Ethereum Foundation warns that wallets, indexers, and gas calculators may break due to gas calculation model changes in the upcoming Glamsterdam upgrade.
Tech & Launches ·
The Ethereum Foundation's Protocol DevOps team has cautioned that wallets, indexers, and gas estimators relying on hardcoded maximum gas limits face breakage from gas-model modifications under the Glamsterdam upgrade. The EF warned that any software assuming 21,000 gas covers all ETH transfers or operating with a single gas dimension must be revised before the upgrade rolls out across testnets and mainnet.
The upcoming upgrade introduces EIP-8037, which establishes a separate state-gas component for operations generating new state. Under this model, transferring ETH to an existing address remains 21,000 gas, but sending to a new address incurs an additional state-gas cost. Glamsterdam also encompasses enshrined proposer-builder separation, block-level access lists, and expanded limits for contract and initialization-code sizes.
Developers have been directed to test systems on Plataberget, a public testnet launched in August intended to run for several months. Glamsterdam is slated to activate on Plataberget before deploying to the Sepolia and Hoodi testnets. The scope and timeline of any broader rollout to other testing environments remains unspecified.
