RONINGMZ [Ronin Gamez] Token

Contract creator or owner is blacklisted for past scams

Ronin.addLiquidity(uint256,uint256) (Ronin.sol#320-336) sends eth to arbitrary user
Dangerous calls:
- (ethFromLiquidity) = uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (Ronin.sol#326-333)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
