first_img Brave releases BAT roadmap 4.0, introducing a new unified wallet and stablecoin payment protocol

According to the official blog, Brave officially released the Basic Attention Token (BAT) roadmap 4.0 on July 9. This update aims to address the new challenges brought by artificial intelligence and a cashless economy, fully integrating BAT, Brave Rewards, and Brave Creators into a transactional attention economy. The core initiatives of the roadmap include the launch of a new unified version of Brave Wallet that integrates traditional payment methods with self-custodied crypto assets, as well as the construction of a privacy payment protocol layer, BravePay, based on stablecoins, thereby providing foundational support for autonomous agent payment features such as x402 and Machine Payment Protocol (MPP) within the browser.In addition, the roadmap also plans several new products to expand the ecological boundaries. Brave plans to launch virtual and physical payment cards for Brave Rewards that support daily consumption and return BAT rewards, while also developing a new creator contribution protocol to ensure that creators receive micro-royalty compensation when their content is utilized by AI products. In terms of token economics, a portion of the net income generated from Brave Wallet's revenue features, payment cards, and the BravePay protocol will be directly used to repurchase BAT to support user rewards and ecological growth. With the advancement of the above new features, Brave will gradually phase out traditional advertising notification units by the end of 2026 and fully shift the user reward mechanism towards personalized offer walls and a new loyalty program.

Uniswap initiates a temperature check for the activation of v4 protocol fees, introducing a tiered fee controller system

According to official news, Uniswap Labs has released a temperature check proposal, suggesting the activation of protocol fees in the v4 pool. This proposal follows the rapid governance process previously approved by UNIfication and will directly enter a five-day Snapshot voting period, followed by on-chain voting.Due to the Hook architecture of v4 making fee settings more complex than v2/v3, the proposal has designed the V4 Fee Controller system, which includes two core contracts: V4FeePolicy calculates the fees for any pool based on governance rules, and V4FeeAdapter is responsible for executing governance overrides and collecting fees into TokenJar. Fees are calculated hierarchically based on the family of the pool: first checking the specific trading pair rate set by governance, then the family default rate, and finally the global default rate.This proposal aims to activate fees for three types of pool families across 11 chains including Ethereum, Arbitrum, Base, and BNB Chain: static rate pools without Hooks, CCA pools after continuous liquidation auctions, and aggregator Hook pools. The rates for aggregator Hook pools are adjusted by a 25x multiplier, with a default of 10 bp for non-Base chains (3 bp for stablecoin pairs) and a default of 3 bp for Base chains (1 bp for stablecoin pairs). All fees will flow into each chain's TokenJar, and the amount of UNI burned on L2 and Alt-L1 will be cross-chain bridged to the Ethereum mainnet and sent to the 0xdead address.The Snapshot voting window is from July 7 to July 12, and on-chain voting will start during the week of July 13. Since GovernorBravo limits each proposal to 10 actions, two on-chain votes will be submitted in parallel to cover all chains.

first_img Key components surge in price, PC brands accelerate the introduction of domestic storage from Changchun and Changxin to reduce costs

According to the Industrial and Commercial Times, due to the soaring prices of key components such as memory and SSDs, the cost pressure for configuring high-capacity storage in mainstream laptops has greatly increased. Cost-effective mainland Chinese memory and storage components are gradually penetrating the PC supply chain, with brands such as Lenovo, ASUS, MSI, Gigabyte, Acer, and even the American brand Apple accelerating the certification, introduction, or platform tuning of related products.The report pointed out that Lenovo has expanded its use of mainland components this year, and recently flagship laptop models equipped with Yangtze Memory Technologies (YMTC) SSDs have appeared on North American cross-border e-commerce platforms. The American brand Apple is also reported to be negotiating with the U.S. government to procure Changxin Memory Technologies (CXMT) memory to cope with the rising prices. In terms of Taiwanese board manufacturers, MSI recently announced that it is the first to complete the verification and tuning of Changxin Memory DDR5 chips on the AMD platform at DDR5-8000+, while Gigabyte has also adopted Changxin Memory chips in some motherboard models. ASUS and Acer have introduced memory modules from mainland manufacturers such as BIWIN through their own brand memory certification or OEM models.Industry analysts believe that although the short-term imbalance in supply and demand for storage has prompted non-mainland brands to accelerate related certifications, due to the limited production capacity of mainland manufacturers, brand Taiwanese manufacturers still emphasize that Korean original manufacturers with long-term contracts remain the main supply partners at present.

The Korea Exchange has introduced new regulations: companies listed under technical exceptions that transition to businesses such as "cryptocurrency asset investment" will face delisting reviews

According to the Korea Exchange (KRX) announcement on July 2, to further improve the KOSDAQ market system, KRX has officially revised the relevant listing rules and implementation details, aiming to strictly control the deviation of technology special listing companies from their main business.The new regulations clearly state that companies listed through technology exceptions that change their main business direction within 5 years after listing (excluding businesses similar to or subsidiary to the original main business) will be subject to substantial delisting review. KRX officials specifically cited an example where a related biotechnology company transferred its management rights to an overseas digital asset company after listing last year and illegally transformed into a "cryptocurrency vault" and other digital asset professional investment institutions. KRX emphasized that such behavior has caused the company to deviate from the technical and growth assessment basis approved at the time of listing, and therefore must undergo strict delisting review.In addition, the new regulations have added additional restrictions to the grace period for delisting conditions enjoyed by special listing companies (i.e., exemption from revenue insufficiency or large-scale losses within 3 to 5 years), requiring relevant companies to publicly disclose their "corporate value enhancement plans" during this period to ensure future growth and strengthen communication with investors. This revision of regulations also includes measures to optimize the capital market, such as expanding customized qualitative review standards for innovative companies and establishing a low PBR (price-to-book ratio) company disclosure system.
