Developers checking how their contracts handle gas should watch two proposals for Ethereum’s planned Glamsterdam upgrade: EIP-8037 and EIP-8038. In a ChainCatcher report originally published on November 10, 2026, at 17:48:41 UTC+08:00, Ethereum nonprofit research organization Ethlabs said the proposals’ changes to gas costs and accounting could affect some deployed smart contracts.
Glamsterdam aims to raise Ethereum’s per-block gas limit from 60 million to 200 million. According to Ethlabs, changes to gas costs could affect contracts and tools with hard-coded operation costs. Accounting changes could also produce unexpected behavior in some deployed contracts: after an internal call reverts, gasleft() might report more gas remaining, potentially affecting how a contract determines whether the call failed because it ran out of gas.
Ethlabs recommended waiting for external audit results and a clearer assessment of the effects before changing the upgrade specification or setting a fork date for the Hoodi testnet. The Ethereum Foundation had commissioned external audits from ChainSecurity and Dedaub, which were expected to be released by November 16. A public Q&A was scheduled for an All Core Developers (ACD) testing meeting that day. The November 19 ACD execution-layer meeting was expected to discuss the audits and could decide whether to change the upgrade specification. Ethlabs said the final decision rested with ACD.
