Money Dev Kit Overview Integrate Lightning payment workflows using Money Dev Kit. Use this skill when tasks involve setting up @moneydevkit/agent-wallet for autonomous agents, wiring @moneydevkit/nextjs or @moneydevkit/replit checkout flows, bootstrapping credentials via @moneydevkit/create , validating MDK environment variables, or applying hybrid architecture constraints (hosted API plus self-custodial node). Environment Requires bash , curl , and Node.js 20+. Requires internet access to npm and Money Dev Kit services. Use this skill for implementation tasks, not high-level Lightning theory. Workflow Choose the right integration path first: agent-wallet path for autonomous agents and CLI automation (no API account required). nextjs or replit checkout path for hosted checkout UI and product catalog workflows (requires credentials). Run preflight checks: scripts/check-mdk-prereqs.sh agent-wallet for wallet automation path. scripts/check-mdk-prereqs.sh checkout for API/checkout path. Execute the selected path: Agent wallet flow from agent-wallet-operations . Checkout flow from checkout-integration . Apply architecture and custody constraints: Use architecture-and-self-hosting before finalizing deployment. Explicitly handle mnemonic custody, API key handling, and self-hosted vs hosted service decisions. Verify outcome: For wallet path: can receive , send , and inspect payments with JSON responses. For checkout path: can create checkout, render hosted checkout page, expose /api/mdk , and verify paid status. Quick Commands

Agent wallet path (signet recommended for testing)

npx @moneydevkit/agent-wallet@latest init --network signet npx @moneydevkit/agent-wallet@latest status npx @moneydevkit/agent-wallet@latest balance

Checkout path credential bootstrap

npx @moneydevkit/create@latest
