our philosophy
Optimism is a Public Benefit Corporation, a for profit corporation that is obligated to balance financial interests of our stockholders with the best interests of our community, and society.

Not only are we writing software that scales Ethereum technology, we are also scaling Ethereum values by creating the rails for highly impactful projects that don’t have a business model to succeed. Read more about how we’re doing that here.

Until the project is fully decentralized, we will be donating all profits from running a centralized sequencer towards scaling and sustaining public goods. Stay tuned for the announcement of our very first donation round.
