The Optimism Collective is redistributing power to humanity through a low-cost, lightning-fast Ethereum-equivalent L2 blockchain.

The OP Stack is the standardized, shared, and open-source development stack powering Optimism Mainnet and the Superchain. It maximizes interoperability and composability between different chains using the OP Stack.

Optimism’s RetroPGF is changing the way impactful software is rewarded. The Optimism Collective funds projects that promote the growth of the Optimism ecosystem. You build projects with impact, you get paid.
