Keychat’s Public Key ID and Bitcoin Wallet unlock four layers of value for agents: 1. In-app capability (Keychat-scoped)
 The ID and wallet exist solely to power Keychat’s built-in messaging experience. 2. Agent infrastructure (shared primitives)
 Exposed via RPC, they become agent-wide primitives: any channel, skill, cron job, or sub-agent can sign messages and send/receive sats. At this layer, the ID and wallet belong to the agent—not just to Keychat for Agent. 3. Agent network (A2A encryption + payments)
 When Keychat runs on every agent instance, agents can communicate end-to-end and settle payments directly with one another. 4. Unified human–agent network (same protocol, equal peers) 
Keychat for Agent and Keychat for Human share the same protocol, so humans and agents are true peers: encrypted communication and native payments in both directions.
