• Lido launches the strETH DeFi vault.

• EF publishes Fusaka Mainnet Announcement.

• Google Finance integrates Polymarket data.

• Guantlet pauses withdrawals amid deUSD depeg.

Lido Finance launched stRATEGY, a new curated DeFi vault built on Mellow Protocol’s Core Vaults infrastructure. The vault offers diversified exposure to an stETH DeFi strategy involving Aave, Ethena, and Uniswap. Users can deposit ETH, WETH, or wstETH to receive strETH, representing their share in the vault. The vault automatically manages allocation, monitoring, and rebalancing, giving users simple access to curated DeFi yield opportunities. strETH holders also earn Mellow points rewards. The vault takes a 1% annual management fee and 10% performance fee on rewards, which are reflected in the token’s price.

The Ethereum Foundation published the official Fusaka Mainnet Announcement, calling on all Ethereum node operators to update both execution and consensus clients before the upgrade activates on December 3, 2025 at slot 13,164,544. Fusaka-ready client releases are available from Lighthouse, Teku, Nimbus, Geth, Besu, Erigon, Nethermind, and Reth. Prysm is the only client that has not yet released a production-ready version. Fusaka introduces 12 EIPs that enhance scalability, performance, and user experience. Its headline feature, PeerDAS (EIP-7594), enables higher blob throughput to reduce Layer 2 transaction costs. Following activation, Blob Parameter Only (BPO) forks will gradually raise per-block blob limits to further expand network capacity. Fusaka marks the second upgrade shipped this year, following Pectra in May 2025.

Google Finance is adding support for prediction markets data from Kalshi and Polymarket, the world’s largest prediction market built on Polygon PoS. The integration allows users see real-time probabilities for future market events directly in search results. The feature is powered by Google’s Gemini AI models and will roll out first to Google Labs users in the U.S. over the coming weeks, with broader access to follow. Google Finance is Google’s platform for financial data, research, and market insights.

Aragon introduced the Ethereum Protocol Advocacy Alliance (EPAA), a new organization for coordinating policy efforts among teams building onchain infrastructure. Members include Aave, Aragon, Curve Finance, Lido Finance, Spark Protocol, The Graph, and Uniswap, which collectively secure over $100 billion in assets. Formed to counter the dominance of crypto lobbying from centralized actors, the Alliance aims to protect the neutrality of the protocol layer, advance onchain transparency, preserve flexibility for innovation, and uphold global, permissionless access. The alliance will collaborate with advocacy partners such as the DeFi Education Fund, the Decentralization Research Center, and the European Crypto Initiative.

Aztec founder Zachary Williamson published a privacy manifesto confronting the dark incentives of the Information Age, namely, the monetization of human attention and data. While he shares Vitalik Buterin’s techno-optimism, he argues that technology is neutral and its outcomes depend on the incentives that drive it. He proposes a technical and moral revolution built on zero-knowledge cryptography and privacy-preserving blockchains, allowing users to prove facts without revealing personal data and reclaim their digital agency as customers rather than commodities. Williamson calls on developers to build privacy-first systems using the Noir programming language on Aztec Network, a privacy-focused Layer 2 on Ethereum.

The Ethereum ecosystem, including L2 networks, hit a record peak throughput of 24,000 transactions per second on Tuesday. The milestone came as analytics platform growthepie incorporated data from Lighter, a perpetuals-focused L2, to its ecoystem TPS tracker. Lighter topped the charts with about 3,600 TPS, followed by Base.

Ethereum client teams Lighthouse, Geth, Teku, Erigon, and Lodestar have released Fusaka-ready versions of their clients. Fusaka is Ethereum’s next upgrade, scheduled to go live on mainnet on December 3, 2025, at 21:49:11 UTC. Node operators must update their client software ahead of the activation. Validators running MEV-Boost must also update to Fusaka-ready v1.10. Fusaka introduces 12 EIPs, delivering improvements in scaling, performance, and user experience. The headline feature, PeerDAS (EIP-7594), enables higher blob throughput, reducing L2 transaction costs. Blob Parameter Only forks will follow, designed to further expand blob capacity by gradually increasing per-block blob limits.

• Lighthouse v8.0.0 release

• Geth v1.16.7 release

• Besu v25.11.0 release

• Erigon v3.2.2 release

• Teku v25.11.0 release

• Nimbus v0.2.2 release

• Lodestar 1.36.0 release

• MEV-Boost v1.10 release

Linea activated its burn mechanism on mainnet, automatically burning 20% of net ETH gas fees from every transaction and using the remaining 80% to buy back and burn LINEA tokens. ETH remains the native gas token on the network. The surplus gas fees are collected by a dedicated fee contract, which executes both burns. Linea also retroactively burned all surplus fees accumulated since September 11, 2025, totaling about 18 ETH and 20 million LINEA burned to date. Linea is an EVM-equivalent ZK rollup developed by Consensys, designed to deepen alignment with Ethereum.

ZKsync published a proposal seeking to expand the role of its ZK token from governance to utility, including a new buyback and burn mechanism. The proposal aims to bring value accrual to the ZK token through two mechanisms: onchain interoperability fees, which collect fees from transfers between ZKsync chains and Prividiums, and offchain enterprise licensing, which brings revenue from banks and institutions licensing advanced ZK modules. Proceeds from the value accrual would flow into a governance-controlled system that buys back $ZK and allocates it toward staking rewards, ZK token burns, and treasury funding. The move aims to ensure that the ZKsync ecosystem benefits from the Elastic Network. The proposal is currently open for community feedback.

Vitalik Buterin published a forum post proposing to reduce the current 7-day withdrawal window for stage 1 optimistic rollups to 1-2 days. He explained that shortening the time window could reduce costs for liquidity providers by 3-7x. Vitalik noted that 1-2 days is sufficient to handle all issues except a 51% censorship attack, and proposed a “delay extension switch” to allow any security council member to extend the withdrawal window to 7 days or longer if needed. For stage 2 rollups, which aim for full Ethereum-level security, the 7-day window should remain
