According to official news, ENS v2 will be deployed directly on the Ethereum mainnet and will cease the development of its proprietary Layer 2 network Namechain.This decision stems from the Ethereum L1 scaling speed exceeding expectations. After the Fusaka upgrade in 2025, which will raise the Gas limit to 60 million, the Gas cost for ENS registrations has decreased by 99% over the past year, with the average registration fee now below $0.05. Nick.eth stated that although the development of Namechain will stop, the roadmap for ENS v2 remains unchanged, and users will still experience features such as one-step registration, support for cross-chain stablecoin payments, and a completely new registry design.The ENS team believes that staying on L1 can eliminate the additional trust assumptions brought by L2 and leverage Ethereum's strongest infrastructure guarantees. Currently, the brand new ENS App and ENS Explorer have entered public Alpha testing.

The game blockchain Ronin announced that the Saigon testnet has completed its migration to Ethereum, and the mainnet migration to Ethereum L2 is proceeding as planned, expected to be completed between the first and second quarters of 2026.

BNB Chain announced on platform X that the "AI Agent Economy" has launched on BNB Chain, and the ERC-8004 infrastructure has been deployed on the BSC mainnet and testnet.This standard aims to establish a trust layer for AI agents by introducing two core components: identity registration and reputation registration, providing verifiable on-chain identity and reputation systems for autonomously operating AI agents.

The Saigon testnet of the Ronin chain will migrate to the Ethereum mainnet this Thursday, marking Ronin's return to Ethereum and an upgrade to Layer 2.The hard fork is scheduled to occur at block height 45528550 (February 5, 2026, 23:58:55 UTC), at which point the testnet chain ID will also be updated to 202601. After the mainnet migration to Ethereum, the mainnet chain ID will remain unchanged.

According to The Block, the crypto computing network Arcium has launched its mainnet Alpha version on Solana, marking the transition of its crypto computing network from a testing environment to early production use infrastructure.The project aims to power the crypto capital markets on public blockchains, with its execution engine allowing developers to build verifiable and composable applications while keeping data fully encrypted. The first application to go live on the network, Umbra, launched its "private mainnet" simultaneously, building a shielded financial layer on Solana through a phased rollout, initially offering shielded transfers and crypto exchange functionalities. Access will be limited at first, with 100 users opening each week and a deposit limit of $500, with plans to expand access and raise limits in February.

According to the official announcement, Lido V3 has launched on the Ethereum mainnet, introducing the stVaults modular staking infrastructure supported by stETH, designed specifically for developers.This upgrade expands the Lido protocol from a single pooled liquid staking (Lido Core) to support diverse staking models while retaining the shared liquidity and DeFi composability of stETH. stVaults allow builders to customize staking settings without having to build the infrastructure from scratch.

Ethereum Foundation AI lead Davide Crapis announced that ERC-8004 has been launched on the Ethereum mainnet. The team will deploy the singleton to all major L2s in the coming weeks.The ERC-8004 standard enables a discovery mechanism and portable reputation, allowing AI agents to interact across different organizations, ensuring that reputation circulates everywhere, thus unlocking a global AI service interoperability market.

The Bitcoin ZK-rollup project Citrea, backed by Founders Fund and Galaxy Ventures, has officially launched its mainnet, introducing DeFi lending, structured products, and the native USD stablecoin ctUSD, which uses BTC as collateral, aiming to bring "idle Bitcoin" into a complete DeFi and payment system.Citrea stated that the active DeFi liquidity at the initial stage of the mainnet launch is expected to reach $50 million. ctUSD is issued by MoonPay, pegged 1:1 to cash and short-term U.S. Treasury bonds, and is not a cross-chain asset but is natively issued on Citrea to reduce bridging risks and avoid liquidity fragmentation. The project has also sparked controversy: as block subsidies decline, should Bitcoin miner fee income be supported through non-payment uses like DeFi and stablecoins? Supporters argue that this is a sustainable source of demand, while opponents emphasize that Bitcoin block space should focus on simple, censorship-resistant payments.It is noteworthy that during the Citrea testnet phase, data availability usage once accounted for nearly 10% of Bitcoin's monthly data bandwidth, indicating that Rollup could have a substantial impact on Bitcoin's block space.

