Base activates Denim upgrade. The fourth Base upgrade replaces Flashblocks with five canonical blocks per second, adds millisecond time and changes B20 transfer controls. Happy Thursday, November 5, 2026. Base activates its Denim upgrade. A Reth bug causes some nodes to stall. Lido adds Firelight loss protection to Earn vaults. And European asset manager Amundi launches a tokenized fund on Ethereum. Support ETH Daily Security. A small donation can help ETH Daily Security reach the threshold to qualify for TheDAO Fund's vote. ETH Daily is building a public hub to help Ethereum users find tools that protect them. Support the initiative here. Base activated Denim on mainnet, its fourth network upgrade introducing native 200ms block times, a 10x speed improvement over its previous 2 second block times. The update replaces 200ms Flashblock block confirmations with 200ms canonical blocks. The upgrade also brings BaseTime, a new mechanism that gives smart contracts and RPC clients millisecond-resolution timestamps while preserving full compatibility with Ethereum's existing second-based time model. Developers on Base are advised to review any logic that measures time in block counts. Denim also adds new compliance controls to the B20 token standard. Issuers can invert reusable compliance policies, executor policies now apply to every transfer path, and transfers, mints or seizures to a token's own address fail to avoid locked funds. The upgrade aims to support faster trading and payments. Reth bug stalls nodes. A bug in Reth's legacy state-root calculation caused some nodes on the execution layer to compute an incorrect root. A carefully crafted transaction interacting with certain contract storage layouts can trigger the edge case. The bug can cause unpatched nodes to stall or return incorrect state proofs. The issue affects Reth-based nodes and block builders using the legacy calculator, including OP Stack deployments. Node operators should update to patched releases, including Reth v2.10.0, OP Reth v2.8.1, and Base v1.5.3. Base said it verified its current state root, patched its block builders, and released v1.5.3 to prevent validators from halting on invalid roots. The reported issue does not affect OP Stack or Base withdrawal systems, or ecosystem bridges that rely on receipt roots or multisignatures rather than state roots. Lido adds Firelight loss protection. Lido added Firelight, an onchain cover protocol, as an added layer of loss protection for its EarnETH and EarnUSD vault products. During an initial 30-day period, Firelight will cover eligible, approved losses up to 5.7% of EarnETH's TVL and 8% of EarnUSD's. Coverage applies at the vault level, meaning no action is needed from depositors. Eligible events include smart contract risks, oracle and governance failures, plus certain mechanism failures that cause bad debt, depegs or redemption problems. The Lido DAO's existing protection fund serves as a second layer of protection to absorb any remaining eligible loss. The protection fund holds $3 million in wstETH positions in EarnETH and $2 million in USDC positions in EarnUSD. The protection fund works by burning the Lido DAO's shares after a confirmed loss reaches its threshold. The two layers have separate limits and conditions. Misc news.

Fronte, a Bogota-based fintech, has raised a pre-seed round to build a financial operating system for transnational families. The source gives no amount for the round. Rally Cap VC and Bankless Ventures co-led the round. The Base Ecosystem Fund, fintech founders, operators, and angel investors also took part. Fronte will use the money to develop Frontéalo, its household ledger and continuity engine. The system tracks recurring expenses such as rent, utilities, and education, and manages contributors across several countries. Founded by Hayden Simmons, Fronte treats the household, not the individual, as the main unit of account. It aims to turn a family's shared financial history into access to credit and other services.

Dataline raises $10.6M to give AI agents data they can trust. Dataline announced a $10.6 million funding round alongside the initial cohort of AI Data Launch partners, marking a major step toward becoming the data lifeline in the era of AI. October 31, 2026 06:58 ET | Source: DATALINE Road Town, BVI, Oct. 31, 2026 (GLOBE NEWSWIRE) - The round was co-led by Lattice and Samsung-backed Dispersion Capital, with participation from AI fund Symbolic Capital. Dataline also drew a deep bench of strategic backers spanning web2 and web3, including Coinbase Ventures, Anagram, a former Head of the CFTC, and founders and partners from Robinhood, Venmo, Anchorage, NEA, General Catalyst, Jump Capital, and FalconX. The Data Launch cohort brings together a roster of leading AI and web3 projects to establish the best data for AI, including Kite, Aerodrome, B3OS, Sentient, Sahara, Hyperliquid, Polymarket, Kalshi, Primus, Cluster, Apro, Base, Robinhood Chain, BNB, Sui, TON, and others. As part of the launch, Dataline co-announced with Base and Robinhood Chain that builders on both chains will get free Dataline access. The raise builds on early traction that has already validated demand for the network. To date, Dataline has powered 19.4 million onchain transactions with a 96.4% agent task success rate and grown a community of more than 300,000 people worldwide. The protocol was also named a winner of the 2025 BNB Chain AI Hackathon. Community participation is growing alongside network usage. Dataline's first quest with Legion drew over 1,000 unique participants, who completed over 750 quests and over 1,000 raids. Quest 2 begins October 15, providing the community with another chance of earning rewards. In November, Dataline plans to hold a Uniswap Continuous Clearing Auction (CCA) on Base and on Robinhood Chain. OpenRouter for data Autonomous AI agents are only as good as the strength of the data behind them. Dataline is the decentralized network for agent-payable data, providing a two-sided marketplace where anyone can publish a feed and any agent can pay per call with x402. Just as OpenRouter is the routing layer for AI tokens, Dataline is the routing layer for AI data. Via a single integration, every API response carries an AI confidence score weighing source reliability, freshness, and consistency, so agents can flag or refuse bad data before acting on it. Bringing more data online In addition to Dataline's curated and verified feeds, the protocol also lets anyone publish data and price it per call, like a job board for data where AI agents and humans alike can post and pick up work. A requester posts a bounty for the data they need, and any fulfiller in the network claims it, supplies the data, and gets paid. Payments settle instantly through x402, sellers' credentials never leave the gateway, and an optional zero-knowledge attestation tier lets providers attach a verifiable proof bundle to every response. Quality is enforced economically rather than by any central authority. Fulfillers stake tokens to submit their responses: good data earns the bounty, while bad data gets the stake slashed. The result is a constantly expanding marketplace of cross-verified, custom-fetched data on demand. Data is the lifeblood of AI "After building AI agents ourselves, we realized that clean and reliable data is the lifeblood of AI," said Nuo Shi, cofounder of Dataline. "Today's AI is capable enough to know what data it needs, sometimes better than we do. So we built an open network that not only delivers the most reliable data streams, but also lets AI request help to gather the data it can't reach on its own." About Dataline Dataline is the decentralized data network for AI agents, providing one integration for all markets. The protocol delivers cross-verified data sources with AI-generated confidence scores, along with a network of custom-fetched data requests to power a smarter AI workforce.
