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 consequence of congestion.
Ethereum’s EIP-1559 improve was launched in August 2021 as a part of the London onerous fork. We have now reformed the Ethereum charges market by altering fuel price limits and introducing the flexibility 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 in periods of excessive demand, although they trigger the type of price fluctuations that mainstream customers are likely to reject.
“[Responsive pricing]permits us to see extra site 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 fastened or predictable transaction prices in conventional monetary programs.
This challenge is vital as a result of scaling Ethereum is not nearly including throughput. It’s more and more vital that Layer 2 networks can value congestion actually sufficient to guard the infrastructure beneath 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 path 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 response to L2beat information, Arbitrum One is the biggest 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 12 months, securing greater than $39.7 billion in cumulative TVL.
Responsive pricing could also be extra scalable and have extra underlying value transparency, however its largest downside is that it is much less predictable than EIP-1559, mentioned Julian Kors, senior developer and founding father of execution workspace startup Pulsar Areas.
The talk shouldn’t be about which mannequin is best, however slightly whether or not the community optimizes for “predictability and purity of mechanism design, or effectivity and real-time value adjustment. EIP-1559 does the previous very effectively. Responsive pricing leans in direction of the latter,” he informed Cointelegraph.

Responsive pricing is a step ahead, however fuel fashions must be changed
Jérôme de Tichet, president of Ethereum France and EthCC, informed Cointelegraph that responsive pricing may enhance the person expertise by permitting charges to extra precisely mirror 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.” Nonetheless, the mannequin nonetheless depends on a “price market,” so customers may nonetheless face variable charges and fuel spikes throughout busy intervals, he informed Cointelegraph.
“The structural downside persists. As L1 and L2 scaling improves and competitors will increase, L2 fuel costs will development towards zero. With responsive pricing, the decline shall be 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 rely upon billing,” he added.
The pricing mannequin dialogue comes as elements of the Ethereum ecosystem are already rethinking their unique rollup-centric scaling concept. Vitalik Buterin argued in February that among the assumptions of Layer 2 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 among the transaction load from the mainnet. Nonetheless, Ethereum is at the moment rethinking its L2-centric strategy, as these networks are siphoning vital financial worth from the mainnet.
