Privacy + Scaling Explorations
Building free resources for people expanding the world of programmable cryptography.
What we do

PSE is a multidisciplinary team creating open source privacy and scaling tools for the next generation's internet.


We believe privacy is a social good that should be accessible to everyone. That's why we're creating open source tools that help people choose what, how, when, and where they share.


Our infrastructure helps communities grow by making Ethereum more efficient and accessible. From account abstraction and reducing transaction costs, to rollups and zkEVM, we are building towards an interoperable future.


We are mapping the emerging zero knowledge ecosystem through collective experimentation. We collaborate, share what we learn, and welcome contributions from around the world.
