BlackRock filed a new Form S-1 with the SEC to gain approval for its iShares Staked Ethereum Trust ETF, which will trade under the ticker ETHB and become the company's fourth iShares crypto ETF. The filing's approval is required before trading of the Staked ETH ETF can begin. Staking yield will be treated as income for the Trust. The new ETF is expected to improve returns for shareholders while simultaneously contributing to the economic security of the Ethereum network. The move follows the successful launch of the iShares Ethereum Trust ETF (ETHA), which began trading in July 2024 and currently holds over $11 billion in ETH.

Aztec Network raised 19,476 ETH from its token sale, leveraging Uniswap's Continuous Clearing Auction (CCA) mechanism. The CCA enables automatic liquidity bootstrapping by selling tokens block-by-block, fulfilling orders at multiple clearing prices. Over 16,741 users participated in the sale. Participants can now claim their $AZTEC tokens, which will remain non-transferable until an onchain governance vote, scheduled potentially as early as February 11th, 2026. Users with over 200k tokens can now stake their allocation to secure the network. Aztec Network is a privacy-preserving Layer 2 for private smart contract execution.

ZKsync announced the planned deprecation of its original protocol version, ZKsync Lite, in 2026. Launched in June 2020, ZKsync Lite served as a proof-of-concept that validated key ideas for zero-knowledge (ZK) systems, leading to its current ZKSync Era network. No immediate action is required by users. ZKsync will release a detailed migration plan in the coming year. ZKsync says funds on ZKsync Lite will remain safe and withdrawals to L1 will continue to function throughout the process. The team is focusing on the ZKsync Era network, including the ZK Stack and Prividiums. ZKsync Era currently holds over $480 million in total value secured (TVS) as the 7th largest rollup.

OKX migrated X Layer, it’s native L2 network, from Polygon's Chain Development Kit (CDK) to Optimism’s OP Stack. X Layer aims to provide 5,000 TPS for real-time markets, near-zero slippage for DEX trades, full EVM compatibility, and access to OKX and L2 liquidity. OKX is integrating bridging to X Layer in its self-custodial wallet. The exchange aims to connect its user base of 50 million with the Ethereum ecosystem. With over $25 billion in user assets, OKX currently ranks as a top 5 centralized crypto exchange with $1.9 billion 24-hour trading volume.

L2Beat researcher donnoh.eth published his thoughts to reducing the withdrawal window for Stage 1 Optimistic Rollups from seven days to potentially one day, within the context of the Ethereum L2 Stages Framework. Optimistic rollups currently use a 7-day challenge period to protect bridged funds primarily against a strong censorship attack. The rollup framework dictates that Stage 2 rollups must maintain this 7-day period to fully inherit Ethereum security guarantees. The concern with a shorter period for Stage 1 is the increased vulnerability to soft censorship attacks. In economic censorship attacks, defenders must spend funds on priority tips that are not reimbursed. Donnoh.eth says that the next step for reducing the withdrawal window is to agree on a reasonable defender advantage to require.

ethPandaOps launched a live custody monitoring tool, powered by the dasmon engine, for Peer Data Availability Sampling (DAS) introduced in Fusaka. Fusaka moved Ethereum's Data Availability (DA) from full replication to a sharded architecture via PeerDAS, where individual nodes only store a subset of the data. The tool aims to ensure the network collectively upholds DA guarantees by making Ethereum's new data availability layer observable and verifiable, giving operators, researchers, and users confidence in the network's guarantees. ethPandaOps is an Ethereum DevOps team that provides resources for testing protocol upgrades.

The Ethereum Everywhere team, an Ethereum Foundation team dedicated to amplifying and connecting communities and events globally, is launching an Ethereum Community Hub in Lagos, Nigeria. Located at Web3bridge Africa, the hub will serve as a co-working space and central gathering point for builders, researchers, creators, and artists developing within the Ethereum ecosystem. The hub will host a launch event on December 11, 2025. Two other Ethereum hubs are already live in London and Berlin.

The Prysm consensus layer client experienced a configuration mismatch that impacted Prysm validator participation rates following the Fusaka upgrade. The Prysm team provided a workaround, urging impacted node operators to add the --disable-last-epoch-targets validator flag to their Beacon node. The fix is compatible with client version v7.0.0 and does not require a full Beacon node update. Prysm is the second-largest Ethereum consensus layer client with a 17.49% market share, according to clientdiversity.org. Ethereum's multi-client architecture prevented a single point of failure, ensuring the network continued block production.

Etherealize, Nethermind, and L2Beat published a joint report analyzing Ethereum's L2 ecosystem and its role in the institutional adoption of blockchain for financial infrastructure. The report highlights Ethereum and its L2 ecosystem as the foundation for the global economy’s shift onto onchain rails. The report notes that the shift is being driven by the maturity of the market and increasing regulatory clarity from frameworks like MICA, GENIUS, and CLARITY Acts. L2s offer strategic advantages for institutions, including lower transaction costs, high throughput, and custom controls. L2s can also enable regulatory alignment by using Zero-Knowledge proofs for confidential compliance.

Global asset manager WisdomTree launched the WisdomTree Physical Lido Staked ETH ETP (LIST), the first European Exchange-Traded Product (ETP) to exclusively hold Lido’s stETH. LIST offers institutional investors exposure to staked ETH and onchain staking rewards through a regulated format. The ETP features a fully staked design, which uses stETH's deep liquidity to process creations and redemptions through secondary markets while avoiding the traditional unstaking buffers and validator withdrawal queues. LIST has begun trading with approximately $50 million in assets under management.

ZKsync announced that its Interop solution now allows any chain built with the ZK Stack to natively access the full liquidity of Ethereum L1 DeFi without suffering from fragmented liquidity or slow bridging speed. The ZKsync interop protocol handles the complex mechanics of L2 to L1 interactions, abstracting the process from the user. Users on a ZK Chain can deposit into Aave and borrow assets on Ethereum L1 while remaining entirely on L2. Institutions can now leverage Prividiums, private ZK L2s, to access public L1 market liquidity while maintaining their own governance, privacy, and execution environment.
