Walletbeat, the open repository of EVM-compatible wallets that bills itself as "the L2BEAT of wallets," is now out of beta and live at walletbeat.eth, according to an announcement from the team amplified by the Ethereum account on X. The site had previously run on a beta domain.

• The project catalogs wallets across EVM networks, tracking their features, practices, and support for standards
• The move off beta and onto the ENS domain was tracked in the project's GitHub issue tracker
• Public repo remains at github.com/walletbeat/walletbeat

The Devcon team announced the next edition of Ethereum's flagship developer conference: Devcon 9 will take place October 11–13, 2027 in Lisbon, Portugal, following the close of Devcon 8 in Mumbai. The announcement was amplified by the Ethereum account on X on November 6.

Lisbon was selected as a low-friction European hub for the conference, with strong international connectivity and proven capacity for large events. Details on venue, tickets, and agenda have not yet been released.

The Ethereum Foundation's Glamsterdam network upgrade activated on Sepolia on October 6, adding ePBS, block-level access lists, and gas repricing via EIP-8037 and EIP-8038, which rework gas charges for certain operations and for state. The Hoodi testnet activation remains postponed with no new date after Chainsecurity flagged projects that would be vulnerable post-Glamsterdam because they rely on invariants the EIPs break.

On November 6, EF developer Marius van der Wijden confirmed in a blog post that ACD decided to delay the hardfork process and not fork Hoodi until the issues are resolved. The EF published a repository of the eight broken invariants with examples and prompts, and is asking contract developers and auditors to check whether their projects rely on any of them, reporting to glamsterdam@ethereum.org.

• Details of the potential issues are available in the Chainsecurity blog post and a community-built repricing tool
• Breaking change for app developers: gas repricing removes the fixed maximum gas ceiling, so wallets, indexers, and gas estimators assuming a hardcapped limit must be updated

The Aztec Foundation introduced Aztec Tierra (Alpha V6), a network upgrade for its privacy-focused Ethereum layer 2, in an announcement amplified by the Ethereum account on X. The release fixes a critical vulnerability found in the previous V5 version, adds security hardening, and includes formal verification of core cryptographic components plus an AI-powered testing harness.

Performance gains include client-side proofs generated in roughly one second on a standard device — about twice as fast as before — and Ethereum-to-Aztec messages delivered in as little as 12 seconds, down from an average of two minutes.

• Ships with a refreshed brand and website, plus a slate of private apps led by the revived zk.money payments app
• Other launches include Galactica (private AI inference), Nemi (private perpetuals), the Nulo wallet, and Rolling Chat
• Aztec describes itself as Ethereum's only decentralized L2 with fully programmable privacy — no backdoors, no gatekeepers

L2BEAT, the Ethereum layer-2 data and risk-assessment platform, has been renamed ETHBEAT, according to an announcement amplified by the Ethereum account on X. The team said its work had clearly outgrown the "L2" label, and the new name reflects a mission that now spans the broader Ethereum ecosystem.

• Research scope now extends beyond layer 2 to privacy, interoperability, staking, tokens, and ZK, while L2 monitoring continues
• The rebrand was rolled out across the project's codebase and channels, per the team
• ETHBEAT stays focused on accountability and transparency, the role L2BEAT played for over five years

The MIST.cash team announced that recursive Groth16 proofs are now ~38% cheaper to prove, after their paper "Pairing Proofs and Polynomial Ring Toolkit" by Shrameet Shantz was accepted at CHES 2027 (TCHES). The announcement was amplified by the Ethereum account on X on October 26.

The polynomial-ring approach verifies a BN254 or BLS12-381 Groth16 proof inside a BN254 circuit with a single generic verifier circuit for both curves. It takes roughly 38% (BN254) and 31% (BLS12-381) fewer R1CS constraints than gnark's own pairing — at the cost of two extra verifier pairings.

• Open-source implementation (polyring) is unaudited and intended for research/testnet use only
• ~34–44% less witness solve time than gnark's pairing, per the team's benchmarks

The Devcon 8 schedule is officially live, and the Devcon App is now available in Early Access, according to the Devcon team on X. The app lets attendees explore sessions, discover speakers, and plan their days ahead of the conference.

Devcon 8 takes place November 3–6, 2026 in Mumbai, India at the Jio World Center. Ticket sales are already underway.

The Cloaked browser extension is live, letting users connect to Ethereum apps with a fresh address each time, according to an announcement from @staycloakedxyz amplified by the Ethereum ecosystem account on X. Every payment lands at a fresh Cloaked address owned by the user, with stealth addresses and Privacy Pools at the core of the protocol.

• Available as a Chromium/Chrome extension with a toolbar popup and side panel for reviewing wallet requests
• Users fund a Cloaked address from an external wallet, then use it privately across supported dapps
• No native mobile or desktop app — use is via the web app or extension, per Cloaked's docs

The Ethereum account on X announced a new research report, Alternatives to Concentrated AI, co-authored with Decentralization Research Center (DRC) Head of Research Samuel Vance-Law. It frames AI policy not as a choice between slowing innovation and accelerating at any cost, but as a question of who gets to build, access, and govern these systems.

The report draws on 36 interviews and maps nearly 30 alternatives to concentrated control across the AI stack, spanning chip manufacturing, training, and deployment layers. It includes case studies written by builders at OpenMined, the Ethereum Foundation, and Civic AI.

• Published by the DRC at thedrcenter.org
• Concludes that while chip manufacturing and frontier-scale training remain concentrated, working alternatives now exist at nearly every other layer
• Also available as a paper on SSRN by Vance-Law and Kyle Bligen

JPMorgan's JPM Coin (JPMD) USD deposit token is now live on Ethereum, extending from Base to the Ethereum L1, according to an announcement amplified by the Ethereum ecosystem account on X. JPMD gives approved J.P. Morgan institutional clients native onchain cash on Ethereum, alongside the assets and collateral they already transact with.
