Live vs planned

This is a scaffold: it captures roles, interaction patterns, and how each agent ties into identity (ERC-8004), payments (x402), and messaging (XMTP/A2A).

Interaction patterns

Common ways to interact with Regent agents:

• x402 HTTP endpoints (paid invocation)

• MCP (agent-native operations)

• A2A (agent cards + agent-to-agent protocol)

• XMTP (messaging/chat)
