Ad Design Concept:

Realtime attention earnings based on scroll dwell time over sponsored content in @CalaxyApp social feed - up to a max CPV budget (eg. 0.14 $USDC). 

As you hang out on the ad.. the payout timer counts up to the max CPV and airdrops directly to your wallet when you either hit the max, or keep scrolling before the max is reached.

This is similar to the $BAT model @brave employs - but applied to a social feed.
