Magical Blocks security record

In the function `transferFrom()`, the `msg.sender` will be checked in the blacklist or not. However, the address `from` is not checked. According to the logic of the function `transfer`, the user in the blacklist cannot transfer his/her own tokens. But he/she can bypass this restriction via the function `transferFrom`, by approving the allowance to others.

The functions which are never called internally within the contract should have external visibility for gas optimization. ```solidity=132 function updatePercentageDecimals(uint256 newPercentageDecimals_)public onlyOwner{ ``` --- ```solidity=136 function updateSupportedChains(uint256[]memory chainIds_,bool[]memory chainStatus_)public onlyOwner{ ``` --- ```solidity=140 function pause() public onlyOwner { ``` --- ```solidity=144 function unpause() public onlyOwner { ``` --- ```solidity=19 function mint(address account_, uint256 amount_)public whenNotPaused onlyAdmin{ ``` --- ```solidity=25 function burn(uint256 amount_)public whenNotPaused{ ``` --- ```solidity=31 function blacklistUpdate(address user, bool value) public onlyOwner { ``` --- ```solidity=37 function transfer(address recipient, uint256 amount) public whenNotPaused override(ERC20,IERC20) returns (bool) { ``` --- ```solidity=43 function transferFrom(address from,address to,uint256 amount) public whenNotPaused virtual override(ERC20,IERC20) returns (bool) { ``` --- ```solidity=19 function init(address bezogeToken_, address zogiToken_, uint256 minWrapAmount_, ``` --- ```solidity=34 function wrapBezoge(uint256 amount_)public { ``` --- ```solidity=49 function unWrapBezoge(uint256 amount_)public { ```
