Pay by link

A pay link moves one note to a key you generate, and puts that key in the fragment of a URL, the part after the #. Browsers do not send the fragment to servers, so the secret stays with whoever holds the link.

Claiming

Open the link, type any address, and claim. The page proves in your browser and the relayer sends the withdrawal, so a person with no wallet at all can receive. The exit fee and the relayer fee come out of the note.

A link works like cash: whoever opens it first can claim it.

Taking a link back

The link key is derived from your shielded key, so you can take an unclaimed link back from the app at any time.

Requests

A request link and QR carry your shielded address, an amount and a note, also after the #. The payer opens it and sends inside the pool. A shielded address cannot spend or read anything, so it is safe to share.
