OKEY [OKEYCOIN] Token

OKEYCOIN.withdrawToken(address,uint256) (#1563-1567) ignores return value by tokenContract.transfer(msg.sender,_amount) (#1566)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

OKEYCOIN._rTotal (#883) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))

Pragma version0.8.10 (#4) 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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#415-443):
- (success,returndata) = target.call{value: weiValue}(data) (#424-426)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
