Our solutions

Blockchain Core Engineering

Together with our partners and a global developer community, we support the health and growth of Ethereum and Starknet, building open-source tooling and contributing to network improvements.

Nethermind Research

We are advancing the field of blockchain technology through research in cryptography, decentralized finance (DeFi), and protocol design. By combining theoretical knowledge with practical applications we develop innovative solutions that address challenges faced by decentralized ecosystems.

Nethermind Security

Discover our security services for Ethereum and Starknet applications, spanning smart contract audits, formal verification, and real-time monitoring. Our security researchers have a strong academic background and frequently collaborate on large infrastructure security projects.

dApps & Enterprise Engineering

We cater to a diverse range of clients, from newly established protocols to advanced projects, enterprises, and financial institutions. With expertise in tokenization, Solidity, Cairo, and architectural design, we deliver custom solutions that accelerate DeFi and enterprise blockchain adoption.

Infrastructure Management

We ensure the secure and reliable operation of your blockchain infrastructure. With extensive experience maintaining Ethereum and Lido validators, our team leverages industry best practices and cutting-edge tools to deliver comprehensive node management support.

AI & ZK Engineering

We aim to advance ZK protocols and AI through research, efficient implementations, and practical applications. We’re exploring the potential of AI-supported blockchain systems and collaborate with innovative technologies, such as Starknet and Worldcoin to build a decentralized and privacy-preserving future.

Tooling for the Ethereum & Starknet ecosystems

Our work touches every part of the Ethereum and Starknet ecosystem, from our full nodes to cryptography research and application-layer protocol development.
ethereum contributions

Collaborating to drive Ethereum forward

The Nethermind project was bootstrapped in 2017 and received an Ethereum Foundation grant in 2018 to deliver the full-client implementation. Our unwavering commitment towards strengthening the Ethereum protocol remains strong and we closely align our development and research efforts with its roadmap.

Paprika

A custom database implementation for Ethereum state and storage trees in the Nethermind client. This project aims to set a blueprint for reorganization-aware, checksum-based storage systems.

Libp2p

Libp2p is a modular and future-proof networking stack that addresses P2P protocol limitations. Nethermind is implementing this library in .NET, with the aim of making it available as a public good.

Ethereum Object Format

EOF proposes improvements for the Ethereum Virtual Machine (EVM). Nethermind is one of the first clients to implement EOF, which optimizes Ethereum's performance and offers a more developer-friendly environment.

Account Abstraction

Nethermind, with Ethereum Foundation and OpenGSN, collaborated on EIP-4337 for a user-friendly and decentarlized implementation of account abstraction.

EIP-4844 Shard Blob

Proto-danksharding introduces a transaction format with added data 'blob' space, reducing rollup costs. Nethermind’s implementations of this specification is boosting Ethereum scalability efforts.

Verkle Tree

Our team actively develops and tests the Verkle Tree implementation on Nethermind, collaborating with other Ethereum client teams to ensure a seamless transition from Merkle to Verkle Trees.
