The new all-time high for network activity in the Ethereum ecosystem underscores the platform’s continued dominance in the decentralized application and smart contract sectors. A staggering 15.4 million active addresses buzzed with activity just last week. In stark contrast to the Layer 1 noise, Ethereum’s Layer 2 networks hummed along at a record 6.65 times more activity than Ethereum’s own Layer 1 (which is quite the circumspect conundrum, if you think about it). All of this is good news for Ethereum—an almost undisputed foundation for on-chain activity and value—and not just because it makes a good segue into the not-so-nice underlying economic picture. Record Activity and L2 Growth Signal Strength—And Strain The rapid growth in active addresses and L2s indicates that user demand and innovation across Ethereum are off the charts. At the same time, however, the unmitigated success of Ethereum and L2s leads to intensifying economic pressure for the Ethereum base layer. As Ethereum scales and becomes more friendly to L2s—thanks to the development of such technologies as “blobspace”—it is giving up the most profitable parts of its economy: gas fees during times of network congestion and the fat margins associated with MEV (Maximum Extractable Value). Ethereum Ecosystem just hit a new ALL-TIME HIGH! 15.4M active addresses +62.7% surge in just 7 days Layer 2 dominance at record 6.65x ETH is scaling and thriving. Ignore the noise. pic.twitter.com/Lb1XqSiJj3 — Leon Waidmann (@LeonWaidmann) April 28, 2025 Ethereum is positioning itself as a settlement and data availability layer for the long-term scalability of DApps. The immediate implication of this is that most of the transaction revenue is now being captured by Ethereum’s Layer 2 solutions. These solutions, in particular, the recent rollup designs, are functioning quite well; in fact, they’re doing so well that they’re returning over 90% profit margins, which is quite a bit lower than what was being returned last year. And on top of that, these profit margins are being returned by Layer 2 solutions that are now processing the bulk of transactions in the Ethereum economy. Compounding this issue further is the growing trend of apps seizing their own MEV, rather than permitting L1 validators to extract it. Innovations like Aave’s integration with Chainlink’s Secure Value Recovery (SVR) allow DeFi protocols to directly reclaim MEV that would otherwise leak to miners or validators. Moreover, major applications like Uniswap are considering or have already launched their own app-specific chains or L2s—pushing even more value capture away from Ethereum’s base layer. The challenge with Ethereum’s economics today is that $ETH is losing ground on two fronts currently Ultrasound Money (Revenue): L1 revenue has been deteriorating due to Ethereum forfeiting the most valuable part of the stack (congestion gas pricing fees + MEV) to L2s, while… pic.twitter.com/5QuGHBov6N — Zach Rynes | CLG (@ChainLinkGod) April 28, 2025 The Revenue Challenge: Can Ethereum Scale Fast Enough? This shift in value flow means Ethereum must now support an “insane” amount of on-chain volume and activity to sustain a meaningful revenue model. In contrast to its 2021 peak, when high fees created a lucrative environment for the protocol and its validators, today’s race to lower transaction costs—while positive for users—threatens the sustainability of Ethereum’s core economics if the volume doesn’t scale up proportionally. The real success of Ethereum’s scaling roadmap may undermine its capacity to produce sizable revenue unless it hits an adoption level well above present standards. In a world where L2s are hyper-efficient, Ethereum must ensure that a truly massive volume of transactions get settled on-chain to counteract the ever-thinning margins we’re taking per transaction. Ethereum faces a serious revenue problem. That’s hardly news. But the stakes are higher than they might seem, as innovations like account abstraction and paymaster systems take away the need to hold ETH for gas. If access to Ethereum’s Layer 2 (L2) networks and every asset issued on Ethereum doesn’t require holding Ethereum itself, what’s the incentive to maintain the token as even a store of everyday value? As the very systems that Ethereum enabled become ever more sophisticated, L2s still appear to be in their infancy. A Modest ETF Rebound Offers a Glimmer of Optimism Notwithstanding these structural issues, Ethereum was able to bask in a ray of sunshine last week. Following not one, but eight full consecutive weeks of outflows, U.S.-based spot Ethereum ETFs recorded a net inflow of $157 million. While this would be modest in any scale of comparison to the mega-inflows being directed toward Bitcoin ETFs, it could well be a nascent turn in institutional sentiment toward Ethereum itself. The renewed interest could also conflate something as well: Ethereum’s long-term potential, especially as the network itself evolves toward a scalable, modular architecture. During the last trading week (April 21 to April 25, ET), spot Bitcoin ETFs recorded a net inflow of $3.06 billion, marking the second-highest weekly inflow in history. Spot Ethereum ETFs ended an eight-week streak of net outflows, posting a net inflow of $157 million last week.… — Wu Blockchain (@WuBlockchain) April 28, 2025 Nevertheless, this by itself might not suffice to counter the imminent problems facing Ethereum’s economic design. The network has to find a way to balance the conflicting demands of scalability and decentralization against the not-too-distant prospect of its native token losing much of its value. To summarize, Ethereum is at a crossroads. Its ecosystem has never been more active or dominant, yet its economic underpinnings seem to be shifting from the original design. If Ethereum can adapt its economic model to fit with its technological trajectory, it will have met one of the most important challenges facing any blockchain platform.
