Ethereum's Layer-2 Ecosystem Plunges by Over 90% Amidst Growing Competition

Ethereum's (ETH) Layer-2 ecosystem has been hit hard this year, with activity plummeting by over 90% from its highs in early 2026. This decline is largely due to a combination of factors, including the drop in on-chain activity, leadership transitions within the Ethereum Foundation, and increasing competition from other blockchain networks.

The total value locked (TVL) in Ethereum's Layer-2 ecosystem has dropped significantly, falling from $48 billion earlier this year to around $5 billion. Despite this decline, Optimism, Base, and Arbitrum continue to dominate the ecosystem, accounting for approximately 96% of the remaining L-2 liquidity with a combined TVL of $4.8 billion.

Analysts attribute the drop in activity to capital outflows, as users have sought opportunities elsewhere or bridged assets back to Ethereum's mainnet and competing blockchains. This trend is further exacerbated by the growing fragmentation within the Layer-2 ecosystem, with over 73 active rollups on Ethereum but decreasing liquidity.

The emergence of alternative blockchain networks, such as Robinhood's chain, has also contributed to this shift in user activity. While Robinhood's chain initially gained traction, its relatively low fee generation compared to Ethereum raises questions about the long-term viability of Layer-2 networks and their ability to return economic value to the base chain.

As institutions like DTCC and JPMorgan expand their tokenization initiatives across multiple public blockchains, Ethereum's dominance is being challenged. The Ethereum Foundation's leadership transitions and the adoption of new approaches to reduce transaction fees further contribute to the uncertainty surrounding the network's future.
