Ethereum Glamsterdam Upgrade Could Break Wallets and Gas Estimators

The Ethereum Foundation has issued a warning that the upcoming Glamsterdam upgrade could break wallets, indexers, and gas estimators that rely on fixed gas assumptions.

EIP-8037 will introduce a separate state-gas dimension for operations that create new state, which will be metered at a fixed cost per state byte and charged at runtime.

This change means that sending ETH to an account that already exists will still cost 21,000 gas, but transfers to new accounts will incur an additional state-gas charge tied to creating the new account.

The Protocol DevOps team has urged developers to test their software on the Platåberget testnet before Glamsterdam moves to Sepolia and Hoodi, as any tool relying on a hardcoded maximum gas limit 'will break.'
