# Ethereum Foundation Has Four Reports of Contracts That Could Break Under Glamsterdam By Simon Yoon Canonical URL: https://www.tokenpost.com/news/technology/55928 Published: 2026-11-12T21:36:40.000Z Updated: 2026-11-12T21:36:40.000Z Section: Technology > Former Ethereum core developer Greg Markou said proposal volume has grown with artificial intelligence tools and estimated about 10 proposals arrive each day. The Ethereum Foundation said Nov. 9 it had four reports of deployed contracts that could break under Glamsterdam’s proposed gas changes, as developers keep the upgrade on hold for further review. EIP-8037 and EIP-8038 would change gas charges for some operations and stored data. Ethereum charges gas to cover computation and data storage. Developers called off a planned Oct. 26 launch on the Hoodi testnet after [putting the Glamsterdam process on hold over eight gas invariants](). Greg Markou, a former Ethereum core developer, said Nov. 11 that developers “bundle 30 EIPs into a giant hard fork,” and that “one of them’s gonna break.” He estimated that about 10 proposals arrive each day and said the flow had grown with AI tools. Markou urged application teams to test against the coming fork and report any problems. The recommendation echoes [his earlier warning that testnets can miss failures in live applications](). The Ethereum Foundation said a call scheduled for Thursday, Nov. 19, would discuss audit findings, with no decision set in advance. ## Links in this article - [putting the Glamsterdam process on hold over eight gas invariants](https://www.tokenpost.com/news/technology/51334) - [his earlier warning that testnets can miss failures in live applications](https://www.tokenpost.com/news/technology/55194)
