Original Authors: Mao Jiehao, Liu Fuqi Introduction: From HTTP 402 to the Dawn of the Machine Economy In 1996, the designers of the HTTP protocol reserved the "402 Payment Required" status code, but due to the lack of supporting payment infrastructure, it became the "ghost code" of the Internet era. Thirty years later, the x402 protocol, initiated and promoted by Coinbase, has awakened this dormant status code into a "digital cash register" for AI autonomous transactions. When meteorological AI robots automatically purchase global weather data and self-driving cars pay road tolls in real time, the traditional payment logic of "account opening-authentication-authorization" is being dismantled—x402, through the closed loop of "HTTP request-402 response-on-chain payment-service delivery," has, for the first time, enabled atomic transactions between machines without human intervention. Behind this transformation is the rise of the "machine economy"

The largest dark pool decentralized exchange (DEX) by trading volume in the Solana ecosystem, HumidiFi, has officially launched the first community sale (ICO) of its governance token WET. The sale will begin on December 3 on Jupiter’s decentralized token launch platform DTF and will be conducted in three rounds on a first-come, first-served basis. The total sale accounts for 10% of the total token supply (100 million WET), with an initial fully diluted valuation (FDV) ranging from $50 million to $69 million. As background, HumidiFi’s 24-hour trading volume has reached as high as $1.048 billion, accounting for about 30% of the total DEX trading volume on the Solana chain. Its unique “dark pool” mechanism provides MEV protection and a trading experience with lower slippage. This ICO is not only a major milestone in HumidiFi’s own development but is also seen as the next indicator for gauging the market enthusiasm of the Solana DeFi ecosystem.

According to Deep Tide TechFlow news, OpenMind and Circle announced a strategic partnership to jointly develop the first payment infrastructure for autonomous, real-world embodied AI trading.

Robots gradually becoming independent economic entities will participate in three core markets: 1. Task Market: Bots perform delivery, inspection, and other tasks to earn rewards. 2. Information Market: Local sensor data and environmental state summaries can be sold to agents responsible for decision-making and planning. 3. Resource Market: Bots provide resources for charging, storage, and tool usage.

The ruling Democratic Party of Korea has issued an ultimatum to financial authorities, urging them to accelerate the formulation of local stablecoin market-related laws. The ruling party has notified the country's Financial Service Commission, requesting the submission of a government proposal on stablecoin regulation by December 10, referring to it as the final demand.

According to Mars Finance, the financial stability review preview released by the European Central Bank today (the official report will be published on Wednesday) shows that by 2025, the total market capitalization of stablecoins will exceed 280 billion USD, accounting for about 8% of the entire crypto market. Among them, USDT and USDC together account for nearly 90%, with reserve assets reaching the scale of the top 20 global money market funds. The European Central Bank's report points out that if stablecoins are widely adopted, it may lead households to convert some bank deposits into stablecoin holdings, weakening banks' retail funding sources and increasing financing fluctuations. Although MiCAR has prohibited European issuers from paying interest to curb such transfers, banks are still calling for similar restrictions to be implemented in the U.S. In addition, the rapid rise of stablecoins and their connection to the banking system may also trigger a concentration of fund withdrawals during crises. The report emphasizes the risks of cross-border "multi-issuance mechanisms," warning that EU issuers may struggle to meet global redemption.
