Contract ticker ($SANTAL) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

SantaLottery.addLiquidity(uint256,uint256) (#674-684) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#676-683)
Ensure that all the return values of the function calls are used.
