SCSC

Analyzing the smart contract supply chain.

Prerequisites

  • Python 3.7 or higher
  • An Ethereum node (e.g., Geth, Parity) running and accessible via HTTP

Installation

1. Clone the Repository

First, clone the repository to your local machine:

git clone https://github.com/chains-project/scsc.git
cd scsc

2. Set Up a Virtual Environment (Optional but Recommended)

It's recommended to use a virtual environment to manage dependencies:

python -m venv venv
source venv/bin/activate

3. Install Dependencies

Install the required Python packages using pip:

pip install -r requirements.txt

4. Configure the Project

Edit the config.py file to set your Ethereum node URL:

# config.py

ETHEREUM_NODE_URL = 'http://localhost:8545'

Usage

Single contract supply chain

Computes the supply chain of a smart-contract at a given block (or over a block period TODO)

python scsc.py [--block <block_number>] [--offset <blocks_offset>] --address <contract_address> [--calls]

<block_number>: Block number that is analyzed. When not provided, assumes the latest block number of Ethereum Mainnet.

<blocks_offset>: The number of blocks before <block_number> that are also analyzed. When not provided, assume the value 0.

--calls: flag that outputs the call trees of each transaction that was analyzed

Future feature - Export to machine readable format:

./scsc --json  --block 1234 --address 0xabcdef012345678 (TODO)

Contract graph

./scsc --graph --from-block 1234 --to-block 2234  --output graph.dot

TODO: explain the medadata available on the graph (supplier, mutable, vulnerable, ...)
