Tkeeper

About

Tkeeper implements a "cryptographic identity" model for AI agents, pairing a private key with a manifest that defines exactly which actions it may sign; an agent must request a signature for a specific action and receives it only after policy checks pass. It uses threshold cryptography to split key control across multiple nodes so no single compromised node can steal the key or alter policies, with pluggable modules for agentic payments (Google AP2, Mastercard Verifiable Intent) and crypto wallet actions.
