Understand the control plane before adding agents, tools, or financial actions.

Request topology
client -> api-bff -> agent-runtime                   |-> tool-gateway -> connectors                   |-> sandbox-runner -> E2B                   |-> onchain-engine -> signer boundary# workers -> durable jobs and reconciliation
API BFF
Authenticates B2C and B2B callers and owns the client contract.
Agent runtime
Runs the manager, specialists, sessions, guardrails, and tracing.
Tool gateway
Mediates MCP and connector calls without exposing provider tokens.
Sandbox runner
Executes bounded code and publishes scanned artifacts.
On-chain engine
Simulates typed intents, enforces policy, and isolates signing.
Workers
Runs restartable monitors, cleanup, retries, and receipt reconciliation.
