OKX has launched its Agent Payments Protocol (APP), setting the stage for a significant shift in how AI systems conduct transactions across various business activities. The newly introduced open standard aims to go beyond mere financial transfers, empowering AI agents to oversee complete commercial processes, which include pricing, negotiation, escrow, settlement, and handling disputes.
The exchange emphasized that advancements in AI have transitioned agents from simplistic tasks to executing complex workflows and managing operational activities. As a result, the challenge has evolved from merely enhancing intelligence to streamlining commerce—a shift that existing transaction systems haven’t effectively addressed.
Designed as an open standard, the APP will operate across multiple blockchains, with initial implementations focusing on well-known networks such as Solana and Ethereum. A Payment Software Development Kit (SDK) accompanies the protocol, enabling developers to facilitate one-time, batch, and usage-based payments through the X Layer infrastructure, which promises low or even no gas fees for transactions.
OKX has seamlessly integrated its self-custodial Agentic Wallet into the system. This wallet, which employs trusted execution environments, supports operations across more than 20 chains, allowing AI agents to independently hold and transfer funds while ensuring security. The APP also features communication capabilities, enabling agents to connect using standard internet protocols like HTTP and XMTP, along with messaging applications such as Telegram. This setup facilitates seamless interactions between autonomous systems during transactions.
Future enhancements to the protocol are in the pipeline, notably the introduction of escrow features that will ensure funds are released only once specified delivery conditions are met. Additionally, built-in dispute resolution mechanisms are also under development.
This launch aligns with a broader industry trend where various firms are striving to establish standards for AI-driven transactions. For instance, Coinbase has unveiled its x402 protocol to facilitate stablecoin payments among agents, along with an accompanying marketplace that allows AI systems to autonomously discover and procure services without requiring API keys. Coinbase’s product lead highlighted the platform’s capability of providing access to numerous services without the need for human intervention.
Visa has also made strides in this area with the introduction of a command-line tool that enables AI systems to conduct card payments during developmental workflows, thereby eliminating reliance on sensitive API credentials. Moreover, infrastructure supported by Stripe has progressed with the launch of the Tempo blockchain and a Machine Payments Protocol, geared towards high-volume, programmable transactions across various payment channels.
OKX’s APP builds on these initiatives by focusing on complete transaction execution rather than just isolated payment tasks. The protocol has garnered support from notable cloud and technology providers such as AWS and Alibaba Cloud, as well as numerous crypto firms including Nansen, Uniswap, Paxos, and QuickNode. At the blockchain level, OKX has collaborated with ecosystems including Base, the Ethereum Foundation, Solana, Sui, Aptos, and Optimism to enhance interoperability.
OKX CEO Star Xu heralded the release as a pivotal step toward realizing the potential of the Agent economy in real-world applications. He noted in a recent post on X that the protocol has been co-developed in conjunction with partners across various sectors, including cloud infrastructure, public chains, decentralized finance, and artificial intelligence.
