AEON raised $8m led by YZi Labs to build an AI-native settlement layer, using its x402 protocol on BNB Chain to let agents pay 50m+ merchants via on-chain receipts.
Summary
- AEON, an AI-native payment and settlement layer, has raised $8 million in a pre-seed round led by YZi Labs, with IDG Capital, HashKey Capital, Stanford Blockchain Builders Fund, and Oak Grove Ventures also participating.
- The project is building settlement infrastructure for value exchange between AI agents and has already launched an AI payment product that lets agents interact with over 50 million physical merchants worldwide.
- AEON has partnered with BNB Chain to deploy its x402 Facilitator, turning the long-dormant “402 Payment Required” status code into a verifiable, on-chain settlement rail for AI-to-merchant transactions.
AEON has completed an $8 million pre-seed funding round to build what it calls the “financial foundation of the AI economy,” with Binance venture arm YZi Labs leading the round alongside IDG Capital, HashKey Capital, Stanford Blockchain Builders Fund, Oak Grove Ventures, and other backers. According to a ChainCatcher-summary of reporting from The Block, the company did not disclose its valuation, but said the capital will be used to develop settlement infrastructure that allows autonomous AI agents to exchange value directly with each other and with real-world merchants.
YZi Labs backs “financial foundation of the AI economy”
In a statement cited in KuCoin’s flash update, AEON said the goal is to create an AI-native payments fabric that supports “high-frequency microtransactions, on-chain agent identity, and global fiat settlement” so that AI systems can plug into commerce without human intermediaries. PANews added that the team is explicitly targeting the “agentic economy,” positioning the protocol as a back-end layer that can be embedded into AI assistants, bots, and services that need to pay for APIs, subscriptions, or real-world goods.
AEON launched its first AI payment product in May, enabling AI agents to connect with more than 50 million physical merchants globally through integrations with existing payments partners. The company claims this lets agents route payments at point of sale, handle subscriptions, and settle online transactions while abstracting away blockchain complexity from end users and merchants.
x402 turns HTTP into an on-chain payment rail
A key part of AEON’s stack is its x402 protocol, which repurposes the long-ignored “402 Payment Required” HTTP status code into a programmable payment step for AI agents executing web-based actions. In an earlier press release, the company explained that x402 allows agents to “independently execute online transactions by embedding payments directly into standard HTTP interactions,” so that an agent can receive a 402 response, pay in stablecoins, and unlock access with no human in the loop.
Built on top of that protocol, the newly announced x402 Facilitator is deployed natively on BNB Chain and adds verifiable transactions, on-chain settlement, and immutable receipts to each agent-driven payment. Every x402 transaction is validated by the Facilitator for “payload authenticity and mandate compliance” before being finalized on BNB Chain, generating a tamper-proof on-chain receipt that includes the agent’s ERC-8004-compliant identity for auditing and reconciliation.
AEON says the BNB Chain integration gives its system the scalability and transparency needed for production-level AI-to-merchant commerce, allowing agents to interact with “millions of service providers across the BNB ecosystem” and execute payments that are “fast, transparent, and verifiable in real time.” Combined with the fresh $8 million round led by YZi Labs, the launch signals growing institutional conviction that an agent-specific settlement layer will be a core piece of infrastructure as AI systems start to transact on behalf of users and enterprises.
