who's really driving 402
what x 402 "basic" and "realist" are driving the development of x 402
it is time to say goodbye to these 402 "basics" and "dossys" that are driving the development of the 402 agreement。
By KarenZ, Foresight News
While AI agents are gradually becoming independent economic agents who need to buy data, call API, rent computing, etc., at the moment of its rapid development, traditional payment systems are difficult to meet these high-frequency, small, automated payment needs. It is against this background that the x402 protocol came into being。
x402 was developed by Coinbase and supported by open source payment agreements for giants such as Anthony, Amazon Web Services, Hyperbolic, Google and Cloudflare. The core function x402 is to achieve the autonomous micropayments of the AI agent by HTTP 402 status code, i.e. to allow the AI agent or software client to pay directly with USDC without the API key, to achieve the machine's autonomous settlement of the machine (M2M) and to give the AI agent a real ability to “pay”。
In thePayAI Counter-PING!x402 Eco-value anchor changesIn the paper, we discussed the contrast between PING and PayAI ' s growth momentum, which in fact reflects an important issue: x402 ecology is moving from concept to reality and from rhetoric to practice。
This post will focus on the ecological “basic” and “domain” projects. It needs to be clear that x402 ecology is still at an early stage of infrastructure development, business closure and validation, and that project selection lacks a mature reference system. It is too early to judge whether a project can run, and the key is whether the product can create real demand. And there is a need to judge the need for "frequentity" and "high frequency" to drive users and AI agents to use x 402 to complete the payment and avoid the false demand trap. And is the path to profitability clear? The long-term viability of the project。
x402 Facilitators/ Services/ Endpoints
Kite AI
Kite AI is building the "Agentic Internet" base trading layer to provide a unified identity, payment and governance infrastructure for autonomous intelligence. On 10 February 2025, Kite AI launched the Proof of AI Proof L1 sovereign block chain testing network。
Kite AI has integrated itself with x402 proxy payments standard, positioning itself as the main enforcement and settlement layer of the agreement, allowing AI agent to send, receive and reconcile payments seamlessly through standardized intent instructions。
In September 2025, Kite AI announced that it had completed a total of $33 million in financing, the most recent A round of financing, which amounted to $18 million, with the participation of PayPal Ventures and General Catallyst, which would be used to accelerate the construction of the Kite AI advanced smart body Internet. After that, Kite AI also received strategic investments from Coinbase Ventures, and the new funds will be used to support the development of its autonomous AI payment infrastructure and to work with Coinbase to accelerate the large-scale adoption of the x402 agreement。

Vistara Labs / b402
Vistara Labs is a selection project for the Binance Labs sixth quarter incubation (September 2023 - one of them, and completed the Pre-Seed Round of Finance in November 2023, with D1 Ventures and Factor taking the lead。
Vistara Labs is an Internet proxy executive. Vistara OS, its proxy Internet layer, translates passive browsing into real-time deployment, remix and returns, supported by Zara Argentina Engineering。
Vistara Labs' autonomous development plant Zara recently supported the use of x402 to achieve seamless payments between agents and the deployment of AI-driven Web3 microbusinesses (e.g., content realization)。
Vistara Labs announced on October 25, 2025 that it would take the x402 to BNB Chain by b402. b402 To support the use of all BEP-20 tokens for proxy payments, which will be achieved primarily through B402 repeaters as a credible intermediate. Most BEP-20 tokens do not perform EIP-3009 "authorization transfer" that can't process original signatures。
the current market value of the Zara token is $1.8 million, the reason for the decline in recent days or the removal of Zara from the profile of Vistara Labs。
Piverse
At the end of this month, Pieverse announced that it would launch the x402b agreement, which will be extended to BNB Chain through Pieverce Facilitator。
Specifically, Pieverse is exempt from payment by supporting EIP-3009 USDT sealing token pieUSD, and its custom-made Facilitator is able to resolve tax and audit issues by automatically generating a jurisdictional receipt during the settlement of payments and storing it immutably on BNB Greenfield。
Pieverse previously completed $7 million in strategic financing in late October, led by Animoca Brands and UOB Ventures. Pieverse was previously supported by the ninth season of the MVB。
Pieverse carried out Pre-TGE activities during the period between 16:00 and 1800 on October 29th。

Meridian (market value of tokens $2.9 million)
Meridian is a block chain project focused on x402 payment agreements designed for the AI proxy economy。
Meridian decided to use the Across to achieve its x402 protocol. According to Meridian, "When payments must be made between different EVM networks with their respective RPC configurations, Across is the best technology to achieve quick settlement between AI agents and persons trading on x402. When sent back from L2 to the Ether Workshop, there was a fraud prevention window, which may sometimes take up to seven days to settle. Meridian will use Across technology to completely bypass this fraud-prevention window to support all EVM chains and quick settlement. This method also allows agents using x 402 to pay each other in currencies other than USDC. I don't know
Meridian token MRDN market value is currently $2.9 million。
Summary
although the x402 agreement has attracted the support of many leading technology companies and encryption projects, and ecological players are expanding, x402 ecology is still in its early stages of development。
the attitude of community users towards x402 is clearly polarized, with expectations and preferences for the new paradigm of the proxy economy, as well as challenges to the maturity of the agreement, the value of its application, dispute resolution, etc。
Under the x402 road map, the x402 agreement will explore in 2026 the integration of x402 Bazaar with ERC – 80004, e-commerce refunds and hosting processes, any token support, and the concerns of Facilitator Router。
The advancement of these road map projects represents a shift from the concept of ecology to infrastructure and to application and ecological integrity. If these goals are met on schedule or over schedule in 2026, the feasibility and value of x402 as a proxy economic payment standard will be further validated and it is expected that the entire AI proxy ecology will move from the pilot phase to the commercial application phase。
