OKX, a prominent cryptocurrency exchange, has unveiled an innovative open protocol aimed at enabling artificial intelligence agents to independently execute complete business transactions. This development marks a significant leap from simple machine payments to comprehensive commercial activities, covering everything from initial negotiation to final settlement.
The newly launched Agent Payments Protocol empowers AI systems to handle not only payments but also quoting, negotiation, escrow, usage tracking, settlement, and dispute resolution within a unified framework. According to OKX, recent advancements have seen AI agents evolve from answering queries to managing workflows and autonomously representing users in business processes. The company identifies the primary challenge as shifting from intelligence to commerce, specifically addressing the full business cycle rather than just payment execution.
Existing solutions like x402 primarily facilitate machine-to-machine transactions, but OKX argues they fail to support the entire commercial lifecycle. The Agent Payments Protocol fills this gap by incorporating features such as escrow and dispute resolution, which are slated for future updates. Built as an open standard, the protocol is compatible with multiple blockchains, including Ethereum and Solana. Developers can integrate one-time, batch, or pay-as-you-go transactions using the Payment SDK and OKX’s X Layer blockchain, with minimal or zero gas fees.
A self-custodial Agentic Wallet, secured by trusted execution environments, supports over 20 chains. The protocol also enables agent communication via HTTP and XMTP, along with integration with messaging platforms like Telegram. Escrow functionality ensures funds are released only upon service delivery, and built-in dispute resolution tools are currently under development.
The launch aligns with broader industry efforts to build infrastructure for AI-led transactions. Coinbase has expanded its x402 ecosystem with Agentic.market, where AI agents can discover and pay for services without API keys. Infrastructure from Stripe is also focusing on high-volume machine transactions, while Amazon Web Services and Alibaba Cloud support agentic payment standards. OKX collaborated with ecosystems such as Base, Ethereum Foundation, Sui, Aptos, and Optimism at the blockchain level.
OKX Global CEO Star Xu emphasized that the protocol is built on years of on-chain infrastructure and AI development, created with outstanding partners, and represents a key step toward implementing the agent economy in real-world scenarios. The release follows OKX’s recent expansion in institutional services, including integration with BitGo’s off-exchange settlement system in the U.S., which allows firms to trade while keeping assets under third-party custody, thereby improving capital efficiency.
