Ethereum Postpones Glamsterdam Hoodi Testnet Over Security Risks

Ethereum developers have delayed the Glamsterdam upgrade's Hoodi testnet launch after a security audit uncovered meaningful risks tied to the upgrade's proposed gas changes, according to Cointelegraph. The decision reflects a growing emphasis on caution within the Ethereum development community as upgrades grow increasingly complex.

ChainSecurity, the firm behind the disclosure, identified 13 real-world smart contract examples that could be adversely affected by the gas modifications Glamsterdam would introduce. The firm is now coordinating responsible disclosure directly with the projects operating those contracts, a standard industry practice designed to give developers time to patch vulnerabilities before details become public.

Gas changes in Ethereum upgrades are historically sensitive because smart contracts are often written with hard-coded gas assumptions baked in. When those parameters shift, contracts that functioned correctly under the old rules can behave unexpectedly — or fail entirely — under the new ones. The breadth of 13 affected real-world contracts signals that the risk is not merely theoretical.

The delay underscores the difficulty of iterating on a live, high-value blockchain ecosystem where millions of dollars in assets depend on contract reliability. Testnets like Hoodi exist precisely to surface these issues before they reach mainnet, but the security flag arrived early enough to pause even that intermediate step. No revised launch timeline has been publicly confirmed at this stage.
