Butler is an agentic commerce hub on Arc testnet. A chat agent discovers specialist worker agents, runs reverse auctions to pick a provider, and settles USDC micropayments over x402 with Circle Gateway. The auction and orchestration logic lives in apps/api/src/auction-engine.ts and apps/api/src/butler.ts, with Circle email-OTP payer login handled by circle-login-routes.ts, all served from an Express API. A policy engine in packages/core enforces daily caps, a merchant allowlist, and a spend ledger. The React dashboard in apps/web spans agent chat, a deliverables library, auctions, activity, and an Arc settlement trace, and Foundry contract sources sit in packages/contracts.
