Ethereum's Speed Boost Plan Risks Breaking Millions of Smart Contracts

Ethereum's upcoming plan to triple its network speed could break millions of existing smart contracts silently, according to a recent report. The Ethereum Foundation has proposed two new EIPs (Enhancement Proposals) that will increase gas costs for state creation and access to existing state. These changes aim to support roughly three times more base throughput by aligning gas charges with the network resources each operation consumes.

The proposals, EIP-8037 and EIP-8038, are scheduled for the Glamsterdam schedule and have formal Review status. Ethereum's official roadmap plans the upgrade for the fourth quarter of 2026. The testing window before the candidate parameters and deployment schedule harden is limited, leaving builders with a short time to test their contracts and tools against the new schedule.

The EIPs will increase gas costs for state creation and access to existing state, which could break millions of existing smart contracts. According to the report, wallets, RPC providers, indexers, node tooling, and gas estimators must incorporate the new rules, while frontends and bundlers need to stop relying on cached constants or limits calibrated to the old schedule.

Developers carry the immediate burden of resimulating transactions, reviewing fixed stipends and internal call limits, and testing affected paths against the candidate schedule. Regular users can keep familiar workflows if wallets and infrastructure update correctly.
