Accept Abstract (ETH) payments

Accept ETH and tokens on Abstract with a non-custodial checkout that settles directly to your wallet, ideal for consumer-facing apps.

Why accept Abstract

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

Non-custodial

ETH 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 ETH.

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 Abstract wallet can pay. No chargebacks, no geography holds.

Per-coin finality

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