Circle and Proof will demonstrate at Money20/20 how AI agents present verified identity credentials through Proof’s x401 protocol and pay merchants in USDC through x402 from Circle Agent Wallet. Once merchants verify the credential signature, the transaction can be completed; the two companies said that combining identity and payment protocols can help businesses build trust in agent transactions.
