We pledge to uphold the values of Ethereum by producing infrastructure that promotes the growth and sustainability of public goods.

our philosophy
The Optimism Foundation is a nonprofit organization dedicated to growing the Optimism Collective.

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.
