Lightning
Lightning is Bitcoin's fast layer. Payments take seconds and cost almost nothing.
Satoshi
A satoshi, or sat, is the smallest unit of bitcoin. 100,000,000 sats make 1 BTC. Everything here is priced in sats.
Invoice
An invoice is a payment request with a fixed amount and a short deadline. We show it as a QR code and as text you can copy. If it expires, nothing is charged.
How to pay
- 1. Install a Lightning wallet funded with sats.
- 2. Scan the QR code or paste the invoice.
- 3. Confirm. The ranking updates on its own.
