OKX launches Agent Payments Protocol for AI payments

OKX announced on April 29, 2026 the Agent Payments Protocol, a system designed to let autonomous AI programs execute full commercial transactions without human intervention. The company says the protocol covers quoting, negotiating terms, locking funds in escrow, verifying completion and releasing payments, with an agentic dispute process for resolving problems.

The exchange described the protocol as completing the full business cycle for AI-managed transactions. CEO Star Xu described the launch as “the key step that brings the Agent economy to real-world implementation.” OKX wrote that the system lets an AI create a quote, agree terms, hold funds, check that contracted work is finished and settle the final payment.

OKX has built supporting infrastructure, including the Agentic Wallet released March 18, 2026. The wallet stores a secret unlock code inside a protected chip using a Trusted Execution Environment that the company says cannot be read by anyone, including OKX. The Agentic Wallet supports more than 20 blockchains, including Ethereum and Solana, and the OKX X Layer network, which the company says does not charge gas fees. The wallet can host as many as 50 sub-wallets so a single AI program can manage multiple accounts concurrently.

Technology partners include Amazon Web Services, Alibaba Cloud, Sahara AI and QuickNode. Blockchain and analytics partners listed by OKX include Nansen, Uniswap, Paxos and several layer-1 projects: the Ethereum Foundation, Solana, Base, Sui, Aptos and Optimism. OKX says those integrations will let developers on the partner platforms connect agent payment functions to existing services.

Other firms have released related products. Coinbase reports its x402 protocol has processed over 100 million transactions with an annualized volume near $600 million and offers a marketplace where agents can buy services such as cloud compute. Stripe released a Machine Payments Protocol aimed at machine-to-machine transactions. OKX wrote that existing agentic payment solutions were designed for single payments on single requests and do not manage ongoing relationships between agents and providers.

Not all components of the Agent Payments Protocol are live. OKX reports that one-time and batch payments and agent-to-agent messaging via platforms like Telegram are functional. Escrow payments and the dispute-resolution layer remain under development. The company says those elements are necessary for managing commercial risk in business deals.

Market activity for AI-driven payments is limited. Daily transactions on Coinbase’s x402 dropped from roughly 731,000 in December 2025 to about 57,000 in March 2026, a decline of about 92 percent. Analyst firm Gartner projects more than 40 percent of AI agent projects could be canceled by 2027 because of rising costs and unclear business value.

OKX and its partners have released the protocol and supporting tools while several technical and market challenges, including escrow handling, reliable dispute resolution and business adoption, remain to be completed for wider commercial use.
