SQDAO._tokenTransfer(address,address,uint256,bool).rate (#493) 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.

SQDAO.allowance(address,address).owner (#321) shadows:
- Ownable.owner() (#95-97) (function)
SQDAO._approve(address,address,uint256).owner (#434) shadows:
- Ownable.owner() (#95-97) (function)
Rename the local variables that shadow another component.

Ownable.changeOwner(address) (#107-109) should emit an event for:
- _owner = newOwner (#108)
Emit an event for critical parameter changes.
Additional information: link
Ownable.changeOwner(address).newOwner (#107) lacks a zero-check on :
- _owner = newOwner (#108)
SQDAO.changeRouter(address).router (#587) lacks a zero-check on :
- uniswapV2Pair = router (#588)
Check that the address is not zero.

SQDAO._reflectFee(uint256,uint256) (#547-550) is never used and should be removed
Remove unused functions.
Additional information: link
SQDAO.uniswapV2Pair (#262) is set pre-construction with a non-constant function or state variable:
- _destroyAddress
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.
