Optimism is Ethereum, scaled.

Table of Contents

What is Optimism?

Optimism is a project dedicated to scaling Ethereum's technology and expanding its ability to coordinate people from across the world to build effective decentralized economies and governance systems. The Optimism Collective builds open-source software that powers scalable blockchains and aims to address key governance and economic challenges in the wider Ethereum ecosystem. Optimism operates on the principle of impact=profit, the idea that individuals who positively impact the Collective should be proportionally rewarded with profit. Change the incentives and you change the world.

In this repository you'll find numerous core components of the OP Stack, the decentralized software stack maintained by the Optimism Collective that powers Optimism and forms the backbone of blockchains like OP Mainnet and Base. The OP Stack is designed to be aggressively open-source — you are welcome to explore, modify, and extend this code.



Detailed specifications for the OP Stack can be found within the OP Stack Specs repository.


General discussion happens most frequently on the Optimism discord. Governance discussion can also be found on the Optimism Governance Forum.


The OP Stack is a collaborative project. By collaborating on free, open software and shared standards, the Optimism Collective aims to prevent siloed software development and rapidly accelerate the development of the Ethereum ecosystem. Come contribute, build the future, and redefine power, together. contains a detailed explanation of the contributing process for this repository. Make sure to use the Developer Quick Start to properly set up your development environment.

Good First Issues are a great place to look for tasks to tackle if you're not sure where to start.

Security Policy and Vulnerability Reporting

Development and Release Process


Please read this section carefully if you're planning to fork or make frequent PRs into this repository.

Production Releases

Production releases are always tags, versioned as <component-name>/v<semver>. For example, an op-node release might be versioned as op-node/v1.1.2, and smart contract releases might be versioned as op-contracts/v1.0.0. Release candidates are versioned in the format op-node/v1.1.2-rc.1. We always start with rc.1 rather than rc.

For contract releases, refer to the GitHub release notes for a given release which will list the specific contracts being released. Not all contracts are considered production ready within a release and many are under active development.

Tags of the form v<semver>, such as v1.1.4, indicate releases of all Go code only, and DO NOT include smart contracts. This naming scheme is required by Golang. In the above list, this means these v<semver releases contain all op-* components and exclude all contracts-* components.

op-geth embeds upstream geth’s version inside it’s own version as follows: vMAJOR.GETH_MAJOR GETH_MINOR GETH_PATCH.PATCH. Basically, geth’s version is our minor version. For example if geth is at v1.12.0, the corresponding op-geth version would be v1.101200.0. Note that we pad out to three characters for the geth minor version and two characters for the geth patch version. Since we cannot left-pad with zeroes, the geth major version is not padded.

See the Node Software Releases page of the documentation for more information about releases for the latest node components.

The full set of components that have releases are:

  • chain-mon
  • ci-builder
  • ci-builder
  • op-batcher
  • op-contracts
  • op-challenger
  • op-heartbeat
  • op-node
  • op-proposer
  • op-ufm
  • proxyd

All other components and packages should be considered development components only and do not have releases.

Development branch

The primary development branch is develop. develop contains the most up-to-date software that remains backwards compatible with the latest experimental network deployments. If you're making a backwards compatible change, please direct your pull request towards develop.

Changes to contracts within packages/contracts-bedrock/src are usually NOT considered backwards compatible. Some exceptions to this rule exist for cases in which we absolutely must deploy some new contract after a tag has already been fully deployed. If you're changing or adding a contract and you're unsure about which branch to make a PR into, default to using a feature branch. Feature branches are typically used when there are conflicts between 2 projects touching the same code, to avoid conflicts from merging both into develop.
