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

Contract locking ether found:
Contract CryptoBattles (contracts/ERC20/CryptoBattles.sol#8-77) has payable functions:
- CryptoBattles.constructor(string,string,uint256) (contracts/ERC20/CryptoBattles.sol#14-23)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

Additional information: link

CryptoBattles.transferFrom(address,address,uint256).fee (contracts/ERC20/CryptoBattles.sol#52) is a local variable never initialized
CryptoBattles.transfer(address,uint256).fee (contracts/ERC20/CryptoBattles.sol#35) 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.

CryptoBattles.constructor(string,string,uint256).name (contracts/ERC20/CryptoBattles.sol#15) shadows:
- ERC20.name() (@openzeppelin/contracts/token/ERC20/ERC20.sol#61-63) (function)
- IERC20Metadata.name() (@openzeppelin/contracts/token/ERC20/extensions/IERC20Metadata.sol#16) (function)
CryptoBattles.constructor(string,string,uint256).symbol (contracts/ERC20/CryptoBattles.sol#16) shadows:
- ERC20.symbol() (@openzeppelin/contracts/token/ERC20/ERC20.sol#69-71) (function)
- IERC20Metadata.symbol() (@openzeppelin/contracts/token/ERC20/extensions/IERC20Metadata.sol#21) (function)
Rename the local variables that shadow another component.

CryptoBattles.constructor(string,string,uint256) (contracts/ERC20/CryptoBattles.sol#14-23) uses timestamp for comparisons
Dangerous comparisons:
- require(bool)(_transferCliffPoint >= block.timestamp) (contracts/ERC20/CryptoBattles.sol#21)
Avoid relying on block.timestamp.

Different versions of Solidity is used:
- Version used: ['^0.8.0', '^0.8.10']
- ^0.8.0 (@openzeppelin/contracts/access/Ownable.sol#3)
- ^0.8.0 (@openzeppelin/contracts/token/ERC20/ERC20.sol#3)
- ^0.8.0 (@openzeppelin/contracts/token/ERC20/IERC20.sol#3)
- ^0.8.0 (@openzeppelin/contracts/token/ERC20/extensions/IERC20Metadata.sol#3)
- ^0.8.0 (@openzeppelin/contracts/utils/Context.sol#3)
- ^0.8.10 (contracts/ERC20/CryptoBattles.sol#3)
Use one Solidity version.

ERC20._burn(address,uint256) (@openzeppelin/contracts/token/ERC20/ERC20.sol#274-289) has costly operations inside a loop:
- _totalSupply -= amount (@openzeppelin/contracts/token/ERC20/ERC20.sol#284)
Use a local variable to hold the loop computation result.

Additional information: link

Context._msgData() (@openzeppelin/contracts/utils/Context.sol#20-22) is never used and should be removed
Remove unused functions.

Pragma version^0.8.0 (@openzeppelin/contracts/access/Ownable.sol#3) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/token/ERC20/ERC20.sol#3) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/token/ERC20/IERC20.sol#3) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/token/ERC20/extensions/IERC20Metadata.sol#3) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/utils/Context.sol#3) allows old versions
Pragma version^0.8.10 (contracts/ERC20/CryptoBattles.sol#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.10 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.

Parameter CryptoBattles.setTransferFee(uint256)._transferFee (contracts/ERC20/CryptoBattles.sol#30) is not in mixedCase
Variable CryptoBattles.BP (contracts/ERC20/CryptoBattles.sol#12) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

CryptoBattles.BP (contracts/ERC20/CryptoBattles.sol#12) should be constant
Add the constant attributes to state variables that never change.
