Odaily Planet Daily reports that Solana has officially launched a subsidiary X account, "x402 on Solana," on its X platform. The account description reads, "Build solutions on Solana with internet-native x402 payment functionality."
Odaily Planet Daily reports that x402, an open-source payment protocol incubated by Coinbase and built specifically for artificial intelligence (AI) agents, is releasing a major upgrade approximately six months after its initial launch. x402 V2 essentially transforms the previously simple, one-off payment system into a mature, internet-facing unified payment layer. Version V2 includes a series of backend improvements designed to make it easier to create customizable payment processes, better wallet and identity features, and support for "traditional payment systems."
The biggest upgrade in version V2 is the unification of the x402 payment interface. x402 V2 standardizes the identification of networks and assets in the protocol, "creating a single payment format that is universally applicable across different blockchains and traditional payment systems." This means that x402 will "support multiple chains by default," supporting native tokens of other blockchains such as Base or Solana without requiring custom logic. Furthermore, the system is compatible with "traditional payment systems" such as ACH and bank card networks. The updated system also introduces a dynamic "payTo" routing function, supporting payment processes 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. (The Block)
Odaily Planet Daily reports that Cronos has officially subscribed to DoraHacks BUIDL AI, launching the x402 payment technology hackathon with a prize pool of $42,000, focusing on AI-native and agent payment applications. This move marks a strong comeback for the Cronos public chain ecosystem, leveraging its 10x lower gas, second-level block generation, and AI Agent SDK to aggressively recruit global entrepreneurs to build an AI-driven financial hub.
Following AWS and Circle, Cronos will leverage BUIDL AI's intelligent infrastructure to efficiently connect global tech enthusiasts in the intersection of PayFi and AI, accelerating ecosystem reconstruction and innovation implementation.
Odaily Planet Daily reports that Davide Crapis, head of artificial intelligence at the Ethereum Foundation, posted on the X platform that he is working with the Ethereum Foundation (EF) leadership to develop the dAI team's 2026 roadmap and thanked the growing community around ERC-8004 and x402.
According to Odaily Planet Daily, the x402 protocol garnered significant attention at the end of October, with related tokens surging and the number and volume of transactions made through the x402 protocol reaching record highs. However, this two-week-long AI narrative is now receding, with daily transaction volume plummeting by 90% from its peak.
According to x402scan data, the daily transaction volume of the x402 ecosystem peaked on November 3, reaching $2.8407 million. The daily transaction volume continued to decline thereafter, reaching only $283,600 on November 9.
At the same time, the number of new websites/servers supporting payments via the x402 protocol is also declining. At its peak, the number of new daily additions exceeded 10,000, but after November, the number of new daily additions fell to less than 2,000.
