Glamsterdam testnet delayed. @chain_security found the new gas rules could change how existing contracts handle failed calls, so devs paused Hoodi to review it first. no new date yet

Glamsterdam upgrade went live on Ethereum Sepolia yesterday. @Arbitrum Sepolia, @RobinhoodCrypto Testnet, & the @prylabs consensus client continued operating flawlessly despite major protocol changes. Huge credit to @Offchain engineers for making a complex upgrade look routine.

Glamsterdam EIPs moved from "Review" to "Last Call": If you cannot name all 23, here's a quick list: - EIP-2780: Resource-based intrinsic transaction gas - EIP-7688: Forward compatible consensus data structures - EIP-7708: ETH transfers emit a log - EIP-7732: Enshrined Proposer-Builder Separation - EIP-7778: Block Gas Accounting without Refunds - EIP-7843: SLOTNUM opcode - EIP-7928: Block-Level Access Lists - EIP-7954: Increase Maximum Contract Size - EIP-7976: Increase Calldata Floor Cost - EIP-7981: Increase Access List Cost - EIP-7997: Deterministic Factory Contract - EIP-8024: Backward compatible SWAPN, DUPN, EXCHANGE - EIP-8037: State Creation Gas Cost Increase - EIP-8038: State-access gas cost update - EIP-8045: Exclude slashed validators from proposing - EIP-8061: Increase exit and consolidation churn - EIP-8246: Remove SELFDESTRUCT Burn - EIP-8282: Builder Execution Requests - 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 - EIP-8189: snap/2 - BAL-Based State Healing cc @rakitadragan

Glamsterdam devnet-7 is live. More progress on the road to testnet 🚢 On the CL side: - EIP-7688 progressive containers - Updated payload deadlines and builder lifecycle parameters On the EL side: - EIP-2780 and 8037 → state-dependent charges moved from intrinsic gas to runtime, with updated account-creation and calldata-floor accounting - EIP-7928 and 8038 → BAL and SSTORE access-ordering fixes - EIP-8282 → finalized builder deposit and exit contracts, limits, fees, and disable controls Onward.

Glamsterdam devnet-6 is shipping. Tons of progress on the road to testnet. - EIP-8282 brings ePBS builder execution requests, with two new system contracts: On the EL side, the post-bal-devnet-7 work: - New → EIP-2780, 8038 (repricing), 7997, 8246, 8070 (optional) - Changed → 7954 (64 KiB), 8037 (source-based refunds), 7928 (BAL×7702 warming stays status quo) Onward 🚢

Glamsterdam devnet-4 is out Combines consensus-specs alpha-8, bal-devnet-7 EL features, and the new Engine API targetGasLimit path. It also includes the updated EIP-8037 parameters for state creation gas

Lido Glamsterdam on Hoodie Update On yesterday’s ACDE #248# call, Ethereum core developers made the decision to postpone the Glamsterdam upgrade on the Hoodi testnet to allow for further investigation into how EIP-8037 and EIP-8038 interacts with mainnet contracts: This testnet upgrade delay does not affect the mainnet Lido protocol, and no action is required from stETH or wstETH holders. Since Lido’s Hoodi contracts had already been upgraded ahead of the previously scheduled October 26 activation, contributors are currently preparing a Hoodi vote to roll back the fork-specific changes and keep the testnet operational until a new upgrade date is set. Lido DAO contributors are proactively coordinating the rollback with Lido Node Operators and the broader Ethereum ecosystem. If you operate a Hoodi node or validator, please make sure to check both your Execution and Consensus Layer clients for instructions reflecting the postponed activation before October 26. Lido contributors have been screening EIP-8037 against Lido contracts since June and have found no breaking impact on the protocol’s core contracts so far, which has also been independently confirmed by ChainSecurity. The review continues alongside the Ethereum core devs’ broader investigation.
