OKX's payment protocol has enabled the agent economy to take root.

Web3's initial promise was to allow value to flow as freely as information. However, for over a decade, its primary use cases have revolved around price discovery and asset trading; it has only addressed the question of "how much is this token worth," without truly answering "what can it be used for?" Meanwhile, AI has undergone a crucial leap in the past two years: from "being able to speak" to "being able to do things." Tool calls, Agent frameworks, and the MCP protocol have emerged, enabling AI to autonomously manage wallets and initiate on-chain transactions. But a new problem has arisen—when Agents become new "on-chain users" and need to collaborate with other Agent users, what "currency" do they use for transactions? What mechanism guarantees contract fulfillment? Who arbitrates when problems arise? These two threads converge on the same answer today: OKX Onchain OS released its Agent Payments Protocol (hereinafter referred to as the APP) yesterday—an open payment standard designed specifically for AI Agent business activities, and one of the most complete Agent economic infrastructures to date. What problem does the APP protocol solve? Does the term "protocol" sound a bit abstract? Let's use a concrete scenario to intuitively understand the design of the OKX APP. Recently, a certain Web3 concept track has suddenly become very popular, and you want to figure out which projects to follow as soon as possible. You've assigned this task to your transaction AI Agent (let's call it Beta). After breaking down the task, Beta discovered that to provide reliable advice, it needed three types of data: on-chain fund flows, the funding background of each project, and a security assessment of the contract code. Therefore, it released three sub-tasks on-chain, with a total budget of 50 USDG and a delivery time of 24 hours. At this point, the **APP's** guarantee mechanism was activated—50 USDG was automatically locked on-chain, ensuring the security of your payment funds. The three data agents who accepted the order also confirmed the authenticity of the payment, allowing you to start working with confidence. Five professional agents simultaneously accepted the bid, and Beta partnered with the three who first reached an agreement: the on-chain data agent was responsible for tracking fund inflows and outflows and changes in whale holdings, at a fee of 15 USDG; the funding data agent was responsible for crawling the funding rounds, investors, and valuations of each project, at a fee of 20 USDG; and the contract audit agent was responsible for scanning for code vulnerabilities and risk levels, at a fee of 15 USDG. **APP's** negotiation mechanism comes into play:** All three parties reach agreements with Beta on-chain, contracts are automatically confirmed, and each party begins working independently without any human intermediaries. 24 hours later, three sub-reports are submitted. **APP's** verification and settlement mechanism is triggered:** Beta automatically checks according to preset standards: Does the on-chain data cover all projects? Is the financing information traceable? Does the contract audit provide a clear risk rating? If all three reports pass, the three secured funds are automatically released, and the payment is credited instantly. **If any report is missing data or does not meet requirements, the funds remain locked, and **APP's** built-in dispute resolution process is automatically initiated—instead of relying solely on manual coordination or resulting in payment without receiving satisfactory deliverables. Ultimately, Beta integrates the three reports into a comprehensive analysis covering funding, fundamentals, and security, and sends it directly to you. After reviewing it, you can formulate your trading strategy based on this analysis. The entire process involves no human intervention, no invoices, no manual transfers, no need to chase tasks, and no unresolved disputes. How does the APP protocol support Agent commercialization? Previously, the payment capabilities of AI Agents were at a very rudimentary stage. Most existing protocols only addressed the basic issue of "payment," corresponding to the basic logic of the HTTP-402 protocol: simple and direct, but extremely limited. The more fundamental problem is that these solutions are designed for services built for humans, not for autonomous commercial transactions between Agents. What the APP aims to fill is precisely this gap: it's not just about enabling Agents to make payments, but about enabling Agents to confidently conduct business. And you, you only need to see the results and make decisions.

Upgrade of Business Paradigm:Compared to existing solutions, the difference in the APP lies not in a single feature, but in the different overall design logic: supporting bidirectional business relationships between Agents.

Open Business Protocol:The APP is an open protocol standard, not an exclusive product of OKX. Just like TCP/IP for the Internet, any chain, any developer, and any protocol can use this standard for construction. OKX is the initiator, but not the only participant.

Solid Underlying Logic: The APP protocol is built on the foundation of OKX OnchainOS. Before the APP was released, OnchainOS already provided complete on-chain operation capabilities for the AI ​​Agent. The APP completes the final piece of the puzzle on this basis—the commercial settlement layer between Agents. The underlying infrastructure of this system is the OKX core system, which has been running in production environments for many years: handling over 1.2 billion API calls daily, $300 million in transaction volume, response times of less than 100 milliseconds, and a system availability of 99.9%. For AI agents, the stability of the infrastructure directly determines whether the agent can reliably fulfill its business commitments. This is especially crucial for autonomous agents. Why Leading Institutions Quickly Responded and Joined: On the day of the APP's release, partners from the public blockchain, data infrastructure, DeFi protocol, and cloud computing fields successively announced their support. Their evaluations also defined the APP's value from different dimensions. Solana: The APP is the preferred settlement layer for AI Agent payments. Solana, a public blockchain known for its high performance, stated that the APP significantly expands Agent payment capabilities from single payments to a complete business loop, positioning itself as the default settlement layer for AI Agent payments—this reflects Solana's long-term strategy for high-frequency, low-latency on-chain settlement scenarios. Ethereum Foundation: Open Standards are the Way to Scalable Ethereum is currently the world's largest smart contract platform, supporting the vast majority of mainstream Web3 applications. As the first-day partner of the app, the Ethereum Foundation stated, "Open standards are the way to scale all of this," expressing its recognition of the entire open protocol ecosystem and aligning perfectly with the app's positioning as a cross-chain open standard.

Optimism：APPThe real breakthrough is the complete business process

Optimism is one of the most important Layer 2 scaling solutions for Ethereum. Its evaluation of APPs goes straight to the core: "The real breakthrough is not that the Agent can make payments, but that the Agent can run a complete business process. Open standards are the way to scale all of this."
