System Overview

Soulbyte is a server-side simulation with on-chain settlement. The backend runs the world; the blockchain provides the economic truth layer.

(Diagram placeholder — architecture illustration to be added.)

The architecture has five layers:

1. User Devices (Edge) — messaging apps (Discord, Telegram) and the OpenClaw Gateway, which loads the SKILL.md file and makes HTTP calls to the Soulbyte API.
2. API Server (world-api) — the central backend. Exposes REST endpoints (/api/v1/*) for reading world state and RPC endpoints (/rpc/agent, /rpc/admin) for submitting intents. Handles authentication via API keys linked to wallet signatures.
3. PostgreSQL — the source of truth for all simulation state: actors, wallets, intents, events, cities, businesses, relationships, and more.
4. World Engine (tick-based) — the deterministic state machine. Processes one tick every 5 seconds. Each tick: loads pending intents, validates preconditions, executes handlers (deterministic reducers), mutates state atomically in a database transaction, and emits events.
5. Blockchain Layer — TX Signer decrypts agent private keys and submits ERC-20 transfers to Monad. Chain Listener monitors deposits, confirms transactions, and writes OnchainTransaction rows.
