What
they say
about us

It was a pleasure working alongside ChainSecurity throughout the audit of our smart contracts and oracles. They maintained clear and direct dialogue with us, and an attention to detail that covered all bases. We look forward to working with them on future solutions to help grow the adoption of DAI.

ChainSecurity was a pleasure to work with, exceptionally easy to coordinate with and delivering an audit of the highest quality. Their meticulous attention to detail truly set them apart, making the entire process smooth and efficient.

We are completely satisfied with this engagement. ChainSecurity team was very flexible about slot booking and provided deep code analysis with non-trivial findings. I’ve asked around about this whole experience and everyone considers your work over the top, thank you so much! ❤️

We continue to be grateful for the comprehensive audits by the ChainSecurity team. Their distinctive understanding of the DeFi space brings an unmatched level of confidence to the audits they employ for us. We are looking forward to continuing working together to bring DeFi forward.

ChainSecurity has been an outstanding security partner who has earned our admiration and respect based purely on their technical competence and skill. They always go above and beyond to ensure their auditing is of the highest quality, and they are consistently excellent over the many projects we have done together.

We appreciate ChainSecurity for their thorough auditing of stUSDT, which has been instrumental in safeguarding our platform’s security. Their expertise in understanding Real-World Assets (RWA), combined with their meticulous approach and insightful feedback, aligns perfectly with our commitment to continually enhance the protocol’s functionality and security.

ChainSecurity demonstrated exceptional professionalism and expertise throughout the audit. They posed insightful and thought-provoking questions, showcasing great attention to detail. Undoubtedly, they are one of the best teams out there.

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.

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 Ltd to anyone looking for top notch secure solutions for blockchains and smart contracts.

ChainSecurity Ltd 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 Ltd produced a detailed report which is public and open for everyone to read. The iExec team would like to thank ChainSecurity Ltd for such a rigorous and detailed report!

When we were evaluating auditors for the Polkadot Claims Contract, the team at ChainSecurity Ltd 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 Ltd again.

ChainSecurity went above and beyond our expectations when it came to the audit of our Liquidations 2.0 upgrade of the MakerDAO Protocol. They were the perfect partner to support the biggest upgrade of the protocol since its launch.

With their thorough and high quality audits, ChainSecurity has been one of Kyber Network’s primary auditors for years now. We look forward to continuing our partnership with them for many more years to come as we keep growing the frontiers of blockchain.

ChainSecurity has a thoughtful and thorough approach to their auditing process, which is not always the case with security auditing firms. Communication was excellent throughout; their high level of scrutiny, attention to detail, and understanding of complexities helped improve our OmniBridge contracts.

The ChainSecurity team went the extra mile to ensure the HOPR token and distributor contracts are secure. They even identified and resolved a complex issue in the ERC777 implementation by OpenZeppelin that's used by many projects in the space.

The entire HOPR team is once again grateful for the highly professional audit by ChainSecurity. Our payment channel and proof-of-relay mechanism is an intricate design that was rapidly understood and evaluated by their auditors, who then delivered an excellent review to help the HOPR community keeping funds in the HOPR payment channels SAFU.

We keep coming back to Chain Security for our protocol and contract audits! Their team is top-notch, delivering comprehensive reviews, fast turnaround, and collaboration from start to finish to ensure our code is of the highest quality and as secure as possible.

The audit process was so much more pleasant and constructive than I imagined - I expected something much more clinical to be honest!
