The Ethereum Foundation has published an impact analysis of the gas-cost changes planned for the Glamsterdam upgrade. The review focuses on EIP-8037 and EIP-8038, which change the cost of creating new state and accessing existing state so gas pricing better reflects the actual work performed by the network.
Ethereum teams replayed historical mainnet transactions under the new schedule and grouped the outcomes by practical effect. According to the Foundation, the large majority of transactions execute with no change. Some still succeed with different gas usage, while many cases that run out of gas at their original limit complete successfully when given a higher limit. A much smaller group needs deeper review because the behavior can remain broken even after the limit is raised.
The highest-risk patterns are contracts and tools that depend on fixed gas assumptions. The official analysis calls out fixed stipends, hardcoded gas values in calls, logic that branches on gasleft(), and presigned transactions with fixed limits. Developers can use the published affected-contract search and test changes on the Platåberget network, where the new repricing schedule is already available.
For ordinary users, the Foundation says no special action is required because updated wallets and infrastructure should handle the new rules. Application teams, RPC providers and tooling developers have more work to do: cached gas constants and estimation logic need to be reviewed before Glamsterdam progresses through public testnets and toward mainnet activation.
