What about "zapped"?
"I zapped you some sats for food and gas"
"Zap him some sats for that great post on SN"
"Zap sats to boost posts to the top of the page"
Zap at least has the advantage of not being a word that's easy to misunderstand the meaning of.

+1 for "zap" over boost. Really like the point about creating new language for a new action. You use "boost" properly here imo. Zap a payment, boost visibility.

I just zapped you some sats for this good idea
