Ethereum’s L2 rollups now control 83% of DeFi TVL as Base, Arbitrum and Optimism dominate, while ETH price slipped 38% from its August peak to $3,056.
Ethereum’s Layer‑2 rollups now command roughly 83 % of all L2 DeFi total value locked, with Base, Arbitrum and Optimism leading the pack, as the network’s price fell from a $4,953 high in August to about $3,056 in mid‑November—a 38 % drop from the peak and 39 % below that level [2].

The 21shares mid‑year report notes that under‑differentiated rollups are failing to survive, with active user metrics and liquidity concentrating on three networks [1]. Base, Arbitrum and Optimism together hold the majority of L2 DeFi TVL, confirming a structural shake‑out that mirrors comments from Ethereum co‑founder Vitalik Buterin. Isolated scaling chains with limited distribution models are now facing attrition or migration to app‑chains.
Ethereum’s price trajectory over the past six months illustrates the market’s mixed reaction to L2 growth. ETH rose from $3,600 in May 2025 to a high of $4,953 on August 24, then fell to $3,064 by early November, settling around $3,056 on November 16 [2]. Analysts attribute the pullback to profit‑taking and concerns that L2s siphon fee revenue and token burns away from the main chain, dampening ETH’s value model despite the scalability gains.
While L2s boost transaction throughput—Arbitrum processes roughly 3.4 million daily transactions and locks about $20 billion, Optimism handles close to 1 million daily, and Base drives roughly 8 million retail transactions—most of this activity bypasses the Ethereum mainnet, limiting fee returns to ETH holders [2]. Meanwhile, 21shares reports that total global crypto ETP assets under management sit at $140 billion, down 15 % YTD, yet net BTC holdings remain near all‑time highs, indicating institutional capital’s resilience amid volatility [1].
The dominance of a few L2s underscores a maturing scaling ecosystem, but the ongoing price decline raises questions about whether the shift of activity off‑chain will ultimately erode Ethereum’s fee‑based security model or simply reflect a temporary market adjustment.

Because Layer 1 designs that verify every transaction on‑chain limit throughput, leading to congestion, high fees, and slower confirmations as usage grows.
They process transactions off‑chain and then provide cryptographic proofs or compressed summaries to the Layer 1 chain, which validates and finalizes the state changes.
The sources describe state channels, which allow off‑chain trades between locked participants, and rollups, which bundle and execute transactions off‑chain before L1 verification.
