Both tokens will be on bsc the first will be USDT and the second will be my projects token.
12 months ago I launched a token and after a moderate presale it failed when it went to market and is dead now. Seeing that the coin is dead I wish to unlock my liquidity which is still locked until a few days time with pinklock but I don't know how to access it. I will give all details before hiring so you can check and confirm the amount and will hire winner to help me retrieve the liquidity.
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.
