OpenReceive for SvelteKit
Accept Bitcoin & Stablecoin Payments With SvelteKit
OpenReceive has no SvelteKit package, and needs none. One +server.ts route hands each request to OpenReceive's web-standard handler, the Svelte checkout component draws the page, and the payment attempts live in your Postgres database.
Recipe
Why OpenReceive
- No OpenReceive account. There is no sign-up, no API key and no dashboard. Install the package, add a receive-only wallet code, and your server issues invoices itself.
- Open source, inside your server. MIT-licensed routes mount in the app you already run. OpenReceive never sees an order, a price or a customer, and never holds funds.
- Receive-only wallet permissions. The one credential is a receive-only NWC code. It can create invoices and read their status. It cannot spend, so a compromised server cannot drain the wallet.
- Stablecoins, optional. Connect a swap provider and customers can pay in USDT, USDC, ETH or SOL. Every payment still settles to your wallet in Bitcoin.

The live demo needs JavaScript: open the OpenReceive home page.
Set up
Requires Node ≥ 22, SvelteKit with @sveltejs/adapter-node.
1. Get a receive-only NWC code — get one here. It can issue invoices and watch for payment, and it can never spend from your wallet.
2. Get an LSC code for swaps (optional) — from a swap provider, only if customers should be able to pay in USDT, USDC, ETH or SOL.
3. Set the environment variables — NWC_URI (required) and
LSC_URI_PRIMARY / LSC_URI_BACKUP (optional) in the environment of
your SvelteKit server process; see
Environment variables.
4. Install
npm install @openreceive/http @openreceive/svelte pg5. Follow the recipe — Add the payment route and the checkout page. The recipe has the code, the database tables and the settings.
How it runs
- Tested on
- Node, checked with SvelteKit 3.0, adapter-node 6 and OpenReceive 0.4.25
- Databases
- PostgreSQL
- Secrets
- NWC_URI, and LSC_URI_PRIMARY for swaps, in the server's environment or .env file, never in browser code
- Refunds
- Refund a settled Lightning payment from your own wallet: the wallet code is receive-only. A swap deposit that never converted goes back to the payer through the checkout's refund form.
- Mobile apps
- No app SDK. A mobile app opens your checkout page in a browser tab, which the app stores allow for physical goods and real-world services; digital goods need a link-out program.
Practical questions
- Which currencies can customers pay with?
- Bitcoin over Lightning, always. With a swap provider configured, also USDT on Tron, Solana or Ethereum, USDC on Solana or Ethereum, ETH and SOL, each converted into the same Lightning payment. Automated swaps guide
- Where does the Bitcoin go?
- Into the wallet behind your NWC code. OpenReceive never holds funds: the invoice is minted in your wallet and the sats land there. Your server confirms settlement and runs your onPaid hook once per order. Payment storage guide
- What wallet do I need?
- Any wallet that issues receive-only NWC (Nostr Wallet Connect) codes, hosted or self-run. The code must be able to create invoices and read their status, and must not be able to spend. Get a receive-only NWC code
- What does it cost?
- OpenReceive is open source and free. Fees charged by your wallet provider, by a swap provider or by Lightning routing belong to those services and are outside OpenReceive's scope.
- What do I need to deploy?
- Node 22 or later with @sveltejs/adapter-node, a Postgres database, NWC_URI in the server environment, and OpenReceive's two payment tables. SvelteKit recipe
