A checkout embed is payment infrastructure as a drop-in: a snippet or component that renders a full payment surface (asset choice, amount, invoice, confirmation) inside the merchant's own page, styled to the brand, settled to the merchant's wallet.
The embed model trades a redirect for integration depth: buyers never leave the site, the merchant keeps the analytics, and the payment surface stays maintained by the platform. Done right it is one script tag and a container div.
The U.CASH universal embed drops into any page and offers every rail the merchant enabled: crypto on 34 networks, cards, and the bank rails, white-labeled, with a signed webhook the moment the confirmation policy is met.
Every term behind the rails, the assets, and the settlement.
