Ethereum Pushes Back Glamsterdam Fork Over Contract Bugs
Ethereum engineers paused the Glamsterdam testnet upgrade after auditors spotted bugs that could break live smart contracts. Wallet users and app builders relying on Ethereum should note this: safety checks now come before new features ship.
What actually happened
Audit firm Chainsecurity flagged several apps that would stop working once Glamsterdam activates, because EIP-8037 and EIP-8038 change how gas gets charged for certain actions, per the Ethereum Foundation blog. Developers are now checking eight separate contract assumptions before restarting the Hoodi fork, according to Cointelegraph. Meanwhile, layer-2 network Base rolled out its Denim upgrade on 5 November 2026, cutting block times to 200 milliseconds and replacing its older Flashblocks tool. Ethereum co-founder Vitalik Buterin said the industry's main job for the next two years is staying secure, not beating rivals, after a string of exchange hacks. At publication, ETH traded near $2,223, down 2.43% in 24 hours, with $15.30 billion (USD) in daily volume and a $271.59 billion (USD) market cap.
How we got here
The caution follows a rough month for Ethereum security. In October, hackers behind a $6.34 billion (USD) breach at Binance abused EIP-7702, an account-abstraction feature, to hijack wallet permissions through malicious contracts, a method Binance could not stop by simply freezing withdrawals, per Wu Blockchain. That breach, plus a market-wide selloff around the US midterm elections, pushed Buterin to call for tougher defenses at exchanges and custodians. Catching bugs before mainnet, instead of after, has become the standard approach for Ethereum's core developers since then.
Why this matters for you
For everyday wallet holders, this delay means Ethereum's base layer keeps its current rules a bit longer, nothing changes for daily transactions yet. For developers building inside the bonuz ecosystem or similar apps, it buys extra time to test contracts against Glamsterdam's new gas charges before anything breaks in production. Base's Denim upgrade shows layer-2 networks are not waiting on Ethereum's mainnet calendar, faster blocks there could mean quicker confirmations for apps and wallets that settle through Base. Today's ETH price dip looks tied to broader market mood, not to the Glamsterdam news itself.
The bigger question
How much delay is acceptable before shipping a technically finished upgrade, when auditors flag risks touching only a handful of contracts? Ethereum's current answer seems to be: as long as it takes to get it right. Whether that patience holds once upgrades grow more complex, and whether wallet apps can absorb unpredictable fork timelines, remains an open question for the whole industry.
What to watch
No new date exists yet for the Hoodi testnet fork, developers say Glamsterdam waits until all eight flagged issues clear. Base's Denim upgrade is already live on mainnet since 5 November 2026. Circle's Q3 2026 report showed USDC circulation averaging $73.3 billion (USD). bonuz.market will update the Glamsterdam timeline once Ethereum developers confirm a new date.
