What we do

Smart Contract Audits

Our security researchers conduct thorough audits specifically tailored to the challenges of the Ethereum and Starknet ecosystems. We are well versed in auditing Solidity and Cairo smart contracts across large infrastructure, DeFi, and FinTech projects. Our cooperative, client-focused approach expedites the smart contract review, improving audit report quality and turnaround time.

AI-Powered Pre-Audits

AuditAgent is a fast, AI-driven pre-audit tool that enhances security workflows with immediate insights, addressing risks early in development. Powered by Nethermind Security & Research, it empowers developers to optimize security in a way that complements traditional audits, providing a strong foundation for comprehensive reviews.

Formal Verification

Nethermind Security provides specialized formal verification in ZK-circuits verification, EVM-based smart contract verification, and Starknet smart contract verification. Our range of services cater to your project's specific needs and include specification drafting, development of property testers, full-stack verification, and the development of advanced automated tools.

Real-Time Monitoring

Our real-time monitoring team designs custom Forta Network detection bots for blockchain protocols. To date, we have engineered and maintained over 200 bots customized for 20 distinct protocols across 7 blockchains and counting. In addition to specializing in Forta bot development and maintenance, we have developed smart contracts for the Forta Network.

Architecture Assessment

Our Architecture Assessment reviews the foundational design of the protocol to uncover weaknesses or inefficiencies not evident in code-level audits. This ensures optimized performance, reduced costs, and a secure, adaptable structure ready for future growth.

Security Assistance

Our security experts provide ongoing support throughout development, ensuring continuous reviews that address vulnerabilities early. This proactive approach minimizes delays and keeps code secure without disrupting speed, allowing for a more resilient final product.
