Ethereum delays Glamsterdam Hoodi testnet launch over security risks

By AI CryptoNews · 23 Oct 2026 16:01 UTC · Not financial advice

Sometimes slowing down is the smartest move. Ethereum's developers just hit the brakes on a major upgrade after security researchers found it could quietly break existing apps built on the network.

What happened

The planned launch of the Glamsterdam upgrade on the Hoodi testnet (a testnet is basically a practice version of Ethereum where developers test new features safely) has been delayed. The reason is a security concern flagged by a firm called ChainSecurity, which specializes in auditing blockchain code.

ChainSecurity found 13 real-world smart contracts that could be affected by gas changes coming in Glamsterdam. Gas refers to the fees users pay to run actions on Ethereum. Changes to how gas works can accidentally break smart contracts, which are the self-running programs that power most crypto apps. The firm is now working directly with the affected projects to warn them before anything goes live.

Why it matters for you

If you use any DeFi apps (decentralized finance platforms where you can lend, borrow, or trade crypto without a bank), some of the ones you rely on could be among the 13 flagged. A broken smart contract can mean stuck funds or unexpected errors, which is obviously not great.

The good news is that this is exactly how responsible security research is supposed to work. The problem was caught before launch, not after. For regular Ethereum holders, this delay probably does not change much day to day, but it is a reminder that complex upgrades carry real risks.

What to watch next

Keep an eye on whether ChainSecurity and the Ethereum developer community decide the gas changes need to be redesigned, or if the affected projects can simply update their own code before the testnet goes live. A new launch date for the Hoodi testnet should follow once those conversations wrap up.

Frequently Asked Questions

Is the Glamsterdam upgrade cancelled?

No, it is delayed, not cancelled. Developers are working through the security concerns before moving forward with the testnet launch.

Should I be worried about my Ethereum or DeFi funds?

For now, nothing has changed on the main Ethereum network, so your funds are not at immediate risk. The issue was caught during pre-launch testing, which is the system working as intended.

What is a testnet and why does it matter?

A testnet is a copy of the real blockchain used purely for testing, where no real money is at stake. Delays there are much better than problems on the live network where real funds could be affected.
