Overview
What is Ethereum Layer 2 Networks Hit Record Activity in July 2026?
July 2026 marked a historic inflection point for Ethereum's Layer 2 ecosystem. For the first time, the combined daily transaction volume across Layer 2 networks β including Base, Arbitrum, Optimism, zkSync Era, and Starknet β exceeded Ethereum mainnet throughput by a factor of more than 12 to 1. This milestone, widely anticipated by the Ethereum developer community, validated the long-running bet that L2 scaling would drive the next phase of Ethereum adoption rather than a wholesale migration to competing Layer 1 chains.
Base, Coinbase's Layer 2 network built on the OP Stack, was the standout performer of the month. Daily active addresses on Base crossed 4.2 million β surpassing Ethereum mainnet's 1.1 million β as Coinbase's retail distribution network continued to funnel millions of users into the on-chain ecosystem. The network's total value locked (TVL) grew to over $24 billion, cementing it as the second-largest L2 by TVL behind Arbitrum. Base's success has been driven in part by its deep integration with Coinbase's centralised exchange, allowing users to move funds on-chain with a single tap β dramatically reducing the friction that historically prevented retail users from participating in DeFi.
Arbitrum maintained its position as the largest Ethereum L2 by TVL at $31 billion, with its decentralised finance ecosystem continuing to attract sophisticated users. The Arbitrum DAO β one of the most active decentralised governance organisations in crypto β approved several high-profile protocol upgrades during July, including a new fee rebate programme for high-volume market makers that further improved liquidity depth on native decentralised exchanges.
The technical catalyst for July's surge was the full activation of EIP-7691, which doubled the blob count per block following the Pectra hard fork earlier in the year. This increase in data availability capacity directly reduced L2 transaction costs. Average transaction fees on Base and Arbitrum fell to approximately $0.002β$0.004 per transaction in July β costs so low they are effectively imperceptible to end users and have unlocked entirely new categories of micro-transaction and gaming use cases.
DeFi activity on L2 networks reached new highs. The combined daily DEX trading volume across all major L2s exceeded $18 billion on peak days in July, representing a 340% year-over-year increase. Lending protocols including Aave and Compound reported record loan originations on L2 deployments as users discovered that the same DeFi primitives available on mainnet could now be accessed at a fraction of the cost.
NFT and gaming activity on L2 networks also hit new records. Base-native gaming protocols attracted over 800,000 daily players during July, driven by on-chain games that leverage the network's near-zero transaction costs to enable true in-game asset ownership. This activity drove significant ETH burn through transaction fees even on L2, contributing to ongoing deflationary pressure on the Ethereum supply.
From a price perspective, ETH rose approximately 19% during July, outperforming both Bitcoin and the broader crypto market. Analysts attributed the outperformance to a combination of factors: the positive L2 activity data, continued ETH staking demand (approximately 28% of the total supply is now staked), and increasing institutional interest in ETH as a yield-generating asset via staking products offered through regulated custodians and ETF structures.
For crypto traders and automated strategies, the L2 explosion created new opportunities in L2-native governance tokens. ARB (Arbitrum), OP (Optimism), and ZK (zkSync) all experienced significant price appreciation during July as their respective networks posted record metrics. Cross-chain arbitrage strategies that exploit price discrepancies across L2 ecosystems also became increasingly viable as liquidity on these networks deepened.
