TTIToken.withdrawToken(address) (#1192-1194) ignores return value by IERC20(token).transfer(msg.sender,IERC20(token).balanceOf(address(this))) (#1193)
TTIToken.depositReward(uint256) (#1237-1242) ignores return value by IERC20(rewardToken).transferFrom(msg.sender,address(this),amount) (#1238)
TTIToken._claim(address,address) (#1244-1248) ignores return value by IERC20(_rewardToken).transfer(user,rewardTokenForAddresses[_rewardToken][user]) (#1246)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

TTIToken.slitherConstructorVariables() (#1113-1337) uses literals with too many digits:
- maxSupply = 160000000 * (10 ** 18) (#1135)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

TTIToken.factoryAddress (#1118) should be constant
TTIToken.maxSupply (#1135) should be constant
