Can a public function be called from another contract? When add an interface for Contract A within Contract B, it says function calls from made within B from the Contract A Interface must be declared external

public is both external and internal

Yeah! I thought so, that's why I'm confused to why Remix wont let me interface a public function from contract A to contract B

modifiers are always internal, and modifers can't be in interfaces anyway

I'm having difficulties finding proper documentation on where modifiers can be declared, but I don't think you can declare them (well, their signature) in interfaces.

how is that related to modifiers? or are we mixing up the two uses of the term: visibility modifier (external, internal, ...) and the modifier keyword? I guess we are :)

great, settled ;)

anyway to answer you question, just put the visibility modifier as external when declaring interface for contract A inside contract B

This is what I mean

So even if the function inside contract A is public I declare it as external when I cull it in the interface

yep

Thank you! I thought they had to match. Learned something today

well don't listen to events. listen to new transactions. and it would be better suited for you if you're tracking one ( or a couple) pairs, that you listen to those pairs only

Filter out the noise
