Stakeable.calculateStakeReward(Stakeable.Stake) (#353-355) performs a multiplication on the result of a division:
-(((block.timestamp - _current_stake.since) / 60) * _current_stake.amount) * rewardPerMin / 16000000000 (#354)
Consider ordering multiplication before division.

External calls:
- _pair = IFactory(_router.factory()).createPair(address(this),_router.WETH()) (#836-837)

ERC20.stake(uint256) (#412-417) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(_amount < _balances[msg.sender],DevToken: Cannot stake more than you own) (#413)
Avoid relying on block.timestamp.
