Ethereum's Builders May Be Running Out of Money, Former Foundation Contributor Warns

Ethereum's biggest challenge over the next year may not be scaling, competition from rival chains, or even regulation. It could be funding.

Former Ethereum Foundation contributor Trenton Van Epps has warned that the network's core development ecosystem may be heading toward a funding shortfall, raising concerns about how Ethereum's most critical infrastructure will continue to be maintained and upgraded in the years ahead.

In a recent blog post first reported by Cointelegraph, Van Epps said Ethereum could face a "slow-burning funding crisis" within the next three to nine months as traditional sources of support for core contributors begin to dry up.

According to Van Epps, the expiration of Ethereum's Client Incentive Program earlier this year, combined with reduced spending from the Ethereum Foundation, has left a significant funding gap across the network's development ecosystem. He estimates that maintaining Ethereum's core development efforts could require roughly $30 million annually.

While the figure could not be independently verified, the warning arrives at a time when questions surrounding Ethereum Foundation finances and long-term sustainability are becoming increasingly visible.

Leadership Changes Add to Uncertainty

The funding concerns come amid a broader period of transition inside the Ethereum Foundation.

This week, Ethereum Foundation co-executive director Hsiao-Wei Wang announced plans to step down from her role, adding to a growing list of departures from the organization during 2026.

The latest exit brings the estimated number of layoffs and departures at the foundation to nearly 20 this year, fueling debate about how Ethereum's primary stewardship organization is evolving as the network matures.

While Ethereum has increasingly embraced decentralization across its infrastructure and governance, the foundation still plays a central role in funding research, client development, ecosystem grants, and long-term protocol initiatives.

Vitalik Buterin Signals a Shift Toward Sustainability

The concerns also follow recent comments from Ethereum co-founder Vitalik Buterin regarding the foundation's treasury strategy.

In May, Buterin noted that the Ethereum Foundation controls only a small fraction of ETH's total supply, estimated at roughly 0.16%, significantly less than the treasury holdings maintained by some competing blockchain foundations.

He argued that the foundation was never intended to permanently fund every aspect of Ethereum's growth and that many of its original objectives—including shepherding Ethereum through major roadmap milestones—had largely been completed.

"As a result, the EF is choosing longevity over breadth," Buterin wrote, explaining that the organization is becoming more conservative with its resources.

That shift has already become visible on-chain.

The Ethereum Foundation recently unstaked tens of thousands of ETH and completed a 10,000 ETH over-the-counter sale to Bitmine, one of the largest corporate holders of Ether. Blockchain analytics firms suggested the moves may have been intended to provide additional operational funding while reducing reliance on future token sales.

Who Pays for Ethereum?

The debate highlights a challenge that many decentralized networks eventually face.

While blockchains often launch with foundation funding, venture capital support, and token treasuries, sustaining development over decades requires a more permanent economic model.

Bitcoin relies heavily on corporate sponsors, nonprofits, and independent contributors. Solana has increasingly benefited from ecosystem funds and venture-backed companies. Ethereum sits somewhere in the middle, with much of its development historically supported through foundation grants and ecosystem initiatives.

As Ethereum approaches its second decade, the question is becoming more urgent: who funds the builders responsible for maintaining the world's largest smart contract network?

Van Epps believes the answer will need to emerge soon.

If alternative funding mechanisms fail to materialize, Ethereum's developer ecosystem could face increasing pressure just as competition among Layer 1 networks, institutional adoption, and global demand for blockchain infrastructure continue to accelerate.

For a network securing hundreds of billions of dollars in value, the challenge may not be technological. It may be ensuring the people building Ethereum can continue to do so.
