UNITY Game Integration with (BSC) blockchain.

I want to integrate game to (bsc) and later to Cardano and Solana blockchains. game is already designed . It is an action and strategy games on Unity platform , you have to make game assets as NFT with ability to purchase them before or doing the game and list them on sale (Next Project). reward users with tokens doing the game or at the end if they win. let me know if you can do it and how much it will cost. do not ask a budget otherwise will not respond.
