Crypto exchange OKX has announced the launch of the Agent Payments Protocol (APP), an innovative open standard aimed at empowering artificial intelligence agents to conduct complete business transactions across various blockchain networks without the need for human intervention. This groundbreaking protocol, unveiled on April 29, marks a significant evolution beyond the mere execution of simple payments. It enables AI agents to oversee a spectrum of commercial activities, including pricing, negotiation, escrow, settlement, and dispute resolution.
Historically, existing agentic payment systems were limited to executing single payments based on one-time requests. In contrast, OKX emphasizes that the APP facilitates the management of comprehensive business relationships and transaction lifecycles. The transition, as noted by OKX, has seen AI agents evolve from merely responding to inquiries to autonomously managing workflows and business processes on behalf of users. This shift has led to a new bottleneck in commerce, transitioning from intelligence to executing business transactions in their entirety.
OKX CEO Star Xu characterized this initiative as a pivotal move towards real-world implementation of what he termed the “Agent economy.” The APP is constructed as an open standard that operates across multiple blockchain platforms, with notable mentions of Solana and Ethereum as key participants in the initial phase of deployment.
At its core, the protocol features a Payment Software Development Kit (SDK), allowing developers to seamlessly integrate one-time payments, batch transactions, and usage-based payments using OKX’s X Layer infrastructure. Notably, transactions utilizing this infrastructure can incur zero or minimal gas fees. Furthermore, the APP is designed to work alongside OKX’s self-custodial Agentic Wallet, which was launched earlier in March and is capable of functioning across more than 20 blockchain networks using trusted execution environments.
The rollout of the Agent Payments Protocol has garnered support from several major technology and blockchain enterprises. Amazon Web Services, Alibaba Cloud, Uniswap, Paxos, and QuickNode have all voiced their commitment to participating in this initiative, alongside key blockchain ecosystems like the Ethereum Foundation, Solana, Base, Sui, Aptos, and Optimism. OKX expressed enthusiasm about collaborating with these influential teams, stating their alignment with a vision for an open agentic economy.
However, the introduction of the APP comes amidst heightened competition within the evolving space of agentic commerce. Competitor Coinbase has expanded its x402 protocol with the Agentic.market, allowing AI agents to locate and pay for services without the need for API keys. Coinbase’s product lead highlighted that their platform offers access to numerous services without requiring any API keys. In parallel, Visa has rolled out tools designed to support AI-driven card payments, while Stripe-backed infrastructure is launching frameworks for programmable machine-to-machine payments.
While the APP presents promising features, some key functionalities are still under development. Planned enhancements include an escrow system, which would ensure that funds are only disbursed upon fulfillment of delivery conditions, and a built-in dispute resolution mechanism, both of which are pivotal to the protocol’s comprehensive commerce approach.
The overall market for AI-driven payments remains in its early stages. Notably, daily transactions facilitated by Coinbase’s x402 have seen a drastic decline—from 731,000 in December 2025 to approximately 57,000 by March 2026, reflecting a staggering 92% drop. Further complicating the landscape, research firm Gartner has predicted that more than 40% of AI agent projects may be terminated by 2027, driven by escalating costs and ambiguous business value propositions.
The success of OKX’s Agent Payments Protocol will hinge on the extent of developer adoption and the volume of real-world transactions it can generate through its infrastructure, posing challenges that the company will need to navigate in the coming months.
