Use Cases

• Validating a private key: By invoking this function with a private key, you can check if the provided private key is valid for Ethereum.

• Checking address validity: The function uses the derived wallet address to determine the validity of the private key.

• Handling errors: If any error occurs during the creation of the wallet or address validation, the function will catch the error and return false, indicating that the private key is not valid.
