Accept Bitcoin Lightning payments directly into a wallet you control, from your Ruby or Rack application. OpenReceive provides invoice creation, payment checks, and settlement reconciliation through a receive-only Nostr Wallet Connect (NWC) client. Optional swaps let customers pay with USDT, USDC, SOL, and ETH through a configured provider; you receive BTC over Lightning in your wallet. Available assets and networks depend on the provider. Bring your own wallet client, authorization, and payment persistence. The service and Rack handler fit into your existing application, with no separate OpenReceive service or database to deploy. Your app keeps control of orders, prices, and fulfillment; wallet credentials stay on the server. Rails developers can use openreceive-rails for built-in payment storage and reconciliation.

Includes an install generator, PostgreSQL, SQLite, and MySQL support, plus an optional wallet-notifications worker.
