Ethereum’s delay of the Glamsterdam upgrade on its Hoodi testnet follows a finding that some smart contracts could permanently record operations that were meant to remain retryable. Security firm ChainSecurity said Thursday that developers had postponed the activation scheduled for October 26, 2026, after it identified problems with the upgrade’s gas changes. Key takeaways ChainSecurity found 13 real-world examples of potentially affected contracts. Hoodi node operators should use software that removes the scheduled upgrade. Glamsterdam is already active on Sepolia, with a gas limit near 200 million.
