been the most loyal viewer of all time.
