Ethereum postpones Glamsterdam upgrade after spotting smart contract risks

Ethereum developers have pushed back the Glamsterdam upgrade on the Hoodi testnet, originally set for October 26. The move follows warnings that certain changes could break how existing smart contracts handle errors.

A report by ChainSecurity, released on October 13, flagged risks tied to EIP-8037 and EIP-8038 running together. The proposals alter gas calculations and could produce unexpected behavior when contracts run out of gas during calls.

Developers chose to extend the review period rather than proceed with the current plan. No new test date has been set yet.

The upgrade itself remains on the roadmap, but teams want stronger assurances on compatibility before deployment.
