We are extremely pleased with our choice. All the security auditors were great to work with and their services were professionally conducted. I would recommend ChainSecurity to anyone looking for top notch secure solutions for blockchains and smart contracts.

Automated run-time monitoring tool is much needed in this space in addition to all static analysis tools. ChainSecurity Monitoring offers an additional layer of protection to end users and platform operators by helping detect potential malicious or anomaly behaviors on smart contracts early.

Chain Security's service was timely and professional despite given the tight deadline. Their detailed audit report helped us rectify potential problems in our smart contract, and also provided useful recommendations for improvements.

We see that many people are scared of smart contracts, mostly because they aren’t technical enough to understand them and how to use them. ChainSecurity’s auditing tools are a great step forward in helping businesses trust the capabilities of this new technology.

ChainSecurity's platform and experts were extremely helpful in securing BlockV's smart contracts. Thank you for the dedication and fine attention to detail!

ChainSecurity did a supremely thorough job of auditing every aspect of our token contract, going above and beyond by seeing us through to a successful WLK token sale with perfect communications & professionalism and patience to educate along the way. Wolk considers itself lucky to have worked with best in working with ChainSecurity!

We were attracted by the fact that they span out from the security lab at ETH Zurich (Switzerland's answer to MIT). We kept coming back and continue referring them to others for their professionalism and commitment.

When we were evaluating auditors for the Polkadot Claims Contract, the team at ChainSecurity impressed us with their track record of successful audits and their tooling for verifying properties of smart contracts. For the audit, they were able to functionally verify twelve properties of our smart contract to ensure the immutability of critical state that is needed to bootstrap Polkadot genesis. They helped to identify design, trust, and security concerns in the contract and we were able to work together to resolve each of these. If we have further opportunities for our security needs, we would consider engaging ChainSecurity again.

ChainSecurity provided us with a highly professional audit on our smart contract. The impressive track record, reachability and efficiency of the team are big factors for why we would always gladly do another audit with them.

We have repeatedly relied on ChainSecurity’s reviews for our smart contracts managing equity on Ethereum. The reviews have consistently provided us with valuable insights allowing us to go into production with full confidence. The team is highly competent, dedicated and very easy to work with.
Thank you!

While evaluating auditors for the BRIDGE contracts, ChainSecurity demonstrated that they are one step ahead of others with their innovative tooling. They were able to quickly identify various concerns and their availability, openness and deep knowledge simplified our task to find the appropriate fixes. We intend to maintain a long term relationship with ChainSecurity.

We appreciated the high quality 'Swiss approach' of the ChainSecurity team (and of Inacta who developed the Smart Contract): professional; diligent; and responsive. ChainSecurity understood the audit concept that we needed, leveraging the benefits (and accounting for the limitations) of automated testing, and giving us the full benefit of their prior experience with ERC20 token audits.

ChainSecurity provided an expert analysis and audit on each of the iExec V3 smart contracts (mainly the iexecHub and iexecClerk contracts). After an extensive review of thousands of lines of code, ChainSecurity produced a detailed report which is public and open for everyone to read. The iExec team would like to thank ChainSecurity for such a rigorous and detailed report!

Working with the ChainSecurity team was an absolute pleasure, thanks to their thorough approach we have further increased the robustness of our core infrastructure.
