Neuro/Evil is hosting The Grand Galactic Auction. Chat can bid by using channel points. All items up for auction are made up by neuro. The biding can be done through an external website that links to twitch to view your channel points/name for them to read out loud. I think this could be an interesting interactive stream, and could lead to having a stream with real items later on being auctioned.

sounds cool but im guessing instead of a separate site they could use the twitch extension plugin whatever thing that theyve already used for stuff like subnautica

yah that would be better, you would get more engagement and less risk of breaking.

That'd be pretty cool.
