FAQ

What is a "noffer"?

A noffer is a CLINK Offer string (noffer1...) that advertises your Lightning node's ability to receive payments. Generate one from ShockWallet, Lightning.Pub, or any CLINK-compatible wallet. See Generating a noffer.

Which wallets can customers use?

Any CLINK-compatible Lightning wallet: ShockWallet, ZEUS, BXRD.app, Amethyst, and others.

Does this need a Lightning node on my server?

No. All communication flows over Nostr relays. Your Lightning node only needs a Nostr connection — no open ports, no web server required.

Are subscriptions supported?

Yes. Subscriptions work with WooCommerce Subscriptions, Subscriptions for WooCommerce, YITH WooCommerce Subscription, Flexible Subscriptions, and others. After the first payment, customers can authorize auto-renewal via a CLINK ndebit string — future payments are then processed automatically without scanning QR codes. See Auto-Renewal.

How is the BTC price determined?

The plugin fetches the live BTC price from CoinGecko with a 5-minute cache. You can optionally set a fixed rate in the settings, which bypasses CoinGecko entirely.

Does this plugin work with Custom Price for WooCommerce Pro?

Yes. The plugin uses PHP_INT_MAX priority for all price filters and includes a client-side JavaScript fallback that converts prices in the browser, ensuring compatibility with Custom Price for WooCommerce Pro and similar price-display plugins.

Why is my store's price displayed in sats?

The Display Amount As setting is set to Satoshis by default. Change it to BTC or ₿ (bip-0177) in Configuration, or use the Fixed BTC Rate to keep prices in fiat.

The customer paid but the page didn't move / showed a new QR code?

This was a known bug fixed in v1.1.0. After the payment receipt arrives, the page now immediately shows a "Payment confirmed" screen and redirects to the order summary. Update to the latest version.

Is the customer's data private?

No personal customer data (name, email, address) is transmitted to Nostr relays. Only the payment amount and a short order description are shared. See Third-Party Services for details.
