How it works

Type amount.
Scan or Tap.

The RIC is an always-on terminal that makes accepting bitcoin feel like any other payment: the same three moves, every time, no hesitation. Run as many RICs as you have counters, all on the same account.

It works both ways. Buy and sell bitcoin for cash, in person, with no extra setup.

  1. 01

    Staff type the amount.

    Keypad and screen always ready. Same as any card terminal.

  2. 02

    Customer taps a card or scans.

    An openLN card, any Bolt Card, or any Lightning wallet by QR.

  3. 03

    Sats land in the merchant's wallet.

    Their wallet, their keys. The same terminal also writes and wipes Bolt payment cards at the counter.

Tap-to-pay cards

A card that pays
from your wallet.

Link an NTAG424 DNA card to your openLN account. Tap it at a RIC or any terminal that takes Bolt Cards. The payment comes from the wallet you control. Freeze or wipe it from the app.

Cashflow

A route,
not a vault.

openLN routes the payment and takes a routing fee, nothing more. The customer's sats lock to a hold invoice and land in the merchant's own wallet, settled in one motion.

Your wallet connects over Nostr Wallet Connect (NIP-47). openLN never holds your keys, and there is no openLN balance to withdraw. Payments pass through, only the routing fee is left behind.

Compatibility

Your wallet is
already supported.

openLN connects to the Lightning wallet you already run: send and receive over Nostr Wallet Connect, connect Blink with an API key, point a Lightning Address at your account for receive-only, or connect CLINK codes from Lightning.Pub or ShockWallet, one for receive and one for send. Your keys, your sats, nothing to migrate.

Compatibility is by standard, not by brand: any NIP-47 wallet connects over Nostr Wallet Connect (send + receive), any Lightning Address connects receive-only with sales confirmed by openLN's wrapped settlement, any node backs an account through a Hub or bridge, Blink accounts connect with an API key, and CLINK codes from Lightning.Pub or ShockWallet cover receive and send. This wall lists only what connects today.

Partners

Built Locally.

FAQ

Straight
answers.

What do I need to start?

A Lightning wallet and a phone. Create an openLN account, connect your wallet, and open the point of sale in your browser. Add a RIC when you want a dedicated terminal at the counter.

Who holds the money?

You do. Each payment goes straight to your own wallet. openLN never holds keys or balances and keeps only its 2% routing fee.

What does it cost?

The RIC terminal is $49, with three tap cards in the box. Each payment carries a 2% routing fee.

How do customers pay?

They tap an openLN card or any Bolt Card on the RIC, or scan the QR code with any Lightning wallet.

Which wallets can I connect?

Any wallet that supports Nostr Wallet Connect, a Blink account, or a Lightning Address for receive-only payments. When your wallet provider cannot verify a payment itself, openLN confirms the sale for you. The full list is under Wallets.

Do my staff need to understand bitcoin?

No. They type the amount, like on any card terminal. The customer does the rest.

Is it open source?

Yes. The platform is AGPL-3.0 and the firmware is MIT. Read it, build it, run your own.
