Reth
A modular, Rust-based Ethereum execution client by Paradigm — clean architecture, modern codebase, gaining mainnet adoption since its 2024 production release.
Reth ships an Ethereum execution client written in Rust with a modular design that exposes the core data structures (StateDB, mempool, RPC) as reusable libraries other projects can embed. The Paradigm team launched it as production-ready in 2024.
The client targets both standalone Ethereum operation and "node-as-a-library" use cases — many rollup stacks (Optimism, Base via op-reth) ship Reth-derived execution layers. Its emphasis on modularity and Rust safety makes it a strong client-diversity contribution.
