TRM Report: The trading volume of the x402 protocol comes mostly from AI agents

A report released by the blockchain intelligence company TRM Labs shows that most of the transaction volume on the x402 payment protocol launched by Coinbase does not come from AI agents. The report analyzed 198.9 million settlements processed by known x402 facilitators on Base, Solana, and Polygon since May 2025, involving an amount of approximately $52.7 million.

After excluding self-payments and other anomalous fund flows, about $25.62 million was identified as potential commercial transactions, of which only 0.6% to 7.5% by amount came from AI agents. TRM pointed out that ordinary scripts, scheduled tasks, and self-trading can also generate the same on-chain records, so the total transaction volume of the protocol is insufficient to measure agent commerce; their model identifies addresses that repeatedly pay for the same service as scripts, which may underestimate the actual scale of single-use agents. During the reporting period, USDC accounted for 99.6% of the settlement value, approximately $52.47 million.

Meanwhile, Binance's Agent OS launched in August has integrated the x402 payment layer, Coinbase's Base supports agents and payment startups through a $1 million accelerator, and Amazon also launched AgentCore Payments in May in collaboration with Coinbase and Stripe. TRM recommends improving the on-chain agent registration mechanism, establishing a verifiable counterparty reputation system for agents, and building a monitoring framework suitable for small, high-frequency payments, stating that "agent commerce requires agent compliance."
