Subject: [PATCH] The README.md and application code have been updated to
 include instructions and logging for using a specific RPC without having to
 recompile. This improves usability by allowing users to change the RPC at
 runtime. Also, added log.info to display the endpoint, this can be helpful in
 troubleshooting and ensuring correct configuration.
