Built for the agentic age, AC2 helps developers, enterprises, and security-conscious users establish cryptographic control over AI-assisted actions. AC2 Wallet is the reference implementation for the AC2 Protocol, enabling secure, hardware-bound approvals for AI agent workflows. Using FIDO2 passkeys and non-custodial cryptographic signatures, AC2 Wallet allows you to authorize actions without exposing your private keys. Every approval generates cryptographically verifiable proof of intent, creating an auditable record of who approved what and when. With AC2, you can: - Prove that a human reviewed and approved code changes for an agent to merge - Prove that a human reviewed and approved communications for an agent to send, like client emails or social media posts - Validate agents to make direct x402 payments, without exposing your private wallet or account information - Enable agents to log in to platforms and continue workflows using a signed authorization from the user, so the underlying credentials stay on the user's device.
