Offchain Labs co-founder Edward Felten mentioned in his EthCC 2026 keynote that Ethereum's Layer 2 community wants “responsive pricing” to scale to billions of customers and nonetheless cut back value fluctuations as a result of congestion.
Ethereum’s EIP-1559 improve was launched in August 2021 as a part of the London exhausting fork. We’ve reformed the Ethereum charges market by altering fuel price limits and introducing the power to burn a portion of transaction charges and completely take away them from circulation.
Felten mentioned fuel value fluctuations are a key mechanism to guard the community from being overwhelmed during times of excessive demand, despite the fact that they trigger the form of charge fluctuations that mainstream customers are likely to reject.
“[Responsive pricing]permits us to see extra visitors at decrease fuel costs with out overloading our infrastructure.”
The worth of risky gases has lengthy been a barrier to mass adoption, particularly for customers accustomed to mounted or predictable transaction prices in conventional monetary programs.
This problem is essential as a result of scaling Ethereum is now not nearly including throughput. It’s more and more essential that Layer 2 networks can value congestion truthfully sufficient to guard the infrastructure below excessive demand whereas making transaction prices predictable sufficient for mainstream-style apps. Arbitrum's rollout of dynamic pricing is now one of many first stay assessments of that tradeoff.
Arbitrum One is the primary L2 with responsive pricing
Arbitrum One adopted dynamic pricing in January. The journal describes the mannequin as “the route of the Arbitrum platform in making pricing extra predictable in response to demand by adjusting costs to match precise community bottlenecks.”

Felten shared a number of graphs displaying how Arbitrum's fuel costs stay decrease than these of the Base community and different L2s that depend on EIP-1559 throughout peak community volumes.
In accordance with L2beat information, Arbitrum One is the most important L2 with a complete TVL of $15.2 billion, whereas Coinbase’s base chain ranks second with $10.9 billion. L2 has grown 4.6% over the previous yr, securing greater than $39.7 billion in cumulative TVL.
Responsive pricing could also be extra scalable and have extra underlying price transparency, however its greatest disadvantage is that it's much less predictable than EIP-1559, mentioned Julian Kors, senior developer and founding father of execution workspace startup Pulsar Areas.
The controversy shouldn’t be about which mannequin is best, however reasonably whether or not the community optimizes for “predictability and purity of mechanism design, or effectivity and real-time price adjustment. EIP-1559 does the previous very effectively. Responsive pricing leans in the direction of the latter,” he instructed Cointelegraph.

Responsive pricing is a step ahead, however fuel fashions have to be changed
Jérôme de Tichet, president of Ethereum France and EthCC, instructed Cointelegraph that responsive pricing may enhance the person expertise by permitting charges to extra precisely replicate precise community demand.
Cyprian Grau, challenge chief for the Gasless Ethereum L2 Standing Community, agreed, calling the brand new pricing mannequin a “actual enchancment in pricing accuracy.” Nevertheless, the mannequin nonetheless depends on a “price market,” so customers may nonetheless face variable charges and fuel spikes throughout busy durations, he instructed Cointelegraph.
“The structural drawback persists. As L1 and L2 scaling improves and competitors will increase, L2 fuel costs will development in the direction of zero. Responsive pricing will make the decline smoother, however you might be nonetheless constructing a income mannequin primarily based on depreciating property.”
Grau added that responsive pricing is “probably the most superior model of the fuel mannequin,” however mentioned the fuel mannequin must be changed. “As L2 scales to billions of customers, customers won’t ever take into consideration fuel and the economics of the community won’t depend upon billing,” he added.
The pricing mannequin dialogue comes as elements of the Ethereum ecosystem are already rethinking their unique rollup-centric scaling idea. Vitalik Buterin argued in February that a number of the assumptions of Layer 2 now not maintain true and that future scaling might want to rely extra on mainnet and native rollups.
The L2 community was created to scale Ethereum and offload a number of the transaction load from the mainnet. Nevertheless, Ethereum is at present rethinking its L2-centric method, as these networks are siphoning important financial worth from the mainnet.
