Activity across Ethereum's rollup ecosystem remains heavily concentrated, with the two networks together holding more than four-fifths of all layer-2 DeFi value locked.
<p>Ethereum's layer-2 ecosystem has consolidated sharply around just two networks, with Base and Arbitrum together now accounting for more than 80% of all DeFi value locked across layer-2 rollups, according to on-chain data.</p>
<p>The concentration marks a notable shift for a segment of the market that once featured dozens of competing rollups pitching similar value propositions -- lower fees and faster transactions than Ethereum's base layer, secured by periodically settling proofs back to mainnet. In practice, liquidity and developer activity have gravitated toward a small number of networks with the deepest existing DeFi ecosystems and the strongest exchange and wallet integrations, making it progressively harder for newer or smaller rollups to compete on network effects alone.</p>
<p>Base, incubated by Coinbase, has benefited from direct integration with one of the largest crypto exchanges' user base, giving it a distribution advantage few competing rollups can match. Arbitrum, one of the earliest general-purpose rollups to launch, has retained its position largely on the strength of an established DeFi ecosystem that includes some of the largest lending and trading protocols operating on any layer-2 network.</p>
<p>The trend reflects a broader theme playing out across Ethereum's scaling roadmap: rollups have become the primary way most transactions actually get executed, with layer-2 networks collectively processing more activity than Ethereum's own mainnet. But as that activity concentrates into fewer, larger networks, it raises questions about how much genuine differentiation remains among smaller general-purpose rollups still competing for the same liquidity and users.</p>
<p>The consolidation has implications beyond just DeFi metrics. Restaking protocols, data availability providers and other infrastructure built to serve the layer-2 ecosystem are increasingly designing their offerings around the assumption that Base and Arbitrum will remain the dominant venues, rather than spreading integration efforts evenly across the long tail of smaller rollups still active on Ethereum.</p>
<p>For newer entrants, the path forward increasingly looks like specialization -- targeting specific use cases, geographies or application categories -- rather than attempting to compete head-on with Base and Arbitrum as general-purpose alternatives. Whether that strategy proves durable, or whether Ethereum's layer-2 landscape continues consolidating further around an even smaller set of winners, is likely to remain one of the more closely watched dynamics in Ethereum's scaling story through the rest of 2026.</p>
