Technoland.finalizeTransfer(address,address,uint256,bool,bool,bool).check (#569) 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.

Technoland.finalizeTransfer(address,address,uint256,bool,bool,bool) (#560-585) ignores return value by antiSnipe.checkUser(from,to,amount) (#569-570)
Ensure that all the return values of the function calls are used.

Emit an event for critical parameter changes.

Technoland.setOperator(address).newOperator (#254) lacks a zero-check on :

Check that the address is not zero.

Technoland.finalizeTransfer(address,address,uint256,bool,bool,bool) (#560-585) has external calls inside a loop: antiSnipe.checkUser(from,to,amount) (#569-570)
Favor pull over push strategy for external calls.

Variable 'Technoland.finalizeTransfer(address,address,uint256,bool,bool,bool).check (#569)' in Technoland.finalizeTransfer(address,address,uint256,bool,bool,bool) (#560-585) potentially used before declaration: checked = check (#570)
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.
