Contract Security Checks

Due to the nature of distributed apps it is very hard to fix bugs once the application is deployed. Hence, it is of great importance to ensure the app is running correctly and securely before deployment. Contract security reviews are done by specialised companies. They can be very costly which might be out of reach for single developers and start-ups. However, there are also automated services and programs that are free to use. The most popular are:

• ​Slither, here's a tutorial​

• ​MythX​

• ​Mythril​

We recommend using at least one of these services if a professional contract security review is unaffordable or not possible. A more comprehensive look into secure development practices can be found here.
