Innovation continues unabated amidst the Web3 development wave. On December 19th, the x402 Builders Meetup, an industry conference focusing on the x402 ecosystem, successfully concluded at the Frontier Tower. Hundreds of developers and builders from the AI and Crypto fields gathered to discuss the development of the x402 ecosystem. MiniDoge, a leading Web3 ecosystem project, was invited to attend and deliver a speech, detailing its strategic layout in “DeFi + DePIN + AI public chain,” analyzing the path to realizing Web3 value under the x402 protocol, and injecting momentum into ecosystem collaboration and innovation.

The x402 protocol enables “internet-native payment” and optimizes the MiniDoge ecosystem

“402” is a reserved status code in the native HTTP standard (similar to 401 meaning unauthorized and requiring authentication, and 404 meaning the requested resource does not exist), indicating that a service requires payment but has been idle for a long time. In May 2025, Coinbase officially activated this standard, hoping to create an “internet-native payment” experience.

Previously, online payments required account registration, filling out forms, and linking credit cards, and could also involve high transaction fees and regional restrictions. The x402 protocol, however, eliminates the need for registration and card linking, supports pay-per-transaction transactions in stablecoins like USDC, and unlocks resources instantly after payment. This perfectly matches the needs of high-frequency, small-amount automated transactions and AI-driven payment in Web3/AI scenarios. This innovation breaks down the cumbersome framework of traditional online payments, greatly promoting the development of the Web3 ecosystem and driving the free flow of information and value.

MiniDoge and the x402 protocol form a highly complementary and mutually empowering relationship: As an ecosystem project integrating “DeFi + DePIN + AI public chain”, MiniDoge can leverage the x402 protocol to achieve instant micro-payments for MemeNFT, AI agent arbitrage, and real-time settlement through distributed computing on the DePIN network, accelerating its transformation from entertainment attributes to practical value; while MiniDoge’s DePIN physical device network and community user base can also provide terminal node support and traffic empowerment for the x402 protocol, helping the protocol break through the technology circle to reach a wider range of C-end users, forming a virtuous cycle of complementary functions and co-construction of scenarios.

The x402 offline gathering attracted attention, and MiniDoge’s speech received industry recognition

This x402 Builders Meetup, hosted by BitsLab, a company focused on Web3 ecosystem security, and co-organized by AEON, CipherOwl, LangrenusFund, and other organizations, was one of the most important offline gatherings for the x402 protocol before Christmas. The event was held at the Frontier Tower in San Francisco, a hub for the robust Web3 ecosystem. The conference focused deeply on the future development of the x402 protocol, attracting hundreds of developers and builders from the AI and Web3 fields. They engaged in in-depth discussions on topics such as the future of Micro-payment agent economies, x402 ecosystem infrastructure construction, and the path to improving Web3 payments, resulting in a lively exchange of ideas and generating widespread attention on social media platforms like X.

MiniDoge was invited to attend and deliver a keynote speech, systematically dissecting the ecosystem logic of “DeFi + DePIN + AI public chain,” discussing how the x402 protocol promotes the realization of Web3 value, and sharing its project plan for 2026, which garnered attention and resonance from the audience. During the event, MiniDoge also engaged in in-depth exchanges with several developers, payment companies, and investment institutions on DePIN hardware integration and AI agent payment scenario innovation, reaching several cooperation intentions. This participation not only strengthened MiniDoge’s interaction with the San Francisco crypto community and deepened its recognition in core technology circles, but also propelled the project from a community-driven model to a global ecosystem leader, injecting high-quality resources for subsequent technology integration and scenario implementation.

Web3 development is ushering in a new wave, and MiniDoge demonstrates its ecosystem resilience

In 2025, Web3 development ushered in a new wave, with a full-scale explosion of technological integration and application scenarios, propelling the industry towards “product innovation + ecosystem collaboration + value realization.” AI technology is increasingly being applied in Web3, moving beyond mere concepts to practical applications such as on-chain smart contract auditing, real-time risk warnings, and personalized NFT generation, significantly lowering the barrier to entry for Web3. The emergence of the x402 protocol filled the gap in AI-assisted payments; its low latency and high throughput meet emerging demands such as machine-to-machine micropayments and API call billing, becoming a crucial support for the integration of AI and encryption technologies. On the hardware front, the Doubao AI phone, a collaboration between ByteDance and ZTE, sold out on its first day of launch, generating significant online buzz. Various Web3 consumer hardware products also emerged rapidly, bringing Web3 applications closer to everyday life. Furthermore, the large-scale implementation of DePIN technology has deeply integrated blockchain with real-world physical infrastructure, and the advancement of RWA compliance has broadened the value-carrying boundaries of Web3. Coupled with the technological and resource support of giants like Coinbase, the practical application process of the entire industry has accelerated significantly.

Facing new industry trends, MiniDoge has made solid preparations around technology implementation and practical value. Technologically, it promotes the integrated innovation of “DeFi + DePIN + AI” to foster ecosystem development; it is planning to proactively connect to the x402 protocol to enable smoother small-amount payments via MemeNFT and computing power settlement on the DePIN network. In terms of physical implementation, the MiniDoge blockchain phone, similar to the Doubao AI phone, possesses stronger Web3 ecosystem attributes and continues the core logic of “mining while using.” Users can contribute computing power to the DePIN network simply by using their phones. The phone also features a built-in multi-chain wallet and on-chain data visualization functions, making it easy for ordinary users to use. In terms of ecosystem building, MiniDoge supports multi-chain transactions through MiniDogeSwap to improve capital circulation efficiency and actively participates in events such as Art Basel Miami Beach to extend and empower NFT culture, transforming the project from a mere cultural symbol into an ecosystem project with practical technological support and application scenarios, thus possessing stronger ecosystem resilience throughout industry cycles.

Future Outlook: Leveraging the momentum of the x402, MiniDoge accelerates global value accumulation

This x402 Builders Meetup marks a key step in MiniDoge’s global expansion and ecosystem upgrade. Looking back at 2025, from sponsoring the Orbis86 Venture Summit at San Francisco Tech Week and shining at TechCrunchDisrupt with Worldcoin, to its art crossover at Art Basel Miami Beach, and now its deep involvement in the x402 ecosystem gathering, MiniDoge continues to deepen its presence in the European and American markets, constantly expanding its industry resources and cooperation boundaries.

In the future, MiniDoge will advance the mass production of Web3 smartphones, integrating support from multiple chains such as Polygon and Arbitrum. Simultaneously, leveraging the technological potential of the x402 protocol, it will deepen cooperation and further explore innovative scenarios such as AI-assisted payment and DePIN hardware settlement. With the establishment of its New York office, the progress of its university exchange tour, and in-depth cooperation with global art IPs and technology institutions, MiniDoge’s “culture + technology + physical” ecosystem model is unleashing even greater potential. MiniDoge will steadily grow from an innovator in the meme space to a leader in the Web3 industry ecosystem, releasing greater value in the wave of AI and Web3 convergence.
