Welcome to the opencart-clink wiki

CLINK is a Bitcoin Lightning payment gateway for OpenCart 4. It implements the CLINK protocol (Common Lightning Interface for Nostr Keys) — payments are requested and delivered over a Nostr relay using signed, NIP-44-encrypted events. No payment processor, no API keys, no accounts.

Highlights

• One-time payments via CLINK Offers (noffer1... pointer)
• Recurring subscriptions via nDebit (ndebit1... pointer)
• QR-code checkout — scan with ShockWallet, ZEUS, Amethyst, or any CLINK-compatible wallet
• Fiat → sats conversion (CoinGecko live rates with cache, or fixed rate)
• OC4-native installer package — upload clink.ocmod.zip in Extensions → Installer

Pages

• Installation — requirements and both install paths (marketplace installer / manual copy)
• Configuration — every setting explained, getting your noffer1... pointer
• Architecture — the CLINK payment flow, protocol details, file structure, database tables
• Troubleshooting — stuck-spinner fixes, amount-mismatch causes, layout gotchas

Quick start

1. Generate a noffer1... pointer in your CLINK wallet
2. Install the extension (Extensions → Installer → upload clink.ocmod.zip)
3. Extensions → Extensions → Payments → install CLINK Payment
4. Configure your noffer, pubkey, and relay, then enable the method
