Also they show it working on twitter but I don't see any documentation about using Iframes. Also does not seem to be open source...
I'm sure it takes a centralized server and it would be a great opportunity to have multiple "blinks" servers 😞

Yeah, the promo video is very odd. It clearly looks like twitter, but if you look closely, the url is sola.na/actions which points to a totally different page. Also there is no way in hell Elon will allow them to have iframes like that.
Ok, so it turns out you need a browser extension to view the nice UI instead of just a link. https://x.com/solana/status/1805942449187250596
