CertiK audits all of Web3, from decentralized applications to the blockchains they’re built on. We work closely with clients to deliver tailor-made security solutions.

Our industry-leading audit methodology and tooling includes a review of your code’s logic, with a mathematical approach to ensure your program works as intended.

Our industry-leading L1 chain auditing process combines expert manual review of smart contract code with advanced AI and mathematical techniques to ensure blockchain protocols work as intended.

CertiK’s speed in execution of audits at scale leaves the competition behind. But don't just take our word for it, listen to what our customers are saying:

Every smart contract audit involves comprehensive manual review by our team of experienced security experts. Automated AI-powered review provides an additional layer of security. Formal verification is an optional further step that certifies smart contract behavior with respect to custom function specifications. This helps developers get a handle on the entire scope of their platform.

How Does a Smart Contract Audit Work?

Every audit involves comprehensive manual review by our team of experienced security experts. Formal verification certifies L1 chain code behavior with respect to custom function specifications, helping developers get a handle on the entire scope of their platform. The process of auditing an L1 is the same as for auditing a smart contract. The five-step process is as follows:

Report an incident if you are under cyber attack and need help!

24/7 Incident Response

An L1 chain audit provides a comprehensive security assessment of a Layer 1 blockchain to identify vulnerabilities and recommend ways to fix them.

CertiK has audited nearly a dozen L1s, along with projects written in all major programming languages, thousands of Web3 projects, and tens of thousands lines of code. As a pioneer in the blockchain security industry, CertiK brings expertise that can only be gained from years of experience with thousands of projects to each and every L1 chain audit.
