## What it is
OpenEthereum is a fast, light, and robust Ethereum client written in Rust, providing full node infrastructure with JSON-RPC HTTP and WebSocket APIs. The project is now deprecated and no longer maintained.

## Use cases
- run an ethereum full node
- sync ethereum mainnet quickly with warp sync
- serve json-rpc api for a dapp backend
- run a node for mining or exchange infrastructure
- self-host ethereum blockchain infrastructure

## When to choose
- you need a historical Rust Ethereum client for research or archival purposes
- you want a lightweight client with warp sync on an older network snapshot

## When to avoid
- you need an actively maintained Ethereum client for mainnet today
- you need support for recent Ethereum hard forks like the Merge
- you are starting a new project - use Geth, Nethermind, or Reth instead

## Facets
- artifact type: application
- maturity: abandoned
- function: http-server, websocket, cli, rpc
- domain: blockchain, developer-tools
- platform: windows, rust, cli
- tags: ethereum-client, blockchain-node, json-rpc, deprecated, warp-sync, cryptocurrency, linux, macos
