Oyente======An Analysis Tool for Smart Contracts[![Gitter][gitter-badge]][gitter-url][![License: GPL v3][license-badge]][license-badge-url]## Quick StartA container with the dependencies set up can be found [here](https://hub.docker.com/r/luongnguyen/oyente/).To open the container, install docker and run:```docker pull luongnguyen/oyente && docker run -i -t luongnguyen/oyente```To evaluate the greeter contract inside the container, run:```cd /oyente/oyente && python oyente.py -s greeter.sol```and you are done!Note - If need the [version of Oyente](https://github.com/melonproject/oyente/tree/290f1ae1bbb295b8e61cbf0eed93dbde6f287e69) referred to in the paper, run the container from [here](https://hub.docker.com/r/hrishioa/oyente/)## InstallationInstall Oyente via pip:```You can't use 'macro parameter character #' in math modeYou can't use 'macro parameter character #' in math mode sudo add-apt-repository ppa:ethereum/ethereumsudoapt−getupdate sudo apt-get install solc```#### evm from [go-ethereum](https://github.com/ethereum/go-ethereum)1. https://geth.ethereum.org/downloads/ or2. By from PPA if your using Ubuntu```sudoapt−getinstallsoftware−properties−common sudo add-apt-repository -y ppa:ethereum/ethereumsudoapt−getupdate sudo apt-get install ethereum```#### [z3](https://github.com/Z3Prover/z3/releases) Theorem Prover version 4.5.0.Download the [source code of version z3-4.5.0](https://github.com/Z3Prover/z3/releases/tag/z3-4.5.0)Install z3 using Python bindings```pythonscripts/mkmake.py−−python cd buildmake sudo make install```#### [Requests](https://github.com/kennethreitz/requests/) library```pip install requests```#### [web3](https://github.com/pipermerriam/web3.py) library```pip install web3```### Evaluating Ethereum Contracts```#evaluate a local solidity contractpython oyente.py -s <contract filename>#evaluate a local solidity with option -a to verify assertions in the contractpyhon oyente.py -a -s <contract filename>#evaluate a local evm contractpython oyente.py -s <contract filename> -b#evaluate a remote contractpython oyente.py -ru https://gist.githubusercontent.com/loiluu/d0eb34d473e421df12b38c12a7423a61/raw/2415b3fb782f5d286777e0bcebc57812ce3786da/puzzle.sol```And that's it! Run ```python oyente.py --help``` for a list of options.## PaperThe accompanying paper explaining the bugs detected by the tool can be found [here](http://www.comp.nus.edu.sg/~loiluu/papers/oyente.pdf).## Miscellaneous UtilitiesA collection of the utilities that were developed for the paper are in `misc_utils`. Use them at your own risk - they have mostly been disposable.1. `generate-graphs.py` - Contains a number of functions to get statistics from contracts.2. `get_source.py` - The *get_contract_code* function can be used to retrieve contract source from [EtherScan](https://etherscan.io)3. `transaction_scrape.py` - Contains functions to retrieve up-to-date transaction information for a particular contract.## BenchmarksNote: This is an improved version of the tool used for the paper. Benchmarks are not for direct comparison.To run the benchmarks, it is best to use the docker container as it includes the blockchain snapshot necessary.In the container, run `batch_run.py` after activating the virtualenv. Results are in `results.json` once the benchmark completes.The benchmarks take a long time and a *lot* of RAM in any but the largest of clusters, beware.Some analytics regarding the number of contracts tested, number of contracts analysed etc. is collected when running this benchmark.## ContributingCheckout out our [contribution guide](https://github.com/melonproject/oyente/blob/master/CONTRIBUTING.md) and the code structure [here](https://github.com/melonproject/oyente/blob/master/code.md).[gitter-badge]: https://img.shields.io/gitter/room/melonproject/oyente.js.svg?style=flat-square[gitter-url]: https://gitter.im/melonproject/oyente?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge[license-badge]: https://img.shields.io/badge/License-GPL%20v3-blue.svg?style=flat-square[license-badge-url]: ./LICENSE
