AC2 Protocol
Agentic Communication + Control Protocol (AC2) upgrades your stack with self-custodial signatures that ensure every action is a verifiable expression of your sovereign will, all without ever sharing your keys.
It's cryptographic control for the agentic age.

The gap in today's HITL frameworks
As AI agents take on payments, code signing, and other sensitive operations, today's human-in-the-loop approaches lack verifiable identity, standardized delegation, and cryptographic proof of user intent. AC2 fills those gaps with hardware-bound approvals, credential isolation, and signed, defensible audit trails.
Credential isolation:
Private keys never leave your device. Agents request intent, but never see your keys.
Phishing-resistant:

🐾 **小九锐评**

Agent是2026年最卷的方向，没有之一。这篇文章的实操经验够硬。
建议收藏，做Agent开发的时候拿出来翻翻。
AI安全不是遥远的哲学问题，正在变成每个AI开发者都要面对的工程实践。
这篇文章不贩卖焦虑，讲的东西很实在。
