Proof and Circle Internet Group (NYSE: CRCL) announced a collaboration showing how verified identity and machine-native payments can work together in AI agent transactions. They will demonstrate it at Money20/20 in Las Vegas, October 19–21. In the demo, an AI agent presents a verified Proof credential over x401, Proof's open identity protocol. It then pays the merchant in USDC over x402 from a Circle Agent Wallet. Businesses can currently see that an agent pays, but not who sent it or whether that person approved the purchase. The merchant checks the credential's signature without calling Proof, and keeps signed evidence of approval. Proof says the protocols could also let merchants pay identity issuers for each check. Proof published x401 in June.
Proof has launched x401, an open protocol that lets websites ask an AI agent to prove who it acts for and what that person approved. The Boston company says it is the first to put verified legal identity and transaction authorisation for AI agents into production. A person approves each action on their own device through Proof's agent identity wallet, which signs the request. If an agent alters the amount, recipient or other signed terms, the signature fails. The protocol works with assistants that support the Model Context Protocol, including Meta's Muse, ChatGPT dots, Grok and Claude. Websites can request identity claims without a sales process, and can pay per claim over x402. The launch follows Amazon's September 21 block of Muse, which it said did not identify itself. Superfluid is among the first to run x401 in production.
Proof and Enigma have partnered to launch Business Certificates, a verified credential system addressing business identity fraud and securing agentic commerce. The solution combines Enigma's business identity data with Proof's authorisation infrastructure to bind current business identities to authorised individuals and systems. According to FinCEN analysis of Bank Secrecy Act filings, false records represented part of $212 billion in suspicious activity. Traditional KYB verification provides only a timestamp, creating gaps exploited by fraudsters impersonating businesses through spoofed domains and fabricated executives. Business Certificates use continuously updated data covering over 100 million US legal entities, reflecting real-time changes in ownership, licensing, or sanctions status. The system integrates with Proof's x401 protocol for AI agent verification. Proof has secured over $640 billion in transactions for 10,000 organisations, including 16 Fortune 100 companies. Business Certificates are now available.
Proof, an identity authorisation network that has secured over $640 billion in transactions for more than 9,000 organisations, has joined the FIDO Alliance as a Sponsor member. The move comes as FIDO expands its authentication standards to support AI agents acting on behalf of users. Proof has developed a Know Your Agent capability that verifies a person's identity to NIST IAL2 standard and cryptographically binds that verified identity to every action an AI agent takes on their behalf. The company operates as a Certificate Authority, creating an unbroken chain of trust from enrollment to transaction execution. The announcement follows OpenAI's decision to join FIDO's Board of Directors and contributions from Google and Mastercard. FIDO has made agent-based interactions a central priority for 2026.
IDEMIA Public Security and Proof have announced a strategic partnership to deliver privacy-preserving digital identity solutions using verifiable digital credentials (VDCs) that work across physical and digital ecosystems. The collaboration combines IDEMIA's identity verification and biometric technologies with Proof's PKI-based digital signature network. The partnership aims to create an interoperable identity framework enabling financial institutions and enterprises to verify reusable digital credentials that are user-controlled and privacy-preserving. The system uses cryptographic certificates, selective disclosure and zero-knowledge proofs to minimise data sharing whilst addressing payments fraud and KYC requirements. Users will maintain full control over their credentials, with the ability to revoke access at any time. The framework allows individuals to verify their identity with a single portable credential wherever verification is required.
