Writing one new storage slot on Ethereum costs 22,100 gas today. Under the schedule bundled into Glamsterdam it will cost 110,020, and the Ethereum Foundation’s protocol team has opened a public repository, last updated on 6 November 2026, asking auditors to hunt that difference through every client contract they have reviewed. The repository lists eight invariants that EIP-8037 and EIP-8038 break, each with the price that changes, the code pattern that fails, and a suggested fix.
