Decurity

Decurity is one of the few elite web3 security firms that combines competitive hacking pedigree with deep protocol-level understanding. The team’s services go beyond standard smart contract auditing. Their offerings include full-stack decentralized security: smart contract audits, security advisory, custodial infrastructure testing, risk assessment for investors, invariant-based testing, and real-time exploit detection. This multi-faceted approach ensures that security is not a one-time event but a continuous process.

The company's track record includes audits for leading DeFi protocols like 1inch, Yearn Finance, and Compound. Decurity’s code reviews and penetration testing have led to the discovery of vulnerabilities that prevented real-world financial losses. Additionally, they’ve launched cutting-edge security tools like the ABI Decompiler and Contract Diff for bytecode analysis and smart contract provenance mapping. These tools support auditors and developers alike in building safer dApps.

One of the most innovative products by Decurity is Defimon—a real-time threat detection platform for DeFi protocols. Defimon continuously monitors 50+ protocols for exploit attempts, suspicious transactions, and solvency risks, sending actionable alerts to asset managers, ecosystems, and DeFi projects. This enables proactive defense mechanisms before attacks succeed. Case studies such as the prevention of the Fortress Loans and Sonne Finance exploits highlight the system’s practical impact.

The firm also plays a central role in the global security community, co-hosting competitions like Remedy CTF 2025 with over 2,000 participants, and placing 2nd in the Paradigm CTF 2022 and OpenZeppelin CTF 2024. Through both contribution and leadership, Decurity continues to set benchmarks for modern web3 security practices.

Decurity provides numerous benefits and features that make it a standout project in the blockchain security space:

• Elite Security Talent: Comprised of world CTF champions and top-ranked HackerOne hackers, the Decurity team brings unmatched skill to every audit engagement.
• Full-Spectrum Web3 Coverage: Decurity secures everything from Ethereum smart contracts to Solana Rust programs, Aptos Move contracts, and staking infrastructure, delivering end-to-end protocol safety.
• Live Threat Detection: With the Defimon platform, Decurity monitors real-time attacks across DeFi, offering instant alerts and early exploit detection to prevent financial loss.
• Custom Security Tooling: Tools like ABI Decompiler and Contract Diff enhance audit efficiency, reverse engineering, and contract analysis—helping protocols understand their code lineage and reduce risk.
• Proven Track Record: Projects like 1inch, Compound, Yearn Finance, Giveth, and Gearbox have all benefitted from Decurity’s detailed audits and have avoided or mitigated critical vulnerabilities.
• Investor-Focused Risk Assessments: Tailored security assessments for VC funds, PE firms, and institutional traders ensure smart capital allocation during due diligence processes.
