This seems like a very capable and solidly built project. Well done!

That being said, I can't wrap my head around the naming. Why tips.io? What do tips mean in this context?

(PS: Excuse me if it's covered in the promo video, I'm currently in a zoom call and I can't put any audio through right now)

Super true. I know... I bought this domain a long time ago for another project that never launched and swore to use it one day. It's a short .io that is easy to remember. I agree it does not match well

First thought as well. Apart from “cool.tips”, it makes everything sound like you’re on a patreon page.
