insert coin here.

A machine left out in the open. It asks for nothing — it just stands there, patient and glinting, a sail rigged for whatever the wind brings. If a gust moves you, drop a few sats (tiny fractions of Bitcoin) over Lightning. One coin is enough to fill it.

It is not a cup held out. It's a sail, rigged and waiting.

Most asks for money lean in close — they tug your sleeve, they follow you down the page. This one doesn't. It's a piece of canvas hung in the open air, doing the one thing canvas does: catching whatever the wind decides to give.

Most days it just stands there, polished and unbothered. Then a stranger passes with the wind at their back, the sail snaps taut — and that one gust is the whole point. The machine keeps its dignity either way, but it was built for the moment a coin it never demanded comes through.

How the coin actually falls.

Behind the gold coin slot there's no jar. Each coin you drop generates a fresh, single-use payment QR code — a new one every single time — so nothing is reused and no fixed address or payment link is ever left standing in the open for anyone to watch.

The money goes straight from your hand to the owner's Lightning Node. No middleman stands between, almost no fee is shaved off the top, and the owner's funds are never in anyone else's hands.
