Blockchain Security That Actually Works
We've been tracking vulnerabilities since 2019, back when most people thought smart contracts were just fancy databases. Our team has prevented over $180M in potential losses through systematic security analysis.
How We Approach Security Auditing
Code Architecture Review
We start with the big picture. Most vulnerabilities aren't in individual lines of code — they're in how different components interact. Last month, we caught a critical flaw in a DeFi protocol where the staking mechanism could be exploited through price oracle manipulation. The individual functions looked fine, but together they created a $50M risk.
Automated Vulnerability Scanning
Our custom scanning tools go beyond standard static analysis. We've built detection algorithms specifically for common DeFi attack patterns — flash loan exploits, sandwich attacks, MEV vulnerabilities. But automation is just the starting point. Real security comes from understanding context that machines miss.
Manual Penetration Testing
This is where experience matters. We simulate actual attack scenarios using the same tools and techniques as malicious actors. Our team maintains active research on emerging attack vectors — we often identify new exploit methods before they appear in the wild.
Business Logic Verification
Code can be technically secure but economically exploitable. We analyze tokenomics, governance mechanisms, and incentive structures. Some of the biggest protocol failures come from economic design flaws, not coding errors.
Specialized Security Services
Each blockchain ecosystem has unique risks. We've developed specialized testing approaches for different protocols and use cases.
Smart Contract Auditing
Complete security analysis for Ethereum, Binance Smart Chain, Polygon, and Avalanche contracts. We focus on gas optimization attacks, reentrancy vulnerabilities, and access control flaws that automated tools often miss.
DeFi Protocol Testing
Specialized testing for lending protocols, AMMs, yield farming contracts, and cross-chain bridges. We understand the complex interactions between liquidity pools, oracle feeds, and governance tokens that create unique attack surfaces.
NFT Platform Security
Security evaluation for NFT marketplaces, minting contracts, and royalty systems. We've identified vulnerabilities in several major platforms that could have allowed unauthorized minting or royalty bypass.
Cross-Chain Bridge Analysis
Comprehensive security assessment for cross-chain infrastructure. Bridge protocols have unique risks from consensus mechanism differences and asset wrapping vulnerabilities that require specialized testing approaches.
Security Findings That Matter
In early 2025, we identified a critical vulnerability in a popular yield farming protocol that could have been exploited during high gas fee periods. The attack would have been profitable only when network congestion created specific conditions — exactly the kind of context-dependent risk that standard audits miss.

- Helped 40+ protocols improve their security posture
- Maintained 100% detection rate for critical vulnerabilities
- Contributed to industry-wide security standard improvements
Security Experts You Can Trust
Our team combines deep technical knowledge with practical experience from both security research and protocol development.
Dorian Kjelstad
Lead Security Engineer
Former blockchain developer who found more bugs in his own code than anyone else. Now he applies that same critical eye to other people's smart contracts. Discovered three major vulnerabilities in top DeFi protocols during 2024.
Elisabet Varga
Penetration Testing Specialist
Spent five years breaking traditional web applications before moving to blockchain security. She thinks like an attacker because she used to be one — ethically, of course. Her methodology has become our standard approach for manual testing.
Branko Petrovic
DeFi Security Analyst
Economics PhD who got fascinated by the game theory aspects of DeFi protocols. He's the guy who spots the economic vulnerabilities that purely technical audits miss. Prevented two major governance attacks in 2024 through economic analysis.
Our distributed team works from Vietnam, but serves clients globally. We maintain 24/7 monitoring capabilities and can respond to security incidents across different time zones. Most of our process happens asynchronously, which actually improves audit quality — fresh eyes catch more problems.
Ready to Secure Your Protocol?
We typically start new audit engagements 3-4 weeks out, depending on complexity. Early 2025 is booking up quickly as more protocols prepare for mainnet launches and major updates.
