One link. Every chain.

A checkout is a payment page.

Share the link, embed the button, or call it from your stack. Clean URLs like pay.u.cash/checkout/your-slug — set the title, amount, and currency, or leave the amount open for pay-what-you-want.

Every way to get paid

Checkouts

A reusable payment page: a link you share, a button you embed, or the target of an API call. Fixed price or pay-what-you-want.

Questions

Answers

Who holds the money?
Nobody in the middle. U.CASH Pay is non-custodial: every payment moves direct from buyer to seller, to wallets you control. Funds or keys are never held.
What can my customers pay with?
56 assets across 33 networks — Bitcoin (and Lightning), Ethereum and its L2s, stablecoins on seven chains each, Monero, Solana, and more. Cards and bank rails work through your own Stripe, PayPal, or 2Checkout accounts.
What does it cost?
A platform fee of 0.50%, down to 0.20% by volume — less with UCASH. Checkouts, invoices, and the POS are part of the same account.
What does Hide Branding do?
It makes every checkout, embedded button, and invoice carry your brand instead of ours — your name, your logo, your domain. The payment rails underneath stay exactly the same.
