Practical overview

When it fits

Use Nethermind when you need to operate an Ethereum execution client, connect infrastructure through JSON-RPC, or extend node capabilities without forking the core codebase.

Who it is for

  • Ethereum node operators
  • Teams building blockchain infrastructure
  • Developers extending an execution client through plugins
  • Operators working with supported EVM networks and L2 systems

Documented uses

  • Run a self-hosted Ethereum execution node.
  • Expose Ethereum execution through JSON-RPC over HTTP, WebSocket or IPC.
  • Monitor node health and performance using the built-in UI and Prometheus metrics.
  • Extend client behavior with plugins.
  • Build or operate infrastructure for supported L2 networks.
Before you choose

Requirements & limits

The repository is public and licensed under GPL-3.0. Documented installation paths include standalone releases, Linux packages, Windows Package Manager, Homebrew, Docker and source builds.

  • Choose the deployment path that matches the environment: Linux, Windows, macOS, Docker or source build.
  • Review documented system requirements before operating a node.
  • The client exposes JSON-RPC over HTTP, WebSocket and IPC.
  • Plugin support allows additions such as consensus engines, transaction types, P2P handlers and RPC namespaces without modifying the core.
  • Teams migrating from Geth can use the same JSON-RPC API, according to the project documentation.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Build Nethermind from source as a standalone binary

Clone the repository, build the release configuration and run the mainnet client.

Before you start

  • A .NET SDK version 10 or later.
  • Access to the Nethermind GitHub repository.

Steps

  1. Clone the repository recursively with the command below.

    Documented command
    git clone --recursive https://github.com/nethermindeth/nethermind.git

  2. Change to nethermind/src/Nethermind/Nethermind.Runner.

  3. Run dotnet run -c release -- -c mainnet.

  4. Optionally run the documented Nethermind and Ethereum Foundation test suites from nethermind/src/Nethermind.

Expected outcome

A source-built Nethermind mainnet client is started, with documented test commands available for validation.

Guide limitations

  • This recipe does not cover system requirements, consensus-client configuration or production operations.
  • The documented source-build prerequisite is .NET SDK 10 or later.
