ethereumjs-monorepo

The ethereumjs-monorepo is an open-source, TypeScript-based implementation of the Ethereum L1 protocol stack and EVM, providing modular libraries for core blockchain functionality like execution, state management, and networking. It is designed for developers building Ethereum clients, tools, or research prototypes who need a flexible, well-documented alternative to the Go or Rust implementations. Its interest lies in enabling rapid experimentation and cross-platform compatibility within the Ethereum ecosystem, all while maintaining high code quality and adherence to evolving protocol specifications.
