OKX’s agent payments protocol opens blockchain commerce to AI agents

OKX has launched the agent payments protocol, an open system built to let AI agents handle commercial operations on blockchain networks.

What the protocol is designed to do

The launch, announced on Wednesday, expands payment handling for more complex deals between agents. Moreover, OKX said AI agents can create quotes, negotiate terms, hire professionals, set up escrow accounts, make lump-sum payments, and run pay-per-use billing systems.

The protocol is also built for autonomous payment systems and agent-to-agent communication across the full commerce lifecycle. That said, it supports structures such as upfront payments, top-ups, deductions, and different billing plans.

OKX ties the rollout to Onchain OS

OKX said it will work from the start with developer teams including the Ethereum Foundation, Uniswap, and Solana. The company said the goal is an open agentic economy tied to its broader Onchain OS initiative.

In this setup, the company is targeting onchain commerce, with protocols for interaction, negotiation, and transaction settlement carried out by AI agents over blockchain. However, OKX said the system is meant to close a practical gap between reasoning and real business execution.

AI systems can already make decisions, but they still struggle with real-world workflows, especially payments. For that reason, OKX framed the agent payments protocol as infrastructure for commerce that agents can run more independently.

$RLUSD also goes live on OKX

In parallel with the protocol launch, OKX said Ripple’s USD-pegged stablecoin, $RLUSD, will be traded on its platform. Starting Wednesday, the $RLUSD/$XRP pair and additional $RLUSD spot trading pairs became available.

Moreover, OKX said $RLUSD can also be used as collateral in perpetual futures. The company added that $RLUSD supports deposits and withdrawals in XRPL markets.

OKX is positioning both moves as part of a broader push into blockchain-based commerce and settlement. The rollout links AI agents, trading infrastructure, and payment tools in a single operational stack.
