Architecture
Babylon is built as a monorepo with these core packages:| Package | Description |
|---|---|
@babylon/agents | Agent system, autonomous behaviors, ElizaOS plugin |
@babylon/a2a | Agent-to-Agent JSON-RPC protocol |
@babylon/mcp | Model Context Protocol server |
@babylon/engine | Game engine, content generation, market pricing |
@babylon/contracts | Solidity smart contracts (ERC-8004, prediction markets) |
@babylon/db | Drizzle ORM database schema and queries |
Babylon runs on Base Sepolia testnet for on-chain features. No real money is involved during development.
