About ESP

We provide grants and other support for free and open-source projects that strengthen Ethereum's foundations, with a particular focus on builder tools, infrastructure, research and public goods.

Supporting Builders

ESP funding is generally directed toward supporting builders rather than directly impacting end users. We don't often fund dapps or front-end platforms, although this is not a hard rule and there are exceptions - for example, where an application serves as a research or educational tool, or a reference implementation of a new standard.

Our grantees come from all over the world and represent many different backgrounds, disciplines and levels of experience. We have supported individuals and teams of all kinds - companies, DAOs, nonprofits, institutions, academics, developers, educators, community organizers and more.

Our blog also features monthly roundups which showcase grantees' progress after their grants are awarded and go into more detail about their background and work.
