The Ethereum community is currently grappling with significant discussions sparked by a substantial 654 million dollar Ether transaction made by the Ethereum Foundation. This event ignited intense discussions surrounding fair compensation for developers, the need for greater transparency, and questions about leadership within the Ethereum project. These debates led to the highly publicized departure of core developer Péter Szilágyi and a resurgence of critiques regarding the project’s governance model.
Concurrently, Polygon’s much-anticipated AggLayer upgrade has experienced launch postponements and technical instabilities, further fueling the ongoing debate about the alignment of Layer-2 solutions, the potential for fragmentation, and the degree of support the Ethereum Foundation should provide to external Layer-2 projects.
These recent developments, coupled with the price volatility of the POL token migration, the continuing challenges of balancing centralization on the Ethereum mainnet with the autonomy of Layer-2 networks, and reactions to the Ethereum Foundation’s prior executive restructuring, have intensified the pressing conversations about the future direction of Ethereum and the long-term, sustainable development of its scaling solutions ecosystem.
Ethereum Family Dispute
The architecture for scaling Ethereum has evolved from a purely technical matter to a complex issue with economic and political dimensions. This shift became evident when Vitalik Buterin publicly praised Coinbase’s Base network for “doing things the right way.” This occurred just weeks after Sandeep Nailwal, founder of Polygon, assumed the role of CEO at the Polygon Foundation, issuing warnings regarding Ethereum’s potentially problematic direction concerning Layer-2 (L2) solutions, describing the situation as “existential.”
The core question emerging from these diverging viewpoints is whether Ethereum will establish standardized methods for Layer-2 networks to generate and settle value, or if it will witness a fragmentation of liquidity into separate systems that bypass rather than utilize the main Ethereum network.
This tension came into focus through three key events during the middle of 2025. On June 11, Nailwal assumed leadership of the Polygon Foundation amid a strategic realignment, positioning Polygon as more independent from Ethereum’s rollup-centric approach.
Polygon launched AggLayer version 0.3 on June 23, pushing forward chain-agnostic interoperability with Polygon Proof-of-Stake (PoS). The connection was scheduled by the end of Q3, but this hadn’t happened at press time.
Buterin’s public endorsement of Base in September brought back old debates about whether Ethereum’s leadership is favoring specific Layer-2 solutions. It also amplified previous disagreements stemming from Nailwal’s questioning of the insufficient recognition from Ethereum core developers and his concerns that negative views on Layer-2 solutions could damage the social fabric of the ecosystem.
Data from L2BEAT indicates that Arbitrum and Base command the largest proportion of value secured on Ethereum Layer-2 networks, with OP Mainnet and Linea following behind.
The Polygon zkEVM has a materially smaller market share than its Proof-of-Stake chain, both in terms of total value locked and transactional use.
Sequencer profit dashboards from Dune reveal that Base and Arbitrum generate the majority of net sequencer earnings after accounting for Layer-1 data costs, with Base consistently demonstrating high profits through the late summer of 2025.
Buterin’s roadmap commentary from 2025 emphasizes simplification, resilience of the mainnet (including privacy enhancements), and a Layer-2 user experience that relies more heavily on the security guarantees provided by Layer-1.
This guidance establishes what Ethereum leadership considers “good L2 citizenship”: canonical fraud or validity proofs, reliance on Ethereum for data availability, and alignment with emerging standards for light clients and shared sequencing.
Polygon’s AggLayer is striving for chain-agnostic shared liquidity, positioning itself alongside Ethereum’s rollup focus rather than within it.
Polygon’s Proof-of-Stake chain is transitioning towards zkEVM validium integration, which utilizes alternative data availability layers.
Three Paths for Fee Capture and Market Structure
The next six to twelve months will be crucial in determining whether Ethereum can standardize value flows across different Layer-2 architectures.
In a soft-alignment scenario, with a 50% to 60% likelihood, the Ethereum mainnet captures 25% to 40% of the Layer-2 gross fee revenue as improvements in blob compression and data availability stabilize costs.
Base and Arbitrum retain 60% to 70% of Layer-2 net profits, with OP Stack proliferation sustaining Base’s distribution advantage through Coinbase’s on-ramp infrastructure.
Polygon’s AggLayer connects its Proof-of-Stake ecosystem and CDK chains to stimulate cross-chain liquidity growth. However, transaction flows that are native to Ethereum prioritize OP Stack clusters due to canonical settlement guarantees.
In this situation, POL token performance hinges on the ecosystem’s extensive reach rather than its adherence to rollup standards.
