Ethereum’s Glamsterdam Testnet Launch Nears: Can ETH Rally Back to $2,800?

Ethereum’s Glamsterdam work sits inside the network’s normal upgrade path, where changes are first pushed through testing before any wider release. Hoodi is the next stop named for this upgrade, and the October 26 timetable shows the project is still moving through its staged rollout. The proposal also includes a 200 million gas limit, which places block capacity inside the same upgrade discussion.

For builders and users, Glamsterdam matters because it changes how blocks may be assembled and handled, not just what Ethereum can eventually support. Enshrined proposer-builder separation and block-level access lists point to changes in transaction ordering and network efficiency, so teams that depend on contract behavior and block structure will have to watch the test phase closely. The delay after security developers flagged risks to existing contracts means developers now have more time to check assumptions before any wider deployment.

The trade-off here is between moving Ethereum toward higher throughput and preserving compatibility for contracts already live on the network. A higher gas limit and lower-level block changes can improve capacity and efficiency, but they also put more pressure on the system that existing applications already rely on. That tension is especially sharp on Ethereum, where upgrades are meant to scale the chain without breaking the software built on top of it.

What is still open is whether the Hoodi testnet date holds and what specific contract-risk issues the security developers identified. The next concrete signal would be the outcome of testing and any further update to the upgrade schedule. Until then, the public only knows that the rollout is planned and that concerns about existing contracts have already pushed the process into delay.
