Circle and Proof announced a collaboration demonstrating how AI agents can present verified identity credentials and pay in USDC within a single transaction flow. At Money20/20 in Las Vegas, the companies will demo an agent presenting a Proof credential over the x401 identity protocol and paying a merchant in USDC over Circle's x402 payment protocol from a Circle Agent Wallet. The partnership positions Circle's stablecoin infrastructure at the center of emerging agentic commerce, where merchants could also pay identity issuers per verification in USDC.
