Ethereum’s core development ecosystem is facing a potential funding crisis in the coming months, a scenario detailed by former Ethereum Foundation (EF) member Trent Van Epps. Van Epps, who served at the Foundation from May 2021 to April 2026, articulated his concerns in a detailed blog post, warning of a "slow-burning funding crisis" that could significantly impede the network’s long-term development trajectory. This assessment comes at a critical juncture for Ethereum, a period marked by preparations for crucial network upgrades, ongoing organizational adjustments, strategic spending reductions, and continued discussions regarding the Ethereum Foundation’s evolving role.
Van Epps identified two primary catalysts for this potential funding shortfall. The first is the Ethereum Foundation’s deliberate long-term treasury strategy, which aims to progressively decrease its annual spending rate from approximately 15% to a more sustainable 5% by the year 2030. This initiative, first announced in June 2025, is designed to safeguard the Foundation’s remaining assets and ensure its enduring viability. The second critical factor is the conclusion of the Client Incentive Program (CIP), a four-year initiative that provided essential financial support to Ethereum client teams through staking rewards. The program officially ended in April 2026, with no immediate successor announced, creating an immediate void in funding for teams vital to maintaining Ethereum’s infrastructure.
The Looming Funding Gap
According to Van Epps’ analysis, these concurrent developments could create a substantial funding deficit for the teams responsible for the day-to-day maintenance and evolution of Ethereum’s core infrastructure. He stated, "From recent conversations across all core development, there is a risk we will enter a slow-burning funding crisis within the next 3-9 months." This projected crisis underscores the critical need for consistent and reliable financial backing to sustain the complex network of over 10 client teams, as well as the crucial research and coordination activities that underpin Ethereum’s progress. Van Epps estimates that the annual requirement to maintain this ecosystem, including research and coordination efforts, hovers around $30 million.
The potential consequences of inadequate funding are severe, according to Van Epps. He warned that without sustained financial support, Ethereum risks losing invaluable developers who have cultivated years of specialized knowledge and deep contextual understanding of the network’s intricate workings. "Without continuous funding, we lose people with critical context built up over years, fall behind on looming challenges like quantum computing or scaling, and ultimately risk mainnet’s reputation for reliability," he emphasized. This loss of expertise could jeopardize Ethereum’s ability to address future technological challenges, such as the existential threat posed by quantum computing, and its ongoing efforts to enhance scalability, ultimately impacting the network’s fundamental reliability.
The Philosophy of "Subtraction" and Its Implications
At the heart of this discussion lies the Ethereum Foundation’s guiding organizational philosophy, often referred to as "Subtraction." This strategy, first articulated in 2019 and reaffirmed in the Foundation’s March 2026 mandate, advocates for a gradual reduction of the Foundation’s direct influence and a concerted effort to foster greater decentralization across the entire Ethereum ecosystem. The Foundation has publicly stated its overarching objective: to cultivate an Ethereum network mature enough to "outgrow and outlast" the organization itself. This vision points towards a future where Ethereum can operate autonomously, driven by a diverse and self-sufficient community.
However, Van Epps argues that despite these well-intentioned goals, the Ethereum Foundation continues to wield significant influence through its established brand, substantial treasury, valuable ecosystem assets, and its close association with Ethereum co-founder Vitalik Buterin. He highlights a critical gap in the ecosystem’s current structure: the absence of alternative institutions capable of fully assuming many of the responsibilities historically shouldered by the Foundation. This suggests that the transition towards a more decentralized model may be encountering friction due to a lack of robust, established decentralized entities ready to take the reins.
Van Epps articulated this challenge by stating, "Legitimacy is downstream of repeated competency, which is itself downstream of resources." This assertion emphasizes that financial resources are not merely a logistical requirement but a fundamental prerequisite for building and maintaining the technical competence and credibility necessary for sustained development. Without adequate financial backing, the capacity to consistently deliver high-quality development and innovation is inherently compromised, potentially undermining the ecosystem’s overall legitimacy and progress.
A Wave of Departures and the Need for New Frameworks
The concerns regarding funding emerge against a backdrop of notable departures from the Ethereum Foundation. Over the past year, several prominent figures have transitioned away from the organization, including developer Péter Szilágyi, longtime contributor Josh Stark, Beacon Chain architect Karl Bickhusen, and researcher Julian Ma. Van Epps himself departed the Foundation in April 2026, though he continues to contribute to the ecosystem through his involvement with Protocol Guild, an organization dedicated to supporting Ethereum core developers. These departures, while potentially a natural part of organizational evolution, raise questions about the long-term sustainability of institutional knowledge within the Foundation and the broader core development teams.
Van Epps posits that addressing Ethereum’s current and future challenges requires a more profound solution than temporary financial injections. He advocates for the establishment of new, robust institutions within the ecosystem. These entities would be tasked with creating "scalable, accountable, neutral funding mechanisms" that can provide consistent and reliable support for development over the next decade and beyond. Such mechanisms would need to be designed to operate independently of any single organization, ensuring long-term stability and preventing future funding crises.
The Road Ahead: Glamsterdam and Decentralized Funding Models
This ongoing debate unfolds as development continues on Ethereum’s upcoming Glamsterdam upgrade. This significant update, poised to introduce substantial improvements to the network, relies heavily on the expertise of the very development teams currently facing funding uncertainties. The success of Glamsterdam, and indeed future upgrades, is intrinsically linked to the financial stability of these core contributors.
The expiration of the Client Incentive Program without a clear successor presents the Ethereum community with a critical decision point. The community must actively explore and implement new funding models that align with its core principles of decentralization while ensuring the continued robust development and security of the network. This might involve exploring novel decentralized autonomous organizations (DAOs) focused on grants and funding, innovative tokenomic models designed to incentivize core development, or a combination of approaches. The path forward will require careful consideration of how to balance the need for centralized coordination in funding with the ultimate goal of a truly decentralized and self-sustaining ecosystem. The future of Ethereum’s evolution, moving beyond its current foundational structures, hinges on its ability to forge these new, resilient funding pathways.
