Nethermind is a global team of engineers, researchers, and builders working at the core of decentralized systems. Our work spans Ethereum client development, cryptography, formal verification, security research, and developer tooling, with a focus on building infrastructure that is reliable, scalable, and production-ready. We contribute directly to protocol design, open-source software, and applied research, collaborating closely with ecosystem teams to move ideas from research into real-world deployment. Our teams combine deep technical expertise with hands-on experience operating systems at scale, from execution clients and zero-knowledge systems to security audits and developer platforms. Nethermind’s approach is grounded in rigorous engineering, open collaboration, and long-term thinking about the future of decentralized technology.
