I'm implementing a smart-contract in Plutus and I'm with a doubt. For example, Ethereum has some function only to owners, that enables to implement a withdraw of balance for only owner addresses.
I know, that in the script validator, I can put a clause that is true only with a specific public key hash. And I already implemented that. And it works... but only if I locked ADA or NFT through the smart contract itself. Imagine that I sent an NFT or ADA with the nami directly to the address... this way, I receive "'Inputs do not conform to this spec or are otherwise invalid.'". It is normal? There is a way to solve this? Or it is possible at least?
