OKX introduced a new framework designed to extend how artificial intelligence systems participate in economic activity, with a focus on completing entire business transactions rather than executing isolated payments.
The exchange announced the Agent Payments Protocol (APP) on April 29, positioning it as infrastructure for what it describes as an emerging “agent economy.” The system allows AI programs to manage processes such as quoting, negotiating, escrow, usage tracking, settlement, and dispute resolution within one structure, according to OKX’s official materials.
“In the past few months, AI agents moved from answering questions to running workflows, managing business processes, and acting autonomously on behalf of users,” OKX stated. The company added that “the bottleneck shifted from intelligence to commerce, not just paying, but the full cycle of doing business.”

For the first time, agents can quote, escrow, transact & resolve disputes autonomously.

Protocol aims to move beyond single-payment systems
OKX framed the release as a departure from existing machine-payment tools that focus on one-step transactions. The company cited systems such as x402, developed within the ecosystem of Coinbase, which enable AI programs to pay for services in small increments but do not cover broader commercial processes.
“Existing agentic payment solutions handle none of this,” OKX stated, referring to functions such as escrow and dispute handling.
APP introduces a structure where AI agents can negotiate terms, lock funds, verify task completion, and release payments automatically. Some features, including escrow and dispute resolution, remain under development, based on the company’s announcement.
The protocol operates as an open standard that can function across multiple blockchains, including Ethereum and Solana. OKX said developers can integrate payment functions through its software development kit, which supports one-time, batch, and usage-based transactions on its X Layer network.
Wallet and infrastructure support autonomous execution
A key component of the system involves a self-custodial wallet designed for AI agents. The wallet uses trusted execution environments to secure access and supports more than 20 blockchain networks, according to OKX.
The company said agents can communicate through standard internet protocols such as HTTP and messaging systems including Telegram and XMTP, which enables coordination between different AI programs without manual intervention.
In practical terms, the protocol allows scenarios where one AI agent requests data or services and completes payment instantly, or hires another agent for a task with funds held in escrow until delivery is verified. OKX described these processes as part of a continuous workflow that does not require logins, invoices, or manual approval.
Industry efforts highlight competition in AI payments
The launch takes place amid broader efforts to develop infrastructure for AI-led transactions. Coinbase has expanded its x402 ecosystem with a marketplace known as Agentic.market, where AI agents can locate and pay for services without API keys, according to statements from Coinbase product lead Nick Prince.
Prince described the platform as designed to “give humans and their agents access to thousands of services, with zero API keys required,” and called it “a storefront for discovering, comparing, and using x402 services.”
Other firms have also moved into the space. Stripe has worked on machine payment systems aimed at high-frequency transactions, while cloud providers such as Amazon Web Services and Alibaba Cloud have supported development of agent-based payment standards.
OKX said it collaborated with blockchain ecosystems including Base, the Ethereum Foundation, Sui, Aptos, and Optimism as part of the rollout.
Executive comments link release to broader strategy
OKX Global CEO Star Xu described the protocol as a step toward practical deployment of AI-driven commerce.
“Built on years of accumulation in on-chain infrastructure and AI, and co-created with a group of outstanding partners,” Xu said, adding that the protocol is “the key step that brings the Agent economy to real-world implementation.”
The company has also expanded its institutional infrastructure in parallel. OKX integrated off-exchange settlement technology from BitGo in the United States, which allows firms to trade assets while keeping custody with a third party.
According to OKX U.S. CEO Roshan Robert, the structure addresses institutional requirements for asset protection and capital efficiency.
“Institutional capital entering crypto requires capital to be protected and to be put to work,” Robert said.
BitGo noted in its IPO filing that such arrangements can introduce operational risks, including processing delays and reconciliation issues.
Rollout reflects early-stage market conditions
While APP introduces a broader framework for AI-driven transactions, parts of the system remain incomplete. Core payment functions are active, while escrow and dispute mechanisms are still in development.
The wider market for AI payments continues to evolve. Data referenced in earlier reporting shows transaction volumes in some existing systems have declined, which indicates uneven adoption. Separate projections from Gartner suggest a significant portion of AI agent projects could face cancellation due to cost pressures and unclear business value.
These conditions place APP within an early-stage sector where infrastructure development continues alongside uncertain demand. OKX’s release focuses on expanding technical capabilities, with the expectation that broader usage may follow.
