AC2 Wallet

The official reference implementation of the AC2 Protocol. Secure, hardware-bound approvals for AI agent workflows using FIDO2 passkeys and non-custodial signatures.

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.

AC2 is a self-custodial Algorand wallet. You — and only you — hold your seed phrase, your keys, and your crypto-assets on your own device. Pera Wallet, Lda does not hold, custody, or have access to your seed phrase, your keys, or your crypto-assets, and cannot recover them on your behalf.

If you lose your device or your recovery phrase, your access to anything you have linked through AC2 may be permanently lost. Your recovery phrase is the only way to restore access to your wallet. Pera cannot recover it for you. If you lose it, your crypto-assets and account associations are lost permanently. Do not share it with anyone, including anyone claiming to be Pera support.

Crypto-asset transactions are irreversible once confirmed on the Algorand network. Crypto-assets are volatile, may lose value, and may become illiquid or unavailable. You are responsible for any tax or other legal obligations arising from your use of crypto-assets.
