AEON Unveils the x402 SDK V2 on BNB Chain
On November 4, 2025, AEON, a pioneering framework in crypto payments, officially released its x402 SDK Version 2 on the BNB Chain. This new software development kit allows AI agents and API service providers to seamlessly initiate and accept x402 payments within the vast ecosystem of BNB Chain. The launch marks a pivotal advancement in the operational deployment of autonomous AI transactions, effectively making blockchain transactions scalable and more efficient.
Key Features of the x402 SDK V2
The x402 SDK Version 2 comes packed with features that empower developers to integrate autonomous payment capabilities into their applications with minimal fuss. It provides a streamlined interface for AI agents and service platforms to send and receive x402-compliant payment requests, verify payment mandates, and conduct on-chain settlements, all within the BNB Chain ecosystem.
This release highlights AEON’s ambition beyond merely developing tools for AI. The organization aims to establish a robust settlement layer that connects intelligent agents with the real-world economy. This evolution paves the way for fully autonomous commerce where AI agents can independently handle transactions related to data payments and API accesses, thus interacting seamlessly with both blockchain and traditional services without the need for human oversight.
Integrated Framework for Autonomous Payments
The newly launched SDK is an extension of AEON's previous achievements, including the recently introduced x402 Facilitator on BNB Chain. This facility, developed in partnership with the BNB Chain team, is built on Coinbase's x402 payment standard, particularly designed for autonomous payments among AI entities. AEON's enhanced x402 protocol introduces improvements such as rigorous transaction verification and immutable payment receipts, enabling AI to interact with millions of service providers effectively.
Moreover, this integration ensures that AI agents can execute payments rapidly and transparently while being able to verify every transaction in real-time. These capabilities make AEON's framework an essential tool for developers looking to leverage the full potential of autonomous payments in their projects.
Recognition as a Core Builder
AEON’s commitment to building an innovative payment infrastructure has not gone unnoticed. The BNB Chain has acknowledged AEON as a critical contributor by including it in the Most Valuable Builder (MVB) Season 10 program. Out of over 500 applicants, AEON was selected to join an elite group of teams collaborating to expand the realms of AI and cryptocurrency payment infrastructure. This recognition reflects AEON's ongoing leadership in creating scalable and real-world applications for decentralized technologies.
Bridging AI and Global Commerce
AEON’s mission is to design a crypto settlement framework that bridges the gap between AI systems and global commerce. Currently, AEON connects to more than 50 million merchants globally by integrating with various local payment systems. This capability allows users to make crypto payments across different platforms seamlessly.
The rollout of the x402 SDK on BNB Chain enhances these existing functionalities, offering developers and AI systems a unified framework for autonomous payments across both digital and physical spaces. As AEON advances towards its vision, the integration of its services will likely redefine how transactions are approached within the AI landscape.
