The Ethereum Foundation warned that some wallets, indexers and gas estimation tools could stop working after the planned Glamsterdam upgrade.
Cointelegraph reported on August 18 that the foundation's Protocol DevOps team said tools that treat the gas limit as a fixed value will "break" after the upgrade. It urged developers to update them immediately. The team also recommended using Plataberget, a public testnet expected to operate for several months, as a testing environment.
Upgrade-tracking service Forkcast said Plataberget launched on August 13. The Glamsterdam fork will be deployed to the Ethereum mainnet first on Thursday, followed by the Sepolia and Hoodi testnets.
The central change is a revamp of Ethereum's gas model. Under Ethereum Improvement Proposal 8037, or EIP-8037, operations that create new state will be subject to a separate state-gas dimension. Sending Ether to an existing account will still cost 21,000 gas, but transfers to a new account will incur an additional state-gas charge.
The foundation said software that assumes every Ether transfer costs 21,000 gas, or relies on a single gas dimension to estimate transaction fees, must be reviewed. In addition to the gas-model changes, Glamsterdam includes enshrined proposer-builder separation, block-level access lists, and higher size limits for contracts and init code.
