AEON wants to make it possible for AI agents to do more than just think—they should also be able to pay.
The blockchain payment framework today released its x402 SDK Version 2 on BNB Chain, marking a major advance in the development of autonomous AI-to-AI transactions. The SDK enables AI agents and API service providers to initiate and accept x402 payments natively within BNB Chain’s scalable ecosystem.

In plain terms, AEON’s update means autonomous digital entities—AI agents, bots, and API-driven services—can now handle secure, on-chain payments without human intervention.

Developers can access the SDK and documentation via AEON’s GitHub repository

Empowering Developers to Build Payment-Aware AI

The updated x402 SDK is designed for simplicity. Developers can embed payment logic directly into AI systems or API services with minimal setup, allowing these systems to send and receive x402-compliant payment requests, verify permissions, and settle transactions autonomously through the AEON x402 Facilitator on BNB Chain.

AEON’s broader goal is ambitious: to become the settlement layer connecting AI to the global economy. In practice, that means AI models could one day pay for APIs, access premium datasets, or settle digital contracts without human involvement—a key step toward machine-to-machine (M2M) commerce.

“AEON isn’t just building tools for AI—it’s building the infrastructure for autonomous economic interaction,” said a spokesperson for the project.

Integrating With BNB Chain: Scale Meets Intelligence

The SDK launch builds on AEON’s earlier integration of the x402 Facilitator protocol with BNB Chain, developed in collaboration with Binance’s blockchain team.

The x402 standard—originating from Coinbase’s open payments specification—enables trustless, on-chain payments between autonomous systems. AEON’s version extends this protocol with enhanced transaction verification, immutable receipts, and native settlement support, unlocking real-time, auditable payments across millions of BNB Chain service endpoints.

In effect, AEON is operationalizing AI-native payments on one of the world’s most widely used blockchains—bridging Coinbase’s Web3 payment vision with Binance’s infrastructure scale.

Recognized as a Core Builder by BNB Chain

AEON’s momentum hasn’t gone unnoticed. The company was recently named a participant in BNB Chain’s Most Valuable Builder (MVB) Season 10 program, selected from more than 500 applicants.

The recognition cements AEON’s position among a select cohort of teams helping shape the next wave of crypto payment infrastructure, particularly at the intersection of AI and blockchain interoperability.

The Bigger Picture: AI Meets On-Chain Liquidity

AEON’s infrastructure already connects to 50+ million merchants worldwide, thanks to integrations with QR Ph (Philippines) and Pix (Brazil)—two of the most successful local payment standards. With its SDK now live on BNB Chain, AEON extends that reach into the developer and AI community, giving machine-driven systems access to both digital liquidity and real-world payment rails.

In doing so, AEON joins a fast-emerging frontier where AI systems don’t just compute—they transact.
Other projects, such as Fetch.ai and SingularityNET, have explored similar ideas, but AEON’s x402 implementation may be one of the first to offer a production-ready settlement framework with global reach and compliance alignment.

Why It Matters

The promise of autonomous finance hinges on infrastructure that’s both smart and verifiable. AEON’s x402 SDK on BNB Chain provides a blueprint for how AI, blockchain, and payments can converge to support intelligent economic agents that interact in real time—without banks, middlemen, or manual oversight.

If successful, AEON could play a foundational role in building the payment backbone for AI-driven economies, where machines securely buy, sell, and trade digital services around the clock.
