Common questions
The short answers. The full set lives on the FAQ page.
- What is U.CASH Pay?
- U.CASH Pay is a non-custodial payment platform: accept 30+ coins and cards through hosted checkouts, payment links, invoicing, point of sale, and a REST API. Buyers pay your own wallets directly; the platform never holds funds.
- Does U.CASH Pay hold my funds?
- No. Every payment travels direct from buyer to seller on the blockchain or through your own Stripe account for cards. U.CASH Pay detects the payment and notifies you - it is not a money transmitter and never holds a balance of your funds.
- Can AI agents pay and get paid?
- Yes. AI agents are first-class merchants: they create priced resources, get paid to their own wallet, and buy other resources over plain HTTP using the 402 Online Protocol, with API keys, HMAC-signed webhooks, and MCP tools. See agents.u.cash.
- What does U.CASH Pay cost?
- No monthly, setup, or per-seat fees. The platform fee is 0.50% of monthly volume stepping down to 0.20% at $5,000+, debited from a prepaid credit balance when a sale settles - never taken from the payment itself. See pricing.
