FUNB [Funblock] Token

Token is flagged by TokenSniffer due to presence of exploit in contract code

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Contract ownership is not renounced (belongs to a wallet)

FunBlockToken.incRoundBalances(address,uint256) (contracts/FunBlockToken.sol#546-549) ignores return value by _roundBalances[account][_roundIndex].inc(amount) (contracts/FunBlockToken.sol#547)
Ensure that all the return values of the function calls are used.

Pragma version^0.8.2 (contracts/FunBlockToken.sol#2) allows old versions
solc-0.8.2 is not recommended for deployment
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.

FunBlockToken.slitherConstructorVariables() (contracts/FunBlockToken.sol#291-626) performs a multiplication on the result of a division:
-_tokenPerAirdrop = (_totalSupply.mul(300).div(10000)) * 10 ** _decimals (contracts/FunBlockToken.sol#301)
Consider ordering multiplication before division.

FunBlockToken.update(uint256,uint256) (contracts/FunBlockToken.sol#505-531) should emit an event for:
- _roundInSec = value (contracts/FunBlockToken.sol#507)
- _roundUnlockInSec = value (contracts/FunBlockToken.sol#510)
- _rate = value (contracts/FunBlockToken.sol#513)
- _saleRoundMin = value (contracts/FunBlockToken.sol#516)
Emit an event for critical parameter changes.

Reentrancy in FunBlockToken.buyToken() (contracts/FunBlockToken.sol#551-571):
External calls:
- (success) = address(uint160(_liquidity)).call{value: _msgValue}() (contracts/FunBlockToken.sol#560)
Event emitted after the call(s):
- Transfer(address(this),_msgSender(),_token) (contracts/FunBlockToken.sol#566)
Apply the check-effects-interactions pattern.

Rounds.getBalance(Rounds.RoundBalances,Rounds.RoundTime) (contracts/FunBlockToken.sol#243-268) uses timestamp for comparisons
Dangerous comparisons:
- round.status == 1 && block.timestamp > roundTime.unlockStart (contracts/FunBlockToken.sol#245)
- block.timestamp >= roundTime.unlockEnd (contracts/FunBlockToken.sol#251)
- sec > 0 && sec < end (contracts/FunBlockToken.sol#256)
- balance > round.claim (contracts/FunBlockToken.sol#258)
- sec > 0 && sec >= end && round.total > round.claim (contracts/FunBlockToken.sol#263)
Rounds.settle(Rounds.RoundBalances,Rounds.RoundTime,uint256) (contracts/FunBlockToken.sol#270-287) uses timestamp for comparisons
Dangerous comparisons:
- amount > balance (contracts/FunBlockToken.sol#274)
FunBlockToken.getRoundPrice() (contracts/FunBlockToken.sol#533-544) uses timestamp for comparisons
Dangerous comparisons:
- block.timestamp >= _roundTime[_roundIndex].end (contracts/FunBlockToken.sol#534)
Avoid relying on block.timestamp.

FunBlockToken._tokenPerAirdrop (contracts/FunBlockToken.sol#301) is set pre-construction with a non-constant function or state variable:
- (_totalSupply.mul(300).div(10000)) * 10 ** _decimals
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.

Low level call in FunBlockToken.buyToken() (contracts/FunBlockToken.sol#551-571):
- (success) = address(uint160(_liquidity)).call{value: _msgValue}() (contracts/FunBlockToken.sol#560)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
