Hi,

So I know that meltdown protects effects that happen on summon or quick effects of you declare them on summon but I'm not sure about IF effects

For example, Guardian Chimera's pop/ draw effect.

That's an IF he's fusion summoned.

So is it protected under meltdown or is it the start of a new chain?

He's protected as well.

Yes meltdown prevents your opponent from using effects in the summon response chain.
