Ethereum Layer 2 Transactions Break 100 Million Daily as Arbitrum and Base Lead
Ethereum’s Layer 2 networks have passed 100 million daily transactions for the first time. Arbitrum and Base are leading the charge — here’s what it means.
Ethereum’s Layer 2 ecosystem hit a milestone in May 2026: combined daily transaction volume across all major Layer 2 networks exceeded 100 million for the first time. Arbitrum and Base — Coinbase’s Ethereum Layer 2 — account for the majority of that activity, with smaller contributions from Optimism, zkSync, and Polygon’s zkEVM.
The figure marks a transformation in how Ethereum is used. Three years ago, the network processed around 1 million transactions per day on its main chain, constrained by high gas fees and limited throughput. Today, the Layer 2 ecosystem multiplies that capacity dramatically while keeping the security guarantees of Ethereum’s base layer.
What Is a Layer 2 Network?
Layer 2 networks process transactions off Ethereum’s main chain but periodically submit cryptographic proofs of those transactions back to Ethereum for final settlement. This approach dramatically increases throughput and reduces costs for users while relying on Ethereum’s security model for trust.
There are two main types of Layer 2 technology currently in production. Optimistic rollups — used by Arbitrum and Optimism — assume transactions are valid by default and use a fraud-proof system to catch errors. Zero-knowledge rollups — used by zkSync and Polygon’s zkEVM — generate cryptographic proofs that every transaction is valid, which is more computationally intensive but faster to finalise.
Why Arbitrum and Base Are Winning
Arbitrum has led the Layer 2 market for most of the past two years. Its ecosystem of decentralised applications — particularly in DeFi, gaming, and NFTs — is the most mature of any Layer 2. The Arbitrum DAO, which governs the network, has been active in distributing ARB token grants to attract new projects.
Base has grown remarkably quickly since its launch in 2023. Backed by Coinbase — one of the largest crypto exchanges in the world — Base benefits from distribution through Coinbase’s retail user base. The integration of Base with Coinbase’s wallet and trading products has funnelled millions of users onto the network.
Transaction fees on both networks are typically well below £0.01, compared to several pounds or more during periods of congestion on Ethereum’s main chain. At those costs, applications that were economically unviable on Layer 1 — micropayments, gaming transactions, social media tipping — become practical.
The Impact on ETH Price and Value Accrual
A common concern among Ethereum investors is whether Layer 2 growth benefits ETH holders or cannibalises value by reducing main-chain activity and thus reducing the fees burned via Ethereum’s EIP-1559 mechanism.
The evidence in 2026 suggests the relationship is more nuanced. Layer 2 networks pay fees to Ethereum for data availability — the cost of submitting transaction data to the main chain. As Layer 2 activity grows, these fees provide a new revenue stream for Ethereum validators, offsetting some of the reduction in direct main-chain transaction fees.
The Dencun upgrade in March 2024, which introduced proto-danksharding (EIP-4844), significantly reduced the cost for Layer 2 networks to post data to Ethereum. This has enabled the fee growth on Layer 2 without requiring those networks to pay prohibitive amounts to the main chain.
What 100 Million Daily Transactions Mean for DeFi
At 100 million transactions per day, Ethereum’s Layer 2 ecosystem now processes roughly the same volume as Visa’s global payment network. The comparison is imperfect — crypto transactions vary enormously in size and complexity — but it illustrates the scale at which the technology now operates.
For decentralised finance, the throughput improvement is enabling more sophisticated applications. Perpetual futures trading protocols, on-chain options markets, and real-time gaming economies all require high transaction volumes and low latency. Layer 2 networks are making these applications viable in ways that were impossible on Ethereum’s main chain alone.
What UK Crypto Users Need to Know
For UK users, Layer 2 networks are accessible through mainstream wallets like MetaMask, Coinbase Wallet, and Rainbow. Bridging funds from Ethereum’s main chain to a Layer 2 involves a transaction on Layer 1, which still incurs standard Ethereum gas fees. Once on a Layer 2, subsequent transactions cost a fraction of a penny.
HMRC guidance on cryptocurrency taxation applies to Layer 2 transactions in the same way as Layer 1 transactions. Swaps, sales, and conversions are taxable events regardless of which network they occur on. UK users should maintain records of their Layer 2 activity for tax reporting purposes.
FCA-registered exchanges including Coinbase and Kraken support direct deposits and withdrawals on some Layer 2 networks, simplifying access for UK users who do not want to manage bridge transactions manually.
