CMAS [Cryptmas] Token

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

Contract ownership is not renounced (belongs to a wallet)

CRYPTMAS.allowance(address,address).owner (#545) shadows:
- Ownable.owner() (#456-458) (function)
CRYPTMAS._approve(address,address,uint256).owner (#626) shadows:
- Ownable.owner() (#456-458) (function)
Rename the local variables that shadow another component.

solc-0.6.2 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.

Low level call in Address.sendValue(address,uint256) (#331-337):
- (success) = recipient.call{value: amount}() (#335)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#397-418):
- (success,returndata) = target.call{value: weiValue}(data) (#401)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
