CertiK works on security for blockchain projects. Its core service is the audit, in which engineers and automated tools review a project’s smart contract code to find bugs, logic mistakes, and vulnerabilities before funds are at risk. Audit reports are often published, and projects display them to build trust with users.
Beyond audits, CertiK offers monitoring and scoring. Its Skynet platform tracks security signals and rates projects, and it provides alerts, wallet and transaction analysis, and tools for investigating hacks. Bug bounty programs and penetration testing add other layers, and it also offers formal verification for high-assurance contracts.
CertiK sells to crypto companies on a project basis, and an audit is not a guarantee. Audited projects have still been exploited, and ratings are not investment advice. Competitors include OpenZeppelin, Trail of Bits, Hacken, Quantstamp, and Halborn. CertiK suits blockchain teams that need external security review.
