EVOCARDANO.addLiquidity(uint256,uint256) (Evocardano.sol#443-458) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (Evocardano.sol#449-456)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

EVOCARDANO.totalFees (Evocardano.sol#46) is set pre-construction with a non-constant function or state variable:
- ADARewardsFee.add(liquidityFee).add(marketingFee)
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

EVOCARDANODividendTracker.getAccount(address) (Evocardano.sol#532-575) uses timestamp for comparisons
Dangerous comparisons:
- nextClaimTime > block.timestamp (Evocardano.sol#572-574)
EVOCARDANODividendTracker.canAutoClaim(uint256) (Evocardano.sol#596-602) uses timestamp for comparisons
Dangerous comparisons:
