Ethereum Developers Pause Glamsterdam Upgrade on Hoodi Testnet Over Smart Contract Issues

Concerns Over Smart Contract Invariants

Concerns over eight smart contract invariants associated with Glamsterdam's proposals, EIP-8037 and EIP-8038, have prompted Ethereum developers to postpone the implementation of the Glamsterdam upgrade on the Hoodi testnet. The Ethereum Foundation made this announcement in a blog post on Friday, explaining that certain existing Ethereum projects depend on fixed gas cost assumptions that could potentially be invalidated by these new EIPs.

Impact of ChainSecurity Report

The decision to delay follows an alarming report from ChainSecurity, a firm dedicated to smart contract auditing, which highlighted that the proposed changes might disrupt contracts that rely on stable gas price assumptions, particularly in scenarios where external calls fail. By stalling the Hoodi fork’s progress, developers can take the necessary time to investigate these issues further and make critical modifications if needed before the Glamsterdam upgrade is deployed on the mainnet.

Glamsterdam Upgrade Overview

Notably, the Glamsterdam upgrade had already been activated on the Sepolia testnet as of October 6, marking it as a significant step in the evolution of Ethereum’s scaling roadmap. This upgrade seeks to introduce advancements such as:

• Enshrined proposer-builder separation
• Block-level access lists
• Revised gas pricing intended to more accurately represent execution costs

The Hoodi testnet will remain in limbo pending the resolution of these pressing concerns, underscoring the ongoing attention to security and functionality within Ethereum's development efforts, as highlighted by the Foundation’s communication.
