A former Ethereum Foundation (EF) member has sounded the alarm regarding a potential "slow-burning funding crisis" that could impact the core development ecosystem of Ethereum in the coming months. Trent Van Epps, who was actively involved with the Ethereum Foundation from May 2021 to April 2026, articulated his concerns in a detailed blog post, highlighting a confluence of strategic shifts and program expirations that could create a significant funding gap for the teams essential to maintaining and advancing the Ethereum network.
Van Epps’ warning arrives at a critical juncture for Ethereum. The blockchain is on the cusp of significant technological advancements, including its upcoming Glamsterdam upgrade, while simultaneously navigating internal organizational restructuring, a deliberate reduction in spending by its primary funding body, and ongoing discussions about the Foundation’s long-term role in a progressively decentralized ecosystem. This period of transition, coupled with the potential for a funding shortfall, raises questions about the sustainability of Ethereum’s robust development pipeline and its ability to address future challenges.
Dual Pressures on Ethereum’s Development Funding
According to Van Epps, two primary developments are converging to place considerable pressure on the financial resources available for Ethereum’s core development.
Firstly, the Ethereum Foundation has embarked on a strategic, long-term treasury management plan. Announced in June 2025, this initiative aims to systematically reduce the Foundation’s annual spending rate. The target is a significant decrease from the current approximate 15% to a more conservative 5% by the year 2030. The explicit objective of this strategy is to ensure the longevity and preservation of the Foundation’s remaining assets, thereby guaranteeing its capacity to support the ecosystem over an extended period. This approach, while prudent for long-term financial health, inevitably means a reduction in the immediate capital available for project funding.
Secondly, a crucial four-year program designed to bolster Ethereum client teams has concluded. The Client Incentive Program (CIP), which provided vital financial support to these teams through staking rewards, officially ended in April 2026. To date, no direct successor program has been announced to fill this void. The CIP played a pivotal role in fostering the development and maintenance of the various client software implementations that underpin the Ethereum network, ensuring its resilience and diversity. Its expiration, without an immediate replacement, leaves a substantial funding uncertainty for these critical contributors.
Van Epps posits that the simultaneous implementation of these two developments—reduced outgoing funds from the Foundation and the cessation of a dedicated client funding program—could create a substantial funding deficit for the teams responsible for the very backbone of the Ethereum network.
The Looming Funding Gap and Its Implications
"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," Van Epps stated in his blog post. This candid assessment underscores the urgency of the situation.
He further estimated that the annual financial requirement to sustain Ethereum’s extensive network of over 10 core client teams, along with essential research and coordination activities, hovers around $30 million. This figure represents a significant but arguably necessary investment to maintain the network’s cutting-edge status and operational integrity.
The potential consequences of a sustained funding shortfall are far-reaching. Van Epps cautioned that Ethereum risks a substantial brain drain, potentially losing developers who have accumulated years of specialized knowledge and invaluable context within the ecosystem. This loss of institutional memory and expertise could have cascading effects on the pace and quality of future development.
"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 elaborated. This statement highlights the tangible threats to Ethereum’s future, from its competitive edge against emerging technologies to its fundamental promise of stability and performance.
The Philosophy of "Subtraction" and its Challenges
Central to this discussion is the Ethereum Foundation’s guiding organizational philosophy, known as "Subtraction." First introduced in 2019 and re-affirmed in the Foundation’s March 2026 mandate, this strategy is rooted in the objective of gradually diminishing the Foundation’s direct influence and actively encouraging greater decentralization across the entire Ethereum ecosystem. The overarching goal, as articulated by the Foundation, is to foster an environment where Ethereum becomes sufficiently mature and self-sufficient to "outgrow and outlast" the organization itself. This vision aligns with the core tenets of decentralization that underpin blockchain technology.
However, Van Epps argues that despite these stated intentions and the philosophical shift towards "Subtraction," the Ethereum Foundation continues to wield considerable influence. This influence, he notes, stems from its established brand recognition, its substantial treasury, its ownership of valuable ecosystem assets, and its close, enduring association with Ethereum co-founder Vitalik Buterin. These factors, he suggests, mean that the Foundation’s role, even as it seeks to recede, remains central.
A key point of contention raised by Van Epps is the ecosystem’s current inability to fully absorb the Foundation’s responsibilities. He observed that the broader Ethereum ecosystem has yet to establish robust alternative institutions that are fully equipped to take over many of the functions currently performed by the Foundation. This creates a dependency that the "Subtraction" strategy, in its current implementation, may not fully address.
"Legitimacy is downstream of repeated competency, which is itself downstream of resources," Van Epps emphasized, underscoring his belief that adequate financial support remains an indispensable prerequisite for sustaining and advancing Ethereum’s development capabilities. This highlights a fundamental tension between the ideal of complete decentralization and the practical necessities of funding complex, ongoing development efforts.
A Wave of Departures and the Need for New Models
The concerns about funding are occurring against a backdrop of notable departures from the Ethereum Foundation. Over the past year, several prominent figures and long-term contributors have exited the organization. These include distinguished developer Péter Szilágyi, veteran contributor Josh Stark, Beacon Chain architect Karl Bickhusen, and researcher Julian Ma. These departures, while not explicitly linked to funding issues by the individuals themselves in all cases, contribute to a perception of organizational flux and potentially signal a broader shift in contributor engagement.
Trent Van Epps himself concluded his tenure at the Foundation in April, although he continues to contribute to the ecosystem through his involvement with the Protocol Guild, an organization focused on funding core Ethereum developers.
Van Epps’ analysis extends beyond simply identifying a funding gap. He contends that resolving Ethereum’s development sustainability challenges will necessitate more than just short-term financial injections. Instead, he advocates for the establishment of new, resilient institutions within the ecosystem. Furthermore, he stresses the critical need to create "scalable, accountable, neutral funding mechanisms" that are capable of providing sustained support for development initiatives over the next decade and beyond. This points towards a need for more formalized, community-driven funding models that can operate independently of the Foundation’s direct involvement.
The Road Ahead: Glamsterdam and Funding Uncertainty
The current debate surrounding funding takes place as significant progress continues on Ethereum’s upcoming Glamsterdam upgrade. This major network enhancement, which promises to introduce a suite of crucial improvements, relies heavily on the very development teams that are now facing potential funding uncertainties. The success of Glamsterdam, and indeed future upgrades, will likely be contingent on the ability of the ecosystem to secure consistent and adequate financial backing for its core contributors.
With no immediate successor to the Client Incentive Program in place, the Ethereum community faces a pivotal moment. Decisions made in the coming months will determine how the network’s future development will be financed, while simultaneously striving to uphold and enhance its foundational principles of decentralization and open access. The challenge lies in balancing the imperative for continued innovation with the commitment to a decentralized ethos, ensuring that Ethereum remains a robust and evolving platform for years to come. The outcome of this funding discussion will be a significant indicator of the ecosystem’s maturity and its capacity for self-governance in the realm of core development funding.
