x99Token is a crypto token build on the Binance Smart Chain. Use x99Token to play in x99Game or stake in the liquidity pool & earn tokens! Crypto moonshot.
LiquidityGeneratorToken.addLiquidity(uint256,uint256) (contracts/tokens/LiquidityGeneratorToken.sol#587-600) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (contracts/tokens/LiquidityGeneratorToken.sol#592-599)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
