The Ethereum Foundation<\/strong> is sounding the alarm ahead of its next major upgrade. Glamsterdam<\/strong>, which introduces a new gas calculation model, could render certain existing tools incompatible \u2014 and developers are being urged to act now.<\/p>\n\n\n\n

The message is clear: test early on the Plataberget<\/strong> testnet before the upgrade rolls out to other test environments and, ultimately, the Ethereum mainnet<\/strong>. A precaution that speaks volumes about the scale of the changes ahead.<\/p>\n\n\n\n

Behind this technical warning lies a significant challenge for the Ethereum<\/strong> ecosystem: ensuring a smooth transition to a deeply overhauled gas model without disrupting the DeFi<\/strong> protocols, wallets, and infrastructure tools that keep the network running day to day.<\/p>\n\n\n\n

Glamsterdam: What Really Changes With the New Gas Model<\/h2>\n\n\n\n

Glamsterdam<\/strong> is the next major Ethereum<\/a> upgrade, expected to follow Pectra. Its most structural change concerns the gas model<\/strong> \u2014 that is, the way the network calculates and charges for the cost of executing transactions and smart contracts. This deep-level overhaul aims to make Ethereum more efficient and more predictable for both users and developers.<\/p>\n\n\n\n

The problem is that many tools \u2014 indexers, transaction simulators, development frameworks, and wallet interfaces<\/strong> \u2014 rely on precise assumptions about how gas currently behaves. A change to the underlying model can be enough to make these tools malfunction<\/strong>, or even trigger silent errors that are difficult to catch in production. The Ethereum Foundation has therefore deemed it necessary to alert the ecosystem well in advance.<\/p>\n\n\n\n

The Plataberget<\/strong> testnet has been set up specifically to allow teams to test their tools’ compatibility with Glamsterdam before the upgrade propagates to other testnets such as Sepolia<\/strong> or Holesky<\/strong>, and then to mainnet. This is a critical testing window that developers simply cannot afford to ignore.<\/p>\n\n\n\n

Why This Warning Is a Strong Signal for the Ethereum Ecosystem<\/h2>\n\n\n\n

The Ethereum Foundation<\/strong> does not often communicate this directly about compatibility risks. This proactive statement signals that the changes introduced by Glamsterdam are significant enough to warrant heightened vigilance<\/strong>. In the Ethereum ecosystem, where billions of dollars in value flow daily through DeFi<\/strong> protocols, bridges, and on-chain applications, an undetected incompatibility can have serious consequences.<\/p>\n\n\n\n

The teams most exposed are those maintaining infrastructure tools: client nodes, RPC providers, simulation tools such as Tenderly or Foundry, and testing frameworks<\/strong>. These actors will need to update their code to reflect the new gas logic before mainnet deployment. DeFi<\/strong> protocols that rely on gas estimations to optimize their execution strategies are also firmly in the spotlight.<\/p>\n\n\n\n

\"Glamsterdam:<\/figure>\n\n\n\n

This situation echoes previous upgrades such as EIP-1559<\/strong> and the transition to Proof of Stake<\/a> (The Merge), both of which required significant adaptations from developers. The difference this time: the warning is coming early, giving the ecosystem time to adjust without rushing. A sign of growing maturity in Ethereum’s technical governance.<\/p>\n\n\n\n

What Developers Should Do Right Now<\/h2>\n\n\n\n

The Ethereum Foundation<\/strong>‘s recommendation is unambiguous: deploy and test on Plataberget immediately<\/strong>. This testnet, dedicated to Glamsterdam, is the only environment that accurately reflects the new gas model. Waiting for the next general-purpose testnets means risking the discovery of incompatibilities too late in the deployment cycle.<\/p>\n\n\n\n

Developers are advised to prioritize checking:<\/p>\n\n\n\n
