What is MEV Analyzer?
The MEV Analyzer is a robust command-line interface skill built to empower developers and security researchers in the blockchain space. As a featured part of the Openclaw Skills ecosystem, this tool facilitates a deeper understanding of MEV mechanisms, allowing users to reference on-chain concepts and evaluate the economic security of various decentralized protocols.
By providing a structured environment to log, search, and export MEV-related data, it bridges the gap between raw blockchain noise and actionable intelligence. Whether you are auditing a new smart contract or tracking sandwich attacks, this skill provides the necessary framework to maintain an organized repository of on-chain operations.
MEV Analyzer Use Cases
- Investigating specific MEV mechanisms and their impact on protocol security.
- Maintaining a local database of on-chain entries for historical analysis.
- Exporting processed MEV data for external reporting or further research.
- Generating statistical overviews of captured MEV operations to identify trends.
How MEV Analyzer Works
- Initializing the environment using the status command to ensure the local data directory is ready.
- Capturing and adding new MEV-related entries into the local tracking system.
- Using search and list functions to filter through the database for specific transaction types or protocols.
- Evaluating the health and trends of the collected data via the stats module.
- Exporting the curated dataset to external files for integration with other Openclaw Skills or analytical tools.
MEV Analyzer Setup
To get started with this skill, ensure you have the repository cloned and the script is executable. You can configure your data directory to a custom path using the config command.
# Check current status and initialize
scripts/script.sh status
# Configure a custom data directory
scripts/script.sh config MEV_DIR ~/.custom_mev_path/
# View help for all available commands
scripts/script.sh help
MEV Analyzer Data Schema & Taxonomy
The skill manages information through a structured local file system, primarily governed by the MEV_DIR configuration. Data is organized into entries that can be indexed and queried.
| Variable | Type | Description |
|---|---|---|
MEV_DIR |
Path | The directory where all transaction logs and entries are stored. Defaults to ~/.mev/ |
Entries |
Object | Individual records containing specific MEV operation details, indexed by entry number. |
Config |
Key-Value | Persistent settings that define the behavior of the CLI tool. |
MEV Analyzer Advanced Features
- Custom data directory mapping via
MEV_DIRfor seamless integration into self-hosted lab environments. - Bulk data export capabilities for cross-platform analysis and archival.
- Detailed statistical generation to track MEV frequency and distribution over time.
- Precise entry management allowing for the removal and reorganization of indexed on-chain data.
