Hi, when I send an internal message to contract A -(msg 1)-> contract B -(msg 2)-> contract C -(msg 3)-> contract D, if msg 3 being processed in contract D throws an exception, all are the msg processing (msg 1, msg2, msg3) reverted or only msg 3 reverted and msg 1,2 executed?

Only processing of msg 3 will be failed, 1,2 excuted.

Developer have to handle all this cases in contracts logic. So, when something going wrong, for example, Contract D should send "notification" message, say, to contract A. But it means, we need to know, what could be wrong, of course.

Acquire everything by your contracts (which probably would not fail) then do all outgoing actions.

That's where formal description and verification is needed) I've recently posted such a footstep so I think someone could take it.

then, with dex aggregator case, does all dex provide revert message receiver ( for slippage case ) ?
