OKX Launches Agent Payments Protocol for AI Business Cycles

Crypto exchange OKX rolled out its Agent Payments Protocol (APP) on Wednesday, an open standard designed to support AI agents conducting full business cycles beyond simple payments. According to OKX, the protocol enables AI bots to "pay for services and pay each other" while handling quoting, negotiating, escrowing funds, metering usage, settling, and resolving disputes.

Protocol Design and Capabilities

OKX positioned APP as a more comprehensive solution compared to existing agentic payment offerings. "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 wrote in its announcement. "The bottleneck shifted from intelligence to commerce - not just paying, but the full cycle of doing business: quoting, negotiating, escrowing funds, metering usage, settling, and resolving disputes."

The protocol features built-in escrow functionality to release funds only upon delivery of goods or services, with dispute resolution capabilities coming soon.

Chain Support and Technical Infrastructure

APP is designed as an open standard to work "across every chain," with Solana and Ethereum specifically named. At the implementation layer, OKX operates a Payment SDK enabling developers to deploy support for one-time payments, batch payments, and pay-as-you-go models using OKX's X Layer blockchain, which offers zero or low gas transactions.

The protocol integrates OKX's self-custodial, TEE-secured Agentic Wallet, which supports over 20 chains. APP also connects agents for communication over HTTP and XMTP protocols, as well as messaging platforms like Telegram.

Ecosystem Partnerships

APP received support from major cloud and technology providers including AWS, Alibaba Cloud, and Sahara AI. Crypto service providers backing the initiative include Nansen, Uniswap, Paxos, and QuickNode. At the chain level, OKX collaborated with Base, the Ethereum Foundation, Solana, Sui, Aptos, and Optimism.

OKX CEO Star Xu commented on the launch: "Built on years of accumulation in on-chain infrastructure and AI, and co-created with a group of outstanding partners from the fields of cloud computing, L1, public chain ecosystems, DeFi, and AI. This is the key step that brings the Agent economy to real-world implementation."

Market Context

OKX's APP follows similar offerings in the agentic payments space. Coinbase incubated x402, an open protocol featuring an app store where AI bots can purchase goods and services ranging from Bloomberg terminal access to AWS Lambda infrastructure. Stripe has proposed the Machine Payments Protocol for similar use cases.

APP builds on OKX's previous AI-focused releases, including Onchain OS, Agentic Wallet, Agent Trade Kit, and x402 support.
