## What it is
Reth is a production-ready, modular Ethereum execution layer client written in Rust, usable both as a full node binary and as a set of composable library crates for building custom EVM-compatible nodes. It supports the Engine API with all major consensus clients and offers high performance, extensibility via ExExs, and permissive Apache/MIT licensing.

## Use cases
- run an Ethereum full node for staking or RPC services
- sync and index EVM chain data for MEV or analytics
- build a custom EVM-compatible blockchain node from modular crates
- extend a node with custom offchain logic using ExExs
- serve JSON-RPC and trace APIs for dapps and infrastructure
- run a node for L2s like Base, Gnosis Chain, or BSC

## When to choose
- you need a fast, production-grade Ethereum execution client
- you want to build a custom node reusing battle-tested components
- you need permissively licensed infrastructure for commercial use
- you want client diversity for Ethereum staking or RPC operations

## When to avoid
- you need a consensus layer client rather than an execution layer
- you want a non-EVM blockchain client
- you need a lightweight wallet or dapp frontend rather than node infrastructure

## Facets
- artifact type: application
- maturity: stable
- function: p2p, rpc, database, sdk, cli, developer-tools
