Smart Contract Audit

Smart Contract Audit

Have you created a smart contract? Then use a smart contract audit as a security review conducted by our cybersecurity experts to ensure that the code is free of bugs and security holes.

What is a smart contract audit?

A smart contract audit is a methodical study and analysis of the code of a smart contract that is used to interact with a blockchain. This process is carried out to discover bugs, problems, and vulnerabilities in the code, to suggest improvements and ways to fix them. In general, smart contract audits are necessary as most contracts deal with financial assets and / or valuables.

What should I know about the smart contract audit?

Such tests are complex, as smart contracts often interact with each other and any integration with third-party systems can also make the system vulnerable. Because of this, the audits are often extended to other smart contracts that are involved in interactions, and even those with which they interact. Such reviews typically include both running tests and manual code analysis.

What are we going to do? The process in individual steps

1. Smart contract specification (SCS)

The smart contract audit starts with a smart contract specification. In this first step, we understand the code and the architecture in order to know the desired behavior of the software.

2. Unit tests

Good unit tests are crucial when it comes to developing smart contracts. Since smart contracts are immutable, developing good unit tests is more important for smart contracts than for traditional web and mobile applications.

Unit testing therefore tests each smart contract function against various parameters and conditions to verify that the functions written by the developers work as they should be performed under the intended behavior.

3. Manual code review

We conduct a code inspection line by line to find common vulnerabilities in smart contracts such as race conditions, timestamp dependency, external calls, transaction order and denial-of-service attacks.

4. Automated code analysis

After the manual code review, we also perform an automated code review to uncover additional code errors and security bugs.

5. Reporting

At the final stage we provide a technical and non-technical report with details on weak points and their elimination. This gives you a comprehensive overview of what the next steps in the implementation are to bring a functional smart contract to use.
