Digital Fortress: How Klever Earned Its Place Among the Elite of Blockchain Security

This article is an English adaptation. The original text was published on Eduardo Alex Santos‘s LinkedIn profile.

The Most Valuable Currency in Web3 Is Trust

Since joining Klever and diving deep into the world of blockchain technology, one truth has become increasingly clear to me: the promise of decentralization, empowerment, democratization, and financial freedom can only stand on one unshakable foundation.

In the Web3 ecosystem, the scarcest and most valuable asset isn’t a token; it’s trust. Trust attracts developers to build, users to transact, and entrepreneurs to innovate. Without it, even the most brilliant technology remains just a curiosity.

That’s why today I’m not just here to share news, I’m here to mark a defining milestone in Klever’s journey and, I dare say, an important step forward for the entire ecosystem. With immense pride, I announce that Klever Blockchain has officially earned CertiK Certification, awarded by the most renowned and rigorous security company in the Web3 world.

This isn’t just a stamp of approval; it’s audited, mathematically verified proof of our unwavering commitment to our community’s security. It shows that we’re building our future on a rock-solid foundation. And this achievement goes beyond Klever. It proves that the disruptive innovation of blockchain can coexist with the level of reliability and security that users and institutions, especially in Brazil, not only expect but demand.

Decoding CertiK: The Gold Standard of Blockchain Security

To understand the true significance of this milestone, it’s important to grasp what CertiK represents. Far from being just another auditing firm, CertiK is a security powerhouse born from academic excellence, founded by computer science professors from Columbia University and Yale University. That origin gives CertiK a methodology that goes far beyond a simple code review.

CertiK’s approach is both relentless and comprehensive, applying cutting-edge techniques at the forefront of cybersecurity:

  • Formal Verification: Rather than merely testing for bugs, CertiK uses mathematical proofs to verify the correctness of the code logic, offering a level of assurance traditional testing simply cannot reach.
  • Architecture Analysis & Penetration Testing: Their team performs a full review of system architecture and simulates real-world attacks to test our defenses against the most sophisticated threats.
  • Continuous Monitoring with Skynet: Security is not a one-time event; it’s an ongoing process. CertiK’s Skynet platform continuously monitors over 20 on-chain and off-chain signals, assessing a project’s health in real time.

CertiK’s credibility stems not only from its technical rigor but from its market position. With over $570 billion in market capitalization audited and more than 18,000 projects monitored, CertiK is the trusted auditor for giants like Aave and The Sandbox, and it’s endorsed by leading exchanges such as Binance and OKX.

When a project submits itself to CertiK’s scrutiny, it’s not just checking a box; it’s entering a holistic and continuous security ecosystem. A high score validates more than just code at a point in time; it demonstrates excellence within a dynamic security framework, evaluating everything from technical robustness to operational resilience.

Inside Our Achievement: A Deep Dive into Our 88.02 (AA) Score

With that context in mind, let’s look at the results. Klever achieved an overall score of 88.02, earning the “AA” rating on Skynet. This places us among the top-tier projects that demonstrate exceptional commitment to ecosystem protection.

What fills me with the greatest pride is our Code Security score: an impressive 93.25. This positions Klever Blockchain among the global elite of Web3 projects. Such performance qualifies us for CertiK’s Top 5% Security Score distinction, an honor reserved for projects with the highest security standards and superior code quality.

Being part of this select group is a testament to the talent, precision, and relentless dedication of our engineering team.

In the spirit of full transparency, here’s how our performance breaks down across CertiK’s six main evaluation categories:

Scores collected on October 31, 2025. These values may change over time.

This distribution tells a story of maturity and strategy. Our exceptionally high scores in Code, Market, and Fundamental highlight a robust core product, a transparent team, and a well-positioned project, our true strengths. Meanwhile, our solid results in Governance and Operational (which assess decentralization and incident response) reflect a project that, after solidifying its technological foundation, is now expanding and decentralizing operations as the ecosystem grows.

The message is clear: we first built an impenetrable code fortress; now, on that secure foundation, we expand our reach.

The Real Impact: Building the Future of Web3 on an Unshakable Base

So what does this score mean in practice?

For Developers and Entrepreneurs: Klever Blockchain becomes a safe harbor for innovation. You can build your dApps, DeFi solutions, and tokenization projects knowing that the Layer 1 infrastructure beneath them is rock-solid, removing one of the biggest risks in Web3 development. The energy once spent on baseline audits can now be focused on your business logic and user experience.

For Users and Investors: It means peace of mind. In an industry scarred by multi-billion-dollar hacks, choosing an ecosystem that prioritizes and proves its security is the smartest decision you can make. A CertiK audit is a prerequisite for many informed and institutional investors, and our score places Klever firmly among projects of that caliber.

For the Global Web3 Ecosystem: By investing heavily in a top-tier audit and sharing our results transparently, we’re not just adopting the highest standards; we’re helping raise them, contributing to a culture of responsibility and excellence across the entire sector.

A Brazilian Connection: Innovation and Security in Our DNA

As a Brazilian, I see a powerful parallel between what we’ve achieved and one of the greatest success stories in our country’s tech history: PIX.

PIX is more than just a payment system, it’s a symbol of our ability to innovate quickly, inclusively, and above all, securely. Its massive adoption was made possible by the robust architecture and strict security standards set and enforced by the Central Bank of Brazil (BCB).

Now, the BCB is moving into the next chapter of digital finance with DREX, the digital version of the Real. DREX isn’t just digital money, it’s a blockchain-based infrastructure designed to bring asset tokenization, such as real estate and bonds, into everyday life. Through smart contracts, it enables secure, programmable transactions.

Just like PIX, DREX was born under the BCB’s strict supervision, the central authority that guarantees trust in the system.

In the decentralized world of Web3, however, there is no central authority to enforce such standards. Responsibility lies entirely with the projects themselves. Our decision to voluntarily submit to CertiK’s scrutiny reflects the same “security-first” philosophy that guides the BCB. It’s our way of self-regulation, of holding ourselves to the highest standards to protect our users and earn their trust.

Just as PIX revolutionized payments and DREX will provide a secure backbone for Brazil’s regulated tokenized economy, Klever Blockchain, validated by CertiK, is positioned to become the foundational infrastructure for the new decentralized economy, global, open, and equally secure.

What Comes Next

The next step is the open release of Klever Blockchain’s source code, expanding transparency and community collaboration, a critical function in decentralized networks. We also plan to launch a bug bounty program in partnership with CertiK, inviting ethical hackers and developers to test and strengthen the network even further.

More partner integrations, more developments in Brazil and beyond, more building upon this solid foundation, these are the ingredients that will make Klever not just “a blockchain that passed an audit,” but “a blockchain that stands as global infrastructure, reliable, open, and ready to transform.”

Join Us in Building a Safer Future

This certification is not a finish line; it’s a starting point. It’s the solid foundation upon which we’ll continue to build a richer, more useful, and more secure ecosystem.

This achievement belongs to our entire community. Now that we’ve established this unshakable base of trust, the invitation is open:

If you’re a developer with a bold idea, an entrepreneur ready to build the next great Web3 solution, or an enthusiast who believes in a fairer, more decentralized financial future, the time is now.
