Two rival proposals filed on Sunday aim to keep older Ethereum contracts working after the Glamsterdam upgrade, CoinDesk reported. The concern is that Glamsterdam would raise gas costs for creating and storing data under EIP-8037 and EIP-8038. Under EIP-8037, the base cost of creating a contract would rise from 32,000 gas to 183,600. Applications that pay a fixed amount of gas when calling other contracts and cannot be updated could then fail.
A second Glamsterdam test on a practice network, planned for October 26, was postponed after security researchers raised concerns. Researcher pcaversaccio said on X the upgrade should not ship in its current form. Developer banteg pointed to a list of about 200,000 affected contracts and said the analysis could miss many more.
Leo Glisic’s EIP-8488 would split Ethereum’s instruction set in two: existing contracts keep the legacy gas schedule, while new contracts must use V2 opcodes that follow the new pricing. Giulio Rebuffo’s draft, filed as GitHub pull request 12637, would charge everyone the new prices but run two gas meters per transaction, one tracking execution under the old rules and one for billing. Rebuffo acknowledged that no execution-client implementation or consensus tests exist for the design.
Neither proposal has a target date. The next private test was estimated for November 16 to 20 at the earliest, and was planned before either draft existed.
