One of the most credible voices to ever work inside the Ethereum Foundation just published the most direct warning the organization has received from one of its own. Trent van Epps, who spent five years at the EF coordinating core development and protocol funding before leaving in April 2026, wrote that Ethereum’s core infrastructure faces a slow-burning funding crisis that could fully materialize within 3 to 9 months — and that the structural causes go far deeper than a temporary budget gap.

The warning lands at a moment when ETH itself is already under scrutiny. Bankless co-founder David Hoffman recently sold his entire ETH position, arguing that network growth and asset appreciation have decoupled. Van Epps’ essay adds an institutional dimension to that skepticism — suggesting that even Ethereum’s technical foundation, the part of the ecosystem least exposed to speculative sentiment, is running out of runway.

What “Subtraction” Actually Means — and Why It’s Backfiring

Van Epps centers his analysis on a philosophy the Ethereum Foundation has openly embraced for seven years, internally called “Subtraction.” The idea, first articulated in 2019 and restated in the EF’s March 2026 Mandate, is that the Foundation should deliberately shrink its relative influence over time — pushing value creation out into the broader ecosystem rather than accumulating it internally.

As a governance principle, Subtraction has succeeded in one specific way: it has convinced the community that the EF does not want to be Ethereum’s permanent center of gravity. But Van Epps argues it has failed to specify what happens to the functions the Foundation currently performs once it steps back.

Legitimacy, he writes, tends to pool according to power-law dynamics rather than disperse evenly — and right now there is still only one institution with the brand trust, Vitalik Buterin’s direct affiliation, ownership of ethereum.org and the @ethereum handle, and historical employment of roughly a quarter of active core protocol contributors. Subtraction has reduced the Foundation’s appetite to use that position. It has not yet produced a replacement for it.

The Treasury Is the Real Constraint

The philosophical debate matters less than the financial one underneath it. Van Epps is explicit that legitimacy is downstream of competency, and competency is downstream of resources — and the EF’s resources are shrinking on a defined schedule. The Foundation has spent down a significant portion of its ETH treasury over the past decade bootstrapping the ecosystem, and in June 2025 it adopted a formal glide path to cut annual spending from roughly 15% of treasury value down to a 5% endowment-style baseline by 2030.

That kind of disciplined drawdown is standard practice for any institution trying to ensure long-term solvency. But it collides directly with a second, less foreseeable event: the Client Incentive Program — a four-year initiative that funded the teams maintaining Ethereum’s client software through staking rewards — expired in April 2026 with no announced successor. Two funding mechanisms that ecosystem developers had built multi-year plans around have now both contracted or disappeared in the same calendar window.

Van Epps puts a number on what’s actually required to keep the lights on: approximately $30 million annually, spread across client teams, researchers, and coordination staff working across more than ten different client implementations. Against Ethereum’s market capitalization, or against the amount of value secured on the network, that figure is trivial. Against an EF treasury that is deliberately winding down its annual disbursements, it is no longer guaranteed.

Why a Funding Gap Becomes an Institutional Capacity Problem

The most important argument in Van Epps’ piece isn’t about dollars — it’s about what happens to people and knowledge when the dollars disappear. Ethereum’s ability to ship complex, security-critical protocol upgrades across a dozen independently maintained clients is not a static asset. It is built from specific engineers who have accumulated years of context about how the protocol actually works, where its fragile edges are, and how previous upgrades were coordinated.

That expertise doesn’t sit in a treasury report; it sits in people who can leave the ecosystem the moment funding becomes unreliable.

Van Epps’ core warning is about timing asymmetry: the damage from underfunding shows up 12 to 18 months after the funding actually disappears, by which point the contributors who left have already moved on and the institutional memory they carried has already eroded. He argues the industry is structurally bad at pricing this kind of risk — it looks survivable in the moment and becomes expensive only in hindsight, with looming technical challenges like quantum resistance and further scaling work sitting squarely in the crosshairs of whatever capacity gets lost.

A Foundation That Was Never Meant to Be Permanent

Van Epps frames the funding crisis as inseparable from a larger succession question, quoting Vitalik Buterin’s own recent acknowledgment that the EF “was not designed to be an eternal steward” — its original mandate, tied to the token sale documents, was completed back in 2022. If that’s true, then the Foundation’s declining capacity isn’t a malfunction; it’s the natural endpoint of a structure designed to phase itself out. The unresolved question Van Epps raises is who, or what, actually inherits that stewardship role, and whether any replacement mechanism currently exists with comparable legitimacy, neutrality, and resourcing.

He proposes three design principles for whatever comes next: explicit, accountable stewardship over Ethereum’s software, network, and asset as three distinct but interdependent resources; funding mechanisms that are neutral and scalable rather than dependent on a single treasury; and a renewed willingness to prioritize broad adoption rather than treating it as secondary to internal governance principles. None of these exist yet in a form the ecosystem has coalesced around.

A Skepticism That Extends Beyond One Essay

Van Epps is not a lone voice raising these concerns. His essay arrives alongside a broader wave of public skepticism about Ethereum’s direction — from prominent community figures questioning whether ETH the asset can capture the value that Ethereum the network continues to generate, to ongoing debate about whether the Foundation’s governance philosophy has kept pace with the scale of what it’s responsible for. The fact that this particular warning comes from someone who spent five years inside the institution, coordinating the very funding mechanisms now under strain, gives it a different weight than commentary from outside observers.

Van Epps’ own departure in April 2026 is itself part of a broader pattern. In recent months, the Ethereum Foundation has seen a notable wave of departures, with several experienced staff members and researchers leaving the organization — raising separate but related concerns about institutional knowledge loss at precisely the moment the Foundation is also reducing its financial capacity. The combination of fewer resources and fewer veteran staff compounds the risk Van Epps describes: it’s not just that funding is contracting, but that the people who best understand how to allocate scarce funding effectively are leaving alongside it.

Ethereum’s protocol layer has weathered funding uncertainty before. What Van Epps is describing is not a single crisis but a compounding one — a treasury drawdown, an expired incentive program, and an unresolved succession question landing in the same narrow window, with consequences that may not be fully visible until well after the window has closed.
