Ethereum Delays Part of Glamsterdam Over Smart Contract Risks

Ethereum has postponed part of the Glamsterdam upgrade process after developers found smart contract assumptions that could break under EIP-8037 and EIP-8038.

Ethereum has delayed part of its Glamsterdam upgrade process after identifying smart contract assumptions that could fail under two proposed changes, EIP-8037 and EIP-8038.

The concern is about security. Existing contracts are written with certain expectations about how the network behaves. If a protocol change alters those expectations, code that works today could behave in unintended ways once the upgrade goes live. Developers decided that the risk warranted slowing down the rollout rather than pushing ahead.

Why the delay matters

Hardforks change the rules of the network for every participant, and they cannot easily be reversed once activated. Contracts holding user funds are especially sensitive, because a broken assumption can open the door to bugs or exploits. Postponing the affected part of the process gives teams more time to assess the impact and, if needed, adjust the proposals.

For users, the practical effect is limited for now: nothing changes on the live network, and the delay is about the schedule of the upgrade rather than a flaw in current operations. Developers who maintain contracts may need to review their code against the proposed changes as the discussion continues.

What comes next

The material available does not specify a new timeline for Glamsterdam. Further details on how EIP-8037 and EIP-8038 may be revised, or how affected contracts will be handled, are expected to emerge from continued developer discussions.
