Ethereum’s Glamsterdam Roadmap Takes Shape After Soldøgn Interop
The Ethereum Foundation Protocol cluster published an update from a week-long core dev interop gathering in Svalbard, Norway, outlining the key milestones reached for the upcoming Glamsterdam upgrade. Teams focused on hardening and preparation across nearly all clients.
A 200M gas limit floor was established as a credible post-Glamsterdam target, derived from convergence of ePBS, BAL optimizations, and EIP-8037 repricing. ePBS is now stabilized with a multi-client Glamsterdam devnet running and the external builders pipeline tested end-to-end.
EIP-8037 was finalized, adopting a fixed cost_per_state_byte model with full repricing numbers delivered on bal-devnet-6. On the Hegotá side, FOCIL prototypes are functional, native AA requirements were scoped, and the multi-client devnet is the immediate next step.
The week also marked a leadership transition in the EF Protocol cluster. Will Corcoran, Kev Wedderburn, and Fredrik will take over from Tim Beiko, Barnabé Monnot, and Alex Stokes — Barnabé and Tim are moving on from the EF, while Alex Stokes will be on sabbatical. Together, they coordinated shipping Fusaka to mainnet in December 2025.
For AA builders, cheaper state access via EIP-8037 and a path toward native AA in Hegotá reduce the cost of running batched UserOps and gasless flows at scale. Beyond immediate upgrade work, Soldøgn participants also discussed Ethereum’s broader long-term account abstraction goals, including support for alternative signature schemes, native batching, key rotation and recovery, signature aggregation compatibility, relayerless sponsorship, and unified cross-chain account identities. Discussions also emphasized preserving Ethereum’s core constraints around public mempool compatibility, censorship resistance, bounded validation costs and minimizing complexity for L2s. The direction signals continued momentum toward more native protocol-level AA capabilities while maintaining compatibility with future roadmap items such as FOCIL, statelessness and zkEVMs. Glamsterdam devnets are now live.
EIP-7851: Code-Controlled EOA Delegation
We covered EIP-7851 in an earlier issue. The spec has since been significantly updated by Liyi Guo and Nicolas Consigny, and the new design is worth a close look for any team building on EIP-7702.
The proposal has been redesigned around a new EVM opcode, SETSELFDELEGATE. Rather than a separate system contract with a time-delayed deactivation, wallet code itself calls the opcode to rewrite the account’s delegation prefix from 0xef0100 to 0xef0101, instantly and permanently disabling the original ECDSA key’s authority.
The core invariant: once ECDSA authority is disabled, it can never be restored. However, the delegate address is not frozen; the wallet code can still call SETSELFDELEGATE to update the delegation target while staying ECDSA-disabled. It is the original key that is burned, not the ability to redelegate through code.
This is a cleaner design than the previous version. The old spec required EOAs to call a system contract and wait 7 days before deactivation finalized. The new approach puts control directly in the wallet code, with no delay and no separate scheduling step.
The post-quantum angle remains the same: permanently disabling ECDSA authority removes the signature scheme most exposed to future quantum computing threats, while smart wallet code can adopt quantum-safe signing from day one.
Ethereum Foundation Launches Clear Signing Standard to End Blind Approvals
An Ethereum Working Group of wallet developers, security firms, and the EF’s Trillion Dollar Security Initiative launched an open standard to end blind signing — a structural flaw behind billions in user losses, including the Bybit hack.
The standard centers on ERC-7730, a shared format for human-readable transaction descriptions. Anyone can submit descriptors to a public registry at clearsigning.org; accuracy is verified through independent attestations, and wallets decide which sources they trust.
The 1TS Initiative hosts the registry as a credibly neutral steward. Tooling, including Rust and TypeScript libraries funded through 1TS, is available to developers at clearsigning.org.
Contributors include MetaMask, Trezor, Fireblocks, WalletConnect, Keycard, ZKnox, Sourcify, Cyfrin, Zama, Argot, and independent contributors. Ledger is credited for initiating ERC-7730 and the early tooling, infrastructure, and educational efforts.
For EIP-7702 and ERC-4337 teams, batched transactions and UserOperations are the hardest flows for users to verify today. ERC-7730 descriptors let your contracts present human-readable summaries — a prerequisite for institutional adoption.
Silence Laboratories Launches First Quantum-Safe MPC Infrastructure for Digital Asset Custody
Silence Laboratories launched what it describes as the first quantum-safe MPC infrastructure for digital asset custody. The system combines ML-DSA, NIST’s 2024 post-quantum signature standard, with MPC, letting institutions begin migrating without replacing their existing custody setup.
The infrastructure is modular, integrating with existing governance frameworks rather than requiring a full rebuild. It also incorporates trusted execution environments such as Google Cloud Confidential Computing to isolate sensitive signing operations.
Launch partners include BitGo, ZenGo, EigenLayer, Networks for Humanity, and Bron Wallet as wallet builders, with Infosys as system integrator. The infrastructure is available immediately to select design partners.
Read alongside EIP-7851, a concrete post-quantum migration path is forming: migrate to EIP-7702, deactivate the ECDSA key via EIP-7851, and back the new signing authority with quantum-safe MPC. For wallet and AA teams starting to plan for key security, both deserve close attention.
