Ethereum's Layer 2 Boom: What it Means for Fees and Value Capture

Ethereum's scaling phase is in full swing as Layer 2 networks reduce transaction costs and move more activity away from the mainnet. The shift has led to a significant drop in Ethereum fees, with gas prices falling by a considerable margin compared to previous periods of intense mainnet congestion.

The growth of Layer 2 networks has been driven by the adoption of rollups, which batch multiple transactions into a single mainnet settlement, thereby reducing demand for block space on the Ethereum mainnet. This approach has enabled the ecosystem to scale without overwhelming the settlement layer, with base, Arbitrum, and Optimism playing critical roles in facilitating this growth.

As Layer 2 networks continue to expand, they are changing the value capture dynamics of the network. While users benefit from cheaper fees on these alternative settlement layers, Ethereum still captures value from Layer 2 growth through blob fees, which enable rollups to post transaction data on the Ethereum blockchain.
