_mint(msg.sender, ? *? ** decimals());

It should look like this

_mint(msg.sender, 500000000000000 * 10 ** decimals());

You should test the contract first inside a testnet network before deploying in production.

For your second question about the price, i dont have an easy answer for this because the price wont be in USD, it will be generated based on the ratio of the tokens’ quantities in the pool.

A few articles that you should check before starting developing your contract

Hi, im not familiar myself with token creation and the best implementation.

I recommend doing some research on the best practices there

HI thanks do you know how can i add fee in contract?

Hi @omid007m

You will have to define your own logic to add fees to the contract. For example, if you want to add fees for minting NFT, you will define a payable function with the code to transfer fees followed by the minting function.
