What to know
Reth is Paradigm's production-ready Ethereum execution-layer client and modular SDK, written in Rust and stable since its 1.0 release in June 2024. Within the Tempo ecosystem it is the foundation Tempo's EVM-compatible execution layer is built on, handling transaction execution and state management.
Best for
- +EVM-compatible smart-contract execution on Tempo
- +Building on Tempo's execution layer via the Reth SDK
- +Teams wanting a production-ready Rust execution client
Watch out
- Reth is a general-purpose execution client/SDK, not a Tempo-specific token standard or payment feature
- Tempo-specific behavior comes from surrounding protocol components, not from generic upstream Reth alone
