Open Source TypeScript Payment Gateways

Issues and code: https://github.com/OpenReceive/openreceive OpenReceive is free, open-source (MIT) checkout software that runs inside your own website or app. Customers pay with Bitcoin over Lightning, and the money goes straight into a wallet you control: there is no OpenReceive account, no API key, no processing fee, and OpenReceive never holds funds. It connects to your wallet with a receive-only Nostr Wallet Connect (NWC) code (Rizful, Alby Hub, Zeus, LNbits and others), which can create invoices but cannot spend. Unlike BTCPay Server, it needs no separate server or node: it runs in your app and keeps payment attempts in your existing database. Optionally, customers can pay with USDT, USDC, SOL or ETH through a swap provider you configure, and you still receive Bitcoin over Lightning.
