The Uniswap invariant x*y=k was not satisfied by the swap. This usually means one of the tokens you are swapping incorporates custom behavior on transfer

when i try to swap…i am getting this error on uniswap…my token has fees on transfer functionality.

Hi, so is there a failed transaction, you can share it at here, and then I can have a look.

also include the code for your cutsom transfer function please
