Accept Chainlink (LINK) payments

Accept LINK (ERC-20 on Ethereum) payments, with fiat cards available alongside. U.CASH is non-custodial: funds settle directly to your wallet.

Why accept Chainlink

Merchants choose U.CASH to take LINK without giving up custody or control.

Non-custodial

LINK settles straight to your wallet. U.CASH routes and notifies, it never holds your funds.

Cards too

Offer fiat cards through your own merchant account in the same checkout, side by side with LINK.

White-label

Your logo, colors, and domain. The payment surface is yours; U.CASH is just the rails.

Low, transparent fees

A flat fee per transaction, no spreads, no hidden routing cuts. You see exactly what you pay.

Global by default

Anyone with a Chainlink wallet can pay. No chargebacks, no geography holds.

Per-coin finality

You set what counts as paid. Tune the confirmation policy for LINK per store.
