Zero Trust AI.
Open Source Forever.
AI should answer to you, not to a platform. We build the protocol, the canvas, and the registry that give you cryptographic control over every agent interaction.
AI should answer to you, not to a platform. We build the protocol, the canvas, and the registry that give you cryptographic control over every agent interaction.
A zero-trust agent negotiation protocol. Mandate-based delegation, ephemeral session DIDs, selective disclosure, co-signed receipts. No new crypto, no token economy, no central registry.
Read the spec → Desktop AppOne canvas, many agents, your rules. Specialized agents work together on your tasks — each seeing only what it needs. Preview plans before execution, verify results after.
Try Papillon → Agent RegistryBuild an agent, publish it to the network. A self-hostable federated registry — sign a capability ad, push it to a node, and any PAP canvas can find you. No app store, no gatekeeper.
