Ethereum layer-2 networks want “responsive pricing” to scale to billions of customers and scale back the charge swings that also accompany congestion, Offchain Labs co-founder Edward Felten stated throughout a keynote at EthCC 2026.
Ethereum’s EIP-1559 improve launched in August 2021, as a part of the London arduous fork. It reformed the Ethereum charge market by modifying the gasoline charge restrict and launched a characteristic that burns a part of the transaction charges, eradicating them completely from circulation.
Felten stated gas-price swings are nonetheless the principle mechanism for shielding networks from being overrun during times of heavy demand, regardless that that produces the type of charge volatility mainstream customers are likely to reject.
“[With responsive pricing], you may see extra visitors at decrease gasoline costs with out overrunning the infrastructure.”
Risky gasoline costs have lengthy been a barrier to mass adoption, notably for customers accustomed to fastened or predictable transaction prices in conventional monetary techniques.
The difficulty issues as a result of Ethereum’s scaling story is not nearly including extra throughput. It’s more and more about whether or not layer-2 networks could make transaction prices predictable sufficient for mainstream-style apps whereas nonetheless pricing congestion truthfully sufficient to guard infrastructure beneath heavy demand. Arbitrum’s dynamic pricing rollout is now one of many first dwell exams of that tradeoff.
Arbitrum One the primary L2 to undertake responsive pricing
Arbitrum One adopted dynamic pricing in January. It described the mannequin as an “Arbitrum platform course to make charges extra predictable beneath demand by aligning costs with actual community bottlenecks.”

Felten shared a number of charts exhibiting how Arbitrum gasoline charges remained decrease throughout peak community volumes than charges on the Base community and different L2s that depend on EIP-1559.
Arbitrum One is the most important L2 with $15.2 billion in TVL, whereas Coinbase’s Base Chain is second with $10.9 billion, in keeping with information from L2beat. L2s are securing over $39.7 billion in cumulative TVL, up 4.6% over the previous 12 months.
Whereas responsive pricing could also be extra scalable and extra clear about underlying prices, its largest draw back is decrease predictability than EIP-1559, in keeping with Julian Kors, a senior developer and founding father of execution workspace startup Pulsar Areas.
The talk will not be about one mannequin being higher, however whether or not networks optimise for “predictability and mechanism design purity or for effectivity and real-time price alignment. EIP-1559 does the primary very nicely. Responsive pricing leans into the second,” he advised Cointelegraph.

Responsive pricing is a step ahead, however the gasoline mannequin wants changing
Jerome de Tychey, president of Ethereum France and EthCC, advised Cointelegraph that responsive pricing might enhance person expertise by making charges extra intently mirror precise community demand.
Cyprien Grau, challenge lead at gasless Ethereum L2 Standing Community, agreed, calling the brand new pricing mannequin a “actual enchancment in charge accuracy.” Nevertheless, the mannequin nonetheless depends on a “charge market,” which means that customers should face variable prices and gasoline spikes throughout congestion, he advised Cointelegraph.
“It doesn’t remedy the structural downside: L2 gasoline charges pattern towards zero as scaling on L1 and L2s improves and competitors intensifies. Responsive pricing makes the decline smoother, however you’re nonetheless constructing a income mannequin on a depreciating asset.”
Grau added that responsive pricing is the “most superior model of the gasoline mannequin,” however stated the gasoline mannequin wants changing. “L2s that scale to billions of customers would be the ones the place customers by no means take into consideration gasoline in any respect, and the place networks’ economics do not rely upon charging them for it,” he added.
The charge mannequin debate comes as components of the Ethereum ecosystem are already rethinking the unique rollup-centric scaling thesis. In February, Vitalik Buterin argued that some layer-2 assumptions not held and that future scaling ought to rely extra closely on the mainnet and native rollups.
L2 networks have been created to scale Ethereum and offload a part of the transaction load from the mainnet. Nevertheless, Ethereum is now reconsidering its L2-centric method, as these networks have siphoned vital financial worth from the mainnet.
