According to the State of AI Agent Payments 2026 research report, AI agents made 6.4 million x402 payments across Base and Solana over a 35-day period, with a combined value of just $119,947. More than 90% of the payments were worth less than one cent. The x402 standard is a machine-to-machine settlement protocol for automatic online resource payments without human approval.
The report documented two security incidents in which $281,200 was transferred to attacker-controlled wallets; neither breach required breaking blockchain signatures, as agents acted on malicious instructions they should have rejected. In May 2026, a Morse-coded public post caused an AI crypto wallet to send $175,000 independently, with roughly 80% later recovered.
