$CRDN [Cardence] Token

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

Contract ticker ($CRDN) 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.

Token.balanceOf(address)._owner (#191) shadows:
- Ownable._owner (#87) (state variable)
Token.allowance(address,address)._owner (#195) shadows:
- Ownable._owner (#87) (state variable)
Rename the local variables that shadow another component.

Ownable.unlock() (#151-156) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > _lockTime,Contract is locked until 7 days) (#153)
Avoid relying on block.timestamp.

Low level call in Address.sendValue(address,uint256) (#328-334):
- (success) = recipient.call{value: amount}() (#332)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#394-415):
- (success,returndata) = target.call{value: weiValue}(data) (#398)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
