X10 Token

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

X10Token.fallback() (#325-348) performs a multiplication on the result of a division:
-tokens = tokensPerOneEther * msg.value / 10 ** 18 (#329)
-valueWei = tokens * 10 ** 18 / tokensPerOneEther (#332)
Consider ordering multiplication before division.

Token._approve(address,address,uint256).owner (#266) shadows:
- Token.owner (#96) (state variable)
Rename the local variables that shadow another component.

Token.changeOwner(address) (#107-109) should emit an event for:
- owner = _owner (#108)
Emit an event for critical parameter changes.

Additional information: link

X10Token.SetPrice(uint256) (#388-390) should emit an event for:
- Price = _price (#389)
Emit an event for critical parameter changes.

Additional information: link

Token.changeOwner(address)._owner (#107) lacks a zero-check on :
- owner = _owner (#108)
Check that the address is not zero.

X10Token.getAirdrop(address) (#369-386) compares to a boolean constant:
-require(bool,string)(AirdropStart == true,Airdrop is not active.) (#372)
Remove the equality to the boolean constant.

Token._mint(address,uint256) (#238-246) is never used and should be removed
Remove unused functions.

Additional information: link

X10Token.balancesOwner (#296) is set pre-construction with a non-constant function or state variable:
- _totalSupply - CrowdSupply - AirDrop
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.

solc-0.8.0 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.

Variable X10Token.PriceChange (#303) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#53)" inContext (#47-56)
Remove redundant statements if they congest code but offer no value.

Reentrancy in X10Token.fallback() (#325-348):
External calls:
- address(msg.sender).transfer(msg.value - valueWei) (#333)
State variables written after the call(s):
- CrowdSupply -= tokens (#338)
- PresaleBalance += msg.value (#339)
- Price -= Price / 100 (#346)
- PriceChange += tokens (#343)
- PriceChange = 0 (#345)
- _balances[msg.sender] += tokens (#336)
- _balances[CrowdAdress] -= tokens (#337)
Event emitted after the call(s):
- Transfer(CrowdAdress,msg.sender,tokens) (#340)
Apply the check-effects-interactions pattern.

X10Token.slitherConstructorVariables() (#287-402) uses literals with too many digits:
- Price = 400000 * 10 ** 18 (#293)
Use: Ether suffix, Time suffix, or The scientific notation

X10Token.aAmt (#292) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

killMe() should be declared external:
- X10Token.killMe() (#397-399)
Use the external attribute for functions never called from the contract.
