Okay Bro I try it once more to explain. I am nopt deploying a contract or any sort of that stuff. I am developing a webapp, user is connected with metamask, there is an Inputfield where he can input the contract he says he owns, HOW can I verify that he owns the contract, the contract is not mine, I only have the address of the contract he says he owns and his accounts he obv has the private keys to, since he has them in his metamask. Is there a way via signature or whatsoever mechanic to verify he owns the contract, he is the DEPLOYER of the contract
