BRN [Braination] Token

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Contract ownership is not renounced (belongs to a wallet)

Stakeable._stake(uint256,uint256,uint8,uint256,uint256,address) (#265-297) performs a multiplication on the result of a division:
-milliPercentOfUser = ((collectedReward - usedReward) * stakePart[stakeType]) * 100000 / (ccSupply * stakeAssumption[stakeType] * _stakeCoefficient) (#289)
-mustClaim = _amount * milliPercentOfUser / 100000 (#290)
Consider ordering multiplication before division.

Braination.withdrawAll().totalStakeAmount (#916) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Braination.allowance(address,address).owner (#526) shadows:
- Ownable.owner() (#107-109) (function)
Braination._approve(address,address,uint256).owner (#551) shadows:
- Ownable.owner() (#107-109) (function)
Rename the local variables that shadow another component.

Braination.totalFrozenAmount() (#629-639) uses timestamp for comparisons
Dangerous comparisons:
- quarter < 3 (#632)
Braination.stake(uint256,address,uint8) (#874-900) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp - lastStakeTime[msg.sender] > 600,you can stake once in every 10 minutes) (#878)
- require(bool,string)(_amount < _balances[msg.sender] - frozen,can't stake frozen amount) (#883)
- require(bool,string)(_amount < maximumStakableAmount,can't stake more than 2% of stakeable amount) (#890)
Braination._transfer(address,address,uint256) (#654-682) uses timestamp for comparisons
Dangerous comparisons:
- require(bool)(checkIfBalanceNotFrozen(sender,amount,block.timestamp)) (#659)
Braination.addressFrozenAmount(address) (#612-621) uses timestamp for comparisons
Dangerous comparisons:
- quarter < 3 (#615)
Braination.checkIfBalanceNotFrozen(address,uint256,uint256) (#593-602) uses timestamp for comparisons
Dangerous comparisons:
- quarter < 3 (#596)
- (balanceOf(sender) - frozen >= amount) (#598)
Stakeable.calculateClaimableReward(Stakeable.Stake) (#349-359) uses timestamp for comparisons
Dangerous comparisons:
- _current_stake.stakeType == 1 && daysPassed < _firstStakeTypeDuration (#353)
- _current_stake.stakeType == 2 && daysPassed < _secondtStakeTypeDuration (#354)
- _current_stake.stakeType == 3 && daysPassed < _thirdStakeTypeDuration (#355)
Avoid relying on block.timestamp.

Braination.excludeIncludeFeeFrom(address,bool) (#814-825) compares to a boolean constant:
-_noFeeFrom[account] && value == false (#819)
Braination.excludeIncludeFeeTo(address,bool) (#836-847) compares to a boolean constant:
-_noFeeTo[account] && value == false (#841)
Remove the equality to the boolean constant.

Braination.withdrawAll() (#913-947) has costly operations inside a loop:
- _totalStakedAmount -= withdrawable.stakes[i].amount (#929)
Braination.withdrawAll() (#913-947) has costly operations inside a loop:
- _applicableContractRewardAmount -= stakeReward (#930)
Use a local variable to hold the loop computation result.

solc-0.8.11 is not recommended for deployment
Pragma version^0.8.11 (#1) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
