Ethereum Delays Glamsterdam Rollout as Developers Investigate Contract Risks

Ethereum’s upcoming Glamsterdam upgrade has hit a testing delay after researchers raised concerns that proposed changes could affect how existing smart contracts execute.

The Ethereum Foundation canceled the Hoodi testnet activation scheduled for October 26, 2026. Developers have yet to set a new date, while the timing of a mainnet release remains unconfirmed.

Security Review Delays Hoodi Activation

Ethereum developers had considered December as a potential window for the mainnet launch, but no official schedule has been established. Further progress will depend on resolving the reported issues and completing additional testing.

The delay also pauses Hoodi’s planned gas limit increase to 200 million. Developers must revise the testing timetable before proceeding with the activation and associated changes.

ChainSecurity Flags EIP-8037 Risks

The main concern involves EIP-8037, a proposal designed to change gas accounting for operations that create blockchain state.

ChainSecurity identified scenarios in which smart contracts could have more or less gas available than expected. These differences may disrupt contract error handling and failed operations, potentially producing unintended results.

Developers are examining the findings to understand the potential impact on existing contracts and determine whether the proposal needs modifications before testing can resume.

Glamsterdam Still Part of Ethereum’s Roadmap

The Hoodi delay does not mean Ethereum has scrapped Glamsterdam. The upgrade continues to target improvements to the network’s underlying infrastructure, including enshrined proposer-builder separation and block-level access lists.

Before moving toward a mainnet launch, developers need to resolve the security questions, conduct another round of Hoodi testing and establish a revised deployment schedule.

Ether Holds Below $2,400

Ether traded in a range of approximately $2,370 to $2,415, recording a decline of around 0.5%.

A break above $2,415 could suggest improving near-term momentum. Conversely, falling below $2,370 may increase the risk of additional selling pressure.

For Ethereum developers, the immediate priority remains addressing the smart contract concerns before setting a firm date for Glamsterdam’s rollout.
