Get paid in USDC,by link.

Leyline is a payment link for USDC. You create a link with an amount and a description; anyone can open it and pay from their own wallet. Funds settle on Arc in under a second and go directly to you, and Leyline never holds them.

01 / THE LINK

A handle, an amount, a description.

The amount is fixed, open, or pay-what-you-want. Terms can't be edited once the link exists, so what a payer sees is what they pay, and you can deactivate it at any time.

02 / THE ROUTER

One contract, one transaction.

It takes the payment, splits off the 0.5%, forwards the rest to you, and emits a receipt, all in the same transaction. Its balance is zero the moment that transaction ends.

03 / THE RECORD

Every payment carries its link's ID.

So three clients paying $500 each resolve to three distinct rows (payer, amount, what it was for) rather than three identical transfers you have to guess between.

What you get paid in
Why this exists

Getting paid across borders is still bad.

The old rails

Getting paid from another country still means a wire that clears in days, a transfer service that may not cover where you live, or a processor that takes roughly 3% and holds the money for a week.

The crypto version

Send someone 0x7a3f…9c21 and hope. One wrong character, or the right asset on the wrong network, and it is gone for good. Nobody should have to get that right by hand.
