Ethereum Layer-2 networks require "responsive pricing" to reduce fee volatility and scale to billions of users, Offchain Labs co-founder Edward Felten said at the EthCC 2026 conference. The statement comes as Arbitrum One, the largest L2 with $15.2 billion in total value locked (TVL), tests the new dynamic pricing model it adopted in January.

"With responsive pricing, you can see more traffic at lower gas prices without overrunning the infrastructure," Felten said during his keynote. He presented data showing Arbitrum's gas fees remained consistently lower during peak congestion than those on Coinbase's Base network, which uses the traditional EIP-1559 fee mechanism.

The move positions Arbitrum against other major L2s in the ongoing debate over scaling solutions. The total TVL secured by L2s now exceeds $39.7 billion, a 4.6 percent increase over the past year, according to data from L2beat. Arbitrum One's primary competitor, Base, holds the second-largest share with $10.9 billion in TVL.

The core issue is whether L2s can provide predictable, low-cost transactions for mainstream applications while still protecting their networks from being overwhelmed by demand. While Arbitrum's model appears to lower peak fees, its long-term viability and adoption by other networks remain key questions for the ecosystem's growth.

A New Approach to L2 Fees

Ethereum's EIP-1559 upgrade, launched in 2021, was designed to make transaction fees more predictable but has resulted in significant fee swings during periods of high network activity. This volatility is a major barrier to mainstream adoption. Arbitrum's responsive pricing aims to align fees more closely with the real-time cost of network resources, making them more stable under pressure.

However, the new model has its critics. Julian Kors, a senior developer at Pulsar Spaces, noted that the trade-off is between "predictability and mechanism design purity or for efficiency and real-time cost alignment." He suggests that while responsive pricing leans into efficiency, it may offer less predictability than EIP-1559.

The Future of L2 Sustainability

Cyprien Grau, project lead at Status Network, called the model a "real improvement in fee accuracy" but argued it doesn't fix the fundamental problem. "It doesn’t solve the structural problem: L2 gas fees trend toward zero as scaling on L1 and L2s improves and competition intensifies," Grau told Cointelegraph. He believes the future lies in models where users "never think about gas at all."

This debate over fee mechanisms comes as Ethereum itself reconsiders its L2-centric scaling roadmap. The new pricing model from Arbitrum is a significant step, but it is part of a much larger and evolving strategy for scaling the Ethereum network to a global user base.
