Ethereum developers flag contracts at risk from gas changes

Ethereum developers warned on Aug. 24 that planned gas changes in the Glamsterdam upgrade could disrupt a small group of Layer 1 smart contracts. Summary Ethereum developers warned Glamsterdam gas repricing could break a small group of Layer 1 contracts. EIP-8037 raises state-creation costs, while EIP-8038 reprices storage and account access across Ethereum’s execution layer. Most flagged failures can be resolved by increasing transaction gas limits, according to Ethereum developers. Contracts using 2,300-gas stipends, fixed call limits or gasleft logic face the greatest compatibility risks. Developers can test contracts immediately on Platåberget before public testnet and eventual mainnet deployment begins. The Ethereum Foundation urged developers to test contracts and update fixed gas assumptions before mainnet activation. The warning concerns EIP-8037 and EIP-8038, which are scheduled for inclusion in Glamsterdam. Developers said most contracts remained unaffected during transaction replays, while many flagged cases could be corrected by raising their gas limits.
