About

I built KeyCage at NEAR HACKATHON. My agent gets a function call key that can call only pay on my PolicyVault. The vault calls the allowed method on the receiver. A prompt injected agent was stopped on chain, and risky spends wait for my approval. Proof hashes are in the panel.

Media

From the builder’s post on X. Images and video are streamed from X’s servers, not copied.
