OP Labs

OP Labs develops the technology behind Optimism, a blockchain infrastructure platform that lets developers and enterprises build applications onchain through the open-source OP Stack. The OP Stack is a modular and customisable framework for scaling Ethereum, designed to provide Ethereum-grade security, fast transactions and production-ready networks that anyone can launch. According to the company, it powers more than 65% of all Layer 2 transactions.

The Optimism protocol is an extension to Ethereum that delivers orders-of-magnitude improvements in performance and scalability while committing to public goods. Its technical work spans blockchain infrastructure, Ethereum Layer 2 scaling, modular blockchain architecture, open-source protocol development and smart contract platforms. The OP Stack is open source, and contributions from external developers are part of how the codebase is built and maintained.

OP Labs is structured as a Public Benefit Corporation and states a mission to bring decentralised technology to a mass audience, scaling both Ethereum's technology and its values. The company has raised over $175M in funding, with investors including a16z and Paradigm. Engineering work is oriented toward protocol research, distributed systems and developer tooling in the Ethereum ecosystem.
