Reported November 10, 2026. ChainCatcher reported that Ethlabs, which it described as an Ethereum non-profit research and development organization, had published a note on EIP-8037 and EIP-8038 in the Glamsterdam upgrade.
Proposals and status
Both proposals concern adjustments to gas costs and the billing mechanism. Glamsterdam’s stated aim is to raise Ethereum’s per-block gas limit from 60 million to 200 million. In the report, EIP-8037 and EIP-8038 are specification items under review. They are not described as an activated upgrade, a client release, or a change already deployed on a network.
Contracts that may be affected
Ethlabs said gas-cost adjustments may affect contracts and tools that hardcode operation costs. Billing changes may also cause unexpected behavior in some already deployed contracts. The example given: after an internal call reverts, gasleft() returns a remaining-gas figure that increases, which can change how a contract judges whether a call failed because it ran out of gas.
Decision still with ACD
Ethlabs recommended holding off on changes to the upgrade specification, and on setting a Hoodi testnet fork date, until external audit results are published and the related impact is clear. It said the final decision belongs to the Ethereum core developers meeting (ACD).
The Ethereum Foundation had commissioned two external audits, by ChainSecurity and Dedaub, expected to be published before November 16. ChainCatcher also reported that, on the same day, the ACD testing meeting would hold a public Q&A. The ACD execution-layer meeting on November 19 was expected to discuss the audit results and might decide whether to modify the upgrade specification. Those timings are the expectations stated in the November 10 report.
