Ethereum’s layer‑2 market narrows, with Base and Arbitrum now holding over 80% of TVL and smaller rollups seeing deposits plunge 60% since late‑2025.
Ethereum’s layer‑2 ecosystem is entering a consolidation phase, with Base and Arbitrum together accounting for more than 80% of total value locked (TVL) on rollups, while smaller networks such as Linea have seen bridge deposits tumble over 60% since November 2025 [2].

Base and Arbitrum’s combined share of TVL reflects a sharp skew toward a handful of networks after years of rapid rollup launches. DefiLlama data cited by CoinDesk shows that these two chains now host the bulk of Ethereum‑L2 DeFi activity, effectively crowding out many newer general‑purpose chains [2]. This concentration is reinforced by on‑chain metrics: bridge deposits into Linea fell from $976 million in November 2025 to $367 million in May 2026, a decline of more than 60% [2]. Similar downward trends have been observed for World Chain, Starknet and Mantle, indicating that liquidity is increasingly flowing to the dominant rollups.
The surge of new rollups was driven by the ease of deploying chains using stacks such as Optimism’s OP Stack, Arbitrum Orbit and zkSync. However, as Ben Fisch, co‑founder of Espresso Systems, notes, “there were way too many general‑purpose layer‑twos… there’s no reason to have many, many versions of the same thing” [2]. Market participants are now favoring specialized applications—particularly payments and stablecoins—over broad‑scope platforms, a shift echoed by recent project pivots away from generic branding toward niche use cases [2].
Despite the rollup shake‑up, Ethereum’s core function as the settlement layer endures. The network continues to process the final proofs from rollups, securing their transactions while offering a shared security base. This underlying role supports the view that Ethereum will stay central to DeFi and emerging stablecoin payments, even as the layer‑2 landscape contracts [1].
| Metric | Value |
|---|---|
| Linea bridge deposits (Nov 2025) | $976 million |
| Linea bridge deposits (May 2026) | $367 million |
| TVL share of Base + Arbitrum | > 80% |
The emerging concentration suggests that Ethereum’s layer‑2 future may be defined by a few well‑capitalized rollups rather than a sprawling zoo of general‑purpose chains, leaving open the question of how niche applications will shape the next wave of scaling solutions.

By moving transaction volume off the main chain, Layer 2s have reduced the number of fees burned, which has slowed the deflationary pressure on the ETH supply.
State channels reduce transaction latency and costs by allowing users to conduct interactions off-chain while maintaining the security of the underlying blockchain.
Investors worry that Layer 2s capture significant profits while contributing relatively little back to the mainnet, potentially weakening the main chain's economic utility.
The Pectra upgrade aims to improve institutional and retail accessibility by increasing blob capacity and introducing account abstraction, allowing users to pay gas fees with stablecoins.
