Ethereum Developers Flag Contracts at Risk from Glamsterdam Gas Changes

The Ethereum Foundation has issued a warning to developers about potential issues with smart contracts due to upcoming gas changes in the Glamsterdam upgrade. The changes, which include EIP-8037 and EIP-8038, are designed to adjust state-creation costs and access prices across the execution layer.

According to the Ethereum Foundation, most contracts will remain unaffected by the changes, but a small group may break or degrade without updates. The affected contracts rely on fixed gas stipends, hardcoded call limits, or logic based on gasleft().

The warning extends beyond smart contracts, as wallets and gas estimators also need to be updated to account for the revised cost rules. Software using cached constants could underestimate the gas needed for a transaction and cause it to fail.