A fragmentation scenario, with a 20% to 25% probability, involves Ethereum mainnet data availability revenue underperforming as activity shifts to non-Ethereum data availability layers, including validiums and alternative availability services.
Layer-1 captures only 15% to 25% of Layer-2 gross fees, as competing liquidity centers, such as AggLayer, OP Superchain, and application-specific ZK rollups, divide users across incompatible standards.
Maximal extractable value (MEV) smoothing across Layer-2 solutions lags behind technical deployment, worsening the user experience during cross-rollup operations.
In this scenario, Polygon gains attention with chain-agnostic routing, as the Proof-of-Stake migration to AggLayer establishes a parallel liquidity hub that is somewhat disconnected from Ethereum’s social consensus mechanisms.
A re-convergence under Ethereum-first norms carries a 20% to 25% probability, driven by stronger Layer-2 minimalism through the use of light clients, fault and validity proofs, and shared sequencing or proposer-builder separation, which also extends to rollups.
The mainnet captures 35% to 50% of Layer-2 gross fees as infrastructure standards tighten. Base and Arbitrum consolidate over 70% of Layer-2 profit share, with OP Stack standardization and cross-rollup bridging reducing friction for users moving assets between chains.
Polygon tightens Ethereum alignment through ZK proofs and Ethereum data-availability lanes for flagship chains while positioning AggLayer as a user-experience differentiator rather than a sovereignty play that competes with mainnet settlement.
Value Capture and Distribution Dynamics
Ethereum investors are confronted with a value capture question directly related to Layer-2 architecture choices.
A greater reliance on Ethereum’s data availability (DA) and canonical proof systems increases mainnet fee capture, with blob utilization trends relative to Layer-2 compression advances determining whether Ethereum’s toll-road economics expand or erode.
Cross-rollup MEV markets are still in their early stages, but if Ethereum-aligned proposer-builder separation norms extend to Layer-2 sequencers, extractable value flows back to Ethereum validators. Alternative scenarios where MEV concentrates in Layer-2 silos reduce the mainnet’s economic gravity.
Layer-2 tokens, including ARB, OP, and POL, derive their narratives from the profitability of the net sequencer, creating sensitivity to monthly profit leaderboards that show Base, operating without a native token, setting user-experience standards that pressure tokenized rollups to justify their value through revenue sharing, grants, or governance power.
Polygon’s investment case improves if AggLayer drives composability that converts to retained liquidity rather than transient bridge volume, regardless of its ranking as the largest pure rollup by traditional definitions.
Monitoring AggLayer connection milestones and Proof-of-Stake migration progress provides leading indicators for this scenario.
Builders optimizing for distribution confront a pragmatic calculation where OP Stack and Base infrastructure win near-term user acquisition through streamlined on-ramps and Layer-2 to Layer-2 liquidity routing.
Teams prioritizing user experience and cross-chain operability may outperform those focused on doctrinal alignment debates, particularly as multichain user experiences remain challenging and network effects favor the largest distribution hubs.
Centralization and Interoperability as Structural Forces
Coinbase’s Base receiving public praise from Buterin sharpens debates over corporate influence versus Ethereum’s social fabric, particularly as global regulatory frameworks, including MiCA and FATF guidance, favor KYC-friendly Layer-2 solutions with clear operational entities.
Polygon’s chain-agnostic AggLayer vision competes with OP Superchain and ZK rollup hubs in an interoperability arms race analogous to mobile platform competition, where walled gardens are contrasted with open liquidity meshes.
The Ethereum mainnet is positioned as foundational infrastructure rather than an exclusive settlement layer.
User gravity concentrates in networks that solve multichain pain points, with Vitalik and Ethereum core researchers pushing for a simplified, Layer-1-secured L2 user experience.
If user-experience standards unify around common light-client implementations and proof verification, network effects compound advantages for the largest distribution hubs, including Base and Arbitrum.
Polygon’s alternative path depends on AggLayer establishing sufficient cross-chain liquidity, enabling developers and users to opt for composability over canonical Ethereum settlement.
The outcome determines whether Ethereum operates as a standardized settlement layer capturing predictable fees from aligned rollups, or as one option among competing architectures where liquidity and users distribute across networks with varying degrees of mainnet dependency.
Sequencer profit concentration, blob utilization rates, and AggLayer adoption metrics through mid-2026 will clarify which path the ecosystem follows, and whether loyalty to Ethereum becomes a measurable economic parameter rather than a social-layer assumption.
