UCASH is live on three networks: Ethereum, Base, and Polygon.
Confirmations#
Every network has a standard confirmation requirement, enforced automatically and shown live on the checkout:
- Base 3 on every chain - including the whole UCASH and stablecoin families
- TRON: 19, Monero: 10, Dogecoin: 20
- Lightning: instant - a settled invoice completes with zero confirmations
Per coin you can pick a preset - Instant (0), Fast (half), Standard, Secure (double) - or a custom number, and an optional high-value rule multiplies the requirement when the payment exceeds a USD threshold you set. Pending transactions are re-scanned automatically every two minutes; payments up to 48 hours old keep being checked.
Pricing#
Fiat-denominated checkouts quote the coin amount live at creation. Coin-denominated checkouts (type 2) bill the exact crypto amount. Rates come from the platform's rate aggregation with a USD-normalized fallback per coin.
Limiting what you accept#
- Per coin: only coins with a configured receive address (or a generation path) appear at checkout
- Per store: each store can restrict its coin list
- Per instance: white-label operators can curate the network list instance-wide (a bitcoin-only instance is one setting)
- Add your own tokens on 22 networks - see Custom Tokens
