Stupidly fried my Uno - anything else?

Me, being an idiot, decided to solder a joint while the Uno was still plugged in. Instant smoke. So the Uno is fried, that's for sure. Does the board have some sort of safeguard so that if it fries, everything else is fine? Or should I anticipate having to rebuild everything from scratch?

Depends on what was connected and how…

I figured as much. It's complicated. I'll probably just have to wait until my new Uno arrives.
