In blockchain, security isn’t optional—it’s expected. With smart contracts handling millions in value, the need for reliable, independent code audits has never been greater. CertiK has emerged as one of the most recognized names in this space, helping projects identify risks before they turn into losses.
What Is CertiK?
CertiK is a leading blockchain security firm focused on protecting decentralized systems through advanced auditing and monitoring services. It specializes in analyzing the source code of smart contracts, decentralized applications (dApps), Layer 1 and Layer 2 protocols, and other blockchain infrastructures before they are deployed on-chain.
Founded in 2018 by computer science professors Dr. Ronghui Gu (Columbia University) and Professor Zhong Shao (Yale University), CertiK applies formal verification methods—a mathematical approach used to prove the correctness of code logic—and artificial intelligence to detect vulnerabilities, logic errors, and potential exploits in blockchain systems.
CertiK’s services include:
- Smart Contract Audits: In-depth code analysis to identify bugs, logic flaws, and security gaps.
- Skynet: A real-time monitoring tool that evaluates on-chain activity, governance behavior, code changes, and social sentiment, providing dynamic security scores for audited projects.
- KYC (Know Your Customer) Verification: Identity checks for project teams to add a layer of accountability and reduce the risk of fraud.
- Penetration Testing and Formal Verification: Simulated attacks and mathematical proof techniques to test resilience against real-world threats.
Projects across multiple chains—Ethereum, BNB Chain, Polygon, Solana, and others—use CertiK to build trust with users and investors. Some of the most prominent DeFi protocols, crypto wallets and token launches in recent years have relied on CertiK audits as part of their go-to-market strategy.
In an industry where code is law, CertiK plays a crucial role in preventing financial loss, increasing transparency, and setting higher standards for project accountability.
A CertiK audit doesn’t eliminate all risk, but it is a widely recognized signal that a project has taken the minimum steps to secure its smart contracts and protect its users.
Why CertiK Matters
- Trust and Transparency
In the decentralized space, trust is often algorithmic, and security audits serve as a proxy for legitimacy. A CertiK audit shows that a project has taken significant steps to protect users and assets. - Risk Mitigation
CertiK helps projects identify and eliminate vulnerabilities before attackers can exploit them. This is critical in an environment where billions of dollars have been lost to DeFi hacks and rug pulls. - Investor Confidence
Projects with CertiK audits tend to attract more users, partners, and institutional attention. For many investors, an audit from CertiK is a baseline requirement before committing funds. - Security Ratings and Continuous Monitoring
Tools like CertiK Skynet offer ongoing evaluations of a project’s health, monitoring wallet behavior, governance risks, code updates, and market sentiment. This real-time visibility is crucial for early detection of suspicious activities. - Standardization
CertiK contributes to industry-wide best practices, pushing the ecosystem toward more robust and reliable codebases, which is essential for mass adoption.
Klever Wallet Core (KOS) Audited by CertiK
The core infrastructure of Klever Wallet — KOS (Klever Operating System) — has been officially audited by CertiK, a globally trusted name in blockchain security.
While KOS is open source, this independent verification adds an extra layer of transparency and trust. The audit confirmed the security and integrity of critical components that power self-custody inside Klever Wallet.
CertiK validated the processes for mnemonic generation, entropy strength, signing implementations, and confirmed that private keys are never exposed or leaked.
By certifying how Klever handles these sensitive operations, CertiK recognizes the platform’s secure approach to non-custodial asset management. This reinforces Klever’s commitment to empowering users with full control over their funds — secure, transparent, and independently verified.
A Milestone for Klever and Web3
The CertiK certification of KOS marks a significant achievement for Klever Wallet and a meaningful contribution to the Web3 space. It reinforces Klever’s role in setting higher security standards for non-custodial wallets, where users maintain full control over their assets.
In an industry where many platforms still compromise on transparency or rely on custodial models, Klever’s open-source foundation and now independently audited core highlight a clear commitment to self-sovereignty and trustless infrastructure.
For users, it means stronger confidence in the technology they rely on.
For the ecosystem, it’s a step forward in proving that user-controlled finance can also be secure, auditable, and professionally validated.
This milestone strengthens not only Klever’s position—but the credibility of self-custody solutions across Web3.
