[Analyst Says AI Agents' Real Transaction Volume via x402 Protocol is Only $1.6 Million] On March 12, a16z partner Noah Levine stated that the x402 protocol built by Coinbase has been integrated by Stripe, Cloudflare, and Vercel, and Google has also incorporated it into its agent payment protocol. However, discrepancies exist in the on-chain payment data initiated by AI agents via the x402 protocol. Bloomberg reported a total payment volume of $24 million over the past 30 days, Allium Labs' on-chain data shows approximately $3 million, and Artemis Analytics analyst OnchainLu adjusted the figure to $1.6 million after filtering out wash trading.
