About OP Labs PBC

OP Labs PBC develops open-source software that powers the Optimism Collective. The company builds the OP Stack, a modular, MIT-licensed codebase enabling organizations to launch their own Ethereum Layer-2 blockchains. It focuses on scalability, security, and decentralization, providing core protocol upgrades, developer tools, and infrastructure managed by the Optimism Foundation. OP Labs’ engineering team coordinates with the broader Optimism ecosystem to deliver fault proofs, sequencer decentralization, and governance mechanisms supporting public-goods funding and retroactive incentives.
