OKX launches the Agent Payments Protocol (APP), an open standard designed to enable full-cycle, AI-led transactions across multiple blockchains.

Interoperability efforts involve ecosystems such as Base, Ethereum Foundation, Solana, Sui, Aptos, and Optimism to ensure cross-chain compatibility.

OKX’s self-custodial Agentic Wallet supports trusted execution environments and can hold and transfer funds across more than 20 chains, enabling autonomous agents to manage funds securely.

Experts say such rails could promote microtransactions and programmable, conditional payments between software agents without human intervention.

OKX is moving from a trading venue toward an infrastructure provider, investing in autonomous agent infrastructure; a recent strategic investment from Intercontinental Exchange valued OKX at about $25 billion.

The initiative fits broader trends in agentic commerce, where AI agents autonomously run workflows and business processes.

The release is part of a wider industry push toward machine-driven payments, with parallel efforts from Coinbase (x402), Visa’s AI-driven payment tools for developers, and Stripe-backed Tempo/Machine Payments Protocol for high-volume programmable transactions.

Planned enhancements include escrow functionality and dispute resolution mechanisms, currently under development to ensure funds are released only upon delivery and to resolve disputes.

Early supporters include AWS, Alibaba Cloud, the Ethereum Foundation, Solana, Uniswap, Paxos, and MoonPay.

APP enables a single AI agent to manage end-to-end business relationships autonomously, reserving human input for exceptional cases and addressing gaps where current tools handle only single transactions.

Developers can use OKX’s tools on X Layer, with potential gas-free stablecoin transfers for certain actions.
