FLAG [Flag Network] Token

Contract creator or owner is blacklisted for past scams

Contract ownership is not renounced (belongs to a wallet)

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

Token.rebase_percentage(uint256,bool) (#315-321) performs a multiplication on the result of a division:
-newSupply = rebase(0,int256(_totalSupply.div(1000).mul(_percentage_base1000))) (#319)
Token.rebase_percentage(uint256,bool) (#315-321) performs a multiplication on the result of a division:
-newSupply = rebase(0,int256(_totalSupply.div(1000).mul(_percentage_base1000)).mul(- 1)) (#317)
Consider ordering multiplication before division.

Reentrancy in Token.rebase(uint256,int256) (#323-346):
External calls:
- pairContract.sync() (#342)
Event emitted after the call(s):
- LogRebase(epoch,_totalSupply) (#344)
Apply the check-effects-interactions pattern.

Token._rLockBalanceOf(address).total (#272) 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.

- master = _master (#420)
Emit an event for critical parameter changes.

Pragma version^0.8.2 (#6) allows old versions
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.

Token._rLockBalanceOf(address) (#271-281) uses timestamp for comparisons
Dangerous comparisons:
- block.timestamp <= _timestamp (#276)
Token.changeUnlockTimestamp(address,uint256) (#265-270) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp < lockTimestamps[_contractAddress],Can not change now) (#267)
- require(bool,string)(_timestamp > block.timestamp,Invalid timestamp) (#268)

Dangerous comparisons:
- require(bool,string)(_timestamp > block.timestamp,Invalid timestamp) (#261)
Avoid relying on block.timestamp.
