$KGC [KishuGrumpyCat] Token

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

Contract ticker ($KGC) 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.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

Context._msgData() (#176-178) is never used and should be removed
Contract.addLiquidity(uint256,uint256,address) (#458-465) is never used and should be removed
Remove unused functions.

Additional information: link

Contract._tTotal (#334) is set pre-construction with a non-constant function or state variable:
- 1000000000000 * 10 ** _decimals
Contract._native (#335) is set pre-construction with a non-constant function or state variable:
- _tTotal
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>0.8.9 (#6) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.12 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.
