AC2 Protocol Adds Cryptographic Sovereignty to AI Agent Workflows
August 27, 2026
AC2 implements a communication and control protocol using self-custodial signatures and FIDO2 hardware-bound approvals for AI agents. It enables verifiable intent and credential isolation, ensuring private keys remain on-device during sensitive agentic operations like payments or code signing.
