EIP-7773 Glamsterdam hard fork meta (Hardfork Meta - Glamsterdam)
No call decision · Other · EIP status Review · created 2024-09-26
A meta EIP that collects the list of EIPs going into the Glamsterdam network upgrade in a single document. It covers the 18 changes confirmed for inclusion, the networking and informational EIPs, and the testnet activation schedule.
Why it is needed
An Ethereum network upgrade (hard fork) bundles dozens of individual change proposals (EIPs) and applies them at once. Whether a proposal is proposed, under review, declined or confirmed keeps changing, so a reference document showing the whole picture is needed. This meta EIP plays that role. It lists every EIP officially Proposed, Considered, Declined or Scheduled for the Glamsterdam upgrade and links to the full specification of each. The activation times of testnets such as Sepolia and Hoodi are also recorded in this document's table as soon as they are set. Users, developers and client teams can all use this one document to see what goes into Glamsterdam.
What changes
Today
- To find out which EIPs are included in Glamsterdam, you have to track the status of each individual proposal separately
- There is no official record that collects testnet and mainnet activation times
After EIP-7773
- 18 scheduled, 5 networking and 2 informational EIPs are organized in one document
- The Sepolia and Hoodi testnet activation times are recorded in the table, and the mainnet time will be filled into the same table once it is decided
Who is affected
- Users: You can see what changes in Glamsterdam from this one document.
- Wallet & app developers: You can prepare in advance by looking at the confirmed list, which includes gas cost changes and a larger contract size limit.
- Client teams: Use it as the reference document for the full specification to implement and for the testnet schedule.
- Validators: You can learn about consensus layer changes such as excluding slashed validators from proposing and increasing exit and consolidation throughput.
In depth
18 EIPs Scheduled for Inclusion (SFI)
Among the confirmed list, the gas and fee accounting changes are EIP-2780 (Resource-Based Intrinsic Transaction Gas), EIP-7778 (Block Gas Accounting without Refunds), EIP-7976 (Increase Calldata Floor Cost), EIP-7981 (Increase Access List Cost), EIP-8037 (State Creation Gas Cost Increase) and EIP-8038 (State-Access Gas Cost Update). For block production structure there are EIP-7732 (Enshrined Proposer-Builder Separation) and EIP-8282 (Builder Execution Requests), and for execution data EIP-7928 (Block-Level Access Lists) and EIP-7708 (ETH Transfers Emit a Log) are included. On the EVM side are EIP-7843 (SLOTNUM Opcode), EIP-7954 (Increase Maximum Contract Size), EIP-8024 (Backward Compatible SWAPN, DUPN, EXCHANGE), EIP-7997 (Deterministic Factory Contract) and EIP-8246 (Remove SELFDESTRUCT Burn). The consensus layer changes are EIP-7688 (Forward Compatible Consensus Data Structures), EIP-8045 (Exclude Slashed Validators from Proposing) and EIP-8061 (Increase Exit and Consolidation Churn).
The definitions of the inclusion stages follow EIP-7723
The definitions of the four statuses this document uses, Scheduled for Inclusion (SFI), Considered for Inclusion (CFI), Declined for Inclusion (DFI) and Proposed for Inclusion (PFI), are in EIP-7723. This meta EIP takes that definition scheme and applies it to Glamsterdam. The document's requires field also lists EIP-7607 and EIP-7723 as prerequisites.
5 networking EIPs and 2 informational EIPs
Separately from the confirmed list, there are networking EIPs that change the communication protocol between nodes. They are EIP-7975 (eth/70 - Partial Block Receipt Lists), EIP-8070 (eth/72 - Sparse Blobpool), EIP-8136 (Cell-Level Deltas for Data Column Broadcast), EIP-8159 (eth/71 - Block Access List Exchange) and EIP-8189 (snap/2 - BAL-Based State Healing). Of these, EIP-8159 and EIP-8189 are protocols that use the Block Access List (BAL, EIP-7928) from the confirmed list for node synchronization. The Informational EIPs listed are EIP-7904 (Compute Gas Cost Analysis) and EIP-8261 (Gas Limit Schedule).
Activation schedule: two testnets confirmed, mainnet undecided
The Sepolia testnet activates at epoch 353024, timestamp 1791294816 (2026-10-06 13:53:36 UTC). The Hoodi testnet is at epoch 132352, timestamp 1793036568 (2026-10-26 17:42:48 UTC). The mainnet cell is empty. The source says the table rows will be filled in as client teams decide on activation times.
Mascot and the nature of the document
The Glamsterdam mascot was chosen as the polar bear following the EIP-8066 process. The Rationale section describes the purpose of this meta EIP as giving a full overview of all changes included in Glamsterdam and providing links to the full specifications. Because it is not a document that directly changes protocol behavior, the Security Considerations section is None.
Status is Review, and the list can still change
At the ACDT #88 call on July 20, 2025, it was confirmed that EIP-7773 would move to Review status, with no objections. This means the document that bundles the full upgrade specification has entered the review stage. However, since the status is Review, the content of the document can still change. The mainnet activation time has not been set yet either, and the table will be filled in as decisions are made.
