United Stables (U)
Verify which dollar asset an invoice requests.
CoinMarketCap rank #47 · 1 November 2026
How it works
U is the symbol of United Stables. A one-dollar target and a one-letter symbol do not establish that a merchant accepts this particular token.
Worked example
If an invoice says only “send dollars”, ask the merchant for the token name and network. Compare the provided details with the issuer’s published asset identifiers.
What to verify
Record the agreed token, network and amount before sending a test payment.
