Minting fees added

Hello, again… Who can help me put a mining fee on an Nft contract? Please

how does the mint work now?

Normal, no fee only what the network charges… Or better yet how do I make the contract only I can make new tokens?

That is easier, you can check if msg.sender is your admin address, and if not then the execution will revert there

Ok now I make an example and you tell me if it is okay… Please…
