Token.constructor(string,string).name (Token.sol#29) shadows:
- ERC20.name() (ERC20.sol#62-64) (function)
- IERC20Metadata.name() (IERC20Metadata.sol#17) (function)
Token.constructor(string,string).symbol (Token.sol#29) shadows:
- ERC20.symbol() (ERC20.sol#70-72) (function)
- IERC20Metadata.symbol() (IERC20Metadata.sol#22) (function)
Rename the local variables that shadow another component.

Token.updateRewardWalletLimit(uint256) (Token.sol#40-42) should emit an event for:
- limitTxForRewardWallet = newLimitation (Token.sol#41)
Emit an event for critical parameter changes.

Additional information: link

Token.updateRewardWallet(address).newWallet (Token.sol#37) lacks a zero-check on :
- rewardWallet = newWallet (Token.sol#38)
Token.setRewardsPool(address)._rewardsPool (Token.sol#80) lacks a zero-check on :
- rewardsPool = _rewardsPool (Token.sol#81)
Check that the address is not zero.

Token._transfer(address,address,uint256) (Token.sol#85-112) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(lastTrade[sender] < (block.timestamp - tradeCooldown),string(No consecutive sells allowed. Please wait.)) (Token.sol#99)
Avoid relying on block.timestamp.

Additional information: link

Token._transfer(address,address,uint256) (Token.sol#85-112) compares to a boolean constant:
-liquidityPool[receiver] == true (Token.sol#95)
Token._transfer(address,address,uint256) (Token.sol#85-112) compares to a boolean constant:
-liquidityPool[sender] == true (Token.sol#92)
Remove the equality to the boolean constant.

Context._msgData() (Context.sol#21-23) is never used and should be removed
ERC20._burn(address,uint256) (ERC20.sol#275-290) is never used and should be removed
Remove unused functions.
