AC2 Protocol: Giving AI Agents Cryptographic Proof of Intent

AC2 Protocol: The missing security layer for AI agents

The AC2 Protocol, an open-source project by the Algorand Foundation, adds a missing security layer for AI agents. It uses hardware-bound FIDO2 signatures to verify human intent before agents execute sensitive actions like payments or code deploys. Credentials stay on the user's device, and every approval is cryptographically signed for a defensible audit trail. AC2 integrates with agent frameworks like OpenClaw via a plugin and works without a blockchain or central relay.
