Ethereum Foundation Ecosystem Support Program (ESP) is a grant from the Ethereum Foundation that funds open-source projects, research, and tools that strengthen the Ethereum ecosystem. The program prioritizes work that improves Ethereum's infrastructure, expands tools available to developers, advances cryptographic research, and creates positive-sum outcomes for the broader community.

Supported work must be free, open-source, non-commercial, and designed to benefit the ecosystem. Eligible applicants include individual researchers, open-source developers, and small businesses. Grants typically range from $5,000 to $50,000 with no fixed application deadline.

Applicants Overview | Ethereum Foundation ESP PhD Fellowship Program is now open! Whether you're working on a specific project, or you're still exploring possibilities, you can connect with our team for guidance. ESP provides financial and/or non-financial support to eligible projects working to improve Ethereum.

We focus on work that strengthens Ethereum's foundations and enables future builders. The work we support is free, open-source, non-commercial, and designed to create positive sum outcomes for the community.

Our support is generally directed toward enabling builders rather than end-users: strengthening Ethereum's infrastructure, expanding the range of tools available to those building on Ethereum, gaining a deeper understanding of cryptographic primitives, growing the builder ecosystem through education and community development, etc. Browse the available Wishlist or RFP items and find one that matches your interests and expertise.

Each item includes a detailed description and, when applicable, relevant resources. Submit your application detailing how you plan to address the Wishlist or RFP item. Describe how your background and approach align with the project requirements by providing clear information on your methodology, timeline, and deliverables.

Once submitted, you will receive a confirmation email. The Grant Management (GM) team reviews applications in collaboration with the EF team responsible for the corresponding Wishlist or RFP item. The evaluation process may include: an interview to discuss your proposal in detail, project rescoping, or budget negotiations.

You will be notified of funding decisions via email. If your project is selected, we will work closely with you to establish a clear grant structure with milestone-based payments. All grant recipients also complete an onboarding process, involving KYC verification and signing a legal grant agreement.

Begin work on your project with ongoing support from the GM team. You will be paired with a Grant Evaluator for regular check-ins, milestone reviews, and support as you progress. Once the scope of work is completed, you will share the results publicly in a report or post.

Applications are evaluated based on several key factors, such as: Technical approach : Soundness, feasibility, and clarity of your proposed methodology and implementation plan Ecosystem impact : Potential benefit to the Ethereum community and alignment with ecosystem priorities Open source : All outputs must be open-source or otherwise freely available; for-profit companies are welcome to apply, but the specific grant-funded work must be open-source and accessible to the community Budget : Cost-effectiveness and appropriate allocation of resources; since we are offering non-dilutive capital, we generally anticipate some flexibility below standard market rates Experience : Relevant background, skills, and prior work that demonstrate capability Alignment : Understanding of Ethereum's values and ecosystem needs, and how your work contributes to them What's the difference between Wishlist and RFP items?

Wishlist items identify key gaps and opportunities within the ecosystem. Instead of prescribing specific approaches, it invites builders to propose ideas and initiatives that address these priorities. On the other hand, RFP items define focused problems and invites applicants to propose solutions.

They are more prescriptive and time-bound than Wishlist items, focusing on a clear deliverable or outcome to be achieved. Can I apply for multiple Wishlist or RFP items simultaneously? You can apply for multiple items, but we recommend focusing on those that best match your expertise.

If applying for multiple items, please submit separate applications for each. How long does the evaluation process take? After submitting your application, you will receive a confirmation email.

Most applications are reviewed within 3-6 weeks, though the exact timeline may vary depending on the complexity of the Wishlist or RFP item and the details of the application. How often are new Wishlist or RFP items added? Items are added based on the evolving needs and strategic priorities of the Ethereum ecosystem.

To stay up to date, follow ESP on X (Twitter) , Farcaster , Lens , or Bluesky , or check back periodically for updates on new opportunities. What is the typical funding range for a grant awarded through the Wishlist or RFP? Grant funding is determined based on the scope and complexity of the proposal, unless otherwise specified in the posted Wishlist or RFP item.

Where applicable, RFPs may include budget guidance estimates. The GM team will work with applicants to determine final grant amounts. Looking for different support?
