# Nethermind > Building blocks for the decentralized future Nethermind builds software for Ethereum and Starknet networks, including execution clients, node tools, and blockchain explorers. Nethermind is an Ethereum execution client built on .NET that delivers performance in syncing and tip-of-chain processing. It creates execution clients, node management solutions, and data access services. Nethermind also provides security services and AI tools for blockchain applications. - Type: Company - Sector: Infrastructure - Status: Active - Founded: 2017-08-01 - Profile: https://thegrid.id/profiles/nethermind ## Products - [Nethermind Ethereum Client](https://thegrid.id/profiles/nethermind): Nethermind Ethereum Client is an Ethereum execution client built on .NET that processes transactions and maintains the blockchain state. It supports multiple networks and provides JSON-RPC endpoints for developers and operators. (Node Software, Live, Main Product) - [Juno](https://thegrid.id/profiles/nethermind): Juno is a Starknet full-node client written in Go that synchronizes state, processes transactions, and verifies blocks against Ethereum. It aims to decentralize Starknet by providing an alternative to the official client. (Node Software, Live) - [Sedge](https://thegrid.id/profiles/nethermind): Sedge is a one-click setup tool for PoS network/chain validators and nodes that helps with the configuration and deployment of validators for Ethereum and other networks. (Developer Tooling, Live) - [Nine](https://thegrid.id/profiles/nethermind): Nethermind Intelligent Nodes Environment (Nine) is a framework for AI agents that allows distributed deployment and interfaces across environments. (AI Agent Framework, Live) - [AuditAgent](https://thegrid.id/profiles/nethermind): AuditAgent is a smart contract security tool that identifies vulnerabilities using AI and static analysis. It generates reports and suggests fixes for code issues. (Blockchain Development Security Tools, Live) - [starknet.go](https://thegrid.id/profiles/nethermind): starknet.go is a Golang library for Starknet and Cairo that allows developers to interact with the Starknet network, submit transactions, and call smart contracts from Go applications. (Developer Tooling, Live) - [Starkweb](https://thegrid.id/profiles/nethermind): StarkWeb is a TypeScript library that connects applications to the Starknet blockchain. It provides interfaces for data retrieval, transaction submission, and smart contract interaction. (Developer Tooling, Live) - [Nethermind Security](https://thegrid.id/profiles/nethermind): Nethermind Security performs smart contract security assessments through static and dynamic code analysis techniques, detecting vulnerabilities in Solidity and Cairo implementations. (Smart Contract Audits, Live) - [Horus](https://thegrid.id/profiles/nethermind): Horus implements automated formal verification through SMT solving, enabling Cairo smart contract verification before deployment. The system translates specification annotations into mathematical assertions while maintaining compatibility with StarkNet development workflows. (Developer Tooling, Inactive/Support Ended) - [Warp](https://thegrid.id/profiles/nethermind): Warp implements Solidity-to-Cairo transpilation through AST transformation, enabling Ethereum smart contract deployment on Starknet. The system converts Solidity bytecode to Cairo equivalents while maintaining contract functionality and facilitating cross-ecosystem migration workflows. (Developer Tooling, Inactive/Support Ended) - [Clear](https://thegrid.id/profiles/nethermind): Clear is a formal verification framework for Solidity smart contracts that translates Yul programs into the Lean proof assistant for computer-checkable correctness proofs. It enables developers to mathematically prove contract behavior against formal specifications.
