The Ethereum ecosystem is on the verge of one of the most significant changes to its gas model in recent years. The Glamsterdam upgrade, which is already being actively tested, brings not only optimization but also serious risks to the compatibility of existing software. My analysis has brought to light warnings from the core development team about potential failures in critical tools.
During the analysis of the technical documentation, it became clear that crypto wallets, blockchain data indexers, and services for estimating transaction fees are the first to be affected. Solutions with a "hardcoded maximum gas limit" are of particular concern. Such tools, it appears, will completely cease to function correctly after the update is activated and will require a mandatory code update.
The core of the issue: EIP-8037 and a new gas dimension
The root of the problem lies in the Ethereum improvement proposal — EIP-8037. This specification introduces a separate dimension of state-gas, which will apply to operations that create new blockchain state. The key nuance: while a regular ETH transfer to an existing address will retain the familiar cost of 21,000 gas units, sending coins to a new, previously unused address will incur an additional fee.
This fundamentally changes the logic of cost calculation. Smart contract and protocol developers who assume that 21,000 gas units covers any ETH transfer will have to revise their algorithms. The same fate awaits code that calculates fees based solely on the amount of gas consumed without accounting for the new dimension.
Testing timeline
According to my data, the public testnet Plataberget has already been launched — this happened on August 13, 2026. The key stage will arrive on August 20, when the Glamsterdam upgrade will be activated on this very network. Ahead lies a critically important month of feedback and refinement of client software. Only after that will tests follow on the more familiar networks for developers, Sepolia and Hoodi, which precedes the mainnet release.
I strongly recommend that teams managing infrastructure do not delay checking their systems on Plataberget. Incidents caused by incompatibility with the new gas model rules could lead to temporary service outages and financial losses for users. This is a case where preparation matters more than speed.
Against the backdrop of these events, it is worth recalling that earlier in August, Ethereum co-founder Vitalik Buterin identified quantum protection and artificial intelligence as the main priorities for network development. The Glamsterdam update is just the first step in a series of transformations awaiting the ecosystem in the coming years.
