I sent tokens to the contract address/ incorrect address as a mistake, can I receive it back?
No. That's a smart contract, and he team cannot touch what's in there, there's no way of getting those tokens back. The team will never be able to withdraw it, nor will anybody else. Unfortunately, that's the way smart contracts work, there's nothing we can do. Those tokens are forever lost to the world because it is not a proper wallet (that receives assets), but a contract.
