Ethereum Core Development Funding At Risk As Client Incentive Program Expires in April 2026

According to Trent Van Epps, a former Ethereum Foundation contributor, the Ethereum Foundation's major Client Incentive Program expired in April 2026 without a successor, creating a potential funding crisis for core protocol development. Van Epps warned the ecosystem could face significant funding shortfalls within three to nine months as the foundation executes a treasury plan announced in June 2025, gradually reducing its annual spending from 15% toward a 5% endowment baseline by 2030.

Van Epps estimates sustaining Ethereum's network of over ten client teams, researchers, and coordination groups costs approximately $30 million annually. He emphasized that no replacement funding mechanism has been announced to address the gap left by the program's expiration, warning that delays in establishing new funding sources could lead to contributor attrition and slower progress on critical challenges including quantum computing resilience and scaling solutions.
