Smart Contract Audit & Security Testing

Decurity delivers deep manual smart contract security reviews for Ethereum Solidity, Solana Rust, and Aptos Move contracts as well as decentralized applications (dApps). Conducted by CTF world champions and HackerOne top-50 ranked hackers, audits go beyond automated scanning to uncover novel attack vectors and critical vulnerabilities before protocol deployment.

Audit Process

Each engagement involves thorough manual review of all contract source code, identification of critical, high, medium, and low severity vulnerabilities, analysis of business logic flaws specific to DeFi mechanics, and a final report with detailed findings and recommended remediations. Audit clients include 1inch, Yearn Finance, Gearbox Protocol, Compound, Optimism, Scroll, Metis, and PancakeSwap.

Invariant Testing & Fuzzing

Decurity also offers invariant development as a complementary layer of assurance. This involves formally identifying smart contract invariants — conditions that must always hold true — and executing fuzzing campaigns using Echidna, Medusa, and Foundry's invariant testing to aggressively probe for violations. End-to-end integration testing covers complex multi-transaction sequences, cross-contract interactions, and realistic DeFi usage patterns.

Ongoing Audit Coverage

For protocols with active development cycles, Decurity's Security Advisory engagement includes periodic security reviews as new features are deployed, ensuring code changes receive security scrutiny on a continuous basis.
