About the program

The Ecosystem Support Program funds work that benefits Ethereum as a whole rather than a single product. Most grants go to open-source tools, research and community resources.

Small grants cover early experiments and focused deliverables. Larger project grants support multi-month efforts with clear milestones.

What they fund

  • Client and protocol tooling
  • Zero-knowledge and cryptography research
  • Developer experience and documentation
  • Community education and events

Who can apply

  • Individuals, teams and research institutions
  • Work must be open source or openly published
  • Projects should benefit Ethereum broadly, not one company
  • No token launch or fundraising required

How applying works

  1. Read the priorities

    Check the program's current focus areas to see where your project fits.

  2. Submit an application

    Describe the problem, your plan, the team and a budget split into milestones.

  3. Talk with a reviewer

    Shortlisted applicants agree on scope and deliverables with the program team.

  4. Deliver and report

    Funds are released as each milestone is completed and reported.
