U.CASH Pay
Accept crypto and cards in one checkout. White-label, multi-store, webhooks and API.
The internet runs on open protocols for everything except money. U.CASH fixes that: non-custodial rails any app or agent can build on, with pay, swap, buy, convert, and names on one shared network across 30+ chains.
U.CASH started in 2015 around a simple idea: give anyone, anywhere, network access and financial utility without a middleman. The portal went live in 2017, and the UCASH network access and loyalty token followed as an ERC-20 in early 2018.
Over the years that followed, the rails grew into collateral, custom tokens, and merchant services across dozens of chains. In 2026 it came together as one open money layer: a single account across pay, swap, buy, names, agents, send, and verify, with machine payments over HTTP-402.
One U.CASH account works across every app. Each is non-custodial, multi-chain, and open.
