Introduction

We continue to build open source public goods to help the Ethereum and Optimism community get better and better.

Our Works​

We have currently developed two important components of core OP Stack protocol:

  • Hildr is an optimism rollup node written in Java.

  • Op-besu is an optimism execution client written in Java, a fork of Besu.

In addition, we have also developed OP Stack related tools.

  • Blob-archiver-rs is a service to archive and allow querying of all historical blobs from the beacon chain written in Rust.

  • Superproof is a fault proof explorer to visualize dispute game progress and statistics.

Meanwhile, we also contributed in other community projects.

  • Shisui is an ethereum portal network client written in Go.

  • Mev-share-java is a Java client library for Flashbots MEV-share Matchmaker.
