Ethereum Prepares Glamsterdam for Launch in Hoodi on October 26

The Ethereum Foundation has scheduled the launch of the Glamsterdam upgrade on the Hoodi testnet for October 26, 2026. This is important for developers, validators, and those following ETH. The token itself is currently trading around $2 363.09.

According to the source, the network will receive a gas limit of 200 million. By comparison, the current average mainnet gas limit is 60.00 million. That means the test level in Hoodi is roughly 3.3 times higher.

What exactly will Glamsterdam change?

Glamsterdam combines execution-layer changes from Amsterdam and consensus-layer changes from Gloas. The upgrade centers on two things: ePBS and BAL. The first separates the roles of block proposers and block builders. The second adds data access lists at the block level.

In simple terms, Ethereum wants to better separate responsibilities within the protocol. This should give validators more time to verify transactions and reduce reliance on trusted intermediaries. For a network where every second matters, that is no small thing.

There is also a technical detail that matters for engineers. According to ethereum.org, ePBS increases the data propagation window from about 2 seconds to 9 seconds. This gives more room for synchronization, but also requires careful work from clients.

Why is this upgrade important right now?

Because Ethereum is already hitting the limits of its old settings. The material also says Glamsterdam will change the gas calculation rules. This is needed to more accurately account for network load and blockchain state growth.

EIP-8037 and EIP-8038 are mentioned separately. They revise the cost of creating state and accessing it. There are also other changes, including Ethereum transfer logs, a new opcode for the slot number, a larger maximum smart contract size, and new rules for validators.

For Ukrainian users, there is a practical takeaway here. If you hold ETH or work with a dApp, changes in gas rules may affect contract behavior. This is especially true if they depend on fixed gas limits.

Market reaction

The market is taking this calmly for now. ETH is trading around $2 363.09, and the daily range was $2 362.10–$2 426.58. Over the day, the asset fell by 1.56%.

There is also context from the network itself. Hoodi will receive a gas limit of 200 million, just as Sepolia did during activation on October 6. This is a test step, but it shows the direction the team is moving in.

During earlier testing on Sepolia, developers found a vulnerability in the block auction system. It allowed attackers to outbid legitimate bids and fail to relay transactions after winning.

That is why the launch in Hoodi matters not just as a formality. It should show whether the weak point has been fixed before the move to the mainnet. The date for mainnet has not yet been announced.

• Glamsterdam will be activated in Hoodi on October 26, 2026.

• The gas limit on the testnet will be raised to 200 million.

• The current average mainnet gas limit is 60.00 million.

• ETH is trading around $2 363.09.

• The daily price change is -1.56%.

What does this mean for investors?

For long-term ETH holders, the main signal is simple: development is not standing still. But that does not yet mean a quick mainnet launch. For now, only the Hoodi test date is known, not the date of the final upgrade.

For node operators and validators, the picture is more concrete. Before the launch, they need to update execution and consensus clients to compatible versions. The list already includes Lodestar 1.50.0, Nimbus 26.10.1, Prysm v7.3.0, Teku 26.10.1, Besu 26.10.0, Ethrex 30.0.0-rc.2, and Nethermind 2.2.0. For some clients, including Geth, Erigon, Reth, Lighthouse, and Grandine, confirmed versions have not yet been specified.

dApp developers should separately test contracts on Sepolia and Hoodi. If a contract is tightly tied to old assumptions about gas remaining, it may behave differently after the upgrade. This is one of those cases where testing is cheaper than a mainnet mistake.

There is one more nuance. According to the Ethereum Foundation, Hoodi has a gas limit of 200 million, while the current average mainnet level is only 60.00 million. If similar settings are eventually brought to the main network, throughput will increase noticeably. But for now, this is only a test.

Frequently asked questions

When will Glamsterdam launch in Hoodi?

The launch on the Hoodi testnet is scheduled for October 26, 2026. According to the Ethereum Foundation, the activation will take place at epoch 132 352 and slot 4 235 264.

Do ETH holders need to do anything?

No, at the Hoodi launch stage, mainnet users do not need to do anything. This is a test activation, and the mainnet launch date has not yet been announced.

What will change most for developers?

The most sensitive changes concern gas rules and contract behavior. If a project relies on fixed gas limits, it needs to be checked again for compatibility.

For now, Glamsterdam looks like technical preparation for a larger restructuring of Ethereum, rather than a ready market catalyst. If you need to quickly sell Ethereum ETH on Monobank, you can do it without extra steps and track the rate more conveniently.
