Ethereum delays Glamsterdam Hoodi fork after ChainSecurity flags gas flaws

Ethereum developers have postponed the Glamsterdam upgrade on the Hoodi testnet after auditor ChainSecurity found gas changes that could let some smart contracts record failed operations permanently.

Why it matters: The delay holds back a major Ethereum upgrade that changes how the network charges for stored data, and it leaves affected projects checking whether their contracts behave differently.

Key points

  • ChainSecurity says it has found 13 real-world examples of contracts affected and is contacting the projects involved.
  • The Hoodi activation had been due on Monday; node operators were told to revert to older software or wait for a client release that cancels it.
  • Glamsterdam went live on Sepolia on 6 October with a gas limit of nearly 200 million, against mainnet's 60 million.

Ethereum developers have postponed the Glamsterdam upgrade on the Hoodi testnet after ChainSecurity flagged security problems with the fork's gas changes, the auditor said on Thursday. The activation had been due on Monday. The delay follows the Glamsterdam testnet fork being called off, with no new date set for Hoodi.

Under the upgrade, gas can be refilled or returned after a failed call, so a failure path that once reverted can now complete.
