The Glamsterdam upgrade is Ethereum’s next scheduled hard fork, targeted for Q4 2026. Announced on 28 July 2026, it aims to increase blockspace capacity and improve validator efficiency. The full EIP list is still being finalised by Ethereum core developers through the All Core Developers call process.
Key Takeaways: Glamsterdam Upgrade at a Glance
- Target date: Q4 2026 (announced 28 July 2026)
- Primary goals: Higher blockspace capacity and better validator efficiency
- Status: EIP selection is ongoing; no proposals are formally confirmed yet
- Follows: The Pectra upgrade, which shipped in early 2025
- India tax note: Network upgrades do not change India’s 30% VDA tax or 1% TDS rules
What Is the Glamsterdam Upgrade?
The Glamsterdam upgrade is Ethereum’s next scheduled hard fork after Pectra. Like all Ethereum hard forks, it bundles multiple Ethereum Improvement Proposals (EIPs) into one coordinated network upgrade. The name follows Ethereum’s tradition of blending city names from Devcon host locations.
The two headline goals of the Glamsterdam upgrade are expanding blockspace and making the validator layer more efficient. Expanded blockspace means more transactions and rollup data can be processed per block, reducing fees for end users and layer-2 networks. Validator efficiency improvements target how nodes propose, attest, and manage deposits or exits, building on work started in Pectra.
Confirmed vs. Still Under Consideration
As of the announcement date, the Ethereum core developer community had not finalised the complete EIP list for the Glamsterdam upgrade. Proposals around blob throughput increases and validator UX changes are reportedly in scope, but none have been formally locked. According to ethereum.org’s official roadmap, upgrades go through a structured process of proposal, review, and client implementation before any EIP is considered included.
Tim Beiko, who coordinates the All Core Developers (ACD) calls, has consistently stated that EIP inclusion is decided call-by-call. Watch the ethereum/pm GitHub repository for official ACD call notes and confirmed EIP lists as the Glamsterdam upgrade progresses.
What Will the Glamsterdam Upgrade Change for Validators?
Validators run the nodes that secure Ethereum’s proof-of-stake network. According to beaconcha.in, there are currently over 1 million active validator slots on the Ethereum beacon chain. Managing that volume creates overhead around attestation aggregation, deposit processing, and exit queues.
The Glamsterdam upgrade is expected to reduce that overhead. Proposed changes include streamlining the validator lifecycle and cutting exit queue wait times. If you are following Lido’s ongoing validator migration, these changes matter directly because large staking operators manage validators at scale.
Ethereum Upgrade Timeline: Roadmap to Glamsterdam 2026
The table below shows the confirmed and targeted ETH network upgrades leading to the Glamsterdam upgrade, based on data from the ethereum/pm GitHub repository and ethereum.org.
| Upgrade Name | Date | Key Focus | Status |
|---|---|---|---|
| Dencun | March 2024 | Proto-danksharding (EIP-4844), blob transactions, lower L2 fees | Completed |
| Pectra | Early 2025 | Validator UX (EIP-7251 max effective balance), account abstraction groundwork | Completed |
| Fusaka | Mid 2026 (targeted) | PeerDAS, further blob scaling | In development |
| Glamsterdam | Q4 2026 (targeted) | Blockspace capacity, ETH validator efficiency | EIP selection ongoing |
Fusaka and Glamsterdam timelines are targets, not hard deadlines. Ethereum upgrades have historically shifted when client teams need more testing time. Dencun went through multiple testnet runs before its March 2024 mainnet launch, per the ethereum/pm call records.
Why Blockspace Capacity Matters
Ethereum processes data for its own transactions and for layer-2 rollups like Arbitrum, Optimism, and Base. Dencun’s blob transactions cut L2 costs significantly. According to L2Beat, average L2 transaction fees dropped by over 90% in the weeks following the Dencun upgrade in March 2024. The Glamsterdam upgrade is expected to push blob throughput further, though the exact EIP is not yet confirmed.
For Indian crypto users trading ETH on platforms that use the Ethereum network, lower gas fees directly reduce the cost of moving assets, interacting with DeFi protocols, or minting NFTs. Exchanges like CoinDCX, ZebPay, and Mudrex that support ETH withdrawals also benefit when on-chain costs drop.
India Tax Context: Does the Glamsterdam Upgrade Change Anything?
No. The Glamsterdam upgrade does not change how the Indian government taxes ETH. You still pay 30% flat tax on VDA gains and 1% TDS on qualifying sell transactions under the Finance Act 2022. SEBI and RBI have not linked regulatory treatment of ETH to its technical upgrade status.

Frequently Asked Questions
What is the Glamsterdam upgrade?
The Glamsterdam upgrade is Ethereum’s next scheduled hard fork, targeted for Q4 2026. It aims to increase blockspace capacity and improve ETH validator efficiency. The full EIP list has not been finalised. Core developers confirm included proposals through the All Core Developers call process before any upgrade ships to mainnet.
What EIPs are included in the Glamsterdam upgrade?
No EIPs have been formally confirmed for the Glamsterdam upgrade as of the July 2026 announcement. Proposals around increased blob throughput and validator lifecycle improvements are reportedly under discussion. The ethereum/pm GitHub repository is the authoritative source for confirmed EIP lists once ACD calls lock them in.
When is Ethereum’s next hard fork after Pectra?
Ethereum’s next hard fork after Pectra is Fusaka, targeted for mid-2026, followed by the Glamsterdam upgrade in Q4 2026. Both are target windows, not fixed dates. Ethereum upgrades can shift if client teams need additional testing time on testnets like Sepolia or Holesky before mainnet launch is approved.
What will the Glamsterdam upgrade change for validators?
The Glamsterdam upgrade is expected to reduce operational overhead for Ethereum validators. Proposed changes include streamlining the validator lifecycle and reducing exit queue wait times. With over 1 million active validator slots on the beacon chain per beaconcha.in, even small efficiency gains have a meaningful impact on node operators and large staking providers like Lido.
How does the Glamsterdam upgrade affect Indian ETH holders?
The Glamsterdam upgrade does not change India’s tax rules on ETH. Indian holders still pay 30% tax on crypto gains and 1% TDS on qualifying sell transactions. Lower gas fees from increased blockspace could reduce transaction costs on the Ethereum network, benefiting users of Indian exchanges like CoinDCX, ZebPay, and Mudrex that support ETH.
