Champion Tiger Token

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

Contract locking ether found:
Contract ChampionTiger (#949-1129) has payable functions:
- ChampionTiger.receive() (#1127)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

Contract ticker (Champion Tiger) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

ChampionTiger._transfer(address,address,uint256) (#1069-1124) performs a multiplication on the result of a division:
-_fee = amount.mul(sellFeeRate).div(100) (#1104)
-super._transfer(sender,mintContract,_fee.mul(40).div(100)) (#1105)

ChampionTiger._transfer(address,address,uint256) (#1069-1124) performs a multiplication on the result of a division:
-_fee_scope_0 = amount.mul(buyFeeRate).div(100) (#1116)
-super._transfer(sender,addressForMarketing,_fee_scope_0.sub(_fee_scope_0.mul(60).div(100))) (#1118)
Consider ordering multiplication before division.

ChampionTiger.antiBot(uint256) (#1029-1036) should emit an event for:
- antiBotAmount = amount (#1033)
Emit an event for critical parameter changes.

ChampionTiger.SetMintContract(address).contrat_addr (#1054) lacks a zero-check on :
- mintContract = contrat_addr (#1056)
Check that the address is not zero.

ChampionTiger._transfer(address,address,uint256) (#1069-1124) uses timestamp for comparisons
Dangerous comparisons:
- botAddresses[sender] && amount > antiBotAmount && antiBotTime > block.timestamp (#1075-1077)
- unlockTime > block.timestamp (#1084)
Avoid relying on block.timestamp.

ChampionTiger.tokensForRewards (#970) is set pre-construction with a non-constant function or state variable:
- MAX_TOKENS_FOR_REWARDS
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.

Pragma version^0.8.2 (#6) allows old versions
solc-0.8.11 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.
