Hi everybody, wondering what my best option is for getting the ABI of a compiled smart contract (source unpublished). Are there any tools that can rebuild it from a decompiled version of the contract perhaps? Or am I best recreating it based on known interactions with the contract?

I think there is a decompiler on etherescan and the decompiled code would take some extra work to (manually) extract ABIs, but I'm not sure.

Yep I think that might be the process here. Cheers

A quick question: if a contract factory has generated quite a bunch of contracts by cloning, and one parameter is desired to be updated across all such contracts, what is the best approach for achieving that? Suppose a setter is available for all such contracts. And a good measure would be low gas costs, and easy to implement and quick in execution.

In my opinion, the best solution would be if you store this value in the factory contract, and request it from the clone contract when necessary.

Yes, this is a good approach. I forgot to mention one more constraint, which is the generated contracts do not belong to me, or any known individual. They are in the wild.

I do not understand. What prevents the clone contract constructor from accepting the factory address to which the contact will contact?

I think we cannot assume that contract owners would update contracts by contacting the factory, and in the worst, they perhaps do not even know about it.
