Ethereum Core Development Faces Funding Gap as Four-Year Client Program Expires
A former Ethereum Foundation coordinator says the network could run short of money to sustain its core developer teams within months. The warning arrives as ETH trades roughly 64% below its August 2025 peak and a major protocol upgrade has already slipped.
Trent Van Epps, who served as a core development coordinator at the Ethereum Foundation before leaving in April 2026, posted a public warning on June 18 that Ethereum could face a "slow-burning funding crisis" for its core protocol work within three to nine months. The projected window runs from approximately September 2026 through March 2027. The immediate trigger is the expiry of the Client Incentive Program (CIP), a four-year funding scheme the Ethereum Foundation launched in December 2021 that formally ended in April 2026.
The CIP worked by allocating validator stakes directly to client teams, allowing them to earn staking rewards over time as a form of ongoing compensation. To remain eligible, teams were required to maintain a 95% minimum attestation rate and a 95% block proposal rate. Nine teams received allocations under the program: Erigon, Go-Ethereum (Geth), Hyperledger Besu, Lighthouse, Lodestar, Nethermind, Nimbus, Prysm, and Teku. Each received 144 validators worth 4,608 ETH, except Lodestar, which received half that amount. In total, the program distributed approximately 42,000 ETH across the four-year period, valued at roughly $145 million at 2022 prices. With the CIP gone, those teams no longer receive that predictable revenue stream.
Van Epps estimates that sustaining ten or more client teams plus associated infrastructure projects requires around $30 million per year. The Ethereum Foundation's own grant data points to a significant gap. In Q1 2026, the Foundation disbursed $9.856 million through its Ecosystem Support Program, covering zero-knowledge proofs, cryptography, client development, and Layer 2 infrastructure. That grant envelope is spread across multiple categories, meaning the portion directed specifically to core client teams represents a fraction of the $30 million annual threshold Van Epps describes as necessary.
The Foundation has also adopted what it calls a "Subtraction" strategy, deliberately reducing its direct funding and operational footprint to push the broader ecosystem toward self-sufficiency. The strategy was formally articulated in "The Promise of Ethereum," a document published on March 13, 2026, which introduced the CROPS principles: Censorship Resistant, Open Source, Private, and Secure. Vitalik Buterin has publicly framed the EF as "one node inside Ethereum rather than its permanent steward."
The staffing picture adds context to the funding warning. At least five senior contributors have departed the Foundation since January 2026, including co-executive director Tomasz Stańczak, board co-steward Josh Stark, and researchers Barnabé Monnot and Tim Beiko. Van Epps himself left in April 2026.
Stark said he had "no plans for the future, other than taking a long break to reset and spending time with family."
Van Epps, for his part, publicly described EF leadership's association with a Milady NFT collection as "baffling and sad" when he left.
Not everyone sees cause for alarm. Joe Lubin, Ethereum co-founder and Consensys CEO, told CoinDesk on June 7 that "Ethereum Foundation cuts and departures aren't a crisis."
The next major protocol upgrade, Glamsterdam, has been pushed to Q3 or Q4 2026 from an earlier potential June launch date. The delay extends the period during which client teams must operate without CIP income, adding further pressure on groups already adjusting to the post-CIP environment.
On-chain metrics show the network remains large but operating under financial pressure. ETH is trading around $1,803, down approximately 64% from its August 2025 all-time high near $4,954.
Ethereum's DeFi total value locked sits at roughly $45.4 billion, according to DeFiLlama data from May 2026, but its share of total DeFi TVL has slipped from 63.5% at the start of 2025 to around 54% as application-specific chains take market share.
Approximately 30% of all ETH supply is now staked, a record level. Ethereum still commands more than 60% of the global blockchain developer market, with cumulative developer participation surpassing one million.
The funding question carries direct consequences for developers in South Asia and Africa, two regions where Ethereum-based infrastructure is growing quickly. India's blockchain market is projected to reach $53 billion by 2030; the government launched the Blockchain India Challenge through its Ministry of Electronics and Information Technology in February 2026, and India has been selected to host major Ethereum events based on its developer community size.
Across Africa, universities in Nairobi, Lagos, and Cape Town now run blockchain curricula, and the University of Namibia recently launched what is described as Africa's first master's degree in blockchain.
Surveys of African business decision-makers identify cross-border payments, a use case anchored in stablecoin and EVM-compatible infrastructure, as a key blockchain priority. A reduction in client team diversity would raise the risk of software bugs or consensus failures that could interrupt services for users across both regions, analysts warn.
Van Epps is backing Protocol Guild as a partial solution. The initiative uses a smart contract to distribute donations from external projects and DAOs directly to active Ethereum Layer 1 contributors, weighted by tenure.
The mechanism is designed to operate independently of the Foundation. It has not yet reached the scale needed to replace CIP's systematic validator-backed income, but Van Epps argues it offers the "long-term, onchain funding" that one-off grants cannot provide.
Whether protocols and projects building on Ethereum's $45 billion DeFi ecosystem will contribute enough to close a $30 million annual gap is the open question heading into the second half of 2026.
