Hack This Contract is an experimental new site to allow Ethereum developers, auditors, and designers to better understand how to write secure contracts (and exploit insecure contracts). We provide a series of example, vulnerable contracts on the Rinkeby testnet, and encourage developers to exploit their vulnerabilities with their own contracts or techniques. We also provide a leaderboard for developers to rank themselves across the broader security community.

Developers should familiarize themselves with Rinkeby through the tutorial provided on their official website.

We are always soliciting more examples of contracts to add to our challenge database, and encourage contributions to the back-end as well on Github.

Hack This Contract was developed with ♥♥♥ at IC3 Boot Camp by the smart contract security team, and is partially inspired by Hack This Site.
