The exercises/exercise2/coin.sol file contains an access control implementation with the
onlyOwner modifier. A common mistake is forgetting to add the modifier to a crucial function. In this exercise, we will use Slither to implement a conservative access control approach.
Our goal is to create a script that ensures all public and external functions call
onlyOwner, except for the functions on the whitelist.
Create a whitelist of signatures Explore all the functions If the function is in the whitelist of signatures: Skip If the function is public or external: If onlyOwner is not in the modifiers: A bug is found
