Hey,
I am worried why ERC 20 is inheriting from IERC20 and IERC20Metadata both. Only IERC20Metadata isn't sufficient as IERC20Metadata is inheriting IERC20 already?
Hello @ABHI_PANCHAL
Inheriting from IERC20Metadata would technically be enough, but for the sake of clarity, we decided to also have it inherit from IERC20. It technically doesn't change anything.
