Ethereum Delays Hoodi Testnet Fork Over Smart Contract Gas Risks

Ethereum developers halted the Glamsterdam fork on the Hoodi testnet to address security concerns regarding gas-related smart contract invariants, though the broader scaling roadmap remains on track.

Ethereum core developers have halted the Glamsterdam fork on the Hoodi testnet after an Oct. 13 ChainSecurity report flagged that EIP-8037 and EIP-8038 could break smart contracts relying on fixed gas assumptions. The delay pushes back a key step toward mainnet deployment, a mild negative for sentiment on ETH in the coming days to weeks. The issue is a testnet-only postponement, so the broader layer-1 scaling roadmap remains intact, limiting the downside.

Catalysts
  • ▼ Hoodi testnet fork postponed until eight smart contract invariant concerns are resolved
  • ▼ Oct. 13 ChainSecurity report found EIP-8037 and EIP-8038 could break contracts relying on fixed gas-related assumptions
Risk Factors
  • ▲ Glamsterdam already went live on the Sepolia testnet on Oct. 6, so upgrade progress continues elsewhere
  • ▲ Delay is precautionary on a testnet; mainnet deployment timeline is not yet formally changed
▼ Show FAQ (2) ▲ Hide FAQ
Why was the Ethereum upgrade delayed?

Developers found that two planned changes, EIP-8037 and EIP-8038, would alter gas costs in ways that could break smart contracts relying on fixed gas assumptions, so the Hoodi testnet fork is paused until those concerns are fixed.

Does this stop the Glamsterdam upgrade entirely?

No. The upgrade already ran on the Sepolia testnet on Oct. 6, and the delay only pauses the Hoodi testnet fork while the security issues are investigated before mainnet.

🎯 Key Takeaways

  • ChainSecurity report flagged potential smart contract breakage due to EIP-8037 and EIP-8038 gas cost changes.
  • The Glamsterdam upgrade remains active on the Sepolia testnet, limiting the impact of the Hoodi delay.
  • Developers are prioritizing the resolution of eight identified smart contract invariants before proceeding with the Hoodi fork.

📝 Executive Summary

Ethereum core developers have paused the Glamsterdam upgrade on the Hoodi testnet following an Oct. 13 ChainSecurity report. The audit identified that EIP-8037 and EIP-8038 could disrupt smart contracts that rely on fixed gas assumptions, prompting a precautionary delay to ensure network stability before mainnet deployment.
