Ethereum layer-2 networks want “responsive pricing” to scale to billions of customers and cut back the price 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 price market by modifying the fuel price restrict and launched a function that burns a part of the transaction charges, eradicating them completely from circulation.
Felten stated gas-price swings are nonetheless the primary mechanism for safeguarding networks from being overrun during times of heavy demand, regardless that that produces the type of price volatility mainstream customers are likely to reject.
“[With responsive pricing], you’ll be able to see extra visitors at decrease fuel costs with out overrunning the infrastructure.”
Risky fuel costs have lengthy been a barrier to mass adoption, significantly for customers accustomed to mounted or predictable transaction prices in conventional monetary techniques.
The difficulty issues as a result of Ethereum’s scaling story is now 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 actually 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 fuel 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 response to information from L2beat. L2s are securing over $39.7 billion in cumulative TVL, up 4.6% over the previous yr.
Whereas responsive pricing could also be extra scalable and extra clear about underlying prices, its greatest draw back is decrease predictability than EIP-1559, in response to 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 effectively. Responsive pricing leans into the second,” he informed Cointelegraph.

Responsive pricing is a step ahead, however the fuel mannequin wants changing
Jerome de Tychey, president of Ethereum France and EthCC, informed Cointelegraph that responsive pricing might enhance person expertise by making charges extra intently replicate precise community demand.
Cyprien Grau, venture lead at gasless Ethereum L2 Standing Community, agreed, calling the brand new pricing mannequin a “actual enchancment in price accuracy.” Nevertheless, the mannequin nonetheless depends on a “price market,” which means that customers should still face variable prices and fuel spikes throughout congestion, he informed Cointelegraph.
“It doesn’t resolve the structural downside: L2 fuel 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 fuel mannequin,” however stated the fuel mannequin wants changing. “L2s that scale to billions of customers would be the ones the place customers by no means take into consideration fuel in any respect, and the place networks’ economics do not rely on charging them for it,” he added.
The price mannequin debate comes as elements of the Ethereum ecosystem are already rethinking the unique rollup-centric scaling thesis. In February, Vitalik Buterin argued that some layer-2 assumptions now 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 strategy, as these networks have siphoned vital financial worth from the mainnet.
