In refactoring the determine_chain_endpoint_and_network method, the following changes were made to streamline and optimize the code:

1. Optional Type Hint for network Argument: I used Optional[str] for the network parameter to explicitly indicate that it can be None. This improves type safety and clarity.

2. Simplified Logic with Dictionary Mappings: I introduced two dictionaries:

• endpoints maps network names to their endpoints.

• reverse_endpoints is a reversed mapping of endpoints, mapping endpoints back to network names.

This structure simplifies the original series of if-else statements, making it easier to understand and maintain. By using these mappings, the function can quickly look up the network name or endpoint without going through multiple conditional checks.

3. Consolidated Return Statements: The original code had separate return statements for each condition, which made it somewhat repetitive. By mapping network names to endpoints (and vice versa), only a few conditional checks are needed to determine the appropriate return values, streamlining the function.

4. Handling Edge Cases with a Single Conditional Block: For specific URL parts that identify a network ("entrypoint-finney.opentensor.ai", "test.finney.opentensor.ai", "archive.chain.opentensor.ai"), I used conditional checks within the same framework without separately identifying them as in the original code. This approach reduces redundancy.

5. Use of Tuple for Return Type: The return type is explicitly defined as a tuple of two optional strings, Tuple[Optional[str], Optional[str]], enhancing the function's readability and type clarity.

6. Default Return Value for Unknown Network: If none of the conditions match, the function defaults to returning "unknown", network, ensuring that there's always a clear output regardless of input validity.

In refactoring the setup_config method, the following changes were made to streamline and optimize the code:

1. Simplified Logic Flow: The original code contained repetitive blocks checking different conditions to determine the network and chain endpoint. These checks were consolidated into a single line by using a logical progression to determine the network_source. This approach checks for network, config.subtensor.chain_endpoint, config.subtensor.network, and falls back to bittensor.defaults.subtensor.network if none are specified, effectively covering all original conditions in a more compact form.

2. Unified Endpoint and Network Determination: The original code performed the same operation (subtensor.determine_chain_endpoint_and_network) multiple times under different conditions. By determining the network_source first and then calling determine_chain_endpoint_and_network once, it reduces redundancy and improves readability.

3. Direct Return of Formatted URL and Network: After determining the evaluated_network and evaluated_endpoint, the method directly formats the endpoint URL and returns it along with the network name. This approach minimizes the temporary variables and streamlines the return statement.

4. Use of Optional Type: The type hint for network in the method signature was updated to Optional[str] to explicitly indicate that network can be None. This adjustment improves code clarity regarding the function's expected input types.

5. Eliminated Unnecessary Conditionals: By restructuring the logic, unnecessary conditionals that checked various config properties separately were removed. This not only simplifies the code but also ensures that it's easier to follow and maintain.

These changes aim to improve the function's efficiency, readability, and maintainability while preserving its original functionality.
