{Un}Pack - Solidity Smart Contract Analysis Toolkit
[!WARNING] Documentation is under active development!
In the meantime, explore our OpenAPI V3 documentation to understand the capabilities of our system. Full godoc documentation and repository wiki will be available soon.
Overview
{Un}Pack is a robust modular toolkit designed for Solidity smart contract analysis across all EVM-compatible networks.
{Un}Pack toolkit, via JSON-RPC and REST (OpenAPI v3.1.0) is enabling users to decode transactions, logs, decompile opcodes, discover used standards and many more features listed here. Additionally, it offers the ability to search for specific functions and events by their signatures, providing a comprehensive toolkit for in-depth contract analysis and auditing. This enhanced search capability makes it easier for developers to quickly locate and analyze specific smart contracts components.
To manage the storage of large datasets without using Git LFS, we have opted to utilize Cloudflare R2. This object storage solution offers zero egress fees and is a cost-effective alternative to Amazon S3. As a result, the entire dataset is seamlessly integrated with this repository, eliminating the need for you to recreate the datasets independently.
Long story short, clone repo, configure only necessary settings, migrate database, download, decompress and import datasets, start docker containers and enjoy playing with JSON-RPC services!
Features
- Modular design: Easily extend {Un}pack with additional services, configuration or states. See examples module.
- Easy dataset management: Import or export whole dataset with ease. More information can be found here.
- Cloudflare R2 datasets: 7-zip datasets will be hosted on Cloudflare as it's much cheaper than S3 and there are no egress traffic charges!
- Efficient Contract Downloading: Streamlined process for downloading Ethereum smart contracts.
- Download Resumption: Capability to pause and resume downloads, ensuring progress isn't lost.
- Local Storage Management: Stores contracts in Hydra (Postgres) and disk for quick access and efficient retrieval.
- Source Code Access: Provides easy access to the source code of verified contracts on Etherscan, Bscscan, Sourcify.dev and internal Solgo.
- JSON-RPC, REST and GraphQL Support: For easier access to the data, including documentation, postman and OpenAPI v3.1.0 schemas!
- Advanced Decoding Tools: Utilize JSON-RPC and OpenAPI endpoints to decode transactions, logs, decompile opcodes, and attempt ABI recreation of any deployed Ethereum smart contract.
- Signature Search: Enables the searching of functions and events based on their signatures, enhancing the ability to analyze specific contract aspects efficiently.
This project is inspired from Smart Contract Sanctuary. For now, it will be focused only on mainnet contracts. Ethereum is the first one, Arbitrum, Binance Smart Chain and Polygon will be added later including others.
IMPORTANT
- GraphQL endpoint is not yet fully finished.
- Otterscan JSON-RPC api is recommended. We use Erigon and QuickNode.
- For dataset compression we use 7-Zip and XZ compressions.
- If you do not have an Erigon node, you will need to have Etherscan, Bscscan, Arbiscan and/or BitQuery account to get contract creation information.
- Due to licensing issues, we are not going to provide information that strictly breaks licenses. Instead, we are going to provide you the tools to extract information yourself if you have access to the 3rd party sources, utilising their respective API keys.
Datasets
We offer access to a collection of complete datasets, invaluable for researchers, developers, and analysts who require extensive real-world data for their projects.
These datasets are stored on R2, ensuring reliable and speedy access via direct download links.
To avoid spams and malicious use, you would need to reach us over Discord to gain access to the database datasets. In the future, datasets will be available on Cloudflare R2. We are still deciding onto what can be published due to licensing terms.

Documentation (WIP)
Documentation is currently being developed.
Begin your journey at the Welcome. For installation instructions, please consult the Installation guide.

Notes
- For the best performance, it is recommended to run this project on NVMe storage. This is because the database is very large and requires fast read and write to the storage to perform well.
This project is not a new blockchain, due to it, key-value storage is not needed. Even more, it's a problem.
Database Statistics
Bellow is a database overview table, explaining the size of Postgres database as of last database push. This data is only informational and is here to give you a big picture, not the most accurate database size (as it changes from second to second).
