xavieraTech.finalizeTransfer(address,address,uint256,bool).checked (#378) is a local variable never initialized
xavieraTech.finalizeTransfer(address,address,uint256,bool).check (#379) 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.

Additional information: link

xavieraTech.finalizeTransfer(address,address,uint256,bool) (#370-388) ignores return value by antiSnipe.checkUser(from,to,amount) (#379-380)
Ensure that all the return values of the function calls are used.

Additional information: link

xavieraTech.setOperator(address).newOperator (#199) lacks a zero-check on :
- operator = newOperator (#205)
Check that the address is not zero.

Additional information: link

xavieraTech.finalizeTransfer(address,address,uint256,bool) (#370-388) has external calls inside a loop: antiSnipe.checkUser(from,to,amount) (#379-380)
Favor pull over push strategy for external calls.

Additional information: link

Variable 'xavieraTech.finalizeTransfer(address,address,uint256,bool).check (#379)' in xavieraTech.finalizeTransfer(address,address,uint256,bool) (#370-388) potentially used before declaration: checked = check (#380)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

Pragma version>=0.6.0<0.9.0 (#2) is too complex
solc-0.8.16 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.

transfer(address,uint256) should be declared external:
- xavieraTech.transfer(address,uint256) (#227-230)
enableTrading() should be declared external:

Use the external attribute for functions never called from the contract.
