v2

The on-chain derivatives protocol MYX has announced the completion of a strategic financing round led by Consensys, with participation from Consensys Mesh and Systemic Ventures. Following this round of financing, Consensys officially becomes MYX's largest investor, and the funds will be used to support the release of MYX V2 and the deployment of a modular derivatives settlement engine.MYX V2 marks the platform's transition from a vertically integrated DApp to a modular settlement layer, allowing other products and platforms to build on top of it. This design aims to prevent the fragmentation of derivatives liquidity across chains and promote the industry's evolution from isolated DEXs to shared clearing and settlement primitives. At the protocol level, MYX V2 integrates account abstraction based on EIP-4337 and EIP-7702, combined with Chainlink's latest permissionless oracle stack, to address long-standing pain points such as slow onboarding of long-tail assets, low capital utilization efficiency, and complex trading processes.

According to the official announcement, Bitcoin Core v29.3 has been officially released, and users can download it from the official website.

Vitalik commented on "ENS stops L2 Namechain development, v2 will be directly deployed on the Ethereum mainnet": "This is a wise decision. ENS domain names and records are the core state of the Ethereum ecosystem. I believe the best architecture for decentralized identity and social (which I think ENS is in this domain) is to store each user's account and profile data on L1, and use a dedicated L2 (which could be much simpler than a full EVM) to handle user operations (e.g., actions on social platforms)."

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.

According to the official announcement, SUN.io has completed the update and deployment of the V2 routing contract, and the new contract is officially online. The official recommends prioritizing the use of the latest contract address for integration, while this update does not involve any adjustments to the energy subsidy policy. Both the old and new contracts continue to enjoy a maximum energy subsidy of 99%, and other rules remain unchanged.It is reported that SUN.io is the core DeFi infrastructure of the TRON ecosystem, focusing on decentralized trading and liquidity services, covering token exchange, liquidity management, and more, dedicated to providing users and developers with an efficient, low-cost, and secure on-chain trading experience.

Trust Wallet posted on platform X that it is collaborating with Binance to provide a fast verification pathway for a specific group of users affected by the browser extension v2.68 incident, in order to simplify and expedite the compensation process.Binance.com users who deposited funds into the stolen wallet from their Binance accounts before December 24, 2025, can confirm ownership using their Binance accounts. Eligible affected users will receive an email notification from the Trust Wallet support team and will need to submit a verification video as instructed. Users who do not meet the fast verification criteria will continue with the original compensation process.

According to the official announcement, SUN.io has completed the upgrade of the smart routing contract and the V2 routing contract. Without changing the way the contract interface is called, energy subsidy resources will be concentrated in the core contract to enhance overall trading performance and resource utilization efficiency.At the same time, starting from December 30, 2025 (Singapore time), the upgraded new contract will continue to enjoy a maximum of 99% energy subsidy; the replaced old contract will stop subsidies from January 14, 2026, 23:59:59 (Singapore time), while other business-related contract policies will remain unchanged. This upgrade does not affect users' normal usage.

According to The Block, the open-source payment protocol x402, incubated by Coinbase and designed for artificial intelligence (AI) agents, is launching a major upgrade approximately six months after its release.x402 V2 essentially transforms the originally simple single-call payment system into a mature, internet-facing unified payment layer. The V2 version includes a series of backend improvements aimed at making it easier to create customizable payment flows, better wallet and identity features, and support for "traditional payment systems."The biggest upgrade in V2 is the unification of x402's payment interface. x402 V2 standardizes the way networks and assets are identified within the protocol, "creating a single payment format that can be used across different blockchains and traditional payment systems." This means that x402 will "natively support multiple chains" by being able to support native tokens from other blockchains like Base or Solana without the need for custom logic. Additionally, the system is also compatible with "traditional payment systems" such as ACH and card networks.The updated system also introduces a dynamic "payTo" routing feature that supports payment flows such as usage-based billing, subscriptions, prepaid payments, and multi-step transactions. Developers can also inject "lifecycle hooks" for conditional tools or metric monitoring, and create more customized payment walls.

Gnosis will continue to closely monitor the situation and will provide updates as more information becomes available."

Flashbots Strategic Director and Lido Strategic Advisor Hasu stated, "Balancer v2 was launched in 2021 and has since become one of the most watched and frequently forked smart contracts. This is very concerning. Whenever a contract that has been live for such a long time is attacked, it (rightfully) sets back the adoption of DeFi by 6 to 12 months."AI

The Berachain Foundation stated, "The validator nodes have coordinated to pause the Berachain network to allow the core team to execute an emergency hard fork to address the vulnerability issues related to Balancer V2 on BEX.
