The upcoming Glamsterdam upgrade will change the gas model, and some software risks malfunctioning. The Ethereum Foundation (EF) team warned about this on August 17.
According to the developers, wallets, indexers, and fee estimation tools could be at risk. Programmers were advised to test their systems on the public testnet Plataberget.
The EF emphasized tools with a "hard-coded maximum gas limit": such solutions, they stated, will stop working and require an update.
The issue is related to EIP-8037. The proposal adds a separate state-gas dimension for operations that create new state. A regular $ETH transfer to an existing address will keep its cost at 21,000 units, but sending coins to a new address will incur an additional charge.
Developers urged a review of smart contracts that assume the logic that 21,000 units covers any $ETH transfer, as well as code that calculates fees based solely on gas quantity.
According to Forkcast, Plataberget was launched on August 13, 2026. The activation of Glamsterdam on this testnet is scheduled for August 20. Before the mainnet launch, there will be a feedback and client software update phase, estimated to last one month, followed by testing on Sepolia and Hoodi.
Recall that in August, Buterin named quantum resistance and AI as priorities for Ethereum.
