Ethereum L2 Economics 2026: Divergent Models Among Arbitrum, Base and Optimism
Base launches Azul upgrade on mainnet advancing decentralization. Arbitrum leads ethereum l2 revenue through highest transaction volume. Layer 2 scaling
Summary
- Base launches Azul upgrade on mainnet advancing decentralization.
- Arbitrum leads ethereum l2 revenue through highest transaction volume.
- Layer 2 scaling now dominates activity as optimism economics and peers diverge.
Base launched its Azul upgrade on mainnet in 2026. The upgrade brought multiproofs and a fresh client stack. It became the first independent network upgrade for the Coinbase-backed rollup.
This step pulls Base off the standard OP stack. It opens tighter links to Ethereum mainnet. Other L2s head down their own routes.
Revenue data from early 2026 already shows clear splits across the group.
Context
Ethereum Layer 2 rollups have left experiments behind. They now run separate economic models. 2026 figures confirm Arbitrum brings in the largest revenue among ethereum l2 projects.
Base and Optimism sit behind in volume. Each picks its own technical path.
Mainnet revenue fell from $147M per month in January 2025 to $24M per month in April 2026. L2 revenue traced the same drop. Activity has shifted.
Each rollup now earns in its own style.

Arbitrum holds the revenue lead through deep DeFi liquidity and steady transaction counts. Optimism leans on sequencer fees and ecosystem grants. Base gains from Coinbase reach but must prove it can keep growing on its own.
The models split further on fees, governance, and client choices. Data through April 2026 shows no single path has won yet.

Outlook
Teams watch whether Base keeps its cost and speed edge after the independent stack. They also check if Arbitrum's revenue lead narrows. Optimism and newer players adjust their models in response.
