Ethereum layer‑2 networks like Arbitrum and Optimism see rising adoption in July 2026, driven by DeFi, gaming and AI demand for lower fees and faster

A surge in Ethereum congestion has pushed users toward layer‑2 networks, with ten projects collectively drawing strong DeFi, gaming, AI and tokenized‑asset activity as of July 2026 [1].

| At a glance | |
|---|---|
| Top projects | 10 |
| Main use cases | DeFi, gaming, AI, tokenized assets |
| Fee reduction | Up to 95 % vs. Ethereum mainnet |
| Growth catalyst | High Ethereum fees and slow transaction speeds |

## Why layer‑2 adoption is accelerating  
Ethereum’s base layer continues to lead the blockchain market, but “high fees and slow transaction speeds… create challenges during busy periods” [1]. Layer‑2 solutions process transactions off‑chain before anchoring final data to Ethereum, cutting fees dramatically and boosting throughput. This cost advantage is attracting a broad set of applications—from decentralized exchanges on Arbitrum to NFT games on Immutable—fueling a “steady growth in decentralized finance, gaming, artificial intelligence, and tokenized real‑world assets” [1].

## The leading networks and their niches  
Arbitrum tops the list, anchored by a “large decentralized finance ecosystem and strong liquidity” and expanding into layer‑3 via Arbitrum Orbit [1]. Optimism distinguishes itself with the Superchain vision, enabling multiple OP‑Stack chains such as Coinbase’s Base and offering revenue sharing across connected networks [1]. Zero‑knowledge rollups like Starknet and zkSync focus on cryptographic proofs for security and speed, drawing DeFi, gaming and payment projects [1]. Polygon pivots toward an ecosystem of connected zero‑knowledge chains under its AggLayer plan, appealing to enterprises and tokenized‑asset issuers [1]. Emerging players—Mantle, Immutable, Metis, Loopring and Fuel—target niche markets such as institutional DeFi, gas‑free gaming, AI infrastructure, secure payments and modular execution layers [1].

## Market context and outlook  
The 21shares mid‑year report notes that “institutional capital… remains resilient,” with global crypto ETP assets at $140 billion despite a 15 % YTD dip [2]. While the report does not quantify layer‑2 flows directly, it highlights “the rapid scaling of emerging high‑quality projects” as a driver of institutional interest [2]. This suggests that layer‑2 adoption is not only a technical response to congestion but also a factor in broader capital allocation trends.

## What to watch
- **Ethereum fee levels** – A sustained rise above $30 per gas unit could push more users to layer‑2 solutions.  
- **Arbitrum Orbit launch** – Track the first mainnet deployment date for layer‑3 capabilities.  
- **Regulatory updates** – Monitor any EU or US guidance on rollup security that could affect adoption of zero‑knowledge solutions.

Layer‑2 scaling is becoming a structural pillar of the Ethereum ecosystem, reducing costs and unlocking new use cases. The open question is whether these networks can maintain their growth momentum as Ethereum upgrades (e.g., sharding) aim to address the same scalability challenges.
