⚡️ Open payment engine for stablecoins

Build, test and deploy stablecoin payments right from your laptop. Simulate invoices, subscriptions, or pay-per-API calls — then deploy anywhere in one click. Your cashflow earns yield by default. Open-source, portable, and built on modern standards (x402-ready).

MoneyMQ in action: 101 Series

💡 Key Features

🛠️ Integrated Local Environment

Spin up your entire payment stack locally — product catalog, billing rules and test accounts — without touching external APIs. Simulate checkouts, test 402-gated endpoints, and preview your logic in a real sandbox before deployment. MoneyMQ runs offline, integrates seamlessly with your existing tools, and treats billing as declarative YAML code — ensuring your production setup is reproducible and predictable.

🌎 The Easiest Way to Build with x402

MoneyMQ comes with native support for x402 payment flows. It automatically provisions a local sandbox with all required components — letting you test, iterate, and deploy x402 integrations in minutes.

🧠 MCP Embedded and Agent-Ready

With an embedded MCP runtime, MoneyMQ connects your agent directly to your payment stack and codebase. This enables autonomous agents to design, test, and optimize payment strategies — using real context from your codebase and environment.

💰 Embedded Yield (Coming soon)

Your balances don’t just sit — they earn. Idle stablecoin liquidity is automatically routed to yield strategies, so your cashflow grows by default.
