Crystal-Clear CLI: Smart Contract Supply Chain 🔗
Analyze and visualize Ethereum smart contract dependencies with ease. SCSC helps you understand contract interactions by generating detailed call graphs from on-chain data.
✨ Features
- 📊 Generate comprehensive call graphs from smart contract interactions
- 🔍 Analyze contract dependencies across specified block ranges
- 📈 Export visualizations in DOT format for further analysis
- ⚙️ Flexible configuration options for node connections and logging
🚀 Quick Start
Prerequisites
- Python 3.12 or higher
- Access to an Archive Ethereum node (local or remote)
- Allium API access: optional, used to enrich addresses with labels
- Etherscan API access: required for retrieving verified smart contract source code
- Poetry
Installation
# Clone the repository
git clone https://github.com/mab-xyz/crystal-clear.git
cd crystal-clear/webapp/backend/crystal-clear
# Install with Poetry
poetry install
# Activate the environment
poetry shell
💻 Usage
Crystal-Clear CLI provides two main commands:
1. Analyze Dependencies Command
Dependency Graph
# note the RPC node must have method trace_filter
crystal-clear dependency --node-url <node_url> \
--address <contract_address> \
--from-block <block> \
--to-block <block> \
[options]
# this exports the smart contract dependency graph
crystal-clear dependency --node-url <node_url>
--address 0xE592427A0AEce92De3Edee1F18E0157C05861564 \
--from-block 0x14c3b86 \
--to-block 0x14c3b90 \
--export-dot graph.dot
Risk analysis per contract (computes the risk factors, incl. proxy and permission risks)
You can select the scope of the analysis:
single– assesses the risk of the specified contract only.supply-chain– assesses the risk of the contract and all dependent contracts in its supply chain.
crystal-clear risk --etherscan-api-key <etherscan_api> \
--node-url <node_url> \
--scope [single|supply-chain]
--address <contract_address> \
[options]
crystal-clear risk
--address 0xE592427A0AEce92De3Edee1F18E0157C05861564 \
--scope single
--export-json analysis.json
