Layer 2 Ecosystem Consolidates Around Base and Arbitrum, Leaving Smaller Rollups Behind

The Ethereum Layer 2 landscape is undergoing dramatic consolidation, with Base and Arbitrum now accounting for more than 80% of layer-2 DeFi total value locked (TVL), according to DefiLlama data. This concentration has left smaller scaling solutions struggling to maintain liquidity and user activity. Over the past six months, networks including Linea, World Chain, Starknet, and Mantle have all seen declining bridge deposits—Linea's deposits, for example, fell from $976 million in November 2025 to $367 million in May 2026, a decline of more than 60%.

The shift reflects a broader market realization that not all Layer 2s serve necessary functions. Market participants are consolidating around proven ecosystems with established DeFi infrastructure, developer activity, and user bases. The data suggests that general-purpose rollups without differentiated value propositions face mounting pressure to justify their existence. Simultaneously, the market is shifting toward specialized use cases: Layer 2 activity increasingly gravitates toward payments, stablecoins, and tokenized assets rather than general smart contract platforms.

This consolidation pattern mirrors natural competitive dynamics in infrastructure—winners accumulate network effects while smaller players struggle. The trend has significant implications for Ethereum's scaling narrative: instead of a fragmented multichain future, the ecosystem appears to be settling on a hub-and-spoke model centered on Ethereum mainnet with one or two dominant Layer 2 solutions.

Protocol & Development

• Ethereum Foundation Leadership Changes Draw Vitalik's Comment: Vitalik Buterin acknowledged the Ethereum Foundation's departures in 2026, noting that the organization will "shrink and sell less ETH" following at least 8 senior exits. Buterin indicated this reduction in institutional selling could have positive implications for ETH's market dynamics, though leadership uncertainty remains a topic of ecosystem discussion.

• FOCIL Officially Added to Hegota Upgrade Roadmap: The Ethereum development community has officially scheduled FOCIL (Forward-Only Consensus In Layers) as the consensus-layer headliner for the upcoming Hegota upgrade, targeted for late 2026. Vitalik Buterin has positioned this upgrade as reinforcing Ethereum's "cypherpunk principles," marking a significant shift toward censorship resistance at the protocol level.

• Post-Quantum Research Initiative Underway: Following the Ethereum Foundation's establishment of a dedicated post-quantum research team, Vitalik Buterin has unveiled a multi-step roadmap to counter quantum computing threats to the network. This proactive approach reflects growing recognition that long-term protocol security requires planning for cryptographic vulnerabilities decades in the future.

DeFi Pulse

• Total Ethereum DeFi TVL: Data from DefiLlama shows Ethereum DeFi remains the dominant ecosystem, though exact current TVL figures require direct access to the dashboard.

• Top Movers: Base and Arbitrum continue to capture the vast majority of Layer 2 DeFi activity, with smaller protocols on Linea, StarkNet, and Mantle experiencing significant TVL outflows as users consolidate around dominant platforms.

• Layer 2 Fee Reductions: Ethereum Layer 2 transaction fees have dropped further following blob capacity expansion upgrades, improving economic efficiency for everyday users and DeFi participants across rollup networks.

Layer 2 & Scaling

• L2 Market Shift Toward Payments and Stablecoins: The Layer 2 ecosystem is strategically repositioning away from general-purpose smart contract platforms toward specialized use cases in payments infrastructure and stablecoin settlement. This shift reflects market demand for specific Layer 2 applications rather than generic scaling solutions.

• L2BEAT Activity Metrics: Rollups are processing significant transaction volumes with a reported scaling factor of approximately 60x relative to Ethereum mainnet, demonstrating the continued importance of Layer 2 infrastructure despite consolidation pressures.

• Blob Capacity Impact on Transaction Economics: The expansion of blob capacity has meaningfully reduced Layer 2 transaction costs, improving user economics and potentially reversing some of the TVL exodus experienced by smaller chains. This technical improvement addresses one of the key pain points driving users away from lesser-used rollups.

What to Watch

• Hegota Upgrade Development: Late 2026 timeline for the Hegota upgrade with FOCIL as the centerpiece—monitor Ethereum core dev calls for progress updates and potential timeline adjustments.

• Layer 2 Consolidation Pace: Track whether smaller rollups can differentiate through specialized use cases or whether consolidation continues accelerating toward a duopoly around Base and Arbitrum.

• Ethereum Foundation Stability: Following multiple 2026 departures, watch for official announcements regarding new leadership hires and strategic direction clarification.

• Post-Quantum Security Planning: Monitor progress on the Ethereum Foundation's post-quantum research initiative and any proposed protocol changes for cryptographic resilience.

Reader Action Items

1. Reassess Layer 2 Exposure: If you hold tokens or deploy liquidity on smaller Layer 2 solutions (Linea, StarkNet, Mantle), evaluate whether differentiated use cases justify continued exposure given ongoing TVL outflows and consolidation trends.

2. Monitor FOCIL and Hegota Timeline: Developers and protocol participants should review Ethereum core dev discussions on the roadmap to understand implications of consensus-layer changes for applications and infrastructure.

3. Track Ethereum Foundation Updates: Stay informed on official EF announcements regarding leadership changes and strategic priorities, as institutional direction shifts may impact grant funding and research priorities in the ecosystem.
