Launch a private Ethereum Testnet with all clients and MEV infra
We've been working with the Ethereum Foundation & Flashbots to build tooling and infrastructure for developers to test various workflows for Ethereum. As part of that work, anyone can now spin up a local Ethereum dev net with the entire Flashbots mev-boost infra (relayer, builder, boost) using the ethereum-package. This package supports all EL and CL client types, works on Kubernetes for scale testing, and comes with a few bells and whistles like metrics, mock-builders, and beacon chain explorers. This is the de-facto tool for teams modifying and testing the consensus layer. Here's a full…
In plain words
The ethereum-package allows developers to quickly launch a private Ethereum testnet locally with complete MEV-boost infrastructure, including relayers, builders, and boost components. It supports all execution layer and consensus layer client types, scales on Kubernetes, and includes metrics, mock-builders, and beacon chain explorers. Designed for teams testing and modifying Ethereum consensus layer functionality, it provides a comprehensive development environment for blockchain testing workflows.
