    We have an Ethereum Smart Contract and a Learn To Earn program. We want to ensure that when users convert their earned points into our tokens, they pay the Transaction cost. However, since the functions are public, we are concerned that users can mint additional tokens on our contract. Thus, we want an expert dev to review our contract and recommend the ideal way to set these functions up. Additionally, we are using 1Inch for processing transactions and want the users to be charged a transaction fee. However, since 1inch doesn't support it, the only option is for the users to pay double transaction fee - one for their transaction and the other to pay us a fee. We would like the expert developer to help us find a solution to this as well, if possible.
