About
As a foreigner staying in Vietnam, you only have two ways to make payment: cash or card. Cash runs out fast and cards are rarely accepted, but every cafe, street food stall, coffee shop, and even luxury restaurants take QR codes. Those QR codes only work with a Vietnamese bank account, leaving you stuck with cash and card every time you buy something.
Prism fixes that.
Prism is a dollar wallet built for foreigners in Vietnam. Fund it with USDC on Base, then pay any local QR code instantly. Your balance is shown in US dollars, and we convert at the live exchange rate at the moment you pay.
1. Fund your wallet
Send USDC on Base from any exchange or wallet you already use. Funds arrive in seconds.
2. Pay like a local
Scan any VietQR code at restaurants, cafes, markets, supermarkets, ride apps, and street vendors. No card, no foreign transaction fees, no fees on the merchant side.
Who Prism is for:
1. Expats living and working in Vietnam who hold USDC
2. Digital nomads who get paid in USDC and base themselves in Vietnam
3. Travelers who want to skip the ATM and pay like a local

What's New in Prism Pay
1.1.0
August 13, 2026
Peru is live. Scan a Yape or Plin QR the same way you scan a VietQR one. Prism now speaks Vietnamese and Spanish. Pick your language from your profile. Self Custodial Earn is live. Put USDC into a fund of short-term US Treasury bills, run by Pods Finance, and take it out when you want. The rate changes over time and returns are not guaranteed. You can pay a merchant straight from your Earn balance. No need to move money out first. Travel plans are in the app. Browse day-by-day itineraries for Vietnam, with places, budgets and the people who made them. We also fixed the Earn deposit screen getting stuck, cleaned up your transaction history, and made the payment details screen easier to read.
