Hey guys .. i use call to call a

function from a proxy contract (address(proxy).call(data)) .. as i undersatnd the signature of the function i called does not match any function in the proxy it self so it will invoke the fullback function. the fallback function has an implementation that delegatecall to another contract that have this function i called , however the delegatedcall got revert ;
the issue is the call function returned true ?i don't get it ? any one please can explain ?

Interesting. So the call returned false even though there was a fallback with an external call?

Low level call doesn't care about other internal calls. In this case, call executed "successfully" as there was a fallback. If the fallback wasn't there, you would've got a false. If you make a transaction like this, the explorer will show it as a successful tx with a small warning that says something like 'one or more internal transactions failed'
