+## Slack SR Monitor Tool
+The Slack SR Monitor tool is designed to monitor TRON Super Representatives (SRs) and notify a Slack channel after every maintenance period.
+It automatically tracks vote changes and detects replacements in the top 27 SR positions, providing a clear and formatted report.
+
+### Build and Run the monitor
+To run the monitor tool, you can choose between native Go execution or Docker deployment.
+
+#### Native Go Execution
+Make sure you have Go 1.25+ installed.
+```shell
+# enter the directory
+cd tools/slack_sr_monitor
+# install dependencies
+go mod tidy
+# run the tool
+go run main.go
+```
+
+#### Docker Deployment
+We provide a Docker-based deployment for easier management in production environments.
+```shell
+# build and start the container
+docker-compose up -d --build
+# check logs
+docker logs -f slack-sr-monitor
+```
+
+### Configuration
+All configurations are managed via environment variables or a `.env` file in the project root. Please refer to [.env.example](./.env.example) as an example.
+
+- `SLACK_WEBHOOK`: The Slack Incoming Webhook URL used to send notifications.
+- `TRON_NODE`: The TRON node HTTP API endpoint (e.g., `http://https://api.trongrid.io`). Default is Trongrid.
+
+### Key Features
+
+#### SR vote monitor
+Use `/wallet/getpaginatednowwitnesslist` to get the top **28** real-time votes, also the SR address and URL.
+
+#### Dynamic Scheduling
+Instead of a fixed interval, the tool queries `/wallet/getnextmaintenancetime` to calculate the exact wait time. It triggers the report **1 minute** after each maintenance period begins to ensure data consistency.
+
+#### Parallel Data Acquisition
+The tool uses Go routines to fetch `account_name` for all 28 witnesses in parallel from the `/wallet/getaccount` interface, significantly reducing the collection time.
+
+#### Vote Change Tracking
+The tool maintains an in-memory snapshot of the previous period's votes. It calculates the `Change` for each SR:
+```text
+*1. Poloniex*
+Current: `3,228,089,488`  Change: `+89,488`
+```
+
+#### Top 27 Replacement Detection
+After each report, it compares the current Top 27 list with the previous one and highlights any changes:
+```text
+SR Replacement Detected:
+>:inbox_tray: *Entered:* New_SR_Name
+>:outbox_tray: *Left:* Old_SR_Name
+```
+If no changes occur, it displays `Top 27 SRs remain unchanged.`
+
+### Notifications
+
+This monitor only support java-tron node v4.8.1+, because of the API it used.
