Dynamic Fee Structure for the Ethereum Application Layer

Two Ethereum community members, Kevin Owocki and Devansh Mehta, have proposed a dynamic fee structure for the Ethereum application layer to strike a balance between revenue generation for app builders and fairness in fee extraction.

In a proposal titled "Toward a More Balanced App Layer Economy," Owocki and Mehta suggest a simple equation that uses a square root function to proportionally lower the percentage of fees as the funding capital allocated to a particular project increases.

"We can modify the standard fee structure to better balance revenue generation with fairness in fee extraction," the authors stated.

"Let f be the percentage of collected fees that go to the protocol and c be the total funding capital allocated to a particular application (e.g., via grants, venture capital, community fundraising). Then we can use the following equation to adjust the percentage of collected fees according to the relative funding of an application:"

f = min(100,80 + 100 * sqrt(c/1e6)) / 10

The authors explained that once a particular application's funding crossed the $10 million level, the fees would be capped at 1%, ensuring that small app builders can easily develop decentralized applications without encountering excess fees. However, the proposal also encourages project and funding growth by capping the fees as developers scale their applications.

"We can set a lower limit on f to prevent it from getting too small. Perhaps f >= 1% is reasonable. We can also set an upper limit on f to avoid having it get too large. Perhaps f <= 10% is a reasonable upper bound. Finally, we can set a maximum funding threshold at which point the percentage of collected fees is no longer reduced. Perhaps this threshold is around $1 billion in funding capital, at which point it may be reasonable to begin collecting a larger percentage of collected fees to support the ecosystem at large.

"The goal is to strike a better balance between the economics of small app builders and the economics of large-scale applications and institutions that are building on the Ethereum ecosystem. We can do better than continuing to lower the percentage of collected fees as a desperate measure to try and keep pace with other emerging blockchains."

Owocki and Mehta's proposal to balance revenue generation and profitability among Ethereum's app builders strikes at the heart of the emerging concerns about economic imbalances and anomalies in the Ethereum ecosystem.

As Ethereum faces increasing pressure from high-throughput and low-cost blockchain networks to maintain its position as the dominant Web3 chain, it must maintain the attractiveness of its ecosystem for developers, users and institutions.

The threat posed by Solana and other rising smart contracts platforms is evident in the stark difference in developer activity between the two ecosystems. In 2024, the Solana ecosystem onboarded more developers than the Ethereum network. According to Santiment, Solana gained 7,625 new developers, while Ethereum gained 6,456.

Despite the surge in software developers building on the Solana network in 2024, Ethereum remains the dominant ecosystem for attracting developer talent, although the 2024 data shows that this position is no longer uncontested.

However, the threat posed by Solana and other emerging networks is pushing institutions to diversify their Web3 investments and scale back their contributions to the Ethereum ecosystem.

According to onchain analytics firm Santiment, Ethereum fees dropped to five-year lows in April 2025 due to low activity on the Ethereum base layer resulting from reduced demand for smart contract operations like decentralized finance.

This reduced demand is leading to many institutions scaling back their Ether (ETH) holdings or selling off portions of their investment as investor sentiment toward the first-ever smart-contract platform continues to erode without any clear catalysts for a reversal.
