Algorand Foundation Releases AC2 Protocol for User Approval of AI Agent Actions

On August 25, the Algorand Foundation disclosed the Agentic Communication and Control Protocol (AC2), an open-source standard, aimed at enabling users to approve AI agent actions while preserving their private keys. This protocol tackles a growing governance issue as AI agents increasingly manage payments, software deployment, and API authorizations.
By requiring user approval for signing requests instead of transferring private keys to the agent, AC2 mitigates the risk of potential damage if an agent is compromised. The user reviews the details of the request and signs on a personal device, after which the authorization is returned to the agent, keeping the private key with the user.
Despite the increased security from separating agent capability from signing authority, AC2 does not eliminate the risk of malicious or incorrectly constructed transactions. It also introduces the possibility of approval fatigue if users are frequently prompted for approval. Interoperability is another challenge, as the protocol relies on established standards but requires consistent implementation across wallets, agent frameworks, and service providers to become an industry standard.
