Ethereum delays Glamsterdam test after security devs flag risk to existing contracts

Ethereum developers have called off Monday's Glamsterdam upgrade on the Hoodi test network after security researchers identified a problem that could change how existing smart contracts handle failed transactions, potentially allowing errors to become permanent.

The upgrade was due to activate on Oct. 26 at 17:42:48 UTC. Developers postponed it during Thursday's All Core Devs Execution meeting to investigate how a proposed change to Ethereum's gas accounting interacts with contracts already running on the main network.

The concern centers on EIP-8037, which changes how Ethereum charges for creating new records in its database. The proposal is intended to limit the growth of that database as Ethereum increases the number of transactions its network can process.

Security firm ChainSecurity published an analysis on Oct. 13 showing that the change, combined with EIP-8038, could alter how contracts respond when another contract they call runs out of gas, or the fees used to pay the network’s operators.

Some contracts are designed to catch a failed operation and continue processing. They may record that an attempt failed, disable further attempts or move to another step. Developers sometimes rely on the remaining gas being too low for those actions to finish, causing the entire transaction to reverse instead.

Glamsterdam changes that calculation. Under the proposed rules, gas used to create certain records can be restored when those changes are undone. That can leave enough gas for a contract to complete a failure-handling operation that previously would have reversed.