Solayer announced that its mainnet data has officially launched on the data analysis platform Databricks, aiming to provide users with a fully transparent data access experience from blockchain to dashboard. Through this integration, users can access real-time insights and daily data updates from Solayer, and further explore in-depth information including historical archival data from InfiniSVM.

A smart contract standard for trustless AI Agent communication on Ethereum, ERC-8004, is set to be officially deployed to the Ethereum mainnet this Thursday. Marco De Rossi, head of MetaMask AI, stated in a developer Telegram group that further development of ERC-8004 has been "frozen," with plans to launch on the mainnet mid-week. The official Ethereum X account later confirmed that the protocol will be "live soon" on the mainnet.ERC-8004 (Ethereum Request for Comment) proposes a standardized way to register and verify AI Agents on-chain, allowing developers to integrate it directly into smart contracts without needing to upgrade the Ethereum network itself. The standard aims to address two core issues in the AI Agent economy: first, how to discover AI Agents in an open environment, and second, how to assess their trustworthiness. By introducing portable reputation and discovery mechanisms, ERC-8004 enables cross-organizational AI Agents to interact without the need for prior trust, thus supporting an open Agent economy.Davide Crapis, head of AI at the Ethereum Foundation, stated that Ethereum has unique platform conditions to "secure and settle AI-to-AI interactions." Developers also revealed that the standard will support Ethereum Layer 2 networks like Base in the future. With the launch of ERC-8004, AI Agents are expected to evolve from isolated tools into on-chain participants with autonomous economic behavior, laying the foundation for a decentralized AI service market.

The zero-knowledge proof public chain Aleo announced that its privacy stablecoin USDCx has been launched on the mainnet, which is based on Circle's xReserve. USDCx is aimed at institutional users and is primarily used for scenarios such as payroll, settlement, and vendor payments. Mainnet launch partners include Toku, Request Finance, Dynamic, Blockdaemon, Chainalysis, and others.

The Ethereum official announced that the ERC-8004 standard is about to go live on the mainnet. By enabling a discovery mechanism and portable reputation, ERC-8004 allows AI agents to interact across different organizations, ensuring that reputation circulates everywhere, thus unlocking a global AI service interoperability market.

AI payment public chain Kite has released its mainnet roadmap, aiming to create a trust and payment technology stack native to intelligent agents, addressing the bottlenecks of trust, authorization, and payment in the transition of AI agents from "answering questions" to "executing tasks."The roadmap clarifies the native compatibility of the x402 protocol, supporting standardized payment intentions and settlement with pay-per-call and end-to-end audit capabilities. It also breaks down system capabilities into six independent pillars: agent trustworthiness (KitePass identity anchor + programmable governance), agent settlement (native stablecoin + Facilitator component), agent developer infrastructure (zero-fee RPC + documentation + observability tools), agent network operations (external validators + VaaS + gradual decentralization), AgenticFi (DEX + LSD + cross-chain bridging + deposit and withdrawal channels), and agent ecosystem growth engine (incentive systems + ecological events). Kite stated that the mainnet will adopt a gradual rollout, with phased deliveries over one to two years, prioritizing a balance of security, auditability, and ecological scalability, ultimately forming a sustainable intelligent agent economic system.It is reported that Kite previously completed a $33 million financing round led by PayPal Ventures and General Catalyst, and received strategic investment from Coinbase Ventures.

According to market news, the Bitcoin Layer 2 project Citrea, supported by Founders Fund and Galaxy, has officially launched its mainnet and introduced the native stablecoin ctUSD backed by M0 infrastructure.Citrea uses zkEVM to process transactions and writes zero-knowledge proofs onto the Bitcoin main chain, supporting financial applications such as BTC collateralized lending and structured products, with the goal of building a native Bitcoin financial market.
