Welcome to the Optimism Docs
Welcome to the Optimism Docs, the unified home of the Optimism Collective's technical documentation. The Optimism Collective is a band of people, projects, and companies working together to build a better economy for everyone.
Here you'll find everything you need to know about the Optimism tech stack, including OP Mainnet, the OP Stack, the Optimism Superchain, and more. Information about the Optimism Collective's governance, community, and mission can be found on the Optimism Community Hub (opens in a new tab).
The Optimism Docs are designed to help you build with Optimism. Whether you're a developer building a dapp on OP Mainnet, a node operator running an OP Mainnet node, or a chain operator launching your own OP Stack chain, you'll find everything you need to get started right here.
OP Mainnet is an EVM equivalent (opens in a new tab) Layer 2 blockchain connected to Ethereum. The OP Stack is the standardized, shared, and open-source development stack that makes it easy to spin up your own production-ready Layer 2 blockchain just like OP Mainnet. The Superchain is a network of OP Stack chains that share a bridging protocol, governance system, and more. We've got you covered with these detailed guides to help you learn all about Optimism's tech stack.
