Glamsterdam Upgrade Shatters the 21k Gas Myth: New State Fees to Break Wallets and Tools

Developers of Ethereum are cautioning that the next Glamsterdam update would upset wallets, indexers, and gas-estimation tools still expecting every ETH transaction to cost precisely 21,000 gas. EIP-8037 adds a new "state-gas" dimension that raises overall expenses for first-time transfers far above 200,000 gas while leaving transfers to current accounts unchanged at the classic 21k level by adding around 183,600 gas when sending ETH to an address never before present on-chain.

Though it will expose any hardcoded presumptions right away, the adjustment fits into a larger gas-repricing program meant to help to achieve more block capacity. Wallets that automatically set a 21k gas limit will underfund new-account transfers; gas estimators will give incorrect costs; and indexers or explorers depending on one gas dimension risk misreporting consumption and costs.

The public testnet of Platåberget is now live and Ethereum Foundation engineers are exhorting fast testing. To prevent quiet transaction failures once Glamsterdam comes online, teams have to take out hardcoded gas limits, change estimation logic to reflect state creation, and re-test wallet flows for first-time sends.
